Zinc deficiency in crops is one of the most widespread micronutrient issues affecting agricultural productivity worldwide. Common symptoms include leaf chlorosis, shortened internodes, curled or lobed leaves, stunted growth, reduced seed filling, and lower yields. To address this problem, zinc fertilizers are often applied, which can significantly boost crop growth, improve seed-setting rates, enhance resistance to cold and disease, and increase yields by 10% to 30%.
Zinc deficiency in soil is particularly prevalent in regions with high water tables, winter fields, wetlands, high altitudes, and cooler climates. Excessive use of compound and phosphate fertilizers can also trigger zinc deficiency, making it necessary to supplement with zinc-based fertilizers. Additionally, the adoption of high-yield hybrid varieties and advanced cultivation techniques increases the crop’s demand for zinc, further emphasizing the need for proper zinc supplementation.
Zinc fertilizer application has proven effective across a wide range of crops, including corn, wheat, cotton, rapeseed, fruit trees, vegetables, soybeans, peanuts, artichokes, and tobacco. It not only improves yield but also enhances the quality of the final product.
Here are the recommended application methods:
1. **Paddy Fields**: Apply 200 grams of large-grain zinc per acre. It can be used as a seedbed fertilizer in Putian, mixed with granular fertilizer and fine soil, and spread during land preparation.
2. **Dryland Soil**: Use 200 grams of large-grain zinc per acre. Before planting, mix it with compound or blended fertilizers, or fine soil, and apply it evenly on the field.
3. **Fruit Trees**: Apply 5 to 10 grams of large-grain zinc per tree, depending on the size of the canopy (approximately 10 to 30 grains). It can be combined with compound and organic fertilizers and used as a spring or fruit-enhancing fertilizer. Apply it along the drip line of the tree 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 can enhance its performance and lead to better harvests. Always follow recommended application rates, as overuse can be harmful. Large-grain zinc has a residual effect, so it can be applied once a year or every other year in deficient soils.
