The Categories And Functions Of Organic Fertilizer (One)

  The main categories of organic fertilizer include composting, manure, green manure, human and animal manure urine and other farm manure as well as factory production of organic fertilizer. Organic fertilizer contains a comprehensive range of nutrients, including major elements, trace elements and many physiological active substances, hormones, vitamins, amino acids, glucose, DNA, RNA and enzymes. Therefore, it is called complete fertilizer. 
   Compost is a kind of organic fertilizer composed of crop stalks, weeds, leaves, garbage and other organic waste as the main raw material, with a certain amount of feces, urine, sewage and a small amount of soil, which is decomposed by anaerobic microorganisms. The composting process is a process in which microorganisms decompose organic matter, so conditions suitable for microbial activities must be created. Compost must maintain enough moisture, control the moisture content of about 65 percent of the weight is advisable, which can be used as base fertilizer. the simple groove truning machine is the main turner machine in the compost process of organic fertilizer.
  Barnyard manure, also known as circle manure, which is made of manure and urine in domestic livestock pen and pad into the weeds and leaves, soil, such as peat material, through the post from the fertilizer. The farmyard manure contained three elements of nitrogen, phosphorus and potassium, among which the content of potassium was high, which could be directly absorbed by fruit trees. 
  Green manure was also one of the sources of orchard base fertilizer, and has high fertilizer efficiency.
Material is crushed into 10 cm uniform, spread on the surface of the field, drying for a long time can be turned into the soil. It is advisable to turn over 1000~1500 kg/acre; In the orchard with water watering condition, irrigation once every 1-2 days is beneficial for green manure to be ripe; No water pouring conditions, to be the arrival of the rainy season will be ripe.
  Most organic fertilizers need to be decomposed and released by microorganisms before they can be absorbed by the root system of fruit trees. Therefore, they are also called delayed effect fertilizers and are often used as base fertilizers.
