“…As application of biochar to soils is considered to have many benefits for sustainable environmentally friendly agriculture, the issue also contains a case study from Thailand by Sriphirom et al (2020) evaluating biochar application combined with alternate wetting and drying water management in a rice field as an option for farmers to adopt to mitigate CH 4 emissions. Finally, this special issue on Soil C and N by LUMC includes a case study from Uganda, Africa conducted by Inubushi et al (2020) on the effect of long-term fertilizer management in NERICA cultivated uplands on the biochemical properties of soil.…”

“…In long-term rice-wheat experiments in Kyushu, Japan; Ludhiana, India; and Bhairahawa, Nepal, organic amendments affected soil parameters including microbial biomass (Tirol-Padre et al 2005. Even in Uganda, located in sub-Saharan Africa, fertilizer managements in the long-term experiment affected the biochemical and microbiological properties of the soil, including its microbial biomass, in NERICA (New Rice for Africa) cultivated upland (Inubushi et al 2020), where available P was another important factor. On the basis of these studies, organic manure has been recognized as essential for sustainably maintaining soil quality.…”

The 2030 Agenda was promulgated for the Sustainable Develop Goals (SDGs), which consist of 17 goals created to eradicate poverty and realize a more sustainable world. Among the goals, soil science can contribute significantly toward achieving zero hunger (#2), implementing climate action (#13), bettering life on land (#15), among others. Paddy fields are important sustainable agro-ecosystems for rice (Oryza sativa) production, and rice is the staple food for more than 2 billion people worldwide. Paddy rice is produced mainly in East, South, and Southeast Asia, in region with a monsoon climate. Paddy soils are unique, as they are mostly managed under waterlogged conditions during the rice-growing season. Nitrogen (N) is one of the most important nutrients for many crops, including rice. Some potential sustainable soil management methods are suggested to meet the SDGs, especially in paddy fields and wetlands in East, South, and Southeast Asia, based on current achievements, including N mineralization analysis, soil microbial analysis, and greenhouse gas measurements, to predict soil fertility and effective environmental management practices in the future. One such example of sustainable soil management practice is the amendment of silicate fertilizer produced from steel-making sludge that reduced methane emission from paddy fields (3%-50%) and increased the rice yield in Vietnam.

“…In long-term experiments, the dual application of mineral fertilizers and different organic materials was the most effective for soil biochemical processes (BÖHME et al, 2005;INUBUSHI et al, 2020;SIMON & CZAKO, 2014). The beneficial effect could be due to the long-term stimulative effect of the combined nutrient replenishment.…”

The Westsik’s long-term crop rotation experiment was set up in 1929 at the Nyíregyháza Experimental Station (NE Hungary) on a slightly acidic Arenosol. Besides fallow crop rotation (CR), effects of different organic amendments (lupine as green manure, lupine as main crop, straw manure, and farmyard manure (FYM) were studied with or without N or NPK-fertilizers. The crop rotation consisted of rye, potato, lupine, and oat with common vetch. The soil of potato plots was analysed in 2019 at the 90th anniversary of Westsik’s crop rotation experiment.The following chemical and microbiological soil parameters were determined: soil pH, available nutrient contents, organic carbon (OC) and nitrogen (ON) contents, microbial biomass carbon (MBC) and nitrogen (MBN), soil respiration, net nitrification, and activity of some soil enzymes.In the CRs, the soil pHH2O varied from acidic to weakly alkaline and it largely differed from pHKCl. The results showed a significant increase in the content of nitrate, available phosphorus and potassium in most of the fertilized plots. Applying straw, green manure, or FYM significantly increased the OC and ON contents. The total count of cultivable bacteria increased upon the application of the organic manures. Combined application of straw manure and N-fertilization heavily improved the abundance of the microscopic fungi.While all the applied organic manures significantly enhanced the MBC, the MBN increased only by the green manure amendment. Our results revealed higher soil respiration rate in the plots receiving straw or FYM than in the control. Both green manure and FYM elevated the net nitrification rate. Phosphatase, saccharase, urease, and dehydrogenase enzymes showed a hesitating response to the manure application in the different CRs.The soil respiration and dehydrogenase activity correlated to most of the measured chemical parameters. Among microbiological properties, the MBC and MBN, as well as dehydrogenase and other enzyme activities displayed a positive correlation. Results proved the need for the exogenous application of organic matter in the form of organic manures to enhance the nutritional status and health of the soil.
