“…Previous studies have shown that combining N fertilizer with quality crop residues can have a positive interactive effect on mineral N (Gentile et al, 2008). In contrast, straw incorporation in soil has been found to increase microbial biomass and N mineralization, leading to a higher nutrient supply in soil (Eagle et al, 2000;Choudhary et al, 2018;Dhaliwal et al, 2023b). These observations suggest that both organic and inorganic nutrient management can increase nutrient availability in soils, supporting our findings.…”

To achieve higher crop production in a soybean-wheat cropping system, comprehensive knowledge of soil fertility status and its variability is crucial. However, a significant gap exists between the potential and actual productivity of this system in the Vertisols of Indian semi-arid tropics. Therefore, 2 years of field research were conducted to investigate how different crop management practices affect soil fertility in this cropping system. The trial was conducted using a randomized complete block design (RCBD) with five crop management practices: CAO (conservation tillage + organic nutrient and weed management), CAC (conservation tillage + chemical nutrient and weed management), CTC (conventional tillage + chemical nutrient and weed management), OCT (conventional tillage + organic nutrient and weed management), and PoPs (package of practices). Results showed that CAO significantly (p < 0.05) increased soil organic C (6.8 g kg−1), available N (129.5 mg kg−1), P (11.0 mg kg−1), K (232.6 mg kg−1), Fe (9.17 mg kg−1), and Mn (10.48 mg kg−1) at topsoil (0–15 cm) and deeper layers (15–60 cm). In contrast, CAC had significantly (p < 0.05) higher soil availability of Ca (5,072 mg kg−1) and Mg (901 mg kg−1) and Cu (0.84 mg kg−1). On the other side, PoPs resulted in the highest S (10.05 mg kg−1) and Zn (0.85 mg kg−1) availability in the topsoil. Our results evidently suggested S and Zn availability as key indicators of soil health sustenance in the present agroecosystem. Notably, CAC had significantly (p < 0.05) higher system productivity (4.62 t ha−1) than the other treatments, showing a 14.0, 6.3, and 18.2% increase over CAO, CTC, and OCT, respectively. Based on the results, it is recommended that CAC is a better option for achieving higher system productivity, while CAO is the best option for ensuring long-term sustainability of soil fertility. The findings of this study could be useful for farmers and agricultural researchers in designing efficient crop management practices to improve the productivity and sustainability of soybean-wheat cropping system in arid to semiarid ecology.

“…In order to ensure soil nutrient supply and crop yield, accelerating cultivated land restoration and improving product quality are important issues facing current agricultural production. At present, an effective way to improve soil fertility and nutrient vitality is by increasing the application of organic fertilizers, purifying the soil environment and ensuring high yield and quality of crops based on various amino acids and humus [1][2][3]. Previous studies showed that organic fertilizers contain a large number of amino acids and organic matter, as well as nitrogen, phosphorus, potassium and other nutrients required for plant growth [4].…”

“…On the other, they alleviate soil compaction and augment its porosity, thereby optimizing nutrient uptake [2]. Previous research indicated that after composting it, compound organic matter can improve soil fertility, promote the accumulation and conversion of nutrients and promote the production of basmati rice [1,3]. Therefore, the compound application of bio-organic fertilizer can optimize the soil environment, increase soil fertility and increase crop yields.…”

Amidst the burgeoning expanse of the poultry sector, the escalation of chicken manure production has ensued, potentially exacerbating ecological contamination. However, the application of chicken manure is bound to transmute the habitat of edaphic microorganisms, precipitating an alteration in the soil’s microbial consortium. The composting of biochar-amended chicken manure and wood chips (biochar composting products, BCPs) was used to improve Chinese cabbage (Brassica campestris L.) production and regulate soil properties and bacterial community structure. On the 40th day of Chinese cabbage growth, soil and Chinese cabbage were collected for laboratory analysis. The effects of different proportions of BCPs (0, 1%, 3%, 5% and 7% biochar) on soil fertility, enzyme activity, the microbial community and the growth of Chinese cabbage were studied under facility conditions. The results showed that the growth performance and quality of Chinese cabbage were significantly increased with increasing BCP ratios. Soil fertility indicators including pH, AN, AP, AK and SOM were significantly increased, except for the pH value in the 1% BCP group. The activities of phosphatase, catalase and urease were increased for all groups of BCP treatment. The soil microbial community response was significantly different, and the application of 5% and 7% BCPs reduced the abundance, diversity and evenness of soil bacteria. Chinese cabbage growth performance was positively correlated with an increase in BCP supplemental levels in the range of 3–5%. Also, the abundance, diversity and uniformity of the soil microbial community were improved in the 3% BCP treatment group. Therefore, the dominant bacterial phyla were Bacteroidetes, Actinobacteriota, Gemmatimonadota, Myxococcota, Bdellovibrionota and Firmicutes, especially the Bradyrhizobium of Proteobacteria. BCP treatment reduced the degradation of soil organic matter. In addition, it also improved the relative abundance of sequences associated with improving soil fertility. Collectively, these findings offer insights for the re-evaluation of application management strategies for BCP organic fertilizers.

“…However, the massive poultry production results in a huge amount of excrement, which is considered a major source of poultry waste [7]. At present, increasing applications of organic fertilizer is an effective way to improve crop yield [13][14][15]. Previous studies have shown that organic fertilizers can optimize rhizosphere bacterial community structure and improve soil fertility and soil continuous production capacity [13,16].…”

This study investigated the impacts of biochar addition on N conversion, humification, and bacterial community during Flammulina velutipes waste composting. The mixture of chicken manure and Flammulina velutipes waste was 4:6 (dry weight basis). The biochar was added into the mixture and mixed thoroughly at ratios of 0, 2.5, 5, and 7.5% (w/w) and labeled as CK, T1, T2, and T3, respectively. The results showed that the biochar treatment significantly improved the compost maturity by increasing humic substances and the conversion of NH4+-N to NO3−-N. With the increase in biochar supplemental level, the abundance, diversity, and uniformity of the microbial community were improved. The dominant taxa were Firmicutes, Bacteroidota, Actinobacteriota, Proteobacteria, and Gemmatimonadota, especially the Firmicutes and Bacteroidota. Biochar addition facilitated the proliferation of thermophilic bacteria such as Bacillus, Actinobacteriota, Parapedobacter, and Sphingobacterium, leading to enhanced organic decomposition to increase humus. The findings of this study highlighted the positive effects of biochar addition on the composting mixture of chicken manure and Flammulina velutipes waste. These results can help to produce high-quality biochar composting products by balancing organic decomposition and humification based on the bacterial community.
