Abstract Chisel plows with a chisel as working body, loosen the soil without mixing layers. The analysis of conducted research concludes that most widespread is cylindrical surface body - constant radius curvature. It theoretically established at curvature bit up to 0.1 m, on will move chaotically, while does not affect percentage wrapped plant debris. As increases, force inertia decreases, the...

Plant pathologists' traditional recommendations have been to clean-till fields. A few passes with the disk were good. Better yet, moldboard plow the residue under. Even better, burn the stubble, then plow it. Unfortunately, clean-tilling fields did not turn out to be a sustainable practice. Water and wind erosion claimed too much top soil and threatened to reduce the yield potential of our fiel...

suitable soil structure is important for crop growth. one of the main characteristics of soil structure is the size of soil aggregates. there are several ways of showing the stability of soil aggregates, among which the determination of the median weight diameter of soil aggregates is the most common method. in this paper, a method based on adaptive neuro fuzzy inference system (anfis) was used...

This study was devoted to verifying the effect of using three different coating materials on draft requirement chisel plow shares. Four types shares with same geometric dimensions (70 mm width, 0.26 rad as lift angle and 45° for cutting angel) were used.  One share kept without its standard iron a control, other coated copper, aluminum stainless steel. Experiments conducted an open air soilbin ...

Kucey and Schaalje, 1986; Reeves et al., 1993; Randall et al., 1997; Torbert et al., 2001). Tillage and N management systems can have a significant effect Many soil and water quality problems are associated on N use by corn (Zea mays L.) and nitrate (NO3–N) movement with conventional tillage, along with other problems that through the soil profile. Potential water quality and NO3–N loss probaff...
