Investigating microbial metabolic characteristics and soil organic carbon (SOC) within aggregates and their relationships under conservation tillage may be useful in revealing the mechanism of SOC sequestration in conservation tillage systems. However, limited studies have been conducted to investigate the relationship between SOC and microbial metabolic characteristics within aggregate fractio...

to evaluate the effect of combined use of different soil tillage methods and weed control on cotton yield, a split plot experiment based on randomized complete block design was conducted at the city of boshruyeh in 2012. experiment factors were tillage method as main-plots with three levels, including conventional tillage, no-till system and minimum tillage; and different methods of weed contro...

Effects of land-use management on agricultural sustainability and greenhouse gas emissions are major issues for researchers, regional councils and farmers in New Zealand. This study was undertaken to investigate the environmental impact of land-use management on field-CO2 emissions in Ohakea silt loam soil (Typic andoaqualf) that had been converted from permanent pasture to forage cropping for ...

Conservation tillage mitigates soil loss in cropland because plant residues help protect the soil, but effects on pesticide movement in surface runoff are not as straightforward. Effects of soil disturbance on surface runoff loss of chlorimuron and alachlor were evaluated utilizing runoff trays. Soil in the trays was either disturbed (tilled) and kept bare or was not tilled, and existing decomp...

A 2-year field study was conducted in the southern High Plains region of Texas to evaluate the effect of tillage system and cotton planting date window on seasonal abundance and activity patterns of predacious ground beetles. The experiment was deployed in a split-plot randomized block design with tillage as the main-plot factor and planting date as the subplot factor. There were two levels for...

The grape berry moth, Paralobesia viteana (Clemens), is a key pest of vineyards in eastern North America that overwinters as pupae in leaf litter on the vineyard floor. This presents an opportunity for tillage to disturb and bury the pupae, providing a potential nonchemical approach to control of this pest. Using a Lilleston-style rotary cultivator, we determined the distribution of pupae withi...

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...

In this study, a fixed-site field experiment was conducted to study the influence of different combinations of tillage and straw incorporation management on carbon storage in different-sized soil aggregates and on crop yield after three years of rice-wheat rotation. Compared to conventional tillage, the percentages of >2 mm macroaggregates and water-stable macroaggregates in rice-wheat double-c...
