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

Urea and calcium ammonium nitrate (can) are both nitrogen fertilizers. How do their nitrogen supply effects differ, and how should they be chosen in practice? In today’s agricultural input market, an increasing number of distributors and growers are paying close attention to Calcium Ammonium Nitrate (CAN) . In certain application scenarios, CAN is even being used to partially replace traditional urea for topdressing. So, what are the fundamental differences between urea and

Potassium nitrate is a widely used binary compound fertilizer in agriculture, containing approximately 13% nitrogen (N) and 46% potassium oxide (K₂O) . It combines the functions of both nitrogen and potassium fertilizers, offering a balanced nutrient profile and excellent water solubility, allowing rapid uptake by crop roots. It is chloride-free , making it especially suitable for chloride-sensitive crops such as tobacco, potatoes, and citrus . Potassium nitrate effectively

Among the 17 essential nutrients required by plants, magnesium occupies a uniquely critical position . It is not only the only metallic element in the chlorophyll molecule , but also a key activator of plant energy metabolism . For modern agriculture—especially the cultivation of high-value cash crops—understanding the fundamental role of magnesium and mastering its efficient supplementation strategies is indispensable for achieving both high yield and premium quality.
