FERTILISERS, LIME, AND TRACE ELEMENTS
The main products of New Zealand agriculture are milk, meat, and wool. These are obtained from cattle and sheep which derive their feed almost entirely from pasture, that is, from grasses and clovers. Nevertheless, the largest acreage of crops is grown for supplementary livestock fodder and a much smaller acreage for human consumption. Since most of the fertilisers used in New Zealand are applied to pastures, it is this practice that is mainly discussed.
