  • Urea

    Urea

    Lemandou urea with a 46 percent nitrogen content, is a solid nitrogen fertilizer product. Urea fertilizers are widely used in agriculture. It is the most common form of nitrogen fertilizer used around the world. They are considered an economic nitrogen source. Produced from ammonia and carbon dioxide, it has the highest nitrogen content of any solid nitrogen fertilizer.  As a granular product, urea can be applied directly to the soil using conventional spreading equipment. In addition to soil applications, urea fertilizers can be also used in fertigation or as a foliar application. However, urea fertilizers should not be used in soil less culture, as urea will immediately leach out of the container.

  • Ammonium Sulphate

    Ammonium Sulphate

    A good nitrogen fertilizer (commonly known as fertilizer field powder) is suitable for general soil and crops. It can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance crop resistance to disasters. It can be used as base fertilizer, topdressing fertilizer and seed fertilizer.

  • Magnesium Sulphate

    Magnesium Sulphate

    MagnesiumSulphate can provide rich nutrients for crops that it contributes to crop growth and increase the output, it also helps to loosen the soil and improve soil quality.

  • Potassium Sulphate

    Potassium Sulphate

    Potassium sulfate is an inorganic salt with the chemical formula of K Ψ so ₄. Generally, the content of K is 50% – 52%, and the content of S is about 18%. The pure potassium sulfate is colorless crystal, and the appearance of agricultural potassium sulfate is mostly light yellow. Potassium sulfate is a good water-soluble potassium fertilizer because of its low hygroscopicity, low caking, good physical properties and convenient application. Potassium sulphate is especially suitable for the economic crops, such as tobacco, grape, sugar beet, tea plant, potato, flax and various fruit trees. It is also the main raw material for the production of chlorine free nitrogen, phosphorus, potassium ternary compound fertilizer. Potassium sulfate is a chemical neutral, physiological acid fertilizer, which is suitable for a variety of soil (excluding flooded soil) and crops. After being applied to soil, potassium ion can be directly absorbed by crops or absorbed by soil colloids. The results showed that potassium sulfate could be applied to Cruciferae crops and other crops which need more sulfur in the soil with sulfur deficiency.

  • Zinc Sulphate

    Zinc Sulphate

    It can be used to prevent the diseases of fruit tree nursery, and it is also a common fertilizer to supplement crop zinc trace element fertilizer. It can be used as base fertilizer, foliar fertilizer, etc. [6] Zinc is one of the essential nutrient elements for plants. The white flower seedlings are easy to appear in maize due to zinc deficiency. When the zinc deficiency is serious, the seedlings will stop growing or even die. Especially for some sandy loam soil or fields with high pH value, zinc fertilizer such as zinc sulfate should be applied. The increase of zinc fertilizer also has the effect of increasing yield. Fertilization method: take 0.04 ~ 0.06 kg zinc fertilizer, water 1 kg, seed dressing 10 kg, pile up for 2 ~ 3 hours sowing. Before sowing, zinc fertilizer was applied to rhizosphere layer with 0.75-1kg/mu. If the leaf color is light at seedling stage, zinc fertilizer can be sprayed with 0.1kg/mu
