Recently tillage manufacturers have been promoting vertical tillage systems claiming that their use can overcome production limitations associated with no-till while maintaining sufficient residue cover to provide erosion protection. Vertical tillage refers to systems where soil disturbance is confined to soil movement mostly in the upward direction and/or confined to a slot or strip where the ...

the introduction of canola (oilseed rape; brassica napus l.) as a new source of vegetable oil production in iran prompts evaluation of the performance of this crop under different tillage systems. a field experiment was conducted to determine the impact of depth and intensity of tillage on soil physical properties, crop establishment and yield of irrigated winter canola in a loam soil (typic ha...

Spain is one of the countries with the highest greenhouse gas (GHG) emissions within the EU-27. Consequently, mitigation strategies need to be reported and quantified to accomplish the goals and requirements of the Kyoto Protocol. In this study, a first estimation of the carbon (C) mitigation potential of tillage reduction in Mediterranean rainfed Spain is presented. Results from eight studies ...

Agricultural productivity relies on a wide range of ecosystem services provided by the soil biota. Plowing is a fundamental component of conventional farming, but long-term detrimental effects such as soil erosion and loss of soil organic matter have been recognized. Moving towards more sustainable management practices such as reduced tillage or crop residue retention can reduce these detriment...

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...

dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...

A field study was conducted to assess the effects of soil tillage practices and straw management on soil CO2, and yield-scaled CO2 emissions in a rain-fed summer corn field on the Loess Plateau. Tillage treatments consisted of sub-soiling tillage (CP), no tillage (NT) and moldboard plow tillage (CT). Wheat straw was removed from half of the CP, NT and CT plots after harvest, allowing us to test...

The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...

the conservation system is one of the proper methods avoiding the loss of nutrients, soil erosion, and reduce production costs. this research was examined for studying the influences of tillage systems on the three cotton cultivars at karkandeh and hashm-abad stations in gorgan. the experiments were conducted in a randomized completely block design as split plot with three replications with fiv...

Soil loss through wind and water erosion is an ongoing problem in semiarid regions. A thin layer of top soil loss over a hectare of cropland could be corresponding to tons of productive soil loss per hectare. The objectives of this study were to evaluate the influence of beef feedlot manure, tillage and legume grass mixtures on changes in soil quality and nutrient components. The study was init...
