Attributes Analysis Of The Soil Nutrients In Certain Intra-counties, Jianghan Plain

Soil fertility is that soil has capabilities, which are comprehensive reflections on soil physical, chemical and biological nature, to coordinate and supply moisture, nutrients, air, heat and other conditions of life coinstantaneously and continuously in plant growth and development process. Soil fertility is that soil has capabilities, which are comprehensive reflections on soil physical, chemical and biological nature, to coordinate and supply moisture, nutrients, air, heat and other conditions of life coinstantaneously and continuously in plant growth and development process.This paper selects Soil samples from Dangyang , Yingcheng, Jianli, Tuanfeng, Xiaonan, Xiaochang and so on and conducts a comprehensive study and evaluation of organic matter, ph, nutrient content of necessary and useful various element and "3414"field test results. Based on a comprehensive study and evaluation of them,to obtain the following results can be obtained.(1) Based on soil sampling testing results of soil sample and statistical analysis of survey results of production levels and fertilization levels, Combined with the "3414" test results of different crops in different place and related history information,this paper formulates a preliminary evaluation index of the contents of regional soil nutrients and a nutrient application index of the main grow crops.(2)Based on evaluation results,this paper puts forward a reasonable balance fertilization countermeasures to mainly grow crops in regional landfarm soil.The above results have important guiding meaning and using valuefor currently being carried out work of soil testing Fertilization and useful guidance.
