A soil amendment or soil conditioner helps improve the growth and health of plants. Whether or not it can be added, however, will depend on the type of plants, current soil composition, and the climate.

Soil amendments come in many types – lime, clay, gypsum, materials for water retention, and fertilizers for plant nutrients. Each one has a specific purpose.

Gypsum, in particular, improves soil structure and helps release nutrients.

But is it suitable for agricultural application?

Calcium Sulfate (CaSo4) or agricultural gypsum has the right content as a soil amendment for a farm and other agricultural areas.

It has soluble calcium that allows air and water movement by flocculating swelling clay soils and a sulfate form of sulfur that converts soil for plant use without acidifying it.

In addition, Agricultural Gypsum also:

  • Removes toxins from soil particles by displacing magnesium and prevent dispersion in the process.
  • Reduces toxicity of subsoil alum because of the mobile calcium that reaches subsoil levels.
  • Keeps dissolved phosphorus in the soil for plant use, preventing runoff

Reduces volatilization and stabilizes nitrogen in urea fertilizer

Despite these benefits, gypsum soil amendment is not widely used because of its above average cost.

But where agricultural gain is concerned, however, agricultural gypsum is the leading option.

What makes an effective choice is that it comes with properties that provide benefits for agricultural uses.

Source of plant nutrients

Sulfur is essential to crop yield, which nature provides through rainfall.

Recent studies show, however, that there is a decrease in sulfur inputs. Since agricultural gypsum contains 18.6% of sulfur, it can be used as a sulfur fertilizer to enhance production of crops, such as soybean and corn, in sulfur-deficient soils.

Because gypsum solubilizes slowly, it provides soil a continual release of sulfur for more than a year after it is applied.

It also has the calcium content needed to improve the quality of horticultural crops, which is why it is also used as a calcium fertilizer, especially when growing peanuts.

For disease-free peanuts, there should be adequate quantities of calcium present in the pegging zone, something that agricultural gypsum provides.

Improves soil structure

The structure of a soil can impact a variety of soil processes, including the way chemical and water are transported, wind and water erosion, soil aeration, and response to mechanical stress.

 

In semiarid to humid regions, soils have an unstable structure, making them difficult to manage and susceptible to erosion. But with gypsum’s ability to flocculate, soil is made compact and clay dispersion is prevented.

This, in turn, ensures a strong surface crust that is dependent on moisture content and clay.

For this reason, agricultural gypsum is used as an amendment for sodic soil management and reclamation.

Improves soil chemical properties

Plants can grow in acid soils, but their access to available aluminum and greater concentration of soluble is better when the soil’s pH is lower. The acidity in the subsoil also prevents roots from exploiting nutrients and water in the subsoil horizons.

By applying gypsum on the soil’s surface, root growth is improved and water stress is reduced. While agricultural lime and calcite lime can lower soil pH, only gypsum has the solubility that allows it to affect, at depth, the physical and chemical properties of soil.
