Evaluation on Soil Nutrient Contents Characteristics in Liushu Township and Longquan Town of Yongdeng Country
摘要
Abstract
The 64 soil samples of Longquan town and Liushu township in Yongdeng county after crop harvest laboratory analysis shows that organic matter content in the lower level(10~20 g/kg),the total nitrogen in the upper level(1.0~1.5 g/kg), alkaline nitrogen is lower level(60~90 mg/kg)in different crop plots. In different administrative region,the soil organic matter,total nitrogen and total potassium content compared with the second soil survey increased by 4.5,0.3,1.8 g/kg;soil alkaline nitrogen,soil available phosphorus and potassium than the second soil survey increased by 25.26,13.74 and 37.60 mg/kg;the average soil total phosphorus content when compared with the second soil survey did not change obviously. Thus,8 administrative villages in Yongdeng County,Longquan town and willow Township different crop distribution of soil organic matter in poor state,available nitrogen increased,but lack of available,phosphorus is in the middle level,available potassium is in a rich level,but it is in a downward trend.关键词
