Alsheikh, Abdulmagid M.

Abstract:

Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity.

Growth and mycorrhiza formation of Douglas-fir seedlings grown in soils collected at different distances from hardwoods pioneering southwest-Oregon clearcuts

Creator:

Borchers, Susan L.

Abstract:

A greenhouse bioassay was used to compare the effects of soils collected at different distances from hardwood species on the growth, mycorrhiza formation, and foliar nutrient concentrations of Douglas-fir seedlings. Soil nutrient concentrations and bulk densities were also determined. Soils were collected from two southwestern Oregon sites that had been...
