Classification of compound fertilizers (crop aspect)

Rice specific

It is mainly made from urea, ammonium phosphate, and potassium chloride, with an effective nutrient content of ≥ 25% for nitrogen, phosphorus, and potassium. It can be used as base fertilizer and topdressing, with a general usage of 60-75 kilograms per mu. Base fertilizer accounts for 60-70% of the fertilization amount, and topdressing accounts for 30-40%.

Corn specific

Corn specific fertilizer is a specialized fertilizer produced with a professional formula based on the fertilizer requirements during the growth process of corn, which is suitable for the nitrogen, phosphorus, and potassium needs of corn

Dedicated to bamboo

It is made from urea, ammonium phosphate, and potassium chloride as the main raw materials, with an effective nutrient content of ≥ 28.5% for nitrogen, phosphorus, and potassium. 50 kilograms are used per mu, and weed control is combined between May and June each year, using strip or furrow application.

Tea specific

It is mainly made from urea, ammonium phosphate, potassium sulfate, and appropriate amounts of trace nutrients such as magnesium and boron. The effective nutrient content of nitrogen, phosphorus, and potassium is ≥ 25.0%. The fertilization amount is determined based on the yield of adult trees per mu. Generally, the yield of dry tea per mu is 50, 100, and 150 kilograms, and special fertilizers of 70, 90, and 120 kilograms are applied respectively. Apply according to the proportion of 50% of the total usage in the first month of spring tea extraction, 25% of the total usage after spring tea picking, and 25% of the total usage 15-20 days before autumn tea picking.

Tobacco specific

Generally, in moderately fertile fields, a rate of 50 grams per plant is applied by opening trenches and strips during tobacco transfer.

Potassium sulfate fertilizer

It uses urea, ammonium phosphate, and potassium sulfate as the main raw materials, with effective nutrient content of nitrogen, phosphorus, and potassium ≥ 36%. It is applied uniformly near the drip line of the tree crown at an age of 3-4 kg/plant year, and can be applied in a circular, circular, or strip manner. The ditch depth is 30CM.

Pollution-free fertilizer

It mainly uses urea, ammonium phosphate, and potassium sulfate as raw materials, with an effective nutrient content of ≥ 35% for nitrogen, phosphorus, and potassium. Fruits and vegetables are harvested at a rate of 80-150 kg/mu, with 30-60 kg as base fertilizer and 50-90 kg as topdressing. Leaf vegetables are harvested at a rate of 60-120 kilograms per acre, with 15-40 kilograms as base fertilizer and 40-80 kilograms as topdressing.

Eucalyptus specific

Eucalyptus specific fertilizer, abbreviated as eucalyptus fertilizer. It is a modern high-tech afforestation product carefully developed based on the unique physiological characteristics of eucalyptus trees, the latest technology of eucalyptus high-yield afforestation, and relevant scientific theories such as botany, soil nutrition, and forestry production. Not only does it scientifically combine rich nutrients such as ammonia, phosphorus, and potassium that are necessary for the rapid growth of eucalyptus trees, but also according to the fact that the soil in southern China generally lacks trace elements such as boron and zinc, and eucalyptus trees are mostly planted in mountainous and sloping areas with poor organic matter and fertility. Reasonable addition of various trace elements such as magnesium, copper, zinc, and organic matter containing humic acid can not only balance the nutrition of eucalyptus trees, enhance their growth momentum, but also effectively prevent the occurrence of physiological diseases such as shoot blight, ensure the healthy and rapid growth of eucalyptus trees, greatly improve the yield and yield of eucalyptus trees, and significantly increase production and income.

High concentration fertilizer

It mainly uses urea, ammonium phosphate, and potassium chloride as raw materials, with effective nutrient content of nitrogen, phosphorus, and potassium ≥ 45%. It can be used as base fertilizer and topdressing, and the application amount should be determined based on factors such as soil fertility and crop type.
