Mine Land Reclamation and Eco-Reconstruction in Shanxi Province I: Mine Land Reclamation Model

Table 2

The improvement measures for three typical reclaimed soils.

Reclaimed soil	Defect	Improved measures
Fly ash	Short of organic matter and nitrogenous fertilizer, bad field water performance, powerful heat absorptivity, fast heat, high pH value	Returning straw to field, rotation of green manure, the cooperation of organic and inorganic nitrogenous fertilizer, to transform pouring to sprinkling irrigation, laid straw interval, application of acid fertilizer
Mud	More clay particle, weak permeability, low content of organic matter	Returning straw to field, fly ash improvement, increment in humic and acid fertilizer
Rotten gangue	Low content of available water, strong endothermic character, fast heat, low content of nutrient element	Regular irrigation, keep a full stand of seedlings, laid straw interval, increment in humic and acid fertilizer
