  • ash;
  • sodium;
  • phosphorus oxide;
  • potassium.

The amount of these components may differ depending on the reservoir and bottom composition. Boron, copper and zinc can be included in sapropel in small amounts. The formation of fertilizer is influenced by the surrounding ecosystem.

Useful properties of sapropel

Top dressing has a number of advantages over other types of fertilizers:

Sapropel is actively used by gardeners for all plants. It can be applied under cereal plants, as well as under vegetable crops. You can also fertilize fruit trees or bushes. It is important to correctly assess the acidity of the soil before fertilizing and purchase the required brand.

How and where is sapropel obtained?

There are several ways to extract sapropel on an industrial scale.:

  • using hydraulic mechanisms;
  • using grabs and excavators;
  • screw technique;
  • point vacuum and suction;
  • scraper-suction method;
  • using a locking cylinder.

Special large-sized machines called dredgers are used. Lake humus is obtained in large quantities and then processed by special devices. Preliminary cleaning of stones, removal of excess moisture is required.

Sapropel extraction by mini hand dredgers

Sapropel can be obtained by yourself. This is done in the shallows of a wetland. To set the fertilizer, you need to take a pitchfork. They need to be modified. A special wire is put on them, from which a mesh is formed. The transverse diameter of the wire must be at least 0.2 millimeters. The sapropel does not lie at great depths, and a large amount of material can be dug out with a pitchfork with a wire. For mining, it is necessary to choose ecologically clean areas, since sapropel can absorb heavy metals and other harmful components.

You can mine sapropel using mini dredgers. This is a device, the principle of which is no different from its larger counterpart, but the scale of production is smaller. The weight of the machines ranges from 20 to 200 kg. In one day of work, you can collect sapropel on a small piece of land. The cost of sapropel obtained in this way is 10 times less than the finished purchased material in stores.

Special preparation of sapropel before use

If sapropel is mined by hand, then after raising humus and humus from the bottom of the reservoir, it is necessary to clean the material and also dry it. The action is performed in any case, but with independent mining, a sieve is needed for this to sift out excess stone scrap. Then the resulting material must be dried. This process takes the longest time intervals.

Material from the state of viscous clay and humus turns into powder. The preparation process, namely drying, is necessary to preserve the useful properties of the material. If the sapropel is not dried, it starts to rot, and the ammonia vapors in its composition kill all useful substances.

The main uses are as follows:

  • adding the product to the soil or compost heap with further mixing;
  • adding to acidic soil to neutralize its indicators;

Positive aspects of the sapropel composting process

Composting is the process of mixing sapropel with humus. Such a technique is used to improve the quality of fertilizer, rapid assimilation by the soil. It is the nitrogen-containing components of the composition that respond favorably to mixing with humus. The following scheme is used as a proportion: two parts of sapropel to one part of humus or manure. All material is laid in layers, it matures within three months.

In addition to manure and sapropel, you can add peat, potassium-phosphorus fertilizers. In finished form, such fertilizers contribute to rapid growth, and all proportions of the components are observed in them. Plants will be more resistant to weather conditions.
