Temporal-Spatial Variation of Soil Organic Matter and Total Nitrogen in Rubber Plantations in Yangjiang State Farm
摘要
Abstract
The temporal-spatial variation of soil organic matter and total N content in rubber plantations in Yangjiang State Farm from 1983 to 2007 was studied by using geographical information system (GIS) and Geo-statistics. Results indicated that the contents of organic matter and total N in the soil decreased in more than 20 years, and that spatial variation of organic matter and total N content of the soil was reduced, with their contents tending to be reduced at a similar level and their spatial variation tending to be similar. These changes may mainly be due to production management and fertilizer application. At the same time, with the accumulation of impact from production management and fertilizer application and other human activities, the spatial variation of organic matter and total N contents of the soil was reduced and tended to be homogeneous.关键词
