    Abstract: Soils are fertilized by a method in which ammonium syngenite (NH4)2SO4.CaSO4.H2O or a mixture of finely divided ammonium sulfate, calcium sulfate, calcium nitrate, calcium chloride and/or dicalcium phosphate is applied to these soils, as a slow-acting nitrogen fertilizer, with the proviso that the molar ratio of Ca to SO4-- in the mixture is 1:2+/-10%.

    Abstract: Prodn. of compact granular prods. contg. (NH4)2SO4.CaSO4.H2O (I) is effected by compressing a mixt. of (NH4)2SO4 and CaSO4 with a particle size of less than 0.5mm in the presence of 0.9-3.5 moles of H2O per mole of (NH4)2SO4, provided that not more than 1.5 mole is present as free H2O. The CaSO4 is used in hemihydrate form. The mixt. is compressed in a double-roll compactor and then broken up into 1-5mm pieces. When gypsum (CaSO4.2H2O) is used as part of the CaSO4, the prod. is pref. stored at 40-100 deg.C..
