Ammonia emission from sandy loam soil amended with manure compost and urea
Applied Biological Chemistry volume 65, Article number: 83 (2022)
Urea is a renowned nitrogen (N) fertilizer widely used in plant N nutrition owing to its high N concentration (46%). The effect of the N application rate on ammonia (NH3) emission into the environment and soil properties is yet to be unraveled. The rate of NH3 emission from sandy loam soil amended with manure compost (T1: 5000 kg ha−1) and urea at different application rates (100, 200, and 400 kg N ha−1 designated as T2, T3, and T4, respectively) with 3 replications was evaluated in an incubation experiment. Ammonia emission was rapid at the early stage of the experiment followed by an equilibrium decrease that tends toward zero at the end of the incubation. Ammonia emissions of 16.50, 52.15, and 75% of applied N in T2, T3, and T4 were observed on day 49. Ammonia emission increased linearly (y = 0.7823x−32.169, R2 = 0.95**) in response to N application rates. T1 conserves more NH4+ (20.79 mg kg−1) in the soil, followed by T2 (11.8 mg kg−1) and T3 (11.7 mg kg−1). T2 and T3 reduced the soil pH to optimal for microbial activities and nutrient availability, while T4 promoted soil acidity. A balanced combination of compost and urea mitigates NH3 volatilization and improves soil fertility. In conclusion, applying compost (5000 kg ha−1) with urea at 100 kg N ha−1 or 200 kg N ha−1 is recommended for NH3 volatilization mitigation, nitrification inhibition, and efficient NH4+ retention in the soil.
The rapid soil nutrient degradation and the necessity to meet the world’s growing population's nutritional needs resulted in the excessive use of chemical fertilizer. Volatilization of ammonia (NH3) from mineral nitrogen (N) fertilizer accounts for 19–20% of the total NH3 released into the atmosphere . Generally, agriculture is reported to be responsible for 80–95% of total NH3 emissions to the atmosphere  thereby, causing soil health problems and adverse effects on the environment. Besides, it causes eutrophication and acidification of the soil and water environment . Ammonia emission into the atmosphere is the second source of N2O, contributing to global warming and ozone depletion in the stratosphere . Moreover, the application of a high dosage of urea to the soil gives rise to the emission of CO2 coupled with NH3 . As earlier reported, N loss after the addition of urea may be more than 50% of applied N [36, 43]. Several basic factors that influence NH3 volatilization are methods of fertilizer application, the cultivation system, soil type, soil pH as well as soil thermal and moisture conditions [25, 28]. Urea application methods are key factors that influence NH3 emission either by increase or decrease. Urea granules are often broadcast on the soil surface or are introduced under the soil by an appropriate agrotech method. However, placing urea at the soil surface increases the risk of NH3 volatilization. The implication of the co-application of compost and urea is an attempt to delay urea hydrolysis, which minimizes the formation of NH3 and carbonic acid in the soil. Given the need to increase N use efficiency by crops and reduction of environmental impact, there is a search for strategies that allow an increase in the efficiency of the fertilization process. The use of compost is considered a promising strategy to improve N utilization. Compost is a value-added product used in the farming system that could optimize N fertilizer usage whose demand is now on the increase worldwide. The production of compost using unwanted agricultural materials is a sustainable technology that improves plant nutrition and food security . Over decades the addition of compost or manure has been reported to increase soil nutrient availability and increase crop yield . However, there is a dearth of information on its combined use with urea in mitigating NH3 volatilization. This study aims at providing (i) recommendations on the quantity of urea that should be added to the soil at the prevalent cropping period in summer to mitigate NH3 volatilization and improve soil health. (ii) Developing a strategy that minimizes N loss via NH3 volatilization using a fixed rate of compost in combination with different rates of urea. (iii) Estimating compost and urea’s complementary effect on selected soil properties.
Materials and method
Soil sampling, preparation, and characterization
The soil used in this study was sampled at 15 cm depth from Miyang-myeon, Anseong-si (36° 58ʹN, 127°13ʹE), Gyeonggi-do, Republic of Korea. The soil samples were air-dried and screened through a 2 mm sieve in preparation for the initial soil characterization and incubation experiment. The soil textural class was determined by the hydrometer method . The electrical conductivity and pH of the soil were measured at a ratio of 1:5 (soil to water)  using a pH and conductivity meter (Orion star A214 and A215, respectively). The total N was determined using the Kjeldahl method . Exchangeable cations (K, Ca, and Mg) were extracted by 1 N ammonium acetate  and analyzed on inductively coupled plasma–optical emission spectrometry (ICP–OES). Available P was extracted following the Lancaster method  and analyzed on an ultraviolet–visible spectrophotometer (UV–VIS spectrophotometer). The soil organic matter was determined by the modified Walkley and black method .
Sources and characterization of the amendments
The urea (46% N) and compost are commercial products purchased from Namhae chemical, Yeosusandan -ro, Yeosu-si, Jeollanam-do, and Jugjubilyo Yesnalgeoleum Yuna, Seodond-daero, Samjuk -myeon, Anseong -si, Gyeonggi-do, Republic of Korea, respectively. The compost consisted of pig manure, poultry manure, cattle dung manure, sawdust, and microorganism product combined at 20, 20, 20, 38, and 2%, respectively. The compost was oven-dried at 600C for 24 h and allowed to cool down in a desiccator before grinding in preparation for analysis. The pH and the EC of the compost were measured in a ratio 1: 10 (compost: water) using a pH and conductivity meter, respectively. The total nitrogen content of the compost was determined using the Kjeldahl method (Bremmer et al. 1996). The organic matter content was estimated using the loss on ignition method , while the organic carbon content was estimated from the organic matter content by calculation (%TOC = OM/1.724).
Experimental setup and design
The incubation experiment was performed in the laboratory of Agricultural Chemistry, Hankyong National University, Anseong, at room temperature (25 ℃). The experiment was laid out in a complete randomized design consisting of 4 treatments with 3 replications. The compost was applied to all the samples at the rate of 1.92 g chamber−1 (equivalent to 5000 kg ha−1). Urea was applied at different rates (83.6, 167.2, and 334.4) mg chamber−1, these rates are equivalent to 100, 200, and 400 kg N ha−1, respectively. Therefore, the treatments evaluated are as follows:
T1: 500 g soil + 5000 kg ha−1 compost.
T2: 500 g soil + 5000 kg ha−1 compost + 100 kg N ha−1
T3: 500 g soil + 5000 kg ha−1 compost + 200 kg N ha−1
T4: 500 g soil + 5000 kg ha−1 compost + 400 kg N ha−1
In this study, T1 is the control, without urea. Compost was thoroughly mixed with soil (500 g) samples in all the treatments, T1 was brought to 60% field capacity with ordinary distilled water while the mixture of urea and distilled water was used to bring the rest treatments to 60% field capacity. Urea was dissolved in water before application into the soil to give room for even distribution of fertilizer and minimize N loss via NH3 emission .
Ammonia volatilization measurements, soil analysis, and calculations
The dynamic chamber method was employed for NH3 volatilization collection. The NH3 collection device (Fig. 1) includes a soil incubating jar with an air inlet opening by the side to allow air exchange within the soil chamber. It also consisted of another jar that contained 30 mL of 0.05 mol/L H2SO4 for NH3 gas trapping, this jar was stopped and fitted with an inlet and outlet pipe. The outlet pipe was connected to the airflow meter while the inlet pipe was connected to the soil chamber. The airflow meter was also connected to the vacuum pump. The basic principle behind the NH3 volatilization collection device is for the vacuum to serve as a power source. Here, the NH3 in the soil chamber is replaced by air while the evaporated air enters the absorption jar together with the pumping airflow. This device ensures aeration and traps NH3 loss through the volatilization process. The NH3 gas was sampled for one hour per sampling period with an airflow of 2 L min−1. Ammonia volatilization was monitored consecutively for the first 5 days and continued every week till day 49 after treatment application. The gas trapped in 0.05 mol/L H2SO4 at each sampling time was analyzed calorimetrically on a UV-spectrophotometer using the nesslerization method. Briefly, an aliquot of 5 ml of the NH3 trapped in 0.05 mol/L H2SO4 was pipetted into a test tube followed by the addition of 200µml of the ammonia color reagent (nesslerization reagent) . The mixture was shaken vigorously on a vortex shaker and left for 15 min to enhance coloration at room temperature. Absorbance was thereafter read on a UV–VIS spectrophotometer at 425 nm. The NH3 emission was calculated using the equation below, 
Where, ER: emission rate (mg min−1). Q: Air flow rate into the chamber (L min−1). Ce: gas concentration of air leaving the chamber (mg kg−1). Ci: gas concentration of air entering the chamber (mg kg−1). Wm: Molecular weight of the gas (g mol−1). Vm: molar volume at standard temperature (0 °C) and pressure (101.325 kPa), 22.4 Ɩ mol−1. Tstd: standard temperature, 273.15 K. Ta: temperature of the sample air, K (273.15 + sample air ℃). Pstd: standard pressure, 101.325 kPa. Pa: local barometric pressure, kPa.
At the termination of the incubation experiment, soil samples were collected from each chamber, prepared, and analyzed for soil pH, EC, and organic matter following the procedures mentioned above. Soil NH4+–N and NO3−–N were extracted by 2 M KCL and their concentrations were determined on UV–VIS spectrophotometer using indophenol-blue and brucine methods, respectively . Thereafter NH4+ and NO3− were estimated by calculation.
The data obtained in this study were subjected to one-way analysis of variance (ANOVA) using Genstat10.3.00 software (VSN international limited) and means were separated by Duncan multiple range tests (F ≤ 0.05).
Experimental soil and compost characteristics
The selected properties of the soil and the compost are represented in Tables 1 and 2, respectively. The soil showed a sandy loam texture. It is alkaline in nature with a pH of 7.40, EC 0.4 dSm−1, TN (0.08%), P (620.09 mgkg−1), OM (11gkg−1), 1.54, 2.60 and 1.50 cmolkg−1 of K, Ca and Mg respectively (Table 1). The compost is also alkaline in nature (pH 7.36) with an EC level of 23.76 dSm−1 The compost has a high organic matter (623 gkg−1), total carbon (361 gkg−1), and TN concentration of 22 g kg−1 which resulted in a moderate C: N ratio (Table 2).
Daily ammonia (NH3) volatilization from each treatment for 49 days of incubation is presented in Fig. 2a. Ammonia volatilization occurred rapidly at the inception of the experiment in each urea treatment. Ammonia emission was highest on day 4 in T2 while T3 and T4 peaked on day 3. At the maximum level, the daily NH3 volatilization measured was 0.6, 5.2, and 9.2 kg NH3 ha−1 for T2, T3, and T4, respectively. However, Samples treated with compost alone (T1) showed no significant (P < 0.05) NH3 loss until day 2 after treatment application with the maximum NH3 loss (0.4 kg NH3 ha−1) on day 4. Compared to T4, T2 and T3 were observed to reduce NH3 volatilization by 58.04% and 22.38%, respectively. Overall, active NH3 volatilization in all treatments occurred between day 1 and day 14 followed by an equilibrium decrease that tends toward zero till the end of the incubation experiment (Fig. 2a).
Cumulative NH3 emission increased steadily and peaked at day 7 in all the treatments. Cumulative emission amounts of 0.88, 2.45, 11.66, and 33.41 kg NH3 ha−1 after 7 days were observed in T1, T2, T3, and T4, respectively (Fig. 2b). Overall, on day 49, the total amount of NH3 emission (9.23 kg NH3 ha−1) was observed in soils treated with compost alone while, the total 16.50 kg NH3 ha−1, 104.3 kg NH3 ha−1 and 298.12 kg NH3 ha−1 were volatilized at the urea application rates of 100 kg N ha−1 (T2), 200 kg N ha−1 (T3), and 400 kg ha−1 (T2), respectively (Table 3). These values are equivalent to 16.50, 52.15, and 74.5% of applied N at the equivalent 100 kg N ha−1 (T2), 200 kg N ha−1 (T3), and 400 kg ha−1(T4), respectively (Table 3). This showed that NH3 loss was significantly minimized in T1, T2, and T3. As shown in Fig. 2c, NH3 lost through volatilization increased markedly giving a linear equation (y = 0.7823x−32.169, R2 = 0.95**), indicating that NH3 emission increased with an increase in N application rate.
Soil NH4 + , NO 3 − , pH, EC, and organic matter.
The treatment effect on NH4+ was significant (P < 0.001) among treatments and highest in chambers with compost (20.79 mg kg−1) followed by compost with urea treatments at 100 kg N kg−1 (11.8 mg kg−1) and 200 kg N kg−1 (11.7 mg kg−1). There was no significant (P < 0.05) difference between the NH4+ content of T2 and T3. The least values of NH4+ were recorded in soils treated with compost and urea at 400 kg N ha−1 (T4) (Fig. 3a). Conversely, on day 49, the NO3– concentrations in the soil across the treatments followed a reversed pattern compared to the observation in NH4+ concentrations. The concentrations of NO3− followed the order 400 kg N ha−1 > 200 kg N ha−1 > 100 kg N ha −1 > 0 kg N ha−1. Soil available NO3− increased with an increase in N rate application (Fig. 3b). The effect of the sole application of compost and its combination with urea at different rates was highly significant (P < 0.05) on the soil pH and EC values of the soil at day 49. Soil treated with 400 kg N ha−1 had the least pH value (5.71) and highest EC (2.61dS m−1) value while the soil treated with compost had the highest pH value (7.18) and least EC values (0.45 dS m−1) (Fig. 4a and b). At the end of incubation, EC values of co-application of compost and urea treatment at 400 kg N ha−1 were found to be 36% greater than that of compost only, 24% greater than compost and urea at 100 kg N ha−1 and 13% greater than compost and urea at 200 kg N ha−1 (Fig. 4b). Moreover, NH3 emission was proportional to an increment in EC level in all treatments while pH was inversely related to cumulative NH3 emission after 49 days of incubation (Fig. 4a and b). Although, there was no significant (P < 0.05) difference in the mean values recorded in the OM content of compost treatment only (12.33 g kg−1) and compost plus urea (12.24 g kg−1) at 400 kg ha−1, soil treated with compost and urea at 100 kg N ha−1 had the highest values (13.21 g kg−1) followed by compost plus urea at 200 kg N ha−1 (12.77 g kg−1) (Fig. 4c).
The use of urea fertilizer is indispensable in the farming system; however, it has been suspected to be a potential contributor to the emission of NH3 into the environment. Our study investigated the effect of compost and urea on NH3 volatilization, soil pH, EC, NH4+, NO3−, and soil organic matter (SOM) at the prevalent cropping temperature (25 ℃) during summer. Ammonia volatilization was very rapid at the early stage of the experiment which indicated the hydrolysis reaction of dissolved urea with water to form ammonium ions (NH4+). This effect could be accrued to the intrinsic characteristics of urea which rapidly hydrolyses when applied to the soil as urease enzymes change the urea to carbonate . Furthermore, our observation that active NH3 emission among treatments occurs within the first 14 days after treatment addition attests to the fact that it takes a shorter period for urea to be hydrolyzed after application into the soil . After the 14 days of active volatilization, there was equilibrium in the NH3 volatilization rate which tends towards zero at the end of the experiment. This result corroborates the findings of Ferguson et al.  who reported stabilization in NH3 volatilization after 12 to 16 days of fertilization addition. The retardation in the NH3 emission rate toward the end of the incubation experiment could also be attributed to the gradual dryness of the soil surface resulting from aeration by the air pump as NH3 emission loss decreases where there is insufficient soil moisture. Reduction in NH3 volatilization due to insufficient soil moisture for chemical reactions has been reported by early researchers [8, 9, 37, 40].
The increase in NH3 volatilization following the increase in the N rate observed in this study corroborates previous studies [11, 24]. The highest total NH3 (298.12 kg N ha−1) volatilized from T4 compared to other treatments suggests that the rate of urea application is one of the key factors that influence NH3 volatilization. Besides, the alkalinity of the soil used in this experiment is a vital reason for 75% N loss in T4 as the addition of urea changes the soil pH of the soil at the initial stage of application, therefore, aggravating the rate of hydrolysis thus increasing NH3 emission into the atmosphere. This high N loss (75%) is inconsistent with most of the previous reports either in the laboratory (56% at 15 kg N ha−1) , greenhouse (58% at 55 kg N ha−1)  and field trial (47% at 56 kg N ha−1) . The discrepancy could be explained by the differences in the initial soil pH, soil structure, soil buffer capacity, and the rate of N application. Although our study did not monitor the changes in pH across the incubation period, however, the pH of alkaline soil has been reported to be higher at the initial stage of N addition . It is therefore evident that alkaline soil is likely to lose a larger percentage of N applied especially when N is added at a high rate such as 400 kg N ha−1. Additionally, the highest NH3 emission in T4 implies poor retention of NH4+ after hydrolysis thus escaping into the atmosphere. The effect of compost in delaying the emission of NH3 in T2 and T3 was apparent compared to T4, as the NH3 emission was observed to be low in T2 and T3 at the inception of the experiment. The Lower NH3 emission rate in T1, T2, and T3 results from the effect of compost on the slow release of hydrolysable N from the organic matter of the compost . Similarly, the reduced total emission observed in T2 and T3 could also be attributed to the ability of compost to adsorb NH4 + to its surface. Additionally, the porous and irregular morphological surface and large interface of the compost that serves as bio adsorbents for NH4+ adsorption could also account for the lower emission rate in T2 and T3. Jauberthies et al.  reported earlier that organic amendments' chemical composition is vital as they reflected organic fibers with a high external surface area which has the ability for NH4+ adsorption. Generally, one wouldn’t have expected NH3 volatilization from the control chambers (T1), however, the least total ammonia emission observed in the control chamber indicates that the organic matter (OM) in both the soil and the compost could contribute to NH3 volatilization. Besides, ureolytic enzymes in compost could also trigger NH3 volatilization . In this study, the percentage of N loss increases with an increase in the application rate of the N fertilizer. This finding is supported by the report of Fan et al.  who observed NH3 emissions increase to be proportionate with an increase in N applied. The amount of volatilization showed a positive relationship with the N application rate . This confirms that it is not beneficial and cost-effective when urea is added to the crop beyond the recommendation rate. It should therefore be emphasized that the application of compost and urea should be at a recommended rate for effective N-use efficiency and sustainable agriculture.
Furthermore, among all the soil properties (such as SOM, pH, cation exchange capacity (CEC), and soil texture: [1, 16, 18, 35, 47] reported affecting NH3 volatilization from the soil after urea application, non-appear to dominate or have consistent control on NH3 volatilization from the soil . Post-soil analysis was performed on day 49 to investigate the effect of urea on selected soil properties after the initial increase in soil pH following the application of N-based fertilizer into the soil. For example, on day 49, the soil pH in all the treatments decreases as the EC level increases. This implies that a higher amount of hydrogen ions in the soil enhanced the higher content of soluble salt which thus leads to a higher level of soil electrical conductivity (EC). Mohd-Aizat et al.  and Bruckner  also observed lower soil pH as an indication of a large number of hydrogen ions in the soil and vice versa. Electrical conductivity increases as does the cumulative NH3 volatilization while pH decreases as cumulative NH3 volatilization increase across all treatments. The decreased pH values observed in all the treatment at day 49 does not negate the report of previous studies on increase in pH after urea addition into the soil . It should be noted that a temporary increase in pH usually occurs immediately after urea addition and decreases with time. In a study performed by Kim et al. , NH3 emission increased immediately after fertilizer application, peaked on day 7, and later decrease gradually over time. The rapid increase in soil pH following urea addition is described as a universal phenomenon that occurs in all urea-treated soil after which the pH decreases with time either via infiltration or nitrification process. Generally, soil pH plays an important role in nutrient availability and nutrient adsorption that usually enhances the photosynthesis process thus increasing plant growth and yield . However, many reactions influence soil pH following urea addition to the soil. Immediately after the addition of urea into the soil, the pH around urea granules tends to increase above 8 which thus increases the formation of carbonate . Additionally, changes in soil pH during urea hydrolysis could also trigger the conversion of NH4+ to NH3 thus leading to an increase in NH3 emission . The reduction in pH level in T4 is an indication that the application of urea at a high rate could lead to soil acidification and metal toxicity thus reducing the soil fertility which in turn affects the productivity of the soil. As soil pH level is an important factor controlling nutrient availability and microbial activities in the soil, however, this effect varies with soil types. At the end of the incubation experiment, T2 and T3 brought the pH of the soil near the optimal pH for nutrient availability, crop tolerance, and soil microbial activity. The nitrification process results in the oxidation of ammonium to nitrate instigating the release of proton thus reducing the pH value of the soil . The reduction in the NH4+ concentrations of the soil on day 49 coincides with the increase in the soil available NO3−. Our study showed that most of the organic N from T1, T2, and T3 respectively, were in NH4+ form which will continue to be mineralized and available for plant use. However, if not taken up by the plant and not properly held by the soil exchange site it can be leached as NO3− or denitrified . Moreover, an increase in SOM is known to reduce NH3 volatilization, however, our observation of OM content among treatments in this study is negligible. Although the effect of SOM on NH3 volatilization is negligible, the soil pH across all the treatments decreased near the optimal level for nutrient availability and microbial activities except in T4 where pH was found acidic. This effect may be attributed to the formation of various organic acids and humus during the decomposition of OM. In addition, OM, soil texture, CaCO3, and total salt content can be considered complementary while pH and CEC as essential soil properties that affect NH3 volatilization following the addition of N-based fertilizer . In a study performed by Zhenghu and Honglang  soil CEC, OM, and clay content were found to be negatively correlated with NH3 volatilization which implies their ability to inhibit NH3 volatilization. Similarly, in our study SOM recorded in T2 and T3 was higher compared to T4 where the highest NH3 volatilization was observed. This effect could be attributed to the improvement in soil texture following the addition of manure compost and urea. The soil clay content enhances the absorption of NH4+ and NH3, simultaneously reducing the concentration of NH4+ in the soil solution and N loss via NH3 volatilization . The acidic nature of T4 on day 49 confirms the fact that a higher rate of urea addition to the soil is detrimental to the soil and its organisms. Therefore, adequate application of organic manure combined with urea could mitigate NH3 volatilization and improve soil fertility and productivity.
