A fertilizer coating that provides nutrients and/or biocatalysts, as well as added dust control and caking control. The fertilizer coating may comprise a carrier, one or more micronutrient dispersants, and one or more micronutrients. The carrier may be aqueous-based or oil based. The coating may further comprise one or more biocatalysts in an aqueous media.

A process for preparing a polymeric membrane for materials used in crop production comprising: a) providing an aqueous dispersion of a polyurethane or polyurethane-urea elastomer comprising segments formed from the copolymer segment of Formula I
A.sup.1-[Y.sup.1].sub.n-L-[Y.sup.2].sub.q-A.sup.2  Formula I
wherein A.sup.1 is an end capping group; A.sup.2 is hydrogen or an end capping group; each [Y.sup.1].sub.n and [Y.sup.2].sub.q is independently selected from a polyether macrodiol, polycarbonate macrodiol, polyester macrodiol, and wherein at least one of [Y.sup.1].sub.n and [Y.sup.2].sub.q is a polyester macrodiol; L is a divalent linking compound independently selected from urethane, urea, carbonate, ester, and phosphonate; n is an integer of 2 to 50; q is an integer of 2 to 50; and b) spraying the aqueous dispersion onto materials to be used in crop production to form a polymeric membrane on the materials.

A method for improving seed planter flowability comprising: admixing one or more seeds with a flow-aid composition comprising a modified starch, a non-modified starch, or a mixture thereof, wherein said flow-aid composition optionally comprises a mineral earth lubricant. A plurality of seeds comprising said flow-aid composition. A flow-aid composition comprising a modified starch, a non-modified starch, or a mixture thereof, wherein said flow-aid composition optionally comprises a mineral earth lubricant and further wherein said flow-aid composition is (i) free-flowing, and/or (ii) reduces seed agglomeration relative to one or more seeds admixed with talc, graphite, or a mixture thereof.

The disclosure relates to fertilizer coating compositions and methods for making thereof. The fertilizer coating comprises a decarboxylated rosin acid (DCR) component, optional bitumen and other additives. The DCR has a Kb value of 25-90, a density of 0.9 to 1.0 g/cm.sup.3 at 20° C., an aniline point of 3-40° C., and an acid value of <50 mg KOH/g. The fertilizer coated with the coating composition has a reduction in dust level of >25% after 2 weeks of aging compared to a fertilizer not having the coating composition disposed thereon, according to Dust Level Measurement Test.

A method for single-grain application of seed by means of an agricultural sowing unit with at least one sowing element (200), which has a metering device (210) and a single grain-laying device (220), for the single-grain depositing of the seed along or within a seed furrow (310) arranged in the soil (300). A single grain (320) of seed is deposited along or within the seed furrow (310), adjacent to individual grains (320) of seed at a distance (l.sub.1) that can be selected or adjusted as required. A selectable or predetermined number (x) of seed capsules (100) is assigned to each single grain (320) of seed, whereby the seed capsules (100) are placed adjacent to the assigned single grain (320) along or within the seed furrow (310), and the active or stimulating substances (140) contained in the seed capsules (100) are released to support the associated single grain (320).

A combined microalgae and mycorrhizal fungi granular formulation includes a microalgae inoculant combined with a mycorrhizal fungi inoculant with demineralized water to maintain moisture and applied to carrier granules such as a natural clay-based or mineral-based material. The coated granules are dried and may be applied to agricultural areas in dried granular form.

The present disclosure concerns fertilizer particles comprising calcium nitrate and potassium nitrate. It is found that fertilizer particles comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate can be produced by melt granulation. Due to undercooling problems, such particles were not expected to be suitable for industrial production by melt granulation. However, the present disclosure provides a composition which forms a low viscosity melt with short solidification time. This was successfully achieved by reducing the water content of a fertilizer melt comprising 43 to 47% w/w calcium nitrate and 46 to 54% w/w potassium nitrate to less than 3% w/w of the melt.
