The comparative assessment of the straw-litter compost (20 t/ha), ammonium nitrate (30 kg/ha N) and micro-fertilizer Azosol 36 Extra effect on soybean productivity and soil fertility in the southwestern part of the Chernozem region was carried out. Three years research found that using compost led to the positive balance of soil humus and macronutrients, increased yield and protein harvesting. The highest value of the soil organic matter net-balance was observed under using compost with ammonium nitrate – 0,52-0,68 %. In addition to this variant, the increase in easily hydrolyzed nitrogen in the soil was due to the combined use of mineral fertilizers – from 3.3 to 8.2 mg/kg. The transfer by grouping to a higher supply class in terms of both mobile phosphorus (163-196 mg/kg) and exchangeable potassium (125-168 mg/kg) was associated with the action of compost, which contributed to increasing the element content by 36-47 mg/kg and 5,4-43 mg/kg, respectively. It was likely that the productivity of the early-ripening soybean variety Lancetnaya was due to the nitrogen assimilation mainly from mineral fertilizers, while the mid-ripening variety Belgorodskaya 48 was more responsive to the compost using. The complex application of organic and mineral fertilizers for soybeans provided the highest yield regardless of the soybean variety (3 t/ha) and the positive dynamics of typical chernozem indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
