To study Assessing the impact of tillage practices on soil carbon losses dependents it is necessary to describe the temporal variability of soil CO2 emission after tillage. It has been argued that large amounts of CO2 emitted after tillage may serve as an indicator for longer-term changes in soil carbon stocks. Here we present a two-step function model based on soil temperature and soil moistur...

Existing plows do not provide high-quality tillage between rows of orchards and vineyards. The purpose the study is to develop justify parameters plow for cultivating soil gardens tractors class 0.9 kN. A design scheme a single-body smooth, rowless plowing garden aisles has been developed. proposed consists movable fixed frame, disc knife, screw body with hostage. research uses laws agricultura...

We studied the drag and lift forces acting on an inclined plate while it is dragged on the surface of a granular media, both in experiment and in numerical simulation. In particular, we investigated the influence of the horizontal velocity of the plate and its angle of attack. We show that a steady wedge of grains is moved in front of the plow and that the lift and drag forces are proportional ...

The distribution of soil particles and planting tube space position affects reversal cultivated land and fertilization seeder seeding performance. Through the establishment of ratary tiller system coordinate system; Firstly giving the analysis of soil grain not heel cover shell collision and the first meeting with cover shell collisions motion situation, through Matlab found the first meeting w...

the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...

Spring barley is a multipurpose crop. High-quality and valuable grain with high protein content, which formed at temperatures in the phase of filling. But droughty conditions are unfavorable for entire growing season plants. Therefore, cultivation spring an arid climate requires competent approach based on rational combination agrotechnical methods, among special place given to main tillage. Th...

the chisel plow is one of the tillage implements utilized to carry out conservation tillage practices; therefore, it is valuable to pay more attention on the force requirement of this implement. to achieve this goal, a theoretical model was developed to calculate draft, specific draft, and drawbar power of a chisel plow. then, results obtained from the developed model were compared with the rep...

Airborne sediment fluxes were measured in southern Tunisia on two experimental plots tilled with a moldboard and tiller plough, respectively, during five wind erosion events of different intensities. The sampled both using mast equipped seven sand traps positioned between ≈10 120 cm height. windblown the 0–100 layer about eight times higher plot plough compared to due efficiencies trapping salt...
