Change Analysis of Soil Nutritions in Manas
摘要
Abstract
The spatial variabilitys of soil have significance influence to reveal the distribution of the va-rious nutrients properties and develop specific field management measures and implementing precision agri-culture .This article comparative analyzes the nutrition change in temporal and spatial variation between 1982 and 2012 in manas farmland topsoil ,including soil organic matter ,alkali-hydro nitrogen ,effective phosphorus , rapidly - available potassium and pH .The results indicate that during 30 years soil nutritions in the study area showed a certain spatial variability change of organic matter ,alkali solution ni-trogen ,effective phosphorus ,rapidly -available potassium content and pH value ,each of nutrition’s level has growed ,the variation coefficient of organic matter and effective phosphorus is most obvious .Overall , the content of general nutrient in Manas research area by the 1980 is the"lack of phosphorus and nitrogen potassium rich "into the "average nitrogen and phosphorus ,potassium rich".关键词
