A moisture barrier coating includes the reaction product of (A) at least one polyol and (B) at least one polyisocyanate. The moisture barrier coating further includes at least one amorphous thermoplastic material that forms a homogeneous mixture with the polyol, and is nonreactive with the polyol and with the polyisocyanate. A controlled release fertilizer, a method for the production of a controlled release fertilizer, and a moisture barrier coating composition are also disclosed.

A semi-soluble humate granule includes a homogenous powder mixture. The homogenous mixture includes a raw humate, a fully soluble humic acid enriched powder, a seaweed powder, a zinc sulfate powder, a sulfur sulfate powder, a magnesium sulfate powder, a manganese sulfate powder, a ferrous sulfate powder, a copper sulfate powder, a borate powder, and a sodium molybdate powder. The homogenous mixture is granulated to form the semi-soluble humate granule having a pH of about 3.5 to about 8.5.

A treated biochar comprising a porous carbonaceous particle that has been treated and mixed with a media containing a mineral solubilizing microorganism, whereby the porous carbonaceous particle after mixing has retained the mineral solubilizing microorganism.
