对某些基库尤牧场硝酸盐过量积累的某些因素进行了研究。积累，主要是在茎组织中，是几个促进过程的净结果。引起植物对同化氮物质需求下降的气候条件刺激氮的积累。高肥料氮的应用和氮物质在牧场的再循环似乎是相当重要的。这些高土壤氮水平与土壤中高钾水平相结合，有助于硝酸盐的吸收、转移和积累，似乎是硝酸盐积累的主要因素，特别是在古老的基库尤牧场。
A study was made of some of the factors responsible for the accumulation of excessive amounts of nitrate in certain Kikuyu pastures. Accumulation, mainly in stem tissue, is the nett result of several contributing processes. Climatic conditions causing a decline in the requirements of the plant for assimilated nitrogenous substances, stimulate accumulation. High fertilizer-N applications and the re-cycling of nitrogenous substances in the pasture seem to be of considerable significance. These high soil nitrogen levels in conjunction with high potassium levels in the soil, aiding nitrate absorption, translocation and accumulation, seem to be major factors responsible for the accumulation of nitrate, especially in old Kikuyu pastures.
