The article proposes a method for calculating the traction resistance of universal combined working body, consisting rack with chisel, loosening and flat-cutting paws. paws can have both straight profile curved in various combinations.

This paper explains the microcontroller based fuzzy controller for an agricultural robot which can be used to plough the field, seeding and soil moisture sensing. By using the agricultural robots in field which can be used to reduce manpower and can be operated using remote controls from a distant place. In this paper , an agricultural robot is designed with an internet based remote control by ...

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 ...

The presence of deep-burrowing earthworms can affect soil structure and in®ltration, therefore in ̄uencing agricultural productivity. We investigated the effects of deep-burrowing earthworm species on soil structure at the surface of chisel-plowed or ridge-tilled cropping systems in Pike County, OH, planted to corn (Zea mays L.). Earthworm populations were experimentally manipulated in ®eld encl...

Soil erosion from agricultural lands can be reduced by adoption of conservation management practices. The objectives of this study were to investigate the effectiveness and cost-benefit of conservation management practices on sediment reduction under a corn–soybean rotation. The experimental site was 6.4 ha (15.8 ac) and located within the Four Mile Creek watershed in eastern Iowa. Management p...

Long-term assessment of NO3-N leaching losses to subsurface drainage "tile" water from different tillage systems and N application rates can help mitigate the environmental concerns of production agriculture. A three-phase field study was conducted to investigate the impact of two tillage systems (chisel vs. no-till) and different N application management systems on flow-weighted NO3-N concentr...

This paper presents the interaction system within mechanical soil processing process, consisting of two large elements, metal tool and soil. Due to main forces acting on chisel knives—friction impact with sandy soil—the wear these knives was determined. To determine wear, a stand used which allowed testing chisel-type in laboratory conditions by changing their functional parameters: working dep...
