Water-soluble fertilizers containing micronutrients play an indispensable role in plant growth. While their requirements are lower than macronutrients, they are higher than micronutrients, forming the backbone of plant nutrition. However, due to growers' insufficient understanding of micronutrients, their importance is often overlooked, leading to poor application results and impacting crop growth and yield.
The Role of Water-Soluble Fertilizers Containing Micronutrients
Water-soluble fertilizers containing micronutrients mainly include elements such as calcium, magnesium, and sulfur, with calcium and magnesium being crucial for crop growth. Calcium is an important component of cell walls, cell membranes, cell nuclei, cytoplasm, and cell sap, vital for crop physiological functions. Magnesium promotes photosynthesis, accelerates metabolism, participates in the synthesis of proteins, enzymes, and chlorophyll, and prevents yellowing leaves and diseases.
The Correct Application Method of Water-Soluble Fertilizers Containing Micronutrients
Most growers only apply calcium and magnesium during the fruit expansion stage, choosing inexpensive, single-ingredient products for foliar spraying. However, crops require calcium and magnesium supplementation at every growth stage. Therefore, the use of water-soluble fertilizers containing macro-, micro-, and macronutrients should be combined with topdressing and foliar spraying, and adjusted according to the crop's requirements.
Inter-element interactions
When using macro-, micro-, and macronutrients, attention should be paid to the antagonistic effects between elements to avoid improper use leading to reduced fertilizer efficiency. Most commercially available water-soluble fertilizers containing macro-, micronutrients are single-element and have low absorption and utilization rates. It is recommended to choose products produced using chelation and penetration-enhancing technologies, containing both calcium and magnesium, two essential macronutrients for crops, and which can be mixed with potassium dihydrogen phosphate, boron, and other elements.
Enhanced stress resistance
Choose products containing the core substance "adenosine triphosphate" (ATP). While supplementing calcium and magnesium, these products can also improve crop stress resistance, enhance crop growth under high or low temperature conditions, and reduce the occurrence of common diseases.
