The present invention relates to a method for producing a composition for use in land application. The method comprises: (a) obtaining a fermentation product by a production process comprising the steps of: (i) treating lignocellulosic feedstock to produce sugar; (ii) fermenting the sugar to produce a fermented mixture comprising the fermentation product; and (iii) recovering the fermentation product from the fermented mixture in one or more stages to produce a concentrated fermentation product and still bottoms; and (b) recovering the still bottoms, the still bottoms comprising organic and inorganic components; and (c) providing the still bottoms for use in a land application. Also provided is a soil conditioning composition for use in land application. The soil conditioning composition contains still bottoms and optionally other components.

Provided is a method of processing stillage from an ethanol production process. The method comprises treating stillage comprising oil, protein, and water upstream of a separation, concentration or evaporation step with at least one coagulant and at least one flocculant, thereby forming treated thin stillage comprising solids which include at least a portion of the oil and protein; and clarifying the treated stillage via a solid/liquid separation process thereby forming clarified stillage and a separated solids phase comprising at least a portion of the solids from the treated stillage.

Disclosed are malt sprouts fraction extracts, their process of preparation and their use as a biostimulant agent.

Molasses based alcohol distilleries generate highly contaminated, dark coloured and foul smelling effluent (bio-methanated spent wash, BMSW, also known as post methanated effluent). While the prevailing practices for treatment of alcohol distillery effluents operate on the premises of liability management, high potassium content of spent wash (ca. 2% w/v in BMSW) offers an opportunity for its utilisation in production of potash fertilizersa major agricultural input. The present invention provides process for potash recovery from BMSW with concomitant environmental remediation of effluent. The process involves pre-treatment of BMSW followed by potash recovery through selective precipitation technique to produce potash fertilizers and activated carbon while generating a relatively benign effluent (>80% remediation). It may further be possible for the alcohol distilleries to achieve ZLD status by incorporating commercially practiced water recovery techniques (viz., multiple effect evaporation/nano-filtration/reverse osmosis etc.) for downstream processing of the process effluent.

A composition for weed control and fertilizer comprising iron hydroxyl ethylenediaminetriacetic acid, humate, microelements, soy hydrolysate, calcium lignin, a natural-based wetting agent, molasses desurgarized solubles, and water, and may further comprise glycerin and/or preservatives, are provided. Methods for weed control and fertilization of plants comprising the steps of providing a composition comprising an effective amount of iron hydroxyl ethylenediaminetriacetic acid, humate, microelements, soy hydrolysate, calcium lignin, a natural-based wetting agent, and molasses desurgarized solubles, and applying an effective amount of the composition to soil or a plant or a weed, are also provided.

The present invention provides a special fertilizer for cut side slope soil remediation in high altitude areas, which is prepared by effectively compounding raw material components of a yak manure-containing compost, an organic micro multi-element fertilizer, a chemical fertilizer, attapulgite powder and sodium alginate under certain conditions. The special fertilizer has obvious effects on the aspects of improving the physicochemical properties of artificial soil at cut side slope wounds in the high altitude areas, increasing the fertilizer efficiency and promoting vegetation restoration.
