Fertility studies of pasture soils in the wet tropical coast of Queensland. 5. Mixed alluvial soils

Abstract

Results of sixteen plant growth experiments examining the nutritional status of mixed alluvial soils in the wet tropics are presented. A phosphorus deficiency is widespread and, in certain situations, extreme. Significant plant growth responses to calcium, copper, molybdenum, calcium + sulphur, magnesium + sulphur, and molybdenum + sulphur + manganese treatments were also recorded.
