Embodiments provide inorganic mineral chelated compositions, cobalt compounds and compositions, and treatment compositions, and methods of making and using them. Mineral chelated compositions and cobalt compounds have been shown to improve plant health, plant emergence, crop yield, and plant resistance to disease and drought. The compositions described herein can be applied directly to seeds, soil, or plants, or they can be incorporated with existing agricultural treatments and processes, reducing cost and time for farmers to implement the methods described herein. Accordingly, the compositions can be used as a seed treatment, or they can be broadcast on soil, tilled in soil, placed in-furrow, mixed with other fertilizers or chemicals, side-dressed in the field, used as foliar treatments, or combinations thereof. Such methods provide valuable micronutrients in a highly bioavailable form to plants and soil.

A treated biochar comprising a porous carbonaceous particle that has been treated and mixed with a media containing a mineral solubilizing microorganism, whereby the porous carbonaceous particle after mixing has retained the mineral solubilizing microorganism.

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.

The present invention refers to an industrial process for obtaining an agricultural composition formed by association of one or more species of Bacillus spp., of Lactobacillus spp. and of Pseudomonas, the process for induction of exudates/metabolites, as well as the application thereof in the manufacture and in the increase of the efficiency of phosphate fertilizers of mineral, organomineral and organic origin. Surprisingly, the agricultural composition used in the fertilization industry increases the availability of macro and micronutrients to the plants with agricultural interest, such as soy and corn. Finally, both the use of the agricultural composition in the fertilizers industry as the application of the product in the field potentialize the greater availability of essential nutrients for the development of the cultures.

Primary leachate is used as a plant growth stimulant. A fermentation medium is fermented with a microbial culture in a bioreactor to produce a primary leachate comprising microorganisms derived from the microbial culture and/or naturally occurring microorganisms. The primary leachate is isolated from the bioreactor, diluted with water, and used to irrigate plants to reduce bacterial diversity and stimulate beneficial microorganisms in the rhizosphere around the plants. The fermentation medium may be organic waste, preferably food waste. A secondary leachate may also be used as a plant growth stimulant. The primary leachate is used to culture black soldier fly larvae with a substrate in a secondary processing bioreactor under suboptimal culture conditions, thereby producing secondary leachate. Melanin is extracted therefrom by acid precipitation. The secondary leachate is then diluted with water and used to irrigate plants, reducing bacterial diversity and stimulating beneficial microorganisms in the rhizosphere around the plants.

A phosphate fertilizer as described contains a blend of finely ground sulfur component, swelling agent and rock phosphate (for example, apatite). Preferably, the swelling agent is bentonite. The sulfur component, swelling agent and rock phosphate raw materials are preferably present as particles of less than about 500μ in size, more preferably between about 400-200μ, but more than 100μ. The sulfur component and swelling agent may be combined together before sizing as a composition of about 85 wt % sulfur sublimed onto/into or melted together with about 15 wt % bentonite. These components are present in the phosphate fertilizer at about 10 wt % for the sulfur, at about 5 wt % for the swelling agent and about 80 wt % for the rock phosphate. In addition, when the blend is pelletized, a granulation aid, like lignin, molasses, etc., is also present at about 5 wt % of the blend.
