FAQS on 21-7-7 water soluble fertilizer

Q: What is the NPK ratio of 21-7-7 water soluble fertilizer?

A: The NPK ratio of 21-7-7 water soluble fertilizer is 21% nitrogen, 7% phosphorus, and 7% potassium. It is ideal for promoting balanced plant growth and nutrient uptake. This formulation suits crops requiring higher nitrogen during vegetative stages.

Q: How does urea phosphate (UP 17-44-0) differ from standard water soluble fertilizers?

A: Urea phosphate (UP 17-44-0) provides 17% nitrogen and 44% phosphorus, focusing on root development and acidifying soil. Unlike 21-7-7, it lacks potassium but offers higher phosphorus content. Manufacturers often recommend it for specific crops like fruits and flowering plants.

Q: What factors influence MKP 00-52-34 fertilizer prices from suppliers?

A: MKP 00-52-34 fertilizer prices depend on raw material costs, production scale, and supplier location. Bulk orders from factories often reduce per-unit costs. Seasonal demand and international market trends also impact pricing.

Q: How to identify reliable water soluble fertilizer suppliers for MKP 00-52-34?

A: Look for suppliers with certifications like ISO or OMRI, verified customer reviews, and transparent product testing reports. Reliable factories often provide customized packaging and technical support. Compare samples and pricing before finalizing orders.

Q: Can 21-7-7 and MKP 00-52-34 fertilizers be used together?

A: Yes, combining 21-7-7 (high nitrogen) and MKP 00-52-34 (high phosphorus/potassium) optimizes nutrient balance during different growth stages. Ensure compatibility by checking solubility and pH levels. Consult manufacturers for tailored mixing ratios.
