Abstract: The present invention relates to a process for inhibiting, at least in part, nitrification activity of ammonium-containing fertilizers (a1) and/or of ammonium-producing fertilizers (a2), which process comprises the steps of: a) Applying to soil and/or to foliage a nitrification inhibitory amount of one or more compounds (b) that are selected from the group consisting of (b1) polysulfides and/or (b2) thiosulfates and/or (b3) hydrosulfides; b) Wherein the one or more compounds (b) are applied simultaneously with, before or after the fertilizers (a) are applied to the soil and/or to the foliage such that the compounds (b) are in direct contact with the ammonium-containing fertilizers (a1) and/or the ammonium-producing fertilizers (a2); c) Wherein the one or more nitrification inhibiting compounds (b) are applied in an amount: i. such that the ratio (w/w) of "total protectable nitrogen"over "sulfur from compounds (b)" is at most about 8:1, preferably at most about 7.5:1, more preferably at most about 7:1, and/or, ii. corresponding to a soil level of S (sulfur) that is between about 50 and about 300 ppm, preferably between about 75 and about 300 ppm, more preferably between about 100 and about 250 ppm; and d) Wherein compounds (b) are different from compounds (a).

Abstract: The present invention relates to liquid fertilizers comprising water; a first fertilizing ingredient dissolved in the aqueous liquid; a solid suspended in the aqueous liquid, wherein the solid comprises calcium; and a polysaccharide rheology modifier; characterized in that the suspended solid has a Dv(25) of 5 micron or more and a Dv(75) of 100 micron or less as determined by laser diffraction. The present invention further relates to methods for producing said liquid fertilizers and the use thereof for fertilization through side dress, soil injection, spray (soil and/or foliar) or fertigation application, preferably spray or fertigation application.
