The effect of soil pH, stable manure and fertilizer nitrogen on the growth of red clover and of red clover associations with perennial ryegrass.
Year: 1962
Type: article
Abstract: In garden plots of pH6, response to added N was slight due to nodulation, N fixation and development of red clover at low N fertilizer levels. With increasing amounts of fertilizer N the production of grass increased considerably but clover production fell; clover production increased with N treatment in the absence of grass. Nodulation of clover in uninoculated plots was poor at soil pH5.8but inoculation with Rhizobium trifolii gave normal nodulation at pH 5.0. Increasing the supply of fertilizer N increasingly delayed nodulation. Stable manure promoted nodulation and N fixation in clover on uninoculated acid soil (pH 5.0); on uninoculated soil the effect was weaker. (Abstract retrieved from CAB Abstracts by CABI’s permission)
