THE STATUS AND RATIONAL APPLICATION OF MAGNESIUM ON THE UPLAND RED SOILS OF FUJIAN,CHINA |
| |
| Abstract: | One of the more recent trends in Chinese agriculture is the rapid switch from the use of organic fertilizers,such as manure,to the use of chemical fertilizers.The most commonly used chemicals are either acidic or acid pro- ducing,and their use on red soils in Fujian has accelerated the increasing Mg deficiencies.Fifty-eight soil samples were taken from all types of red soil in Fujian and their total and exchangeable Mg contents were determined. Results have enabled us to suggest that regular soil testing,liming and the use of basic fertilizers,consideration of crop Mg requirements and planned crop rotations be considered when calculating the status of Mg in soils and optimum application rates for Mg fertilizers. |
