Zinc deficiency in crops is one of the most widespread micronutrient problems affecting agricultural productivity. Common symptoms include leaf chlorosis, shortened internodes, clustered leaves, reduced plant height, stunted growth, poor seed filling, and lower yields. To address this issue, applying zinc fertilizer is an effective solution. When zinc is supplemented, crop growth and development are significantly enhanced, leading to improved seed-setting rates, better cold and disease resistance, and increased yields by 10% to 30%.
Zinc deficiency in soil is quite prevalent, especially in areas with high groundwater levels, winter fields, muddy soils, high altitudes, and low temperatures. Excessive use of compound and phosphate fertilizers can also trigger zinc deficiency, making it necessary to add zinc-based fertilizers. The adoption of hybrid varieties and high-yield farming techniques increases the demand for zinc, further emphasizing the need for zinc fertilizer application.
Zinc fertilizer is beneficial for a wide range of crops, including corn, wheat, cotton, rapeseed, fruit trees, vegetables, soybeans, peanuts, artichokes, and tobacco. Its application not only boosts yield but also improves product quality and overall crop health.
The method of applying zinc fertilizer varies depending on the type of soil:
1. **Paddy Soil**: Apply 200 grams of large-grain zinc per acre. It can be used as a seedbed fertilizer, mixed with granular fertilizer and fine soil before spreading during field preparation.
2. **Dryland Soil**: Use 200 grams of large-grain zinc per acre. Mix it with compound or blended fertilizer, or with fine soil, and apply it evenly before planting.
3. **Fruit Trees**: Apply 5 to 10 grams of large-grain zinc per tree (10 to 30 grains depending on the tree size). It can be combined with compound and organic fertilizers as a spring or fruit-enhancing fertilizer. Apply it along the drip line of the tree canopy after digging a trench.
It's important to apply zinc fertilizer early in the growing season for maximum effectiveness. Combining it with nitrogen, phosphorus, and potassium fertilizers enhances its performance and leads to better harvests. Always follow recommended application rates, as overuse can be harmful. Large-grain zinc has a residual effect, so it’s usually sufficient to apply it once a year or every other year in deficient fields.
