Application methods of Geruilong special organic fertilizer in tobacco soil improvement
Special organic fertilizer for soil improvement
Geruilong special organic fertilizer for soil improvement was jointly developed by South China Agricultural University and Inner Mongolia Tianbaofeng Fertilizer Industry. It is a bio-organic fertilizer designed and manufactured to address the poor soil structure, deteriorated soil tilth and declining soil fertility caused by large-scale, long-term application of chemical fertilizers, at a time when arable land conservation is urgently needed. Geruilong special organic fertilizer for soil improvement can improve soil, increase yields and raise incomes. The fertilizer itself is loose in texture, porous and well aerated, with strong air and water permeability and excellent fertilizer- and water-retention performance. It contains appropriate amounts of nitrogen, phosphorus and potassium, secondary nutrients, and calcium, magnesium, sulfur and trace elements, with comprehensive nutrients and long-lasting fertilizer effects. This organic fertilizer can also be used as a premium nutrient medium for flowers and as a soilless culture substrate.
Suggested application methods:
When fertilizing soil after improvement, it is suggested to apply 300-500 kg per mu, mixed evenly with the topsoil during land preparation. When economic conditions permit or soil fertility is extremely low, it is suggested to apply 1000 kg per mu; during the crop growing period, apply additional organic-inorganic compound fertilizer as a topdressing, and a high yield can be obtained in the same year. After 3-5 years of continuous application, the productivity of the arable land can be restored, and the amount can then be reduced.
When used as a base fertilizer on general arable land, it is suggested to apply 150-300 kg per mu, preferably before land preparation or sowing; for paddy fields, it is preferable to apply before irrigation; during the crop growing period, it is suggested to apply it together with organic-inorganic compound fertilizer.
Special bio-organic fertilizer for tobacco
Geruilong special bio-organic fertilizer for tobacco was jointly developed by South China Agricultural University and Inner Mongolia Tianbaofeng Fertilizer Industry. This product is made from natural sheep manure through microbial fermentation, with the addition of nutrient elements essential for tobacco growth and development. Its active organic matter, humic acid and beneficial microorganisms have the effect of promoting tobacco growth and controlling tobacco diseases and insect pests. Nutrient supply is both slow and quick, providing not only major nutrient elements such as nitrogen, phosphorus and potassium, but also secondary and trace elements such as calcium, magnesium, sulfur, iron, manganese, copper, zinc, boron and molybdenum. It conforms to the fertilizer requirement pattern of tobacco plants, is conducive to tobacco growth, increases the potassium content and nicotine content of tobacco, and improves the quality of flue-cured tobacco. Besides promoting tobacco growth, it can also improve the physical and chemical properties of the soil, improve soil structure, and create a healthy growing environment for tobacco.
Suggested application methods:
Before transplanting tobacco seedlings, apply 100-200 kg per mu during land preparation; it can be broadcast on the bed surface or applied in furrows. For topdressing during the tobacco growing period, apply 40-60 kg per mu each time; the amount can be determined according to the growth and development of the tobacco.
