متن کاملDifferential Soil Acidity Tolerance of Tropical Legume Cover Crops
In tropical regions, soil acidity and low soil fertility are the most important yield-limiting factors for sustainable crop production. Using legume cover crops as mulch is an important strategy not only to protect the soil loss from erosion but also to ameliorate soil fertility. Information is limited regarding tolerances of tropical legume cover crops to acid soils. A greenhouse experiment wa...
متن کاملMapping Historic Hookworm Disease prevalence in the southern Us, comparing percent prevalence with percent soil Drainage Type Using GIs
Mapping of Historic US Hookworm prevalence data from the Rockefeller Sanitary Commission (early 1900s) using current GIS (Geographic Information System) software (county shape files) illustrates the extremely high prevalence of hookworm disease (Uncariasis) in the Southeastern US at the time. Some counties in 7 states recorded 50% to 100% of the population with positive screens for hookworm in ...
