This invention relates to processes and systems for converting fresh food waste into nutrient rich hydrolysates and particulate compositions. The invention also relates to the hydrolysates and compositions useful, for example, as fertilizers, feedstock or other nutrient supplements.

A facility secondary NO.sub.3.sup. salinized soil modifier and a modification method are disclosed. The present invention involves the preparation processes of two biological soil modifiers A and B and application methods thereof, which are specifically described as follows: (1) soil modifier A.: solid, obtained by microbial fermentation with straw powder and rice bran and the like as raw materials. C/N between 30-50, applied by uniformly mixing at 1-1.4% by mass with facility ploughing soil, co-culturing at 35-50 C. for 5-7 days, and then returning to fields; and (2) soil modifier B: liquid, subjected to salt tolerance acclimation to have effective microbial populations, and used in the crop growth period. Based on the microbial techniques, the present invention can improve soil structureness, enhance microbial activity and promote biological immobilization on inorganic nitrogen in soils, significantly increasing the facility cultivation crop yield, and improving the product quality.

A method to manufacture native soil flowable fill includes hydro excavating native soil to form a hole at a first excavation, and transferring the native soil from the first excavation to a mixing tank. The method also includes adding a pozzolan component, cement and water to the mixing tank, mixing the native soil in the mixing tank with the added pozzolan component, cement and water to form the native soil flowable fill, and transferring the native soil flowable fill back to the first excavation and into the hole.

A material for optimizing and maintaining at least one of water, nutrients, biocides, and other protectant or growth supporting chemicals in natural soils by decreasing leaching, evaporation, and volatility through application of agglomerated granules (prills) formed of engineered hydrating particles, a binder, nutrients, and protectants to the soil. Typical application is by applying prills simultaneously with seeds when drilled, broadcast, or otherwise distributed.

Multi-functional biological compositions are provided for reducing hydric stress and promoting growth in cultivated plants, for use as an inoculant, as a soil conditioner, as a biostimulant, for phosphorus solubilization and for bioremediation in agricultural areas. In particular, compositions containing mixtures of additives and excipients are provided having at least 2 (two) or more species of Bacillus or two or more strains of a single species, or the mutants thereof, concomitantly with additives and excipients, in biological compositions with properties for reducing hydric stress and promoting growth in cultivated plants, for use as an inoculant, as a biological soil conditioner, as a biostimulant, for phosphorus stabilization and for bioremediation in agricultural areas, added to the coating/encrustation used in industrial or non-industrial seed treatment, applied in furrows, using a guided boom or by other application means.

Embodiments of the present disclosure provide compositions and methods for increasing nutrient uptake by plants and for effecting soil remediation. Embodiments of the composition and methods comprise a hydrogel bead, a microbial consortia, and a fungi, and can additionally comprise an excipient for administration of the hydrogel bead comprising the microbial consortia and the fungi, one or more seed, water, one or more nutrients, and combinations thereof. Such composition and methods have broad application to reduce fertilizer requirements and use, and to increase plant nutrient access and uptake. The composition and methods have additional application to remediate contaminated mediums such as soil contaminated with chemicals, petroleum, and explosives.
