Do I need to add superphosphate to compost?

Superphosphate is a complex mineral fertilizer with a high content of phosphorus, nitrogen, sulfur, potassium, calcium and other trace elements. Its use allows for better development of the root system and faster fruiting in all cultivated plants without exception. This fertilizer is produced in various forms. It can be powdery, granular, and can also vary in composition. There are several ways to add superphosphate to the soil: for digging in the fall or early spring, when planting - directly into the hole in the form of an aqueous solution for irrigation. It is also possible to apply it through compost.

Why fortify organic supplements with mineral

Compost is a compound organic fertilizer obtained as a result of overheating of garden and household waste with their further processing by soil microorganisms. Good humus is quite capable of replacing manure or other organic fertilizers to feed your pet in the garden and vegetable garden. In addition, the resulting humus is a balanced organic supplement, without excess nitrogen.

And in order to enrich the resulting mass with the necessary nutrients, you can use mineral supplements. Superphosphate will be an excellent source of phosphorus.

Phosphorus fertilization will ensure good root development and will also make the trees more protected from pests.

Keep in mind that the application rate for this supplement is different for each plant.

Which fertilizer is better to choose

The best way is to add simple superphosphate to the compost, since this particular variety is poorly soluble in water and contains phosphorus, which is difficult for plants to access. It is necessary to apply top dressing when laying the compost mass, sprinkling the layers with powder, at the rate of 10 grams of a mineral additive per 10 kilograms of organic matter. Further, the mass ripens as usual, and at the exit you can get excellent humus, rich in easily digestible phosphorus compounds.

Double superphosphate is also commercially available. It is richer in easily assimilable phosphorus and almost does not contain hardly soluble elements. It is pointless to put such a mixture in compost, it is easier to add it to the soil when planting plants or through watering.

Thus, you have received an answer to the question whether superphosphate can enrich compost. And the answer is yes. Is a phosphorus supplement an indispensable element, without which humus will not ripen? No, it's not. The choice of whether to cook humus with your own hands or to do with other organic dressings remains with the summer residents, as well as whether to add minerals in addition.
