Calcium silicate hydrate nanoparticles are combined with ammonia control materials (e.g. alum, aluminum chloride, ferric chloride, ferric sulfate, and/or sodium bisulfate) to create a phosphorus-binding composition. In the preferred embodiment, the composition is applied to poultry litter, poultry bedding or other non-aqueous substrates that are at least partially comprised of animal manure. The composition binds with phosphorus to at least reduce the amount of phosphorus in runoff water or in leachate from fields fertilized with treated manure. The combining of the calcium silicate hydrate nanoparticles with the ammonia control products has a surprising and unexpected result. The calcium silicate hydrate-ammonia control material mix reduces soluble phosphorus more than either component of the mix alone.

The present application relates to an iron impregnated biochar and its use as a fertilizer. The iron impregnated biochar of the present application has a ratio of iron (III) to iron (II) ranging from 5:1 to 10:1. The biochar may be produced by a method including treating the biomass with an iron (II) ion solution, pyrolyzing the iron (II)-treated biomass in an oxidative environment and recovering the biochar product from the pyrolyzed iron (II)-treated biomass.

Disclosed herein are soil amendments, generally in the form of coated perlite compositions, as well as methods of making and using the same. The disclosed compositions, methods, and systems provide for various beneficial enhancements to plants growth and soil health, and may decrease costs, for example by avoiding the need for multiple treatments. The presently disclosed compositions, methods, and systems also aid in prolonging release of plant nutrition into the soil (including silica), enhancing aeration, water retention, and drainage, resisting soil compaction, providing for pest and insect control, etc. In many embodiments, the disclosed coated perlite composition is a sterile composition, that is lightweight, and has a low dust content, which may provide for efficient and low-cost handling and transport of products comprising same. The disclosed coated perlite compositions comprise perlite particles having a coating of a mixture of diatomaceous earth phosphorous and may also include one or more of nitrogen, phosphorus, and potassium in the coating.
