The present invention addresses to the production of an organomineral fertilizer consisting of a mineral matrix, drilling gravel and an organic matrix, algae biomass. Algae are cultivated using drilling gravel suspended in the culture medium together with their ability to grow by absorbing CO.sub.2, and, in the case of cyanobacteria, they fix atmospheric nitrogen in their biomass. The gravel provides a set of additional nutrients present in its composition to the conventional nutritional chemical compounds for algae. In this way, the gravel can be mixed with the culture medium in the cultivation of algae, generating the organic matrix to be formulated and commercialized in the national and international agricultural market as an organomineral fertilizer, and, in the case originating from the organic matrix of cyanobacteria, there is the enrichment with nitrogen obtained biologically, without the high energy expenditure typical of traditional synthetic nitrogen fertilizers. In this way, the present invention enables the disposal with a minimum of environmental impact and constitutes a satisfactory solution for the disposal of gravel for oil E&P.

An agricultural or horticultural fertilizer, and method of making the fertilizer, featuring processed montmorillonite clay and other ingredients for improving plant growth and health. Liquid fertilizers for use in drip irrigation may comprise potash in an aqueous blend, as well as citric acid and humate. The method involves the preparation of a montmorillonite mineral-humate solution, which solution is mixed with other ingredients. In an early step, the montmorillonite and the humate are mixed with water and citric acid, and then blended or mixed over a period of time sufficient for the citric acid to leach the montmorillonite and humate into solution. The solution is then filtered to remove solid mineral residue. The filtered solution is then mixed with Aloe vera and potash to prepare a concentrated liquid.

A dry and solid fertiliser in the form of discreet particles is provided. The particles of the dry and solid fertiliser comprise a homogenous mixture of organic and inorganic materials. The inorganic material comprises at least one of the NPKS nutrients. The organic material comprises a carbon-labile substantially sterile product of organic waste.

An apparatus, method and system are provided to recover constituent components from single use batteries. In particular, the apparatus, method and system may be used to recover zinc and manganese in the form of sulfates from depleted commercial which in turn may be subsequently used for other applications, such as micronutrients and fertilizers.

A method to grow cannabis is described, wherein the method includes providing and treating a source of water, mixing the water with an additive to form a liquid mixture, transferring the liquid mixture to a plurality of cannabis plants grown in a growing medium including a mycorrhiza fungus, and growing the cannabis using a humidity control method, then harvesting the cannabis plants. Trimming and grinding the cannabis along with use of environmental control methods including temperature, humidity, lighting schedules, and carbon dioxide concentrations are also described.
