Abstract

Taking x County as the study object, doing experiment, calculation, comparison, this article analyzes the top-soil nutrients and PH value in field. The results showed that it has abundant organic content and teaches the standard of growing well for crops. The soil in X County has rich available content. If we take the measure-ment in available nitrogen of more than 120 mg/kg as high nitrogen supplying capacity, the soil of the whole county has high capacity in the short term. The phosphorus content is low. Most of the samples are in level five, accounting for 41.43%, and the content is not balanced in different villages and towns. The potassium content is low; PH value is suitable for growth. The survey result reflects the state of soil nutrients in different villages and towns in X County. It can provide important reference for ecological environment protection, farmers' scientific farming, increasing the income of farmers', reasonable fertilization, reducing soil and water pollution.
