Previous research on land applications of manures has focused on soil fertility and the relationship to final crop yield, but there is little research that quantifies the effects of changes in soil physical and chemical ...

During the last two decades, an increasing number of producers have adopted a no-tillage or minimum tillage system because of the potential to reduce soil erosion, conserve soil moisture, improve soil structure and ...

The effect of repeated (4 years) manure applications on some soil quality indices such as pH, EC, SAR, bulk density, and aggregation was evaluated. The study was conducted at two sites (Burr and Dixon) in the Black Soil ...

Hog manure is valued as a source of plant nutrients but there is concern that land application of large volumes of hog manure applied repeatedly over many years, may deteriorate the quality of local soils, reduce crop ...

The long-term impact of repeated applications of high rates of liquid hog manure on the quality of the soil and that of the environment is not well known. For optimal application rates of hog manure, improved knowledge is ...
