performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...

This study was devoted to verifying the performance of various configurations a winged chisel plough (WCP) in soil bin. The new tool assessed at three wing depths (5, 10 and 15 cm), bend angles (10, 20 30 °), rake (7.5, 22.5 °) with replications using completely randomised design constant depth speed cm 1 m·s–1, respectively. draught vertical forces, disturbed upheaved areas plus efficiency loo...

re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

conclusions based on the results of this study there is a risk of infection with soil transmitted helminthes among children of kermanshah, iran. results out of 192 soil samples, soil of play areas from four regions was contaminated with geohelminth eggs. the rate of soil contamination with trichuris spp. eggs was 3.12% while this was 2.1% for hookworm eggs, yet no ascaris eggs were found in the...

in this work x-ray fluorescence (xrf) technique was used to evaluate the soil pollution withheavy metals for twenty four surface soil samples (0–10 cm in depth) from various locations to cover theindustrial area in omdurman city, sudan. concentrations of 10 elements cr, ni, cu, zn, zr, pb, rb, co, cd andas were determined. it was found that cr, cu and cd concentrations for almost all studied si...

The aim of this paper was to investigate the recreational impacts on some soil properties (sand, silt, clay pH, electrical conductivity, organic carbon, bulk density, fine soil weight, compaction and saturation capacity), and litter (unit weight-mass, organic matter content (%) and organic matter mass) properties in a picnic area by comparing an undisturbed area in Istanbul Belgrad Forest-Turke...
