Soil Nutrient Analysis of Different Utilization Types in Coal Mining Subsidence Area

Soil nutrient of different utilization types in coal mining subsidence area had been analyzed. Results showed that: In greenhouse reclamation area, the content of organic matter and elements was higher, the pH-value was slightly high, followed by was cropland reclamation area; but in forest reclamation area (Include new reclamation area and intercropping reclamation area), as the reclamation and cropping were prolonged, soil fertility was improved.
