Zinc Sulfate For Plants

Zinc sulfate monohydrate for plants is a soil amendment that provides plants with an important and essential micronutrient, zinc. Its required by plants for many vital processes, including photosynthesis, enzyme production, and protein synthesis. Zinc, zn, deficiency in plants can lead to stunted growth, reduced yield, and poor crop quality. This is an effective way to correct zinc deficiencies in the soil and improve plant growth and development. On this page, we will discuss the benefits of zinc sulfate soil amendment, its application methods, and why its so good for pecan trees.

Benefits of Zinc Sulfate

1.  Promotes Plant Growth and Development

Zinc is an essential micro-nutrient for plant growth and development. It is required for the synthesis of enzymes and proteins, which are essential for plant metabolism. Zinc also plays an important role in the formation of chlorophyll, which is necessary for photosynthesis. Zinc sulfate soil amendment provides plants with the necessary zinc to promote healthy growth and development.

2.  Increases Yield and Quality of Crops

Zinc sulfate can increase the yield and quality of crops. Zinc is required for the production of plant hormones, which regulate plant growth and development. Zinc is also essential for the production of fruit and seeds, which are important for crop yield. This can improve the health and productivity of crops, especially those that are deficient in zinc.

3.  Improves Resistance to Stress

Zinc sulfate can improve the resistance of plants to environmental stress, such as drought, high temperature, and low humidity. Zinc is necessary for the synthesis of stress-related proteins that help plants to adapt to adverse conditions. This can help plants to withstand stress and maintain healthy growth.

4.  Prevents Nutrient Deficiencies

Zinc sulfate soil can prevent nutrient deficiencies in plants, especially in soils that are deficient in zinc. Zinc deficiency can lead to stunted growth, chlorosis, and reduced yield. This can provide plants with the necessary zinc to prevent these symptoms.

Application Methods of Zinc Sulfate

1.  Broadcast/Soil Application

Zinc sulfate can be applied to the soil as a dry fertilizer. It is usually applied to the soil before planting or during the growing season. The recommended amounts of zinc vary depending on the crop and soil conditions. It is important to apply zinc sulfate evenly and to avoid applying it in concentrated areas.

2.  Foliar Application

This is 100% water soluble zinc and can also be applied as a foliar spray to the leaves of plants. Foliar application is usually done during the growing season and is effective for correcting zinc deficiencies in plants. The recommended rates vary depending on the crop and stage of growth.

3.  Seed Treatment

Zinc sulfate fertilizer can be used as a seed treatment to provide young plants with the necessary zinc for growth and development. Seed treatment is usually done before planting and is effective for crops that have a high demand for zinc, such as corn and wheat.

4.  Side Dress Application

Zinc sulfate can be applied as a side dressing during the growing season. Side dressing is the process of applying fertilizer to the soil around the base of the plant. This method is effective for crops that have a high demand for zinc, such as corn and wheat.


Zinc sulfate fertilizer is an important micro-nutrient fertilizer that can improve plant growth and development, increase crop yield and quality, improve resistance to stress, and prevent nutrient deficiencies.

Zinc Sulfate for Pecan Trees

Zinc is an essential nutrient for pecan trees. It plays a role in the development of new leaves and flowers, as well as in the growth and production of nuts. Pecan trees that are deficient in zinc will not produce as many nuts as those that are properly fertilized with zinc.  We discuss how much zinc sulfate for pecan trees and the application rate below.

Zinc Sulfate for Gardens

One of the most disheartening obstacles are areas where the topsoil was removed during construction. Even with the addition of generous amounts of compost, the soil often lacks micronutrients such as zinc. The symptoms of insufficient zinc are similar to those of iron deficiency: stunted plants with small, yellowed and deformed leaves.

Prilled Zinc Sulfate

Our Zinc Sulfate is not powder but an easy to work with granulation called mini prill.  You could fit 3 or 4 of these mini prill balls into a BB size.  We package our zinc sulfate in factory sealed thick plastic bags.  This helps protect the product from outside elements and moisture.

How Much Zinc Sulfate For Pecan Trees?

Pecan trees use lots of zinc. It is an essential nutrient for strong growth and heavier nut production. Mostly, zinc sulfate applied to pecan trees as a foliar spray early spring. When applying this way, the trees can absorb the zinc right away. Young trees and vegetating trees need applications of zinc on new growth during the spring starting at budbreak and continuing for three sprays at 2- to 3-week intervals.  So, how much zinc sulfate pecan trees you ask?  Zinc sulfate is the primary source of zinc used by pecan farmers and should be mixed at 2 to 3 pounds per 100 gallons of water.

Soil applications of zinc sulfate are far less effective than foliar applications and are only useful when the soil pH is below 6.0. If soil pH is below 6.0, then a 1/2 pound of zinc sulfate per year of age of the tree can be soil-applied under the tree up to 10 pounds of applied zinc per tree total.  Be sure to apply around the canopy of the tree and NEVER near the trunk of the tree. Even so, a foliar application is more effective and is the preferred application method.

Why Use Zinc Sulfate For Pecan Trees?

Zinc is one of the most essential nutrients for pecan trees. It plays a critical role in the growth of new leaves and flowers, as well as in the growth and heaviness of nuts. Pecan trees that are zinc deficient will not produce as many heavy nuts, as well as a sparse yield in general, as those that are properly fertilized with zinc.

If pecan trees are planted in soil with low levels of zinc, you can guarantee that your pecan tree will show signs of being short of zinc.  Zinc deficiency can cause the leaves of the tree to wave or curl, or have long branches with only a clump of leaves.  Along with those symptoms you will find more common symptoms like yellowing of leaves and very slow growth.  For more information on tree health from a tree service please visit our friends at
