introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...

Considering the planting mode and agronomics requirements of existing facilities, high-power rototilling ridge hoisting lamination machine is difficult to operate in greenhouse facility, small hanging rotary raiser has technical problems such as insufficient horsepower. This paper designs tillage ridging film - covering machine. The realizes a single operation process complete tillage, ridging,...

Diversified crop rotation may improve production efficiency, reduce fertilizer nitrogen (N) requirements for corn (Zea mays L.), and increase soil carbon (C) storage. Objectives were to determine effect of rotation and fertilizer N on soil C sequestration and N use. An experiment was started in 1990 on a Barnes clay loam (U.S. soil taxonomy: fine-loamy, mixed, superactive, frigid Calcic Hapludo...

Tillage erosion is a potential contributor to the total soil erosion occurring within cultivated fields. No study has been carried out on tillage erosion associated with cereal-based production systems, which are the predominant form of crop production in the Canadian Prairies. Previous tillage translocation studies have focused on primary tillage implements (i.e. mouldboard and chisel ploughs)...

The article presents the results of research on development technology for comb cultivation industrial crops with targeted and uniform moistening root system plants. Innovative ridge tillage soil simultaneous sowing seeds laying a drip irrigation hose ridge, accumulation moisture is excluded, which leads to pollination soil, destruction structure formation crust, this contributes production fri...

Large nitrogen (N) losses during fertilization in agricultural production may result energy wastage, soil and water contamination, potentially influence crop development. Thus, with the help of a 15N-labeled tracer, we carried out field monitoring analysis NH3 emissions long-term (9-year) conservation tillage agroecosystem Mollisols northeast China, order to determine whether no-tillage regime ...

A GLEAMS (ver. 2.10) model was calibrated and validated using three years (1990–1992) of field–measured data to simulate tillage effects on nitrate–nitrogen (NO3–N) and herbicide losses with subsurface drain “tile” water beneath a continuous corn production system. The model was calibrated for chisel plow systems using 1991 field data and was validated against field data of two years (1990 and ...

During decades, in semiarid rainfed Aragon, intensive soil tillage and low crop residue input have led to the loss of soil structure and soil degradation. Conservation tillage and cropping intensification can improve soil structure in these areas. The objective of this study was to determine the influence of three different tillage systems (traditional tillage, reduced tillage and no-tillage) u...
