First, iron fertilizer should not be applied to the soil iron fertilizer is easily fixed by the soil and converted into insoluble compounds, losing fertilizer effect. Foliar spraying should be used.
Second, phosphorus fertilizer should not be dispersedly applied. Phosphorus is easily absorbed by the soil and loses its effect. The contact area between phosphate fertilizer and soil should be reduced. It can be applied by ditching or hole application, and concentratedly applied near the root of the crop.
Third, potash fertilizer should not be applied in the later stage of crops. Potassium can be transferred from the lower part of the crop to the top of the young part of the re-use, potassium deficiency symptoms than the lack of nitrogen and phosphorus symptoms late. Potash fertilizer should be applied in advance at the seedling stage of the crop or in the middle and early stages of the jointing stage, or be used as a basal fertilizer at one time.
4. Urea should not be applied shallowly or before applying water. Applying urea to the soil should be converted to ammonium nitrogen, which is easy to lose water with the loss of water or by the effect of light and heat.
Fifth, rare earth fertilizers should not be directly applied to the soil in a small amount of rare earth fertilizers, the correct use of the method is the dressing of rare earth fertilizers or foliar spray.
Sixth, ammonium sulfate should not be shallow application and long-term use of ammonium sulfate should not be shallow, the depth should be more than 6 mm, immediately after application of soil. The fertilizer is a physiological acid fertilizer. Long-term use in a piece of land will increase the acidity of the soil and damage the soil structure. In alkaline soils, ammonium ions in ammonium sulfate will be absorbed. Sulfate ions will remain in the soil and react with calcium. So that the soil hardens.
Seven, with chlorinated fertilizer should not be applied to saline and alkaline soil and chlorine crops on the ammonium chloride, potassium chloride, etc. applied to the soil, chloride ions are left in the soil, long-term application will increase the accumulation of chloride ions in the soil, leading to soil acidification. Applying on saline ground will increase salt damage.
Eight, the unfamiliar farmyard manure and cake fertilizer should not be directly used. The unfamiliar farm manure and cake manure contain many kinds of eggs and germs. It will also produce a lot of carbon dioxide gas and heat. It will pollute the soil directly and accelerate the evaporation and burning of soil moisture. Crop roots affect seed germination. The correct method of use is to first fully compost the farmyard manure and cake fat, and use it after high temperature disinfection or chemical treatment.
Nine, compound fertilizer should not be used alone Compound fertilizer nutrients are relatively fixed, should be based on different soils, different crops, plants of different periods of the demand for various nutrients, and according to the growth of the crop at that time, and other fertilizers used in conjunction. For example, when diammonium phosphate is 18% nitrogen and phosphorus is 46%, when used in crops with more nitrogen requirements, the calculated amount of phosphorus is used. The insufficient nitrogen is supplemented with ammonium bicarbonate, urea and ammonium sulfate.
Organic turmeric extract is derived from the dried rhizomes of turmeric. Turmeric is a ginger plant with a botanical name of Curcuma longa L. The main ingredients of turmeric extract are curcumin. And the curcumin ratio can reach 95% or more. Turmeric has long been used as a natural pigment (E100) in the food industry. It has strong tinting strength, does not fade, but is sensitive to light, heat. Mainly used for dyeing canned foods, sausage products, and sauces.
