Microbial compositions comprising at least two components are disclosed. The first component comprises HYTa which is a consortium of microbes derived from fertile soils and commercial sources. The second component comprises at least one of chitin, chitosan, glucosamine and amino acids. The various microbes in HYTa are capable of fixing nitrogen, digesting proteins and other biopolymers such as chitin and chitosan, providing protection against plant pathogens and supplementing the microbial flora of soil. Also disclosed are processes where the aforementioned microbial compositions are used to treat soil, seeds, seedlings and/or plant foliage alone or in combination with chitin, chitosan, glucosamine and/or amino acids.
