🧪 Product Overview

Urea-Based NPK Blends are multi-nutrient fertilizers that combine the rapid nitrogen release characteristics of urea with balanced phosphorus and potassium nutrients, delivering a complete fertilizer solution in one product. These blends are formulated to meet the specific nutritional demands of various crops and soils, optimizing plant growth, yield, and quality.

The addition of urea enhances nitrogen availability, encouraging vigorous vegetative growth and higher protein content, while phosphorus and potassium support root development, flowering, fruiting, and overall plant health.

✅ Key Features & Benefits

Balanced Nutrient Supply: Provides essential macronutrients N, P, and K in one blend for efficient fertilization
High Nitrogen Efficiency: Urea component ensures rapid nitrogen availability for immediate plant uptake
Customizable Formulations: Nutrient ratios tailored to crop type, soil fertility, and growth stage
Improved Crop Yield & Quality: Supports robust root systems, improved stress tolerance, and enhanced fruit/seed quality
Versatile Application: Suitable for soil broadcasting, band placement, fertigation, and foliar feeding
Good Physical Properties: Free-flowing granules that reduce dust and improve spreading uniformity

Reactivity Profile:

UREA is a weak base. Reacts with hypochlorites to form nitrogen trichloride which explodes spontaneously in air [J. Am. Chem. Soc. 63:3530-32]. Same is true for phosphorus pentachloride. It reacts with azo and diazo compounds to generate toxic gases. Reacts with strong reducing agents to form flammable gases (hydrogen). The heating of improper stoichiometric amounts of urea and sodium nitrite lead to an explosion. Heated mixtures of oxalic acid and urea yielded rapid evolution of gases, carbon dioxide, carbon monoxide and ammonia (if hot, can be explosive). Titanium tetrachloride and urea slowly formed a complex during 6 weeks at 80° C, decomposed violently at 90 C, [Chem. Abs., 1966, 64, 9219b]. Urea ignites spontaneously on stirring with nitrosyl perchlorate due to the formation of the diazonium perchlorate. Oxalic acid and urea react at high temperatures to form toxic and flammable ammonia and carbon monoxide gases, and inert CO2 gas [Von Bentzinger, R. et al., Praxis Naturwiss. Chem., 1987, 36(8), 41-42].

Not flammable (USCG, 1999)
