There is provided herein a granule of potash and polyhalite comprising: at least 10% Potash; at least 10% Polyhalite; optionally a binder; and wherein said granule comprises a bulk density of at least 1 T/m.sup.3 and single strength of between 1-5 kg/granule.

A method is provided for producing a biochar solution. The method comprises the steps of collecting biochar particles, dispersing the biochar particles in a liquid solution and adding a stabilizing agent to keep the biochar in flowable suspension. The stabilizing agent may be added to the liquid solution or to the biochar prior to placing the biochar in solution.

Compositions and methods are provided for seed treatment to improve seed appearance, flowability, and plantability while minimizing fugitive dust. Inclusion of a water miscible non-solvent in the seed treatment composition is found to minimize fugitive dust. Further advantages of the seed treatment compositions include that they are non-toxic and microplastic free, reduce drying time for liquid treated seed, and have an increased shelf life relative to seed lubricant compositions based on plant oils that can become rancid over time.

A wax-based coating for fertilizer granules capable of supplying micronutrients to soil while increasing the surface hydrophobicity and abrasion resistance of the fertilizer granules is disclosed. The wax-based coating provides the flexibility of formulating slow and fast releasing micronutrients, and ensures micronutrients are evenly coated across every fertilizer granule. Single or multi-nutrient combinations of coatings are possible, providing formulation flexibility.

A particle is provided for delivery of humics, and biochar that is water-dispersible into constituent granules. The resulting particles are amenable to broadcast application, for example via rotary or drop spreader. As a result, a dust-free particle is formed that simultaneously addresses the prior art problems of the friable nature of humics and the sooty dusting property of biochar to facilitate ease of handling, broadcast field spreading, and gain the synergistic effects of dosing soil with both humics and biochar. The particle provides improved storage capabilities for materials improving the quality of the delivered material and decreasing negative storage consequences such as odor emanation or degradation. The resulting particles upon dispersion have a pH of between 3.3 and 8.1.
