The Alkaline soil conditioner--ferrous sulfate

Because soil exists bad properties and obstacle factors, the measures of some physics or chemistry solution should be taken, such as adding ferrous sulfate in the alkaline soil, improve the soil condition to improve soil fertility that finally increase crop yield.

Soil improvement process contains two parts: firstly, the soil conservation. Mainly apply engineering or biological measures to control soil erosion in the safe allowable range. Secondly, improve the soil quality. Its Purpose is to increase soil organic matter and nutrient content to increase soil fertility. Plant or farmyard manure is to increase fertility; Mix sand or stick soil together is to improve soil properties; Chemical modifiers are also one of these methods to improve acid alkaline soil.

Common chemical modifiers are lime, gypsum, phosphogypsum, ferrous sulfate, etc. According to the soil nature, it’s added different modifiers. For alkaline soil, it usually needs gypsum, phosphogypsum, ferrous sulfate etc; For acid soil, it usually needs calcareous material.
