FERTILISERS, LIME, AND TRACE ELEMENTS

Crops

The following common crops appear to have a greater need for readily available phosphorus than grass-clover pasture – potatoes, barley, and all brassica species including turnips, swedes, chou moellier, rape.

Autumn-sown wheat does not need a very generous supply of phosphorus, but spring-sown wheat may approach barley in its sensitivity to low levels of available phosphorus. The position of oats in relation to other crops and to pastures is not well known.
