Can superphosphate be mixed with organic fertilizer? What is the effect of mixing superphosphate with organic fertilizer? We ask experienced netizens to help explain.Superphosphate is a cheap chemical phosphorus fertilizer commonly used in agricultural production, and its main components are calcium phosphate and monocalcium phosphate. Calcium phosphate is poorly soluble in water, making it difficult to exert its fertilizing effect. What can quickly exert a fertilizing effect is the monocalcium phosphate, which is present in no great amount in superphosphate.
But one of the biggest disadvantages of monocalcium phosphate is that it easily combines with certain inorganic elements in the soil to form poorly soluble substances and thus lose its fertilizing effect. Organic fertilizer can effectively overcome this shortcoming, and can also gradually convert the water-insoluble calcium phosphate into soluble form. Therefore, mixing superphosphate with organic fertilizer and applying them together can greatly increase the fertilizing effect.
Zhongdi Network has compiled the methods and characteristics of mixing superphosphate with organic fertilizer, and they are listed in detail below for netizens' reference.
Methods of mixing superphosphate with organic fertilizer:
Crush and sieve the superphosphate, take the powder and granules and mix them evenly with pig manure, chicken manure, cattle and sheep manure, barnyard manure, straw powder, etc. at a ratio of about 1:4, and after full fermentation, take the clumps and apply them into previously dug holes or trenches as a base fertilizer, then fill in soil and plant crops. The amount applied depends on need.
Benefits of mixing superphosphate with organic fertilizer:
Benefit one,It can reduce the contact of superphosphate with the soil, effectively preventing soluble phosphorus from becoming poorly soluble substances and reducing the fertilizing effect.
Benefit two,After superphosphate is mixed with organic fertilizer in clumps and applied to the soil, loose clumps form, water easily seeps in and dissolves the soluble phosphorus, and plant roots can also easily extend into the interior of the clumps to absorb the water-soluble phosphorus. Moreover, the root acid secreted by plant root tips and the organic fertilizer act slowly on the poorly soluble calcium phosphate at the same time, which can also gradually dissolve the calcium phosphate and thereby further increase the utilization rate of phosphorus in superphosphate.
Benefit three,Mixing superphosphate with organic fertilizer and applying them together also changes single fertilization into compound fertilization, increases the types of elements applied to plants, and also promotes plant absorption and utilization of phosphorus, better meeting the nutritional needs of crops.
Benefit four,After superphosphate is mixed with organic fertilizer and applied to the soil, it can overcome the drawbacks of conventional phosphorus application, such as affecting the normal life and activity of soil microorganisms due to excessively high soil phosphorus concentration and inhibiting plant absorption of nutrient elements, thereby protecting soil activity and also improving the efficiency of plant absorption of nutrient elements.
