Described herein are compositions and methods relating to functionalized sands or soils.

A device and a method for breeding blueberry-specific mycorrhizal fungi. The device includes a container, where a bottom of the container is laid with perlite to form a perlite layer; an absorbent cotton is arranged on the perlite layer; a hole for planting is provided in the absorbent cotton and blueberry tissue culture seedlings or moss seedlings are placed in the hole; and a spore transfer solution is provided around the blueberry tissue culture seedlings or moss seedlings. When used as a bacterial fertilizer for inoculation in the field, the pieces of absorbent cotton are buried directly around the blueberry roots; while used for research, one of the pieces of the absorbent cotton is washed with sterile water and filtered with a filter paper to obtain mycorrhizal fungi spores.

A horticultural growth medium includes a filler and a binder. The binder is a moisture-cured, isocyanate-terminated quasi-prepolymer made from an organic polyisocyanate that includes a large proportion of 4,4-diphenylmethane diisocyanate. This binder system provides excellent curing properties and imparts excellent physical properties to the growth medium.

Provided is a cultivating material composition including a cultivating substrate and a bio-cellulose film, wherein the bio-cellulose film is in contact with the cultivating substrate, such that highly increased yield and quality of crops, a shorter harvest period, less water and nutrient sources, and low cost can be achieved.

The present invention relates to a stable humus-water storage hybrid comprising an organic fertilizer consisting of lignite treated in an oxidizing and ammoniating manner and at least one water-storing component selected from materials of mineral or organic origin, the proportion of the organic fertilizer amounting to 0.5-99.9 vol. %, preferably 1.0-90.0 vol. %, and the proportion of the at least one water-storing component amounting to 0.1-99.5 vol. %, preferably 10.0-99.0 vol. %. The invention also relates to a method for producing the stable humus-water storage hybrid and to the use thereof as a plant substrate, an additive for planting soil and an additive for soil.

A system for hydroponic plant growth is disclosed. The system includes a semi-enclosed container, wherein the semi-enclosed container includes a floating sheet. The floating sheet includes a plurality of first openings, wherein the floating sheet is adapted to be placed on surface of nutrient solution. The semi-enclosed container also includes a plurality of containers. The plurality of containers includes a plurality of second openings. The plurality of containers is adapted to be received into the plurality of first openings of the floating sheet. The semi-enclosed container also includes a plurality of air stones, configured to be operatively coupled to an air pump. The plurality of air stones is configured to supply a pre-determined amount of air into the nutrient solution via the air pump.

The present invention relates to an organic soil builder, conditioner and/or biofertilizer, and to the production method thereof, which organic soil conditioner and/or biofertilizer has an organic base that allows the availability of nutrients in the soil to be increased for use when the plant requires, or the recovery of degraded soils. The method of the invention uses any type of animal waste sludges together with dry matter and granulated minerals. This mixture is fermented for 40 to 210 days, thus obtaining the organic soil builder, conditioner and/or biofertilizer of the invention.
