Fertilizer experiments on citronella grass (Cymbopogon winterianus Jowitt) were conducted on the lateritic red soil originated mainly from the weathered crust of basaltic materials in the northern part of Laichow peninsula, Kwangtung. The experiments covered the complete life cycle of citronella grass during the period from 1960 to 1963. The soil contains 2.21% of organic matter, 0.10% of nitrogen, and 8 mg/100 gm of exchangeable potassium, but it is low in available phosphorus. Chemical fertilizers were applied with compost as basic manure which was prepared from the distilled material of citronella grass and was dressed at a rate of 15,000 kg per hectare. The muddy compost contains only 11.63% of organic matter.
