in recent years, there has been increased concern over pollution of groundwater by NOj-, yet little is known about microbial N transformations below the crop rooting zone. This study investigated the importance of microbial denitrification below the crop rooting zone of conventional and no-till corn plots. The soil was a well-drained Matapeake silt loam located in the Atlantic Coastal Plain. Pl...

A study was carried out to evaluate the impact of various land use systems on physiochemical characteristics soil Krishna District, Andhra Pradesh. The samples were collected from (normally cultivated land, plantation, forest, fruit and vegetable) at two different depths (0-15 cm 15-30 cm) analysed Soil Science - Water Conservation Laboratory Rajiv Gandhi South Campus, Banaras Hindu University,...

The aim of the study was to identify trends and dynamics changes in chemical biochemical properties soil induced by rotational grazing farmed deer. Soils pH content mineral nitrogen forms, total nitrogen, organic carbon were determined activity three enzymes. monitored soils slightly acidic neutral, with 1 mol KCldm−3 ranging from 6.37 7.03. contents carbon, range 9.42–19.37 gkg−1 1.13–2.24 gkg...

Soil organic matter (SOM) is a complex mixture of multiple fractions soil C (SOC) that can be influenced by management decisions. This study evaluate the effects tillage (moldboard plow [MP] and no-tillage [NT]) commercial fertilizer as limestone ammonium nitrate (28–0–0) at three rates (0 [0-N], 100 [100-N], 200 [200-N] kg N ha–1) on SOC, total (STN), SOM (total particulate matter-C [POM-C] mi...

soil productivity and plant growth are usually affected by biological activities of earthworms. the objective of this study was a comparative evaluation of earthworm abundances in 20-year-old plantations of alder, oak, maple and cypress with the adjacent natural mixed broad-leaved deciduous forest in the caspian region of iran. in this research one sample plot, each 1 ha; was selected in every ...

Reducing tillage and growing cover crops, widely recommended practices for boosting soil health, have major impacts on soil communities. Surprisingly little is known about their impacts on soil microbial functional diversity, and especially so in irrigated Mediterranean ecosystems. In long-term experimental plots at the West Side Research and Extension Center in California's Central Valley, we ...

The study was conducted to evaluate hydraulic conductivity functions in relation to some soil chemical properties in an oxisols of the tropics. Field and laboratory studies were carried out and data collected, subjected to statistical analytical procedure for computing coefficient of variability and correlation among soil properties. Results of the study showed that hydraulic conductivity funct...
