Description

Technical field

The present invention relates to an organic soil conditioner based on dried manure.

BACKGROUND OF THE INVENTION

Organic and mineral components are used to prepare horticultural soils and substrates.

Of the organic components, peat is the most widespread, and alternative components (wood fibers, coir, etc.) and various composts (composted bark, composted waste material from greenery maintenance, composted manure, composted by-products in biogas production, etc.) are the most common. Alternative components to peat are used to replace peat and to adjust the physical properties of the cultivation mixtures (especially to increase air capacity). Composts are used to supply acceptable and storage nutrients and their dosage depends on nutrient content and pH. Treated organic fertilizers, such as dried manure, are also used to supply nutrients.

Of the mineral components, overburden soils and subsoil layers are usually used for the preparation of garden soils in proportions of 30 to 80% by volume. For the preparation of organic substrates clays, loess clays and special mineral components (eg zeolites) are used.

For composts, the total nutrient content (CSN 46 5735) is determined for the soil application. Total nutrient contents are also determined for compost and manure treated by drying. Depending on the total nutrient content, the dose of the compost or dried organic fertilizer is difficult to determine in order to achieve an optimal content of acceptable nutrients in the horticultural soil or substrate.

Horticultural composts have a fine structure and do not contain a fibrous component. When used, as components of horticultural substrates, they generally reduce the air capacity of the composition. The essence of the technical solution

The aforementioned drawbacks are eliminated by the auxiliary organic soil substance based on dried manure, which is based on the fact that it contains from 60 to 70% by volume of dried manure as the main component.

In addition to the dried manure, the soil conditioner contains 20 to 30% by volume of dried separated digestate and 5 to 10% by volume of biomass ash.

The basic chemical properties of pH, EC and acceptable nutrient contents according to ČSN EN standards are used for evaluation of components of substrates in terms of their use for soil preparation. The pH values (EN 13037) and EC (EN 13038) and acceptable calcium (EN 13652) are evaluated in the water leachate. The content of acceptable nutrients (main and trace nutrients) is assessed according to EN 13651 in the CAT leaching agent. The content of acceptable trace nutrients may also be determined in the CAT extract. Based on the chemical properties determined in this way, it is possible to determine the optimum dosage of soil conditioner or other components in the preparation of horticultural soils and substrates.

The soil conditioner contains three components. The high content of acceptable nutrients provides dried manure to the soil conditioner. The dried separated digestate reduces the bulk density of the soil conditioner and provides a fibrous component that provides a high air capacity of the prepared soil or substrate. The dried separated digestate also has a high content of acceptable nutrients. To supply acceptable potassium and especially magnesium and calcium, ash from biomass combustion is added to the soil conditioner.

Example of technical solution implementation

Dry manure-based soil composite consisting of 65% by volume of dried manure, 25% by volume of dried separated digestate and 10% by volume of ash from biomass combustion. The optimum dose of soil conditioner for the preparation of horticultural soils and substrates is 15% by volume.

Industrial applicability

The soil conditioner is intended for the preparation of horticultural soils and substrates and for the modification of chemical and physical properties of soils.
