Description

It appears more and more clearly that soil analysis is not sufficient to give a good approximation of the mineral status of grassland soils. In perennial crops leaf analysis and empirical critical levels are widely utilized. This grassland approach emphasizes the good results which can be obtained for nitro­gen, potassium, phosphorus not from leaf but from the whole herbage plant analysis. This paper deals with pure grass stands.
