plant propagation material treated with a carbonacean material, method of 4 treatment of plant propagating material, composition, method of inducing microbial interaction with plant propagating material and use of a composition to treat plant propagation material
Plant propagation material treated with a carbonaceous material is provided. Such treated plant propagation material is useful in a method of inducing microbial interaction with the plant propagation material that confers a benefit on the plant propagation material. The method includes placing the treated plant propagation material in a growth medium containing endogenous soil microorganisms.
