I. The Overlooked “Soil Condition”: Why Is Fertilization Becoming Less Effective? In many agricultural regions, farmers are not lacking in fertilization experience. Decisions such as when to apply nitrogen, when to supplement potassium, or when to add micronutrients are often based on long-established practices. However, in reality, many fields show no corresponding improvement in crop performance despite increasing fertilizer inputs year after year. Instead, problems such as

Plants determine whether an element is essential based on their own physiological and developmental needs. Elements in plant tissues are classified as essential  and non-essential . According to the required amount, essential nutrients are divided into macronutrients — nitrogen (N), phosphorus (P), and potassium (K); secondary nutrients — sulfur (S), calcium (Ca), and magnesium (Mg); and micronutrients — boron (B), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), molybdenum

Zinc is an indispensable “star micronutrient” in plant growth and development. It participates in chlorophyll synthesis, enzyme activation, nutrient metabolism and other key physiological processes, directly influencing crop yield and quality. However, traditional zinc fertilizers are easily fixed in soil, resulting in low availability. EDTA-ZnNa₂ (Ethylenediaminetetraacetic Acid Zinc Disodium), with its stable chelated structure, provides a more efficient and reliable soluti
