Interpretive Summary

Application of Dolomite on the Amelioration of Red-Yellow Soils in Southern Anhui Province, 2002. This fixed-site field trial is evaluating the effect of dolomite application in selected crops grown on acid soils. There are about 1. 2 million hectares (M ha) of acid soil in Anhui Province although acid soils are widely scattered throughout southern China.

Effects of dolomite on the amelioratin of red-yellow soils in south Anhui province, 2001 There are about 1. 2 million hectares (ha) of yellow-red soil in Anhui province, and it is widely scattered throughout southern China. The soil pH ranges between 4. 5 to 5. 3. The soil is not suitable for cultivation. Dolomite is a locally made, cost effective material, and its application to the area would bring the land into production and increase crop yields.

Aglime application for amelioration of acid yellow-red soil in South Anhui, 2000 There are about 1. 2 M ha of Yellow-red soil in Anhui province, and it is also widely scattered throughout southern China. The soil pH of Yellow-red soil ranges from 4. 5 to 5. 3. This is not ideal for agricultural production, therefore some land is not cropped.

Research and extension of aglime application for amelioration of acid yellow-red soil in south Anhui province, 1999 Approximately 1. 2 M ha of yellow-red soil exists in Anhui province, but this soil type is also widely scattered throughout southern China. Yellow-red soil characteristically has a low pH that ranges between 4. 5 and 5. 3, which places a restriction on its suitability for agricultural production.
