A process for production of anaerobic digestate based organic fertilizer includes combining anaerobic digestate and one or more grain by-products to create a combination of anaerobic digestate and one or more grain by-products. The combination of anaerobic digestate and one or more grain by-products is processed to yield the pH adjusted anaerobic digestate based organic fertilizer product.

A biologically pure phosphate solubilizing plant growth promoting rhizobacteria (PGPR) XSB375 was isolated from canola rhizosphere and identified as Bacillus firmus is provided herein. The PGPR is capable to solubilize phosphate that enhance plant available phosphorous. The PGPR XSB375 enhances seed germination, early emergence, plant vigor, root and shoot growth, and higher crop yield. This increased crop growth, development and yield is attributed from not only the greater phosphate solubilization making more available phosphorus to plant but also making other essential plant nutrients more available to the plant and the like. The application of this phosphate solubilizing PGPR can be done as liquid suspension or solid materials using onto soil, potting mix, seeds, seed pieces, seedlings, foliage, carrier materials, roots and planting soil.

A method for fabricating a dry composition is disclosed including combining a solid carbonate or a solid bicarbonate compound, a solid acid yielding compound, a biostimulant, and a plant nutrient. The dry composition may be processed into a tablet, dry powder, meal, or pellets and produce effervescence when a liquid, such as water or a water-based liquid is mixed with the dry composition.

An apparatus for recovering nutrients or water from digestate comprises one or more solid-liquid separation units, an ammonia stripping device, and a gas scrubbing unit. In a process, digestate is separated into a solids portion and a liquid portion. Ammonia is stripped from the liquid portion and converted into an ammonium salt solution which may be sold or used as, or blended with, a fertilizer product. Optionally, at least part of the remaining liquid portion may be concentrated to produce brine. The brine is mixed with the solids portion. The mixture may be dried and used as, or blended with, a fertilizer product. Optionally, a least part of the remaining liquid portion may be re-used as dilution water in a digester. A solids portion of the digestate, and one or both of an ammonium salt solution and a brine, may be used as fertilizer without thermal drying.
