An agricultural product, comprising:
- a grass seed;
- and
- a composite coating at least partially enclosing the grass seed, the composite coating comprising a plurality of coating layers, and the plurality of coating layers comprising:
- a first coating layer extending at least partially around the grass seed,
- a second coating layer extending at least partially around the first coating layer,
- a third coating layer extending at least partially around the second coating layer,
- a fourth coating layer extending at least partially around the third coating layer, and
- a fifth coating layer extending at least partially around the fourth coating layer,
- wherein at least two coating layers of the plurality of coating layers:
- each extend completely around the grass seed,
- are not contiguous with one another,
- are spaced apart from one another, and
- each comprise fertilizer, the fertilizer
- comprising urea and calcium nitrate,
- wherein at least two other coating layers of the plurality of coating layers are coating layers of a non-nutritive material and/or a nutritive material that:
- each extend completely around the grass seed,
- are not contiguous with one another,
