Definitions
- the present invention relates to the amendment of soils by calcium inputs.
- Various products are known in the state of the art for soil improvement.
- French patent FR2699916 describes an organic agent for soil amendment based on organic matter, said organic agent containing up to 10% by weight of nitrogen, of phosphorus calculated in the form of P2 05 and of potassium calculates in the form of K2 O, said organic agent having a dry matter content of more than 50%, the organic matter content, relative to the dry matter, being from 15 to 35%.
- Another French patent filed under the number FR2620206 relates to a process for drying limestone or magnesian rock using a chemical reaction initiated by addition and then mixing with a similar product, quicklime.
- the mixing takes place at room temperature and under well-defined conditions.
- the reaction time includes heating of the product with release of vapor 4 as well as the absorption of the water contained in the wet rock by quicklime which is transformed into slaked lime.
- the final mixture product improved in terms of its use is particularly intended for application to acid agricultural soils.
- the object of the invention is to provide a high-performance amendment product obtained by natural base materials, easy to handle and little harmful. It aims in particular to reduce the rate of pollution in the event of incorrect dosage of products.
- the invention relates more particularly to a product for the amendment of soils by calcium inputs, characterized in that it consists of oyster shells having undergone a grinding treatment and optionally a drying treatment, with l exclusion of any treatment likely to modify the chemical composition of oyster shells.
- the product consists of fragments of oyster shells having a particle size between 1 and 10 millimeters.
- the invention also relates to a soil amendment process characterized in that finely divided oyster shells are added.
- the doses of finely divided oyster shells are between 20 kg per 100 m2 for an initial pH below 6, and 5 kg per 100 m2 for an initial pH between 7, 5 and 8.
- the addition of finely looted shells is carried out at least one month before the application of fertilizer or manure.
- the product according to an exemplary embodiment has, according to the origin of the shells, the following composition:
- This carbonate represents a variety of calcium which is particularly assimilable, due to its animal origin.
- Trace elements are all represented, at reasonable rates, compared to those usually present in fertilizers and soil improvers. These substances are also easily absorbed by the soil.
- the product is particularly indicated for its calcium intake, in particular:
- the recommended dose is 20 kg per 100 m 2
- the recommended dose is 15 kg per 100 m 2
- the recommended dose is 10 kg per 100 m 2
- the recommended dose is 7.5 kg per 100 m 2
- the recommended dose is 5 kg per 100 m 2
