“…At soil pH ≥ 6.0, CRU effectively reduces N 2 O emissions and NH 3 volatilization [25]. Blending urea reduces the ammonia volatilization losses very effectively up to 17-20% as compared to the uncoated urea [26]. Polymer coating of urea is a cheaper and effective technique to lower the N losses, and for enhancing the nitrogen-use efficiency [27,28].…”

Nitrogen (N) is an essential plant nutrient, therefore, N-deficient soils affect plant growth and development. The excessive and unwise application of N fertilizers result in nutrient losses and lower nutrient use efficiency that leads to the low crop productivity. Ammonia volatilization causes a major loss after N fertilization that causes environmental pollution. This experiment was conducted to evaluate the effectiveness of coating and uncoating N fertilizer in enhancing yield and nutrient-use efficiency with reduced ammonia emissions. The recommended rate of nitrogen and phosphorus, urea and di-ammonium phosphate (DAP) fertilizers were coated manually with 1% polymer solution. DAP (coated/uncoated) and potassium were applied at the time of sowing as subsurface application. While urea (coated/uncoated) was applied as surface and subsurface application. Results showed that nutrient use efficiencies of wheat were found to be maximum with the subsurface application of coated N fertilizer which increased nutrient-use efficiency by 44.57 (N), 44.56 (P) and 44.53% (K) higher than the surface application of uncoated N fertilizer. Ammonia emissions were found the lowest with subsurface-applied coated N fertilizer. Thus, coated fertilizer applied via subsurface was found the best technique to overcome the ammonia volatilization with an improvement in the yield and nutrient-use efficiency of wheat.

“…Numerous experiments have confirmed that fertilization management could alter the chemical properties of the soil solution, activate the microbial community, and significantly impact the microbial community structure and its complexity ( Geisseler and Scow, 2014 ; Liu et al, 2019 ; Xiong et al, 2019 ; Fan et al, 2020a ; Ji et al, 2021 ; Li B. B. et al, 2021 ; Zhang et al, 2021 ). For example, compared with individual applications, the combined inorganic fertilizers and cow manure led to the most resistant microbial community, which was associated with the highest levels of nutrient availability and plant production ( Fan et al, 2020a ).…”

“…Compared with regular urea, controlled-release urea can reduce the damage to the crop root system in the pre-fertility stage, extend the nutrient absorption and utilization validity period, and has the advantages of N setback, improving the efficiency of N fertilizer utilization, reducing the number of manual fertilizer follow-ups, and improving economic efficiency ( Blackshaw et al, 2011 ; Guo et al, 2017 ). Consequently, a blend of regular and controlled-release urea can address both the rapid loss of N fertilizer and the N requirements for later maize growth and development ( Zheng et al, 2016 ; Zhang et al, 2021 ). For instance, a growing number of studies suggested that combining urea and controlled-release urea fertilizers improves maize yield and N use efficiency and reduces ammonia volatilization ( Zheng et al, 2016 ; Zhang et al, 2019 ; Guo et al, 2021 ).…”

Increased complexity of microbial networks can contribute to increased biodiversity and multifunctionality and thus crop productivity. However, it is not clear which combination ratio of regular and controlled-release urea will increase the soil microbial community complexity and improve maize yield in the North China Plain. To address this knowledge gap, a 2-year field experiment was conducted to explore the effects of the combination of regular (U) and controlled release (S) urea ratios [no fertilizer control (CT), regular urea alone (U), controlled-release urea alone (S), controlled-release urea mixed with regular urea 3:7 (SU3), controlled-release urea mixed with regular urea 5:5 (SU5), and controlled-release urea mixed with regular urea 7:3 (SU7)] on XianYu 688 yield and its rhizosphere and bulk soil microbial community composition and network complexity at different fertility stages. The combination of controlled-release and regular urea increased the N agronomic efficiency, N partial factors productivity, maize yield, and grain number per spike, with the maximum maize yield (9,186 kg ha–1) being achieved when the ratio of controlled-release urea to regular urea was 3:7 (SU3, p < 0.05). Maize yield increased by 13% in the SU3 treatment compared to the CT treatment. Rhizosphere soil microbial diversity remained stable at the silking stage of maize while increased at the physiological maturity stage of maize, with the increasing controlled-release to regular N fertilizer ratios (from 3:7 to 7:3, p < 0.05). This result suggests that a combination of regular and controlled-release N fertilizer can still substantially increase soil microbial diversity in the later stages of maize growth. The combination of controlled-release and regular urea is more effective in improving microbial network total links and average degree, and N agronomic efficiency (R2 = 0.79, p < 0.01), N partial factor productivity (R2 = 0.79, p < 0.01), spikes per unit area (R2 = 0.54, p < 0.05), and maize yield (R2 = 0.42, p < 0.05) increased with the microbial network complexity. This result indicates that the higher microbial network complexity is strongly associated with the higher N agronomic efficiency and N partial factors productivity and maize yield. In conclusion, the ratio of controlled-release to regular urea at SU3 not only increases the yield of maize and N agronomic efficiency but also enhances microbial diversity and network complexity in the North China Plain.

“…The use of ecologically directed organic mineral fertilizers to improve the structure of the fertile soil layer and to steadily increase the yield of grain crops and, in particular, wheat, remains an urgent task in modern agriculture. Studies of scientists from various countries are devoted to solving this problem [6][7][8][9][10][11]. The results of a long-term field experiment presented in [6] stated that in all variants, additional manure application stabilized the wheat yield and provided the lowest agronomic risk for yield failure.…”

“…In [7], it was noted that, although organic fertilizers are more environmentally friendly, they have too low a concentration of nutrients and slow release of nutrients to support crop production in a short time. In [8], it is proved that the use of organic fertilizers in combination with mineral fertilizers should be considered as an effective strategy for a sustainable wheat production system, contributing to the mitigation of negative environmental consequences. Studies [9] found that the replacement of mineral fertilizers with manure during wheat cultivation led to an increase in economic profit by 17.2%, while the environmental impact decreased by 24.6%.…”

The article presents the results of a field vegetation experiment in the Rostov region on the cultivation of spring wheat of the “Zlata” variety with the use of an environmentally oriented organic mineral fertilizer from liquid waste of pig farms by the method of split plots with a randomized placement of variants in repetitions, the repetition of the experiment is three-fold. The agrochemical indicators of the soil before and after wheat cultivation at the horizons of 0-20 and 20-40 cm are given. The scheme of carrying out the experiment, including different doses of organic mineral fertilizer application and a plan for cutting plots, is indicated. During the growing season, constant observations of the plants were carried out together with the care. The dynamics of the growth of wheat biomass in different periods of time from planting and its yield are presented. The influence of different doses of ecologically oriented organic mineral fertilizer from pig manure on the yield of spring wheat is estimated. According to the results of experimental data, the effective dose of organic mineral fertilizer application from pig manure was established-2t/ha. The yield of grain crops (wheat) per hectare was determined-49.2 c / ha. The spring wheat variety “Zlata”, which is unusual for the Rostov region, gave a high yield when applying an environmentally oriented fertilizer, which proves its value both in agronomic and ecological terms. The absence of toxic effects on the soil of organic mineral fertilizers for heavy metals (copper, nickel. cadmium, lead), an increase in humus from 5.43% to 5.52%. The assessment of the nutrient reserves in seeds and the effect of organic mineral fertilizer doses on the quality of spring wheat grain of the «Zlata» variety is given. The highest amount of gluten-40.03% - was observed when using the fertilizer at a dose of 2 t / ha.
