North-Eastern Sandy Highveld was utilized selectively by sheep grazing alone in winter with a supplementary lick. Winter utilization in four consecutive years had no detrimental effect on production, cover or seed production but care should be exercised in recommending this practice because of the tendency to start "winter" grazing in the critical autumn months and to continue grazing into spring. UITTREKSELNoord-Oostelike Sanderige Hoëveld was baie selektief benut waar skape alleen bewei het gedurende die winter met aanvullende lek. Alhoewel winterbenutting geen nadelige invloed op produksie, bedekking of saad produksie gehad het nie, moet die voorligter nog versigtig wees met sy aanbevelings, want die boer is bate geneig om sy winterbeweiding in die herfs te begin en dan die kort afgeweide gras weer vroeg in die lente te laat bewei.

In an experiment in which three levels of P and five levels of N fertilizer were applied, it was found that at the highest levels of fertilization the hay yields were increased fourfold, the percentage of crude protein was doubled, the crude-protein yield increased sevenfold, and the P uptake increased five times over those of the control. This increased production was mainly a result of the use of N fertilizer, although significant P x N interactions were obtained at the higher levels of N fertilizer. By itself, P fertilizer had little effect on any of the above increased yields. It would appear that very much higher production, especially of CP and P, might be attained, if even higher levels of fertilizer were applied. Basing income on hay yields and expenditure on fertilizer costs, the greatest profit was obtained from the higher levels of fertilization. This applied especially to N fertilizer.
