The present disclosure, in various embodiments, discloses hydrothermal methods, hydrothermally modified materials and dried hydrothermally modified materials. Certain dried hydrothermally modified materials can readily releases ionic species such as alkali metal ions (K.sup.+, Na.sup.+), silicate salts, and alkaline earth metal ions (Mg.sup.2+, Ca.sup.2+). Some dried hydrothermally modified materials can readily release aluminum ions and/or silicon, such as in the form of soluble silicates. Such processes and materials are useful, for example in economically preparing potassium releasing fertilizers.

The invention relates to a method for producing sulphur-containing potash granules from fine-particle, potassium-chloride-containing raw materials and elementary sulphur, and to the sulphur-containing potash granules obtained with this method. The method comprises the following steps a) and b): a) mixing a potassium-chloride-containing, fine-particle raw material with a sulphur melt in a quantity of 2 to 30 wt. %, in particular 3 to 25 wt. %, preferably 5 to 23 wt. % and particularly preferably 8 to 20 wt. % in relation to the total amount of sulphur melt and fine-particle raw material, producing a mixture of fine-particle raw material and molten sulphur; and b) compacting the mixture of fine-particle raw material and molten sulphur obtained in step a). The invention also relates to the use of sulphur melts in the production of potassium chloride granules by compacting a potassium-chloride-containing, fine-particle raw material to reduce the pressing force during compacting, and to the use of sulohur melts to improve the mechanical strength of potash granules, containing potassium chloride, in particular potash granules obtained by compacting a sulphur- and potassium-chloride-containing, fine-particle raw material.

An improved method for treating ordinary tap water to create an enhanced water composition for watering plants which can remove fluoride and chlorides from the tap water, and finally, to treat the enhanced water composition to provide a preferred pH level that is ideal for growing plants, and particularly medically grown cannabis, in order to enhance the uptake of certain nutrients for these plants.
