Groundnut crops have been cultivated on sandy alluvial soil 900haj in Kuala Drang Malaysia since 1971. They are grown in rotation with rice or maize under village level technology using a mimimum amount of fertilizer nitrogen. To monitor changes in total soil A and the amount of \ removed by crop and weeds the Soil Science Department of Universiti Pertanian Malaysia in collaboration w ith the local Farmers Organisation Authority set up a small pilo t research p roject. The amount of \ removed by groundnuts and weeds and the level of soil A at the end o f one cropping phase were estimated from cropped and uncropped control plots.

Abstract

Groundnut crops have been cultivated on sandy alluvial soil 900haj in Kuala Drang Malaysia since 1971. They are grown in rotation with rice or maize under village level technology using a mimimum amount of fertilizer nitrogen. To monitor changes in total soil A and the amount of \ removed by crop and weeds the Soil Science Department of Universiti Pertanian Malaysia in collaboration w ith the local Farmers Organisation Authority set up a small pilo t research p roject. The amount of \ removed by groundnuts and weeds and the level of soil A at the end o f one cropping phase were estimated from cropped and uncropped control plots. Any average o 130 60 a nd 46 kg X .h a 1 a m i c r o /r was removed from plots sown to groundnuts as stubbles unshelled nuts and weeds respectively while 12 kg X .h a 1 c r o p 1 was obtained from weeds in control plots. The total soil X (0 -13 c m was estim a ted to he lO SO kg \.h a of groundnut plots and I4 S 0 kg A.h a 1 l or control plot. The significance ol these data is discussed in relation to tin overall economy of the system operating at the village level technology in Malaysia
