Why and How to Use Zinc Sulfate Monohydrate Fertilizer?

Zinc Sulfate Monohydrate fertilizer available in granulated form contains 35.5% Zn [Zinc] and 17% S [Sulphur]. It is applied directly in dry soil. You can even combine it with dry fertilizers and humates. The percentage to use will depend on the soil analysis report.

Strategies used to apply Zinc

  • To last for several years use Zinc at high-rate
  • To last one-year apply Zn at lower rates. [every time you have sown crops or once annually in vine crops or plantation]

Long- and short-term usage rates

For long-term use, the recommended rate of Zinc Sulfate Monohydrate ranges from 5kg/ha [on sandy soil pasture] to 30kg/ha [high-value crops on heavy soil]. The application needs to get repeated within 5 years of interval.

For short-term, a typical usage rate is 5kg/ha every year in annual or vine crops. The fertilizer is not recommended for use in crops planted with narrow spacing [18cm apart].

How zinc sulfate is helpful to the crops?

  • Zn is helpful in leaf sizing.
  • A leaf is the main solar panel.
  • The leaf’s overall surface area will define the sunlight amount plant can capture for its photosynthesis process.
  • Photosynthesis is liable for 90% of the overall plant functions, therefore enhancing the process enhances crop production.
  • When sufficient zinc level is supplied to the crops water absorption gets improved along with the development of flowers and fruits.
  • Water is necessary for uptake and translocation of nutrients within the pant. Enhancing water absorption allows getting good yields.

Benefits of Zinc Sulfate 35% fertilizer

  • Enhances crop amount
  • Helps leaf gets its green color early
  • Regulates the soil’s pH levels
  • Enhances plant’s durability against cold climate
  • Encourages the fruit trees to grow more fruits
  • Prevents deformation in fruits
  • Increases water transportation
  • Amplifies water holding capacity
  • Increases grain size thickness
  • Prevents the yellowing of meadow grass
  • Grows abundant of pasture fast

Crops responding largely to Zn

  • Corn
  • Dry edible beans
  • Apple
  • Snap beans
  • Apple
  • Sweet corn

Zinc deficiency symptoms

Due to a lack of zinc, the plants can’t develop normally. Certain deficiency symptoms start appearing. Below are some examples –

  • In corn, there is a development of striped tissue bands on leafs midrib. The stripes occur on the plant’s upper part. The corn plant will also appear stunted.
  • In edible beans, the lower leaves start yellowing. As the season moves the yellowing turns into brown or bronze. Its appearance looks rusty, so never confuse it with sunburns.
  • In soybean, the symptoms include chlorosis or interveinal mottling. Never confuse chlorosis to be iron deficiency.

Confirm the symptoms with a thorough plant tissue analysis. However, also combine the plant analysis with soil tests before you choose a Zinc fertilizer program. Zinc concentration in tissue differs between growth stages, so get familiar when to choose a plant analysis program to get an accurate report.

Zinc is toxic to sheep, so store it safely to avoid your animals from eating it. When you use Zinc Sulfate for hoof rot management carefully know the volume. Never overdose than what the veteran recommended. It is for external use. Wash your hands properly after use. Even clean the farm equipment after use because Zinc Sulfate is corrosive to metals.
