“…The application of biochar itself at an optimal level, or in combination with inorganic fertilizer, can increase photosynthesis, leading to better plant growth and a more satisfactory seed yield, thereby reducing environmental pollution. Similar results are reported by [40], who state that the use of straw, whether in a fresh or decayed condition, has the ability to increase the soil water content and plant uptake of N, P, and K on Alfisol soil. Meanwhile, [41] find that returning straw to the soil in rice fields, when accompanied by controlled irrigation, can divert the use of chemical N fertilizer from top-dressing to become basic fertilizer to fulfil the nutrient uptake of the rice crops.…”

This study aims to determine the potential and limitations of land in Ngawi District, East Java, Indonesia, for cultivating rice, corn, and soybeans. The research consists of a four-stage field study conducted in Ngawi Regency: (1) organization of land units; (2) determination of observation points through stratified proportional sampling for each land unit; (3) field surveys; and (4) laboratory analysis. The land evaluation was conducted in accordance with the FAO Guidelines for Land Evaluation for Rainfed Agriculture. The results of the research indicate that 46,417.7 ha (88.1%) of the land area is highly suitable (S1) for rice and 49,286.6 ha (72.1%) is marginally suitable (S3) for corn due to poor drainage. Approximately 62,499 ha (91.4% of the total land area) are marginally suitable (S3) for soybean cultivation. There were suggested five models of land management: (1) intensive rice farming; (2) a relay cropping system for rice-corn or rice-soybeans; (3) multiple cropping systems for corn, soybeans, or rice; (4) a mono-cultural system for rice, corn, or soybeans; and (5) an agroforestry system for Albizia chinensis, corn, and soybeans. Farmers’ awareness of organic management is crucial for enhancing land productivity and maintaining soil fertility in Ngawi Regency.

A comprehensive understanding of rice straw (RS) and biochar (BC) addition affecting soil quality, enzyme activities, bacterial community structure and grain yield is crucial. The objective of this study was to examine the dynamics of the soil microbial community impacted by the application of rice straw and biochar, and to understand the relationship between the microbial communities, soil enzymes, nutrients and grain yield of paddies. We conducted a field experiment with organic amendments under the direct seeding of paddies. The bacterial community structure in the rhizosphere was characterized using high-throughput 16S rRNA sequencing. The results showed that RS amendment increased grain yields by 8.5 and 9.9% more than with BC and the control without organic amendment (CK), respectively (p < 0.05). The abundance of bacteria associated with nitrate reduction in RS was higher than that in BC and CK, which further showed the significance of the RS-treated soil bacteria in rice nutrient utilization. A cladogram plotted using linear discriminant analysis effect size showed that Proteobacteria (Alphaproteobacteria), Acidobacteria, Firmicutes, Verrucomicrobia and Epsilonbacteraeota in the RS-treated soil increased in comparison with CK. Pearson’s correlation analysis showed that enzymes activities (cellulase activity and protease activity), soil nutrition content (soil hydrolyzable nitrogen), and bacterial phyla (Nitrospinae) were positively correlated with grain yield, suggesting that the RS-treated soil improved enzyme activities, soil nutrition content, and bacterial abundance, which in turn increased grain yield. The results indicated that RS-treated bacterial communities combined with soil enzymatic activities strengthen the transformation of nutrients, suggesting that the interactions play an important role in enhancing the grain yield of paddy rice. These results provide new insights and a theoretical basis for studying the changes in soil microbial communities with the application of RS and BC in Northeastern China.
