Fertilization and Cultivation Soil (A) Fertilization: Flue-cured tobacco growth process requires a variety of nutrients, nitrogen, phosphorus and potassium three elements of large demand. Reasonable increase nitrogen, phosphorus and potassium fertilizer, can improve yield and quality. Application of excessive or insufficient growth of tobacco are extremely unfavorable, so a reasonable fertilization should note the following: 1 Shizujifei: basal fertilizer to account for the total amount of 60 to 70%, should be manure (dry cake, fire ash or Grass, ash, pigs and other livestock barn), with the application of phosphorus and potassium.
