Liquid slow-release nitrogen fertilizer Water soluble fertilizer containing humic acid Nitrogen ≥ 350g/L potassium≥ 20g/L humic acid≥ 30g/L1. Ferlikiss liquid slow-release nitrogen fertilizer, especially adding nitrification inhibitors: BASF VIBELSOL DMPP reduces nitrogen loss, improves nitrogen fertilizer utilization, extends the validity period of nitrogen fertilizer for 4-10 weeks, and protects the ecological environment. 2. The raw material of mineral humic acid comes from high-quality weathered lignite, and the advanced technology retains a variety of natural small molecule bioactive substances in mineral humic acid, adjusts the soil pH value, is conducive to the formation of soil aggregate structure, makes the soil loose and breathable, improves the soil environment, and protects the growth of crop roots. Peptide nitrogen source: Contains three forms of nitrogen source, combining fast-acting and long-acting to ensure balanced and long-lasting nutrient absorption and healthy crop growth. 3. Full water solubility: no impurities, especially suitable for drip irrigation, furrow application and foliar spraying, and can be used at the same time as other fertilizers, saving water, time and labor. High interest rate: more than 90% utilization rate, reduce pollution to water bodies, reduce costs, energy saving, environmental protection.
