Abstract
The effects of applications of biuret to Digitaria swazilandenis, Cynodon dactylon, Eragrostis curvula and sugarcane are described. Slight leaf tip‐burn was observed in the cases of the Digitaria, Cynodon and Eragrostis a few days after application of the biuret but sugarcane was not affected. The results show that crude biuret can be used effectively as a source of nitrogen by pastures, lawn grasses and sugarcane.
Crude biuret is sometimes included in the rations of ruminants to provide extra protein in the diet. Should any biuret pass out unchanged in the dung or urine it would be beneficial rather than detrimental to veld or pasture.
UITTREKSEL
Die uitwerking van toediening van biuret op Digitaria swazilandensis, Cynodon dactylon, Eragrostis curvula en suikerriet word beskryf. Blaarpuntskroei in ‘n geringe graad is binne ‘n paar dae vanaf toediening van die binrel waargeneem in die geval van Digitaria, Cynodon en Eragrostis. Suikerriet is egter nie beskadig nie.
Die resultale toon aan dat ru‐biuret met goeie gevolge gebruik kan word as ‘n bron van stikstof vir aangeplante weidings, grasperke en suikerriet. Biuret word dikwels as aanvullende proteïen gebruik in rantsoene vir herkouende diere. Enige biuret wat deur ‘n dier in die mis of urine uitgeskei mag word is voordelig, en nie skadelik vir die veld of aangeplanteweidings nie.
