Special organic fertilizer for soil improvement

Gruilong special organic fertilizer for soil improvement is jointly developed by South China Agricultural University and Inner Mongolia Tianbaofeng Fertilizer Industry. Gruilong special organic fertilizer for soil improvement can improve soil, increase yield and increase income, which results in poor soil structure, poor soil tillage and soil fertility. The fertilizer itself has loose texture, loose porosity, strong ventilation and water permeability, excellent performance of fertilizer and water retention, and contains appropriate amount of nitrogen, phosphorus and potassium, medium nutrient elements, calcium and magnesium sulphide trace elements, comprehensive nutrients and long-lasting fertilizer effect. The organic fertilizer can also be used as a nutrient medium and soilless culture medium for high-grade flowers.

Recommended usage:

When fertilizing the improved soil, it is recommended to apply 300-500kg per mu, combined with soil preparation and topsoil mixing. When the economic conditions permit or the soil fertility is extremely low, it is recommended to apply 1000kg per mu, and the high yield can be obtained by topdressing organic-inorganic compound fertilizer in the crop production period. The productivity of cultivated land can be restored after continuous application for 3-5 years, and the dosage can be reduced in the future.

When general cultivated land is used as base fertilizer, it is recommended to apply 150-300kg per mu, suitable for soil preparation or before sowing, paddy field before irrigation, and combined application of organic-inorganic compound fertilizer during crop growth period.

In addition to promoting the growth of tobacco, it can also improve soil physical and chemical properties, improve soil structure, and create a healthy growth environment for tobacco.

Recommended usage:

Before transplanting tobacco seedlings, combined with soil preparation, 100-200kg per mu can be applied on the border or ditching. Topdressing of tobacco during the growing period, 40-60kg per mu, the amount can be determined according to the growth and development of tobacco.
