Claims17
A method for obtaining a disaggregable granulated calcium and/or magnesium and potassium fertilizer, characterized in that it comprises the following sequence of steps:
- i. choosing sources of calcium and/or magnesium and potassium, wherein at least one source of calcium and/or magnesium is in the chemical form of oxide and/or hydroxide of said calcium and/or magnesium;
- ii. hydrating the at least one source of calcium and/or magnesium in the chemical form of oxide and/or humidifying the at least one source of calcium and/or magnesium in the chemical form of hydroxide, and keeping the at least one source of calcium and/or magnesium hydrated and/or humidified having a humidity of from 5% to 30% by weight and resting for at least 24 hours, wherein the resting comprises periodic homogenization when necessary;
- iii. mixing the sources of calcium and/or magnesium of step ii among themselves;
- iv. granulating;
- and
- v. drying,
- wherein the sources of potassium are added to the sources of calcium and/or magnesium in step ii, iii or iv.
