Disclosed are compositions that include treated biodiesel glycerin. The disclosed compositions may be utilized as soil-amendments for controlling pests, weeds and for enhancing growth of plants. The biodiesel glycerin utilized in the disclosed compositions may be treated by one or more steps including neutralization, heating, refluxing, condensing, and distilling.

A material for optimizing and maintaining at least one of water, nutrients, biocides, and other protectant or growth supporting chemicals in natural soils by decreasing leaching, evaporation, and volatility through application of agglomerated granules (prills) formed of engineered hydrating particles, a binder, nutrients, and protectants to the soil. Typical application is by applying prills simultaneously with seeds when drilled, broadcast, or otherwise distributed.

A method of fertilizing a plant comprises applying to a plant an effective amount of a composition comprising a product of a salicylic acid, a potassium polyphosphite, a potassium phosphite, and a potassium phosphate. The composition may be prepared by reacting salicylic acid, ammonium hydroxide, potassium hydroxide and/or potassium carbonate, phosphoric acid, and phosphorous acid.

Disclosed is a process of stabilizing spent filter material that comprises mixing the filter media with a dry media to produce a composition having a moisture content that is sufficiently low to retard microbial growth. The composition comprises spent filter media and a dry material, and preferably comprises diatomaceous earth. Soil is treated by adding the composition as a top dressing, soil amendment, or the like.

Aspects of the invention include compositions for controlling plant parasitic nematodes. Compositions according to certain embodiments include a carbon skeleton energy compound, a chelating agent, macronutrients, micronutrients, an ionophore, exotic micronutrients and a plant parasitic nematode antagonist. Methods for using the compositions of the invention to control plant parasitic nematodes and kits having one or more compositions for controlling plant parasitic nematodes are also described.

A pesticide, fungicidal, bactericidal, anti-pathogen or biocidal composition includes at least one biologically inert carrier; and at least one doped component including at least one fixed copper compound doped with at least one compound selected from the group consisting of iron compounds, zinc compounds, magnesium compounds, calcium compounds, and combinations and/or mixtures thereof. In one embodiment, the doped component has a particle size of about 0.5 nm to about 30 microns. A method for the control of pests includes the step of applying to the pests or their growth habitat the aforementioned composition. The method also includes the control of disease in citrus plants caused by vectors such as Psyllid nymphs, by applying the aforementioned composition to their growth habitat in citrus groves.

A method for enhancing or reducing photosynthetic activity, wherein non-toxic pigmented matter is applied to a photosynthetic organism. Depending on the composition of the pigmented matter, the method will have the effect of enhancing, reducing, or inhibiting photosynthetic activity.

A biological product for the purification of water, soil, industrial wastewater from chemicals that are resistant to degradation, such as pesticides and oil, contains a composition of strains of bacteria Pseudomonas putida VKPM B-10997, Bacillus subtilis VKPM B-10999, and Rhodococcus erythropolis VKPM Ac-1882 in a weight ratio of (1-2);(1-2):1. The biological product can further contain sorbent, organic and mineral supplements, and stimulating agents. The biological product can be used for the decomposition of degradation-resistant pesticides and oil and has plant growth stimulating and fungicidal activity.

In some embodiments, the invention provides a unit for delivery of agrochemicals to the roots of a plant comprising: one or more root development zones; optionally, one or more agrochemical zones; and a pesticide; wherein the agrochemical zones are formulated to release at least one agrochemical into the root development zones in a controlled release manner when the root development zones are swelled; and wherein the dry weight ratio of the root development zones to the agrochemical zones in a dry unit is 0.05:1 to 20:1, or wherein the total volume of the root development zones in the unit is at least 0.2 mL when the unit is fully swelled.

A quantum carrier for improvement of soil functions and method of preparation thereof, the method of preparation includes crushing the oyster shell before subjecting to a first high temperature sintering at the temperature of between 800 and 1300 C. for between 1.5 and 2.5 hour, followed by mixing with diatomaceous earth, soil and water to form a liquid oyster shell liquid for liquid sintering at a temperature of between 800 and 1300 C. for between 7 and 9 hours, to give a dimpled or honeycomb-like particle with rough surface, the quantum carrier; the quantum carrier obtained by said method has the function of soil improvement, soil improvement includes self-purification of the soil, degradation of the heavy metals and toxin residues in the contaminated soil, water content increase, oxygen content increase, protein content increase, pH adjustment, pest elimination and promotion of microbial growth.
