A fertilizer composition is provided that includes sulphur and rock phosphate. The fertilizer composition can be a controlled release fertilizer that includes elemental sulphur, a rock phosphate, and a swelling material. The rock phosphate is present in the fertilizer composition in low amounts, e.g., 5% by weight or less. The fertilizer composition can be produced by mixing molten elemental sulphur with rock phosphate and cooling the mixture.

The present invention relates to the use of a fructooligosaccharide (FOS) comprising from 2 to 10 monosaccharide units, as an elicitor of the mechanisms of absorption of mineral elements from the soil, and of the defense mechanisms against pathogens. It also relates to a fertilizing and biostimulating composition containing these fructooligosaccharides, and to the use thereof in a method for treating crop plants.

A composite particle and a population of particles comprising a water-insoluble polyphosphate composition, methods of producing, and methods of using the same are provided. The polyphosphate composition may comprise at least one alkaline earth metal selected from calcium and magnesium and optionally at least one nutrient ion selected from the group consisting of potassium, ammonium, zinc, iron, manganese, copper, boron, chlorine, iodine, molybdenum, selenium or sulfur.
