Effect of the interaction of nitrogen and phosphorus on the growth of ryegrass

摘要

Abstract A pot trial on 3 soils with different P adsorption characteristics showed large positive N x P interactions on the growth of ryegrass. Plant response to both nutrients and the N x P interaction differed among the 3 soils, In all soils, ryegrass responded equally to P and N application and the response to N was associated with a lowering of the P content of ryegrass.
