Zinc is an element that is naturally present in rocks and eventually in soil. The zinc content in soil greatly varies depending on the material from which it is formed. The soil derived from igneous rocks has a higher amount of zinc, whereas sandy salts usually have a lower amount of zinc. This element is very crucial for plant growth and performs various crucial functions. This is why farmers supplement zinc sulphate to avoid any issues with plant growth. Let’s see some of the top reasons why zinc sulphate is used in agriculture:
To Enhance the Crop Quality
Zinc has an elementary role in the holistic development of plants, which includes crop quality. Farmers provide zinc sulphate to the plants so that their crop productivity is not hindered.
To Counter the Effect of Low Soil Temperature
When the soil temperature is very low, it impacts the mineralization process negatively. This often leads to less zinc release, which in turn affects plant growth. Farmers use zinc sulphate to counter this issue and support proper root development.
To Improve Soil Fertility
Soil fertility is one of the key factors that impact the health of plants. There are several crop types that grow on sandy soil with little to no organic matter. For such crop types and soil beds, the addition of zinc sulphate is crucial to achieving desired plant growth.
To Address Topsoil Erosion
Soil erosion is a common challenge faced in modern farming practices. Topsoil erosion often leads to increased concentrations of calcium carbonate. Zinc is needed to balance the excess calcium carbonate in the topsoil.
To Counter Excessive Phosphorous Fertilizer
When too much phosphorous fertilizer is applied to plants, the zinc concentration in the plants decreases. Additional zinc sulphate is required to balance both nutrients.
Zinc sulphate can be used in basal applications as well as foliar sprays to apply to crops. It provides zinc and sulphate to the soil, which is equally important for overall plant growth.
