How to Use the Organic Fertilizer Correctly?

 Application for basic fertilizer

  Nutrition release of organic fertilizer slowly, fertilizer efficiency is long, which is the most suitable base fertilizer. Before sowing when turn up the soil, applying them into the soil, which is commonly known as bottom fertilizer, sometimes apply organic fertilizer in the vicinity of the seeds, this is known as seeding- fertilizer. The method is suitable for denser planting crops. 

  This method of fertilization is simple, labor - saving and uniform fertilizer application. But there are also many drawbacks to this approach. Firstly, fertilizer efficiency is low. Generally, more fertilizer is applied in the whole field, but the root can only absorb and utilize the fertilizer around the root system. Secondly, large amount of fertilization can easily lead to the enrichment of phosphorus and potassium nutrients and imbalance of soil nutrients. Thirdly, the fertilizer mobility is low in greenhouse. Heavy fertilization can also increase soil salt concentration.

(2) Concentrated application of organic fertilizers

The concentrated application of commercial organic fertilizers with high nutrient content, generally adopts the method of applying in planting holes or digging ditches, and the concentrated application in the extension part of root system can give full use to its fertilizer effect. But the application is not the closer to the planting hole, the better. the soil becomes better permeability, the roots spread well, and the roots absorb nutrients effectively. In terms of fertilizer efficiency, concentrated application is the most effective for the fertilizer effect of phosphate nutrients. If phosphate nutrients are applied directly to the soil, the available phosphorus components in organic fertilizers are easily fixed by the soil, thus reducing the fertilizer efficiency. There are a lot of available phosphates in the organic fertilizer. In order to improve the fertilizer efficiency, the organic fertilizer should be applied intensively and the fixation of available phosphorus in soil should be reduced.

  Organic fertilizer is not only the ideal basic fertilizer, decomposed organic fertilizer contains a lot of quick effect nutrient, also can be used for additional fertilizer. so we have to choose one type suitable fermentation compost turning machine for the better composting fermentation process and high quality of organic fertilizers. Fertilizer additional application is a kind of nutrient supply during crop growth. The main purpose of the later application of fertilizer is to meet the great need of nutrients in the growth process of crops. To ensure the crop yield, organic fertilizers contains low content of nutrients. When some components are lack in organic fertilizers, appropriate single chemical fertilizers can be applied to supply them.

  In modern agricultural production, many crops are cultivated their seedling under certain conditions and then transplanting in the field. The amount of nutrition needed for seedling cultivation is small, but the deficiency of nutrition cannot cultivate strong seedling, which is not conducive to transplanting and future crop growth. Fully decomposed organic fertilizer, uniform release of nutrients, nutrients overall, is an ideal fertilizer for seedling growth. Generally, 10% fully fermented organic fertilizer is added with a certain amount of peat, vermiculite, and the soil is mixed evenly to be used as the substrate for seedling cultivation.

  

  And in addition, In the protected areas such as greenhouse and plastic greenhouse, more vegetables, flowers and special crops are planted. These crops have relatively high economic benefits. In order to obtain a good economic income, it is necessary to fully meet the various conditions of crop growth and soilless cultivation was often used. Organic fertilizer is added to the substrate to provide nutrients for crop growth. 

During the entire growing period of a crop, a solid fertilizer is added to the substrate at intervals to maintain a continuous supply of nutrients. The application of organic fertilizer can reduce the usage of nutrient solution and decrease production cost. The general formula for nutrient soil cultivation is :0.75m³ turf, 0.13 m³ vermiculite, 12 m³ perlite, 3.00kg limestone, 1.0kg superphosphate (20% diphosphate), 1.5kg compound fertilize, and 10.0kg decomposed organic fertilizer. Different crops varieties can adjust the cultivation formula of nutrient soil according to the growth characteristics and fertilizer need. 

  Organic fertilizer has wide application in the home and abroad for crops, but master the correct application technology is the core in the production of organic farming.
