How to mix organic fertilizer with soil?

The difference between organic fertilizer and nutrient soil: it can be understood that organic fertilizer is organic fertilizer, and nutrient soil can be prepared with organic fertilizer. In the application mode, organic fertilizer is the best as base fertilizer, and it can also be used as seed fertilizer, seedling fertilizer and even soilless culture soil, and of course it can also be used to prepare nutrient soil. How to prepare nutrient soil with organic fertilizer: ① Take field soil as the main material, the ratio of field soil to organic fertilizer is (8:2)~ 6:4, and the bulk density of the prepared nutrient soil is about1g/cm2; ② Add a part of peat soil into the field soil, and then add a certain amount of organic fertilizer. The ratio of peat soil to organic fertilizer is 6: 3: 1. The prepared nutrient soil is loose, the bulk density is about 0.8g/cm, and it has good water absorption, heat absorption and fertilizer conservation performance. (3) Use peat and vermiculite instead of vegetable soil to prevent the germs possibly carried by vegetable soil from harming seedlings and spreading to other vegetable fields. The ratio of peat to vermiculite can be 5:5, and organic fertilizer or inorganic fertilizer can be added. This kind of nutrient soil is loose, with a bulk density of about 0.25g/cm, and has good water absorption, heat absorption, fertilizer retention and ventilation.
