The present disclosure describes a composition including a sulfopolymer, and one or more agrochemicals. The composition exhibits increased rainfastness as compared to the same composition without the sulfopolymer. The present disclosure also describes methods of making and using such emulsion formulations in agriculture.

A method of reducing dust formation and/or caking in fertilizer or other particulates. The method comprises coating the fertilizer or other particulate in a coating comprising vacuum tower asphalt extender (VTAE). The VTAE may be a non-distilled fraction of vacuum distillation of used automotive and/or industrial oil. The VTAE may not be asphalt or bitumen, although the coating may further comprise bitumen.

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.

An anticaking agent having a coating and a mineral matrix of a coarse mineral and a fine mineral is described. A method of making the anticaking agent is disclosed, as well as a method of applying the anticaking agent to a hygroscopic fertilizer to reduce caking in high temperature and high humidity environments. The coarse mineral may be a diatomaceous earth.
