A process of biodegradation of hydrocarbons using a plant growth promoting rhizobacteria (PGPR) consortium mixed with the oily sludge, The PGPR consortium is created by inoculating a nutrient broth with pure culture of isolated bacterial strains of Bacillus pumilus, Bacillus subtilis, Pseudomonas putida and Exiguobacterium at Optical Density 1 at 660 nm and bacterial density of 10.sup.6 cells/ml, and incubating the inoculated nutrient broth in a shaker incubator for forty-eight to seventy-two hours at 150 rpm.

Solvents useful with thiophosphoric triamide urease inhibitors, that provide stable solution of a thiophosphoric triamide, such as for distribution (in low or high concentrations) onto a fertilizer or other liquid or solid material that contains urea.

A method for fabricating a dry composition is disclosed including combining a solid carbonate or a solid bicarbonate compound, a solid acid yielding compound, a biostimulant, and a plant nutrient. The dry composition may be processed into a tablet, dry powder, meal, or pellets and produce effervescence when a liquid, such as water or a water-based liquid is mixed with the dry composition.

The invention relates to a conditioning agent for reducing water absorption and dust formation of a particulate fertilizer, comprising 10 to 50 weight % of wax, 40 to 90 weight % of mineral oil and 1 to 15 weight % of a resin being mineral oil-soluble and miscible with wax and mineral oil, wherein the agent further comprises 0.1 to 1 weight % of a viscoelastic elastomer selected from the group of polyisobutylene and styrene-isoprene-styrene block copolymer which is soluble in mineral oil and has an average molecular weight of 30.000 to 5.000.000. The invention further relates to a particulate fertilizer composition, preferably a urea-ammonium sulfate (UAS) fertilizer, a urea fertilizer or a calcium nitrate fertilizer, comprising a particulate substrate, preferably an hygroscopic fertilizer, preferably a nitrogen-containing fertilizer, and 0.05 to 2 weight % of said coating thereon for reducing moisture uptake and dust formation of said fertilizer.

A system and method for providing fertilizer for crop production in an aqueous solution comprising nano-sized fertilizer particles, which are free of any chemical side chain and free any micelle to protect the nano-sized particle from re-agglomeration, suspended therein for improved uptake by the population of the crop.

Fertilizer compositions are provided, where a fertilizer composition includes: an inner portion including a nitrogen containing material; and an outer portion covering the inner portion, the outer portion including a release agent (e.g. HTC, BR).
