“…Ecologically, rice rotation with legumes could be another option in this region, but this practice could not be widely accepted by local farmers due to the small contribution of legumes to the economics of the region. To further enhance the socioeconomic as well as ecological (see below) benefits of rice production, some green manure crops should be intermittently grown after a few cycles of PR practice [43,44].…”

Cropping systems greatly impact the productivity and resilience of agricultural ecosystems. However, we often lack an understanding of the quantitative interactions among social, economic and ecological components in each of the systems, especially with regard to crop rotation. Current production systems cannot guarantee both high profits in the short term and social and ecological benefits in the long term. This study combined statistic and economic models to evaluate the comprehensive effects of cropping systems on rice production using data collected from experimental fields between 2017 and 2018. The results showed that increasing agricultural diversity through rotations, particularly potato–rice rotation (PR), significantly increased the social, economic and ecological benefits of rice production. Yields, profits, profit margins, weighted dimensionless values of soil chemical and physical (SCP) and heavy metal (SHM) traits, benefits and externalities generated by PR and other rotations were generally higher than successive rice cropping. This suggests that agricultural diversity through rotations, particularly PR rotation, is worth implementing due to its overall benefits generated in rice production. However, due to various nutrient residues from preceding crops, fertilizer application should be rationalized to improve the resource and investment efficiency. Furthermore, we internalized the externalities (hidden ecological and social benefits/costs) generated by each of the rotation systems and proposed ways of incenting farmers to adopt crop rotation approaches for sustainable rice production.

“…Kang et al. (2020) have found that applying pig ( Sus scrofa domesticus ) manure (PM) could significantly improve nutrient supply. Pig manure liquid treatment had positive effects on the improvement of rice ( Oryza sativa L.) yield, soil physicochemical properties, and microbial biomass N content.…”

Organic materials incorporation and nitrogen utilization are both important measures to enhance soil fertility and crop productivity. To evaluate the effect of different organic materials on soil N utilization and crop yield, three kinds of organic materials, including straw (ST), pig manure (PM), and biogas residue (BR), were incorporated into the soil with equal N in the wheat (Triticum aestivum L.)-maize (Zea mays L.) cropping system with chemical fertilizers (CFs) as a control in Wuqiao County in the North China Plain. The contents of soil N, nitrate N, ammonium N, N use efficiency, N partial productivity (NPFP), N uptake efficiency (NUPE), and N harvest index (NHI) were measured and calculated. The results of 2-yr field trials suggested that, compared with CF, soil total N (TN) content of ST, PM, and BR treatment increased by 3.04, 8.99, and 9.10%, respectively. An even larger increase was found in nitrate N, which was 25.87, 44.67, and 44.93% in ST, PM, and BR, respectively. For N utilization, PM significantly increased NPFP, NUPE, and NHI by 4.01, 5.86, and 3.04%, respectively, meanwhile decreasing soil N dependency rate by 4.64%; BR improved NUPE by 5.15%, while ST showed little improvement in the utilization of soil N. Overall, organic materials promoted soil N maintenance and increased N utilization.Among the kinds of organic material amendment in the study, PM had a better performance in improving soil N utilization and crop yield than BR and crop ST return in field experiments. INTRODUCTIONIn crop and soil systems, N has been suggested to be a factor in crop growth and yielding ability by participating in plant genetic metabolism (material synthesis and signal transduc-

This study was conducted to investigate corn growth and soil fertility after soil amendment application of three types in an upland field in South Korea. Each of the barley straw biochar (BSB, applied at 1,000 kg 10a -1 ), animal carcass biochar (ACB, applied at 1,000 kg 10a -1 ) along with compost (applied at 2,000 kg 10a -1 ), and bottom ash (BA, applied at 1,000 kg 10a -1 ); the Control area was only treated compost. The corn grain yield was improved when grown under BSB, ACB, and BA with compost. Overall, biochar application had more effect on the productivity of biomass and corn yield, and showed significant results in corn cultivation. In particular, the corn grain yield was the highest under BSB treatment was over 22%, 11%, and 7% higher than those grown under Control, ACB, and BA treatments, respectively. Soil chemical properties after soil amendment addition were improved. In particular, soil pH and CEC related to crop nutrient availability were significantly increased in BSB, ACB, and BA areas compared to those in Control area. Therefore, these results indicate that corn productivity, when cultivated in soil conditions such as those in an upland field in South Korea, can be increased by application of soil amendments including BSB, ACB, and BA with compost.
