土壤肥力评价,对世界任何国家维持农业产量都是十分重要的。在印度,土壤测定是作为评价土壤供给植物养分能力的一种新的手段。1956—1957年,印度与美国合作,在十五个土壤化验室开始从事这项工作。最初,主要致力于建立土壤测定设备,确定土壤取样和分析技术及其阐述方法的标准化。几年中间,在推广根据土壤测定制成的土壤肥力评价表方面,取得了引人注目的进展。六十年代,普遍推广了土壤肥力评价表。具有深远意义的是
Soil fertility assessment is very important for any country in the world to sustain agricultural production. In India, soil testing is a new tool for assessing the soil’s ability to supply nutrients to plants. From 1956 to 1957, India and the United States started to carry out this work in 15 soil laboratories. Initially, the main focus was on the establishment of soil testing equipment to determine the standardization of soil sampling and analysis techniques and their elaboration methods. In the middle of several years, remarkable progress has been made in the promotion of soil fertility assessment tables based on soil testing. In the 1960s, soil fertility assessment sheets were widely promoted. It is of far-reaching significance
