Lopez-Jurado, Gerardo

Abstract:

Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv.

Evaluation of Rhizobium strains with three Mediterranean forage legumes for biological nitrogen fixation

Creator:

Streeter, Donald J.

Abstract:

Centuries of continuous grain cropping in northern Africa have reduced N levels in soils to a degree such that agricultural production is now largely dependent upon nitrogen fertilizer. Through the identification of highly effective legume and Rhizobium strain combinations, the production of protein-rich livestock forage and green manure can be...
