A Science-Based Nutrient Strategy to Overcome Quality and Yield Challenges in Winter Tomato Production Tomato is one of the most widely cultivated and highly commercialized vegetable crops worldwide. Combining high nutritional value with stable market demand, it plays a central role in protected agriculture and off-season production systems. In relatively warm regions such as subtropical and tropical areas, winter tomato production benefits from off-season market windows and

I. Executive Summary Entering late January 2026, the global fertilizer market is operating within a structural framework characterized by “high cost support + tight supply–demand balance.” In the Chinese market , phosphate fertilizers remain stable at elevated levels under the dual influence of supply-guarantee and price-stabilization policies together with persistently high raw-material costs. Potash prices are trending steadily upward, supported by low inventories and incre

Potassium hydroxide (chemical formula: KOH) is a strong inorganic alkali. Under ambient conditions, a 0.1 mol/L potassium hydroxide solution exhibits strong alkalinity, with a pH typically above 13. KOH appears as a white, uniform granular, powdery, or flake solid and is highly soluble in water, forming strongly alkaline solutions. I. Applications and Industrial Landscape of Potassium Hydroxide (1) Industrial-Grade Potassium Hydroxide: A Pillar of Basic Chemical Industry (App
