Abstract

The effect of organic and inorganic fertilizers, as well as their combinations, on soil fertility and productivity is studied on the soddy podzolic light loamy soils in the stationary field experiment. The highest efficiency of combined application of organic (80 t/ha of peat–manure compost) and inorganic (NPK) fertilizers is determined in a six-field fodder crop rotation. The positive effect of the organic and organic–inorganic fertilizer system on the soil’s organic matter content, a decrease in exchange and hydrolytic acidity, and an increase in the mobile phosphorus content is found. A decrease in exchangeable potassium in the soil is observed due to its high removal by crops. It is determined that the above fertilizer systems contributed not only to an increase in the yield of crops in rotation but also their quality. The content of starch and vitamin C increased in potato tubers and crude protein increased in annual and perennial grasses.

在欧洲北部，连续施用有机和无机肥料对肥沃土壤中肥沃的土壤肥力和作物生产力的影响

摘要

在固定的田间试验中，研究了湿润的坡地浅壤土上有机和无机肥料及其组合对土壤肥力和生产力的影响。在六田饲料作物轮作中，有机肥（80吨/公顷的泥炭肥料堆肥）和无机肥（NPK）的联合施用效率最高。发现有机和有机无机肥料体系对土壤有机质的积极影响，交换和水解酸度的降低，以及活动性磷含量的提高。观察到土壤中可交换钾的减少，这是由于农作物对钾的去除率很高。已确定上述肥料系统不仅有助于轮作作物的产量增加，而且有助于其品质。
