Organic fertilizer is applied in clay, which can improve the aeration of the soil(162 cell propagation trays wholesale). When applied in sand, it not only increases the organic matter of the sand, but also improves the water retention performance. Organic fertilizer adds organic matter to the soil, which is beneficial to the life of soil microorganisms and makes the soil microorganisms flourish(2.5 inch square plastic pots). Pine seedlings consume 93.7% and 60.9% more nitrogen and phosphorus than barley.

In addition, when the seedlings are harvested, they must be dug out of the soil together with the main root system, often with soil tufts(200 cell propagation trays wholesale). Organic fertilizer contains a large amount of organic matter, which has good soil improvement effect and long fertilizer effect, which can be maintained for 2-3 years(13cm plastic grow pots). After harvesting the farmland, more crop roots are left in the soil, which can be used as base fertilizers and top dressings, adding some organic matter to the soil.
(best plastic v11 nursery pots manufacturers netherlands)Organic fertilizers produce organic acids when they decompose, and can decompose inorganic phosphorus: organic matter helps the soil to form agglomerate structure(112 cell propagation trays wholesale). These functions played by organic fertilizers are not found in mineral fertilizers, so it is to increase soil fertility, improve seedling quality and An indispensable fertilizer for qualified seedling yield(5 gallon plastic nursery pots). The effect of fertilization on seedling quality is significant.
granular fertilizer is also called granular fertilizer(288 cell propagation trays wholesale). It is made of ammonium sulfate, calcium superphosphate, potassium sulfate or other potassium salts, combined with dried and crushed peat soil and heated(14cm plastic grow pots). Because the fertilizer nutrients are absorbed by the peat humus colloids, which reduces the soil rounding, improves the fertilizer efficiency and lasts, cannot be used in combination with alkaline fertilizers such as lime and grass ash.(best plastic v11 nursery pots manufacturers netherlands)
Compound fertilizer is also called multi-quality fertilizer or diversified fertilizer(20 cell propagation trays wholesale). Fertilizer contains two or more chemical nutrients, such as ammonium phosphate contains two elements of nitrogen and phosphorus; potassium nitrate contains two elements of nitrogen and potassium: ammoniated calcium superphosphate contains two elements of phosphorus and nitrogen(bulk buy plastic plant pots). Use alkaline fertilizers such as lime at intervals of several days.
(best plastic v11 nursery pots manufacturers netherlands)Now it can be used to make various types of compound fertilizers with rat, soluble (soluble phosphoric acid and water-soluble phosphoric acid) and water-soluble potassium(24 cell propagation trays wholesale). Potash fertilizers include potassium chloride (physiologically acidic) and potassium sulfate (physiologically acidic). Inorganic fertilizers are also called chemical fertilizers or mineral fertilizers(4 inch plastic pots bulk). Most of them are industrial products and do not contain organic matter.
The content of nutrient elements is high(plant start trays wholesale). The main components can be dissolved in water or easily become components that can be absorbed by seedlings. Inorganic fertilizers are quick-acting fertilizers, such as nitrogen, phosphorus, and potassium fertilizers(98 cell plug trays). Although the active ingredient of this compound fertilizer is water-soluble, it dissolves slowly and has the effect of being able to be used by seedlings for a long time.(best plastic v11 nursery pots manufacturers netherlands)
First, it must be used together with organic fertilizers such as compost and green manure(4 cell propagation trays wholesale). second, compound fertilizers are water-soluble fertilizers, but top dressings cannot be used in the later stages of seedling growth to prevent longevity; third, for Physiologically acidic and neutral reaction compound fertilizers, the nutrient leaching is less in the soil filling(polystyrene plug plant trays), because they contain ammoniacal nitrogen and water-soluble phosphoric acid.
