Farmers often focus on the use of nitrogen fertilizer in their agricultural practices, but tend to neglect the importance of phosphorus, potash, and other essential micronutrients. This imbalance can lead to negative effects on both crop yield and quality. Identifying nutrient deficiencies through leaf symptoms is a practical way to guide farmers in making better-informed decisions for optimal production.
Potassium deficiency typically shows first on the older leaves of citrus plants, where the tips and upper margins begin to yellow. The discoloration gradually spreads downward, turning into yellow-brown or brown scorching. The leaf edges curl upward, and the leaves become distorted, with the tips drying out. The tree's crown appears weak, and new shoots are thin with small leaves. In severe cases, many shoots may die off during flowering, and the roots grow poorly, leading to an overall decline in tree health. Fruits may also be thin-skinned, less juicy, and more prone to spoilage.
Boron deficiency often starts at the growing tip, as if the plant has stopped growing. Root development is poor, and the leaves turn dark green, small, and thickened. Young leaves may be deformed or shriveled, with irregular yellowing between the veins. Flowers may not develop properly, and fruits can suffer from conditions like "berry heart rot" or root necrosis. Common examples include soybean "bud blight," apple "stunted growth," celery "stem cracking," and radish "heart rot."
Zinc deficiency causes leaf spots, clustered leaves, and shortened internodes, resulting in stunted growth and delayed maturity. Symptoms include leaf bleeding and the formation of distinct patterns on both sides of the leaves. Conditions such as "tree lobular disease" in fruit trees or "white corn seedlings" are often linked to zinc deficiency.
Experts recommend using "High-potassium Red," a high-efficiency foliar fertilizer rich in potassium, manganese, boron, and zinc. This product serves as an effective supplement for balancing nutrients and addressing deficiencies, making it an ideal choice for farmers looking to optimize crop performance without over-relying on nitrogen-based fertilizers.
