Simulation modeling is widely used to assess water contamination risk associated with pesticide use and for evaluating effectiveness of agricultural conservation practices. Currently the Agricultural Policy/Environmental eXtender (APEX) model is being used for this purpose in the USDA Conservation Effects Assessment Project (CEAP) Cropland National Assessment. In support of the CEAP modeling ef...

The sugarbeet industry in the Pacific Northwest is interested in strip tillage (ST) primarily due to the potential savings in tillage costs. This study was conducted to evaluate the use of ST in the Pacific Northwest compared to conventional tillage (CT) practices and to evaluate N requirements of sugarbeet under ST and CT. The effect of tillage method (ST, moldboard plow [MP] system, and chise...

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...

Growth and yield of winter oilseed rape under strip-tillage compared to conventional tillage | David Be?ka, Lucie Be?ková, Perla Kuchtová, Pavel Cihlá?, Kate?ina Pazder?, Vlastimil Mikšík, Jan Vašák Agricultural Journals

A two year (2010-2012) study was conducted to assess the effects of different agronomic management practices on the emissions of CO2 from a field of non-irrigated wheat planted on China's Loess Plateau. Management practices included four tillage methods i.e. T1: (chisel plow tillage), T2: (zero-tillage), T3: (rotary tillage) and T4: (mold board plow tillage), 2 mulch levels i.e., M0 (no corn re...

Conservation tillage is an effective sustainable production system for vegetables. No-till planters and transplanters and strip-till cultivation equipment are presently available for most vegetables. Lack of weed management tools (herbicides, cultivators, etc.) continues to be the cultural practice that limits adaptability of some vegetables to conservation tillage systems. Nitrogen management ...

ABSTRACT Conservation agriculture principles applied to peanut can reduce soil erosion and production costs when cultivated in rotation with sugarcane. Still, the problem compaction is leading cause of skepticism about efficacy this practice. This research aimed study effect three management strategies compared conventional for cv. IAC-OL3, sugarcane using MEIOSI (method intercropping occurring...

Introduction Conservation tillage has been one of the most rapidly adopted agricultural practices of the past 15 years (CTIC, 1983). The primary impetus for conservation tillage has been decreased soil erosion; fuel, labor, and machinery costs; and increased soil water storage and yields (USDA, 1975). Conservation tillage may be broad­ ly defined as tillage practices that reduce soil and water ...

ern Tennessee (Stevens et al., 1992; Bradley, 1993; Triplett et al., 1996), conservation tillage practiced on silty clay Yield reductions from no-tillage cotton (Gossypium hirsutum L.) soils in northern Alabama resulted in 8 to 15% yield jeopardized adoption of conservation systems in the Tennessee Valley region of north Alabama in the early 1990s. We conducted a study from reductions compared ...

Based on the test results, a section of working bodies was selected for strip tillage, theheight, length soil disks were determined experimentally. As well as result acceptable tillage is combination bodies, consisting one cutting paws with soilproviding high rates crumbling quality cleansing them stubble and roots.
