The ability of tillage implements to maintain surface residue coverage is largely dependent on the implement’s main active component. Two categories of tillage implements were compared to determine their ability to maintain grain sorghum (non–fragile) surface residue coverage when operating at two different tillage depths for fall and spring tillage. Chisel–type implements were found to bury su...

To study Assessing the impact of tillage practices on soil carbon losses dependents it is necessary to describe the temporal variability of soil CO2 emission after tillage. It has been argued that large amounts of CO2 emitted after tillage may serve as an indicator for longer-term changes in soil carbon stocks. Here we present a two-step function model based on soil temperature and soil moistur...

ABSTRACT The population density of the reniform nematode, Rotylenchulus reniformis, was monitored at depths of 0 to 30, 30 to 60, 60 to 90, and 90 to 120 cm in a tillage and crop sequence trial in south Texas in 2000 and 2001. Main plots were subjected to three different tillage systems: conventional tillage (moldboard plowing and disking), ridge tillage, and no-tillage. Subplots were planted w...

Conservation tillage has been promoted as a solution to counteract constraints caused by intensive agriculture. In this work the effects of two conservation tillage systems, reduced tillage (RT) and no-tillage (NT) were compared to the traditional tillage (TT) in a long(15 years, RT) and short-term experiment (3 years, NT). Both experiments were carried out under semi-arid, rainfed agriculture ...

Zones of farming with arid climate require scientific justification and competent approach in the field tillage. The main objectives developing approaches to mechanical tillage soil-protective technologies are reduce erosion processes, accumulate retain moisture, create favorable conditions for growth cultivated plants root zone. Reducing number soil treatments during growing season contributes...

Compared to conventional tillage (CT) system (e.g. moldboard plowing (Moldboard-CT) and chisel (Chisel-CT)) adoption rate of conservation systems no-till (NT) strip-till (ST)) in surface- irrigated farms is considerably low. A three-year field study was conducted evaluate corn (Zea mays L) productivity four ranging intensity soil disturbance (i.e. Moldboard-CT, Chisel-CT, ST, NT) a furrow-irrig...

This study was designed to investigate the effects of different tillage systems on some parameters such as soil salinity (pH, EC, SAR), soil density and nutrients in a nested experimental design with three treatments (no tillage, reduced tillage and conventional tillage) and three replications. Chenaran city fields were selected as the case study areas. Result of the statistical analysis indica...
