大概不是土壤的所有性能和植物营养条件都与腐殖质有关系。然而,土壤有机物质对农作物产量的影响仍然是讨论的主题。有一种意见认为,腐殖质不能认为是土壤生产力因素之一,而现存的腐殖质与产量之间的关系是产量的结果。土壤生产力与腐殖质含量的相关性,在田间试验和盆栽试验中对它进行了研究。田间试验研究用材料是草原土壤,灌溉的普通黑钙土(古比雪夫州,宾金秋克)、灌溉
Probably not all soil properties and plant nutrient conditions are related to humus. However, the impact of soil organic matter on crop yields remains the subject of discussion. There is a view that humus can not be considered as one of the factors of soil productivity, and the relationship between the existing humus and yield is the result of production. Soil productivity and humus content of the correlation in field experiments and pot experiments it was studied. Materials used in field trials are grassland soil, plain chernozem (Gubyshev State, Binjinqiuke) irrigated
