The present disclosure provides a method of increasing the concentration of K.sub.2O in an aqueous solution. The method comprises reacting potassium sulfate with an acidic compound to yield a product that includes potassium hydrogen sulfate. The product can be used to supplement crops in need of potassium. The product can also have other nutrients added to it, depending on the desired end use. Advantageously, these products increase yield as compared to prior art products.

A stabilized ammonium humate mixture including an amount of humic acid between about 7.0% to about 10% of the mixture and an amount of ammonia between about 1.0% to about 14% of the mixture, where the remainder of the mixture is water. The stabilized ammonium humate mixture has a pH between about 9 to about 11.

The present invention provides a method for reducing plant water stress which comprises contacting plants with dry milled fibre, particularly wheat fibre and pea fibre. Said contacting is carried out in a manner selected from the group consisting of coating seeds with a mixture comprising dry milled fibre, pelletizing seeds with a mixture comprising dry milled fibre, applying a mixture comprising dry milled fibre in the form of granules, and applying a mixture comprising dry milled fibre in the form of tablets. Prior to said contacting, dry milled fibre is admixed with soil for plants, and the resulting mixture may optional comprise further additives such as fillers, binders, inert powders, colouring agents, fertilizers, fungicides, growth hormones, or microorganisms for inoculation.

There is provided herein a process for the compaction of Polyhalite with a Potassium salt, wherein said process comprising: mixing a feed of polyhalite with a feed of said Potassium salt in a mixer to yield a mixture; compacting said mixture in a compactor to yield masses; crushing said masses in a crusher to yield particles; screening said particles in a screener to yield fine particles in three different sizes: oversized fine particles which undergo a second crushing process and are retuned to said screener for screening, undersized fine particles which are transferred to said mixer for further mixing, and desired size fine particles which are transferred to a polish screener glazing, drying and oiling.
