“…Long-term agricultural organic and chemical fertilization significantly affects nitrogen cycling in soils [97,98,[124][125][126]. For example, in calcareous soils, N fertilization increases the potential nitrification rate but reduces the efficiency use of N and changes the beta-diversity of ammonia-oxidizing bacteria (AOB), reducing the relative abundance of Nitrosospira (nitrite-oxidizing bacteria) and increasing the relative abundance of Nitrosomonas (which oxidize ammonia to nitrite) [126]. On the other hand, mineral and organic fertilizer application significantly increased the species richness and alpha-diversity of AOB [125].…”

The present paper reviews the most recent advances regarding the effects of chemical and organic fertilizers on soil microbial communities. Based on the results from the articles considered, some details are presented on how the use of various types of fertilizers affects the composition and activity of soil microbial communities. Soil microbes have different responses to fertilization based on differences in the total carbon (C), nitrogen (N) and phosphorus (P) contents in the soil, along with soil moisture and the presence of plant species. These articles show that the use of chemical fertilizers changes the abundance of microbial populations and stimulates their growth thanks to the nutrient supply added. Overall, however, the data revealed that chemical fertilizers have no significant influence on the richness and diversity of the bacteria and fungi. Instead, the abundance of individual bacterial or fungal species was sensitive to fertilization and was mainly attributed to the changes in the soil chemical properties induced by chemical or organic fertilization. Among the negative effects of chemical fertilization, the decrease in enzymatic activity has been highlighted by several papers, especially in soils that have received the largest amounts of fertilizers together with losses in organic matter.

Effect of the Sulfamethazine on Nitrogen Conversion in Alternate Wet and Dry Paddy Fields

Aquaculture wastewaters have been used in rice irrigation directly or indirectly. Antibiotics in aquaculture wastewater entering the rice fields with irrigation will affect the soil physicochemical properties, microbial properties, and nitrogen conversion. A pot experiment irrigated with simulated aquaculture wastewater was performed to study the effects of sulfamethazine in aquaculture wastewater on nitrogen concentration and conversion-related microorganisms in rice fields with different irrigation modes. Sulfamethazine (500 ng/L, 1500 ng/L, and 3000 ng/L) decreased the NH4+ concentration at the late tillering stage and NO3− concentration at the late tillering and jointing–booting stages (p < 0.05) but increased the NH4+ concentration at the late tillering stage (p < 0.05). Sulfamethazine (3000 ng/L) promoted the lowest nitrogen conversion gene (amoA, nirS, and nirK) abundances and the most special community structure of nitrogen conversion microorganism under mild alternate wetting and drying (AWD). Furthermore, Nitrosospira_sp._KAN8, belonging to ammonia-oxidizing bacteria (AOB), was sensitive to sulfamethazine. Flora with the same nitrogen conversion genes exhibited different variations under the same treatment. The results show that antibiotic and mild AWD caused more serious adverse effects to soil nitrogen conversion and nitrogen conversion microorganisms, which will increase the environmental risks of sulfamethazine. It can provide a basis for the scientific and rational use of aquaculture water to irrigate rice fields.

“…The value of AOA/AOB under each treatment was less than 1 at the jointing stage (z32), indicating that the number of AOB was dominant. Some studies have shown that N application to increase ammonium concentration provides favourable conditions for AOB survival (44,45), so the higher abundance of AOB at the jointing stage (z32) may be related to N fertilizer application. The N forms and concentration in the soil changed as the growth stage advanced, and the abundance of AOB decreased.…”

Optimizing row spacing is an important measure to exploit the full yield potential, achieve a continuous increase in wheat yield and green development without increasing input. The objective of this study was to compare the effects of wide–narrow row spacing pattern (12 cm-12 cm-12 cm-24 cm, R1) and conventional uniform row spacing mode (20 cm, CK; 12 cm. R2) on nitrogen (N) availability in soil, canopy structure, photosynthetic characteristics, radiation use efficiency (RUE) and yield. The results showed that R1 increased the relative abundance of ammonia-oxidizing bacteria and ammonia-oxidizing archaea in the rhizosphere compared to CK. Nitrate in soils treated R1 at post-anthesis and nitrogen use efficiency of the plant were 59.92% and 27.01% higher than those treated with CK, respectively. Above-ground growth of wheat showed that R1 increased leaf area index by 27.42%, specific leaf weight by 22.67% and leaf photosynthetic rate by 8.86%, respectively compared to CK. R2 had similar availability of N and plant growth as CK. Moreover, the ability of the plant to allocate more nitrogen to grains was enhanced at post-anthesis with R1 than it with CK and R2, which greatly improved the RUE by 10.13% and 2.27%. As the result, the yield for R1 increased by 27.54% and 21.46%, respectively, compared to CK and R2. Therefore, using wide–narrow row spacing pattern (R1) is a practically and environmentally feasible approach for wheat production without extra input in the straw-returning wheat-corn rotation system.
