Resumen
Descripción
In China the research group visited Peking, the Provinces of Jiangsu, Guangdong, Hebei, Shanxi and the municipality of Shanghai. The member of the group were deeply impressed by the agricultural, economic and cultural achievements of the People?s Republic of China. They gained valuable experience, especially in the field of recycling of organic wastes in agriculture which will be most useful in the development of agriculture in their own countries. The major part of the report is devoted to the main subject of the Study Tour and it emphasizes the practical aspects and applicability of the methods studied in China. At present, about two-thirds of the total nutrient intake is derived from natural manures and heavy reliance on these manures will continue because the Chinese have developed a long standing experience in matching the various types of organic manures to their local soils. While mineral fertilizers are relatively costly, organic manures are constantly available locally at litt le or no cost except in manpower.
