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

China’s Annual Contract Anchors Global Pricing While Supply–Demand Dynamics Shape the Market In November 2025, China finalized its 2026 annual potash import contract—an event that quickly became the central anchor for global potash pricing. The agreement not only halted the price slide in several emerging markets but also ignited China’s winter fertilizer stocking season. At the same time, rising sulfur and sulfuric acid prices pushed production costs sharply higher, placing

In modern precision viticulture, Monopotassium Phosphate (0-52-34) has evolved from a supplementary foliar fertilizer into a central “physiological regulator”  applied across the entire grape growth cycle. Its value extends far beyond supplying phosphorus and potassium. What truly elevates MKP is its unique scientific profile—high solubility, pure nutrient forms, and synergistic absorption—which allows it to precisely activate photosynthesis, stress resistance, and quality f
