Besluitsorientasie deur inkrementele kostekalkulasie met spesiale verwysing na veldbemesting

Abstract

An increase in the world population constantly increases the demand for agricultural products. Consequently the agriculturalist continuously has to increase production. In South Africa, almost 90 per cent of arable land is already fully exploided and yields of cash crops can no longer be raised at will to meet increasing demands. More specific, the demand for red meat increased very sharply over the past decade and ways had to be found to meet this demand. Fortunately on a relatively large part of South Africa, unsuitable for crop production and used as pasture, production may be improved by applying some form of radical veld improvement. Veld fertilization as a means to increase production, was investigated by South African research workers for nearly half a century, however, they were not quite certain whether. it will be an economic practice, especially in the relatively lower rainfall areas. (In the vicinity of 600 mm/a). In these areas, veld fertilization is at present no farming practice but is restricted to agricultural research. For these reasons it is not possible to evaluate it from results as obtaining by farmers. Insufficient economic evaluation, to propagate this practice in general has been done.
