The excessive application of manure on cropland areas can cause nutrients to accumulate near the soil surface and increase nutrient transport by overland flow. Inverting soils with high surface nutrient content could reduce runoff nutrient transport. This study was conducted to measure the effects of moldboard plowing on the redistribution of nutrients within the soil profile and nutrient trans...

To carry out effective plant protection measures, it is necessary to take into account all the factors affecting quality of crop. The aim our research was study degree development leaf diseases winter wheat and rate infestation crops, depending on tillage method. studies were carried in 2019-2020 at experimental plots “Kuban educational farm” Krasnodar. For research, four with Steppe variety so...

in this research was designed a differential lock control system. the system was test and evaluated after fabrication and its accuracy and precision was determined. a field experiment with three replications was conducted to investigate the effect of gear ratio, the method of tractor movement during plowing and differential position on drive wheel slippage and fuel consumption of mf399 tractor ...

rotation is also more effective in preventing deep leaching of nitrate N than continuous corn (Katupitiya et al., Reduced tillage, including no-till, and crop rotation are common 1997; Varvel and Peterson, 1990). Reduced stress from practices for corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] production in the Midwest. Benefits of no-till vary with latitude pests may be one of the reas...

Extreme meteorological phenomena resulting from climate change caused by anthropogenic emissions of greenhouse gases (GHG) require the implementation CO2 mitigation practices various industries, including agriculture. Owing to varying soil, climatic, and agrotechnical characteristics, they may have different efficiencies in mitigating soil emissions. The aim this study was evaluate impact three...

Producers are frequently most interested in economic comparisons of various cropping systems. We compared continuous corn (Zea mays L.) and continuous soybean [Glycine max (L.) Merr.] with 2-, 3-, and 5-year rotations, the latter two including wheat (Triticum aestivum L.) and alfalfa (Medicago sativa L.), using either chisel plow or no-tillage practices. Crop yield and returns to land and manag...

Differential lock is a means of improving tractor performance. This system causes the revolution of the axles to become equal. It, improves traction, decreases abrasion of drive tires, improves fuel consumption, and increases tractor work rate. Despite advantages of the system, differential lock has not been optimized in Iran. Thus, a semi-automatic differential lock system for MF-285 tractor w...
