Ammonium Sulphate Nitrate
Ammonium Sulphate Nitrate is a compound quick‑acting nitrogen fertilizer. It combines the advantages of ammonium nitrogen and nitrate nitrogen sources, with balanced nutrient ratio and stable physicochemical indicators. It serves as a critical raw material of nitrogen fertilizer for agricultural production. The product delivers both fast nitrogen supply and long‑term slow release. It features good solubility and can supply nitrogen for crops rapidly. It can be applied directly or used as basic raw material for compound fertilizer production. It fits large scale field planting and cash crop cultivation, and enjoys wide application scenarios in the global agrochemical market.
1. Core Product Features
This product contains two forms of nitrogen, namely nitrate nitrogen and ammonium nitrogen. Nitrate nitrogen can be absorbed quickly by crops for instant nutrient supplement. Ammonium nitrogen can be adsorbed and retained by soil to supply nutrients continuously, realizing combined fast and slow fertilizing effect. The product has uniform regular granules, low impurity content and excellent water solubility. It dissolves fast in water with nearly no residue. With stable physicochemical properties, it resists caking under proper storage conditions, which facilitates transportation, stacking and mechanical spreading. This fertilizer contains no chlorine element and has wide application scope as well as good compatibility. It can be mixed and processed with most phosphorus and potassium fertilizers to produce various compound fertilizers, adapting to modern fertilizer processing technologies.
2. Agricultural Application Scope
This fertilizer is suitable for most grain crops and cash crops. Grain crops include wheat, corn, rice, sorghum and others. Application at vigorous nitrogen demand stages such as tillering and jointing can boost stem and leaf growth and improve crop vigor. It is also applicable to cash crops such as vegetables, fruit trees, oil crops and seedlings. It supplements nitrogen nutrition rapidly and promotes lush dark green leaves. It adapts to various soil conditions including dry land and irrigated land, and is especially suitable for crops that prefer nitrate nitrogen. It can be used as base fertilizer or top dressing to meet nitrogen requirements of crops in different growth cycles and help raise crop yield.
3. Application and Storage Precautions
As a nitrogen fertilizer, its application dosage shall be controlled. Excessive single application shall be avoided to prevent excessive vegetative growth or nutrient loss. Direct mixing with strongly alkaline fertilizers should be avoided to prevent nitrogen volatilization loss. Store in cool, dry and well ventilated warehouse. Keep away from moisture and rain, heat sources and direct sunlight. Do not stack together with flammable explosive, toxic or corrosive materials. Avoid heavy impact during handling. Use up as soon as possible after opening and keep sealed to prevent moisture absorption and caking, so as to maintain stable fertilizer nutrients.
