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.

Kits for seed pre-germination are included. The kit includes a storage vessel and a seeding composition. The seeding composition includes plant seeds, a porous granular material, and a polymer-coated fertilizer. Methods for preparing seeds for germination are also included. The method includes combining the seeding composition with water in the storage vessel and sealing the storage vessel, such that little to no aeration is permitted during subsequent storage of the same.

The present invention concerns a Portland cement-free porous rigid mineral substrate made of alkali-activated pozzolans, a method for preparing the same, and use of said substrate to optimize plant germination and growth.

Described herein are methods, compositions, products, and processes that utilize bioceramics in traditional agricultural and hydroponic systems. The bioceramics are utilized in powder form, as films, as aerosols, as water based treatment systems, or in solid forms. The methods and bioceramic compositions described here are also used for growing a Cannabis plant. One or more cannabinoids within the plant can be used in therapeutic compositions for the treatment of glaucoma, AIDS wasting syndrome, neuropathic pain, cancer, multiple sclerosis, chemotherapy-induced nausea, and certain seizure disorders.
