Background Weeds have high spatial variability and show clustering behavior, with heterogeneity in scales that can be evaluated through multifractal analysis. Objective The objective of this study was to evaluate the weeds using analysis a no-till area. Methods Sampling conducted at 1,015 sampling points an experimental plot regular grid 5 × m (2.38 ha) no tillage. area cultivated triticale (Tr...

Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

No-till acreage has increased in recent years, but many farmers alternate no-till with other tillage practices, limiting public and private benefits from sustained no-till adoption. Revealed preference data are used in an ordered logit regression analysis to determine the effect of soil characteristics, climate, regions, farm characteristics, and producer demographics on producers’ choices to u...

Reproduction of the soybean cyst nematode (SCN), Heterodera glycines Ichinohe, on soybean, Glycine max (L.) Merr., has been compared in conventional till and no-till field plots. Rate of SCN population density increase during the growing season was lower in no-till than in conventional till plots (3,5), or the number of SCN at harvest was lower in no-till than in conventional till plots (6). In...

Accurately determining productive water use ( i.e. , transpiration T, component of evapotranspiration ET) is crucial to improve ecosystem efficiency (EWUE) and develop water-saving management practices. High frequency (10 Hz) eddy covariance data for the 2016–2017 growing season (November 2016 – May 2017) conventional till (CT) no-till (NT) canola Brassica napus L.) fields were analyzed partiti...

Many farmers in the steeply sloped Palouse region of eastern Washington and northern Idaho practice no-till (NT) farming. Soil quality and water intake parameters were assessed in standing wheat (Triticum aestivum L.) stubble along summit, side, and toe-slope positions in a 2-yr study at three paired-farm sites using traditional tillage (TT) vs. NT management. Paired sites had similar south-fac...

No-till cropping can increase soil C stocks and aggregation but patterns of long-term changes in N2O emissions, soil N availability, and crop yields still need to be resolved. We measured soil C accumulation, aggregation, soil water, N2O emissions, soil inorganic N, and crop yields in till and no-till corn-soybean-wheat rotations between 1989 and 2002 in southwestern Michigan and investigated w...
