The potential of reduced tillage in Flanders
… decline in SOM and N losses. Conservation tillage (CsT) agriculture was first introduced on a large scale on fields with mainly cereals, soybean and sunflower in the USA, Latin America and Australia as a very effective measure to reduce erosion and store water into the soil (Arshad, 1999; …

Generalist predators in reduced-tillage corn: predation on armyworm, habitat preferences, and a method to estimate absolute densities
… where generalist predator populations were reduced, through the use of pitfall traps and exclusion arenas, than in the control where predator populations were unaltered. The differences in the proportion of damaged plants and the degree of damage between the predator removal treatment and …

The Influence of Weeds Associated With Reduced-Tillage Corn on a Black Cutworm Parasitoid, Meteorus Rubens (Nees Von Esenbeck), and Computer Simulation of The Consequences for Black Cutworm Damage
The impact of nectar-feeding at flowering weeds by Meteorus rubens on black cutworm damage to seedling corn was investigated through a combination of experimental research and computer simulation. In the laboratory, female M. rubens provided with flowering weeds lived on average 7.6 days, more than …

Inheritance of Cold Temperature Emergence in Soybeans and Its Relationship to Field Emergence and Seed Yield of Early Planted Soybeans (Heritability, Genetic, Vigor)
Increasing use of reduced-tillage techniques, earlier planting, and late cold snaps can result in the exposure of emerging soybeans to suboptimal soil temperatures. Such exposure can result in decreased emergence, reduced seedling vigor, increased incidence of disease, and lowered yields. Soybean …

An Examination of Neglected Issues in Illinois No-Till Adoption Research and the Educational Implications Thereof
… moldboard plow based farming technology to reduced tillage systems, the ultimate of which is the no-till system--placing the seeds in very narrow slots without disturbing last year's crop residue."

Value of Cultural Practices for Improving Nitrogen Management in Corn
… included time of N application, degree of tillage, and varying levels of corn rootworm (Diabrotica spp.) larval damage. Results showed that management practices such as reduced tillage and/or fall or winter applied N can have a greater N requirement compared with more conventional …

Minimizing the continuous maize penalty through intense management
… maize penalty through the use of stover removal, reduced tillage, and an addition/omission design of advanced crop inputs. Nitrogen (N) fertilizer, non-N fertilizer, hybrid trait, plant density, and fungicide were five management inputs used to create an addition/omission design. Additionally, …

Integrating cover crops into crop rotations in upstate Missouri
… emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best management practices for conservation, soil health could be improved, …

A fresh soil health perspective: Soil health dynamics and improved measurement techniques
… of conservation agriculture practices such as reduced tillage and cover crops may require better understanding of the effect of these practices on soil health. The overall objective of this study was to quantify soil health dynamics due to conservation agriculture practices and address …

Biophysical economic analysis of nutrient and sediment management practices in the Mississippi Alluvial Valley
… This dissertation looked at nutrient and tillage management practices that could help farmers address future total maximum daily loads (TMDLs) for the Cabin-Teele sub-watershed, within the lower Mississippi River Basin. The dissertation had two objectives. The first objective was to …

Drivers of smallholder adoption and the intensity of conservation agriculture in the Masvingo District of Zimbabwe
… Although most smallholders implemented the reduced tillage component of CA, only a few implemented all three components. Farm size and experience with CA technology impacted positively on the current use of CA. Distance from town (market) and ownership of an ox-drawn plough reduced the …

Simulation and assessment of highly altered hydrologic system responses to anthropogenic and natural stressors at the watershed scale
… 2013). Examples of WMPs are riparian buffers, reduced tillage practice, filter strips, cover crops and crop rotation. Hence, WMPs may be viewed as anthropogenic stressors strategically implemented to reduce the impacts of farming activities on the ecosystem. The implementation of these …

Stover, tillage, and nitrogen management in continuous corn for grain, ethanol, and soil carbon
… heavy-textured, poorly-drained soils in several tillage systems in environments where soil temperature is often a limiting factor on crop growth. This research indicates corn stover removal in continuous corn cropping (CC) systems improves agronomic performance, but decreases soil C in as little …

Implementation of Sustainable Management Practices at Two California Central Coast Vineyards and Their Effects on Soil Fertility
… green waste compost (Forest Blend), and reduced tillage on soil fertility were investigated in San Luis Obispo, California on a clay and sandy loam soil. Between the fall 2007 and spring 2008, which had a low precipitation amount (13.3 & 15.6 inches), there was a significant difference (P …

Analysis of best management practices implementation on water quality using the Soil and Water Assessment Tool (SWAT)
… were evaluated. These BMPs include residue reduced tillage operations, vegetative filter strips, and wetlands. These BMPs were tested on a yearly (1980-2009) basis in order to determine their statistical significance and the associated pollutant reduction potential. SWAT is able to calibrate …

The effect of reduced cultivation on selected soil fauna
… the rate of soil erosion. The introduction of reduced tillage systems has led to savings in both labour and energy, and to increased soil conservation. Changes in cultivation regimes bring about changes in soil characteristics which will in turn affect the populations of soil fauna. A survey of …
