Characteristics and Application Methods of Ammonium Nitrate Phosphate Zinc Fertilizer Explained

Ammonium nitrate phosphate zinc is a multi-nutrient fertilizer that adds the element zinc to a nitrogen-phosphorus compound fertilizer base. Its nutrient content is generally indicated as a combination of nitrate nitrogen, ammonium nitrogen, phosphorus and zinc. The product is mostly granular, with a relatively uniform nutrient distribution and good water solubility. It is usually produced by processes such as melt granulation, combining the supply of quick-acting nutrients with trace elements.

Compared with ordinary nitrogen-phosphorus compound fertilizers, the nitrogen in ammonium nitrate phosphate zinc consists of both nitrate nitrogen and ammonium nitrogen, so it releases nitrogen relatively quickly while also having a certain lasting effect. Zinc is an essential trace element for crops, participating in the synthesis of auxin in the plant and in the activity of various enzymes. When applied to crops such as corn and rice grown on zinc-deficient soils, it helps reduce zinc-deficiency symptoms such as small leaves, white seedlings and stunted seedlings.

In terms of application, it can be used as a base fertilizer or as a topdressing, and is especially suitable for calcareous soils, alkaline soils and areas prone to zinc deficiency. The rate should be determined according to soil fertility, crop type and target yield, and it is best to arrange it reasonably in combination with soil test results. When used as a seed fertilizer or applied in a concentrated way, avoid direct contact between the fertilizer and seeds or roots to prevent seed and seedling burn; after application, cover with soil promptly and maintain suitable soil moisture.

During storage, it should be placed in a cool, dry, well-ventilated place, kept away from moisture and caking, and kept away from flammable materials, because fertilizers containing nitrate nitrogen have combustion-supporting properties. During use, it should not be mixed directly with alkaline fertilizers or alkaline pesticides, nor should it be applied alone for a long time. It is recommended to combine it with organic fertilizers and fertilizers containing potassium and secondary and trace elements to maintain soil nutrient balance, so that its fertilizer efficiency can be better brought into play.
