Abstract
AbstractResults are given for the effects of heavy dressings of nitrogen, in the presence and absence of phosphorus and potassium supplements, on: dry‐matter yield; botanical composition of herbage; contents of crude protein, phosphorus, potassium, calcium, magnesium, sodium and manganese. Brief reference is also made to the effects of the various experimental treatments on the uptake of certain other trace‐constituents.The results indicate that high yields of pasture herbage having high protein and normal mineral contents can be maintained over a period of years by the use of fertilizer nitrogen, provided adequate fertilizer dressings of other major nutrients are given. Attention is drawn to various ion‐antagonism effects that may influence the mineral composition of the herbage.
