Role of Gypsum in Agriculture: 20 Key Benefits you need to Know

While farmers have been using gypsum for centuries, it has received more attention in recent years. Gypsum is calcium sulphate.

Regular use of gypsum is important for maintaining sustainability of most irrigated soils. Irrigated land eventually leads to sodicity and salinity. So, one should take extreme care.

Gypsum is a key constituent used in agriculture. You can also use Gypsum while constructing house. In order to get fine quality Gypsum, you would require a reputed supplier.

A reputed Plaster of paris Manufacturer in Rajasthan will offer you items which are really very affordable and cost effective.

Major Benefits of Gypsum are as follows:

1.      Gypsum Improves Water-Use Efficiency:

Gypsum increases water-use efficiency of crops. In areas and times of drought, it is very important.

Improved hydraulic conductivity of soil, improved water infiltration rates, better water storage in the soil will lead to deeper rooting and better water-use efficiency.

From twenty five to hundred percent more water is available in gypsum-treated soils than in nontreated soils.

2.      Gypsum Makes it Possible to Efficiently Use Low Quality Irrigation Water:

Use of reclaimed municipal waste water is essential for conservation of natural resources.

Reclaimed water could be used satisfactorily if products, like gypsum and water-soluble polymers are being used.

3.      Gypsum Improves Fruit Quality and Prevents Some Plant Diseases:

Gypsum is used for peanuts, which develop below ground and keep them disease free. Root rot of avocado trees cased by Phytophthora is even corrected by gypsum and organics.

4.      Gypsum Can Increase Crop Yields:

Gypsum can substantially increase crop yields from ten to fifty percent.

5.      Gypsum Can be a Source of Oxygen for Plants:

Sulphate which is taken up by plants releases oxygen which is the major source of oxygen to plant roots although a limited source.

6.      Gypsum Decreases the Toxic Effect of NACL Salinity:

Calcium from gypsum has a physiological role and it inhibits the uptake of sodium by plants.

7.      Gypsum Decreases Dust Erosion:

Use of gypsum decreases wind and water erosion of soil. Especially when combined with water-soluble polymers, severe dust problems can be cured.

8.      Gypsum Prevents Water Logging of Soil:

Gypsum increases the ability of soil to drain and not become waterlogged due to a combination of excess water, high sodium, and swelling clay.

9.      Gypsum Corrects Subsoil Acidity:

Gypsum can correct subsoil acidity. Surface crusting can be prevented. Gypsum is now being broadly used on acid soils.

10.  Gypsum Can improve the Value of Liming:

Addition to soil together with lime can increase crop yield. The combination will decrease leaching loss of potassium and magnesium.

.

11.  Gypsum Creates Favourable Soil EC:

Gypsum results in proper buffered solute concentration (EC) in soil and maintains soil in a flocculated state.

12.  Gypsum Improves Low-Solute Irrigation Water:

Gypsum is used to enhance the solute concentration of low-solute water used for irrigation.

Irrigation water from river penetrates poorly into the soil and causes soil particles to degrade which in fact results in low-water penetration. This problem can be corrected with surface-applied gypsum.

13.  Gypsum Decreases pH of Sodic Soils:

Gypsum will reduce the pH of sodic soils or near sodic soils from values often over nine but usually over eight to values from 7.5 to 7.8.

These values are acceptable for growth of most crop plants.

14.  Gypsum Improves Swelling Clays

Gypsum will reduce swelling and cracking of the montmorillonite-type clays. As sodium is replaced by calcium, they swell less.

It therefore does not easily block the pore spaces through which air, water and roots move.

15.  Gypsum Can Help Remove Excess Boron from Sodic Soil:

When gypsum is applied more boron will leach from sodic soils.

16.  Gypsum Increases the Stability of Soil Organic Matter:

Gypsum is a source of calcium and is a major mechanism which binds organic matter in soil. It gives stability to soil aggregates.

17.  Gypsum Makes Water-Soluble Polymer Soil Conditioners More Effective:

Gypsum can improve the beneficial effects of water soluble polymers used as amendments and it can also improve the soil structure.

18.  Gypsum Improves Soil Structure:

Gypsum helps to improve aggregation and inhibit or overcome dispersion in sodic soils. Soluble calcium increases soil aggregation and porosity to improve water infiltration.

19.  Gypsum aids Seed Emergence:

Gypsum prevents crust formation on soil surface which result from rain drops or from sprinkler irrigation on unstable soil.

It also prevents crusting which results when acid soils are lime& the gypsum is co-applied with the lime.

20.  Gypsum Increases Value of Organics:

Gypsum can increase the value of organic amendments.

Conclusion:

1.       Source of calcium and sulphur for plant nutrition.

2.       Improves soil structure.

3.       Improves acid soils and treats aluminium toxicity.

4.       Improves water infiltration.

5.       Helps reduce runoff and erosion
