Subsoils are widely used on tillage and combination machines. The tiller of the combined machine for preparing soil sowing melons gourds carries out strip loosening subsoil layers. study aims to theoretically determine traction resistance a deepener gourds. uses basic provisions mathematics, theoretical mechanics, agricultural mechanics. In studies, it is assumed that destruction under influenc...

The traditional fertilizer application methods have serious problems of environmental pollution and soil degradation due to low utilization rates in the Huang–Huai–Hai Plain China. In this study, conservation tillage strip-hole layered fertilization method was proposed a precision subsoiler designed. To meet requirements for deep application, theoretical analysis parameter calculations were fir...

the aim of this study was to investigate the effect of tillage methods to obtain suitable seedbed for monogerm seed. therefore, a split plot experiment based on a randomized complete block design (rcbd) with three replicatians was conducted at darab station of fars province. the main plot was seedbed prepration at two levels including fall and spring season. subplot included 1) moldboard plow a...

Water erosion and runoff can be severe due to poor infiltration through frozen soil in the dryland wheat (Triticum aestivum L.) production region of the inland Pacific Northwest (PNW), USA. For more than 70 years, farmers and researchers have used various methods of subsoiling to reduce runoff and erosion and to improve infiltration and soil moisture storage. The practice and equipment have evo...

for designing tillage implements it would be better to estimate soil forces exerted to the implements. many researches showed that numerical method of discrete element method (dem) is the cheapest and fastest technique for modeling granular material such as soil and especially sandy soil. in this study, paraplow and bentleg tines performance was compared with conventional tine using experimenta...
