Microbial inoculants, nke a makwaara dị ka inoculants ala ma ọ bụ bioinoculants, bụ mmezi ọrụ ugbo na-eji rhizosphericic ma ọ bụ endophytic microbes bara uru iji kwalite ahụike osisi. Ọtụtụ n'ime ụmụ nje ndị ahụ metụtara na-emekọrịta mmekọrịta symbiotic na ihe ọkụkụ a na-achọsi ike ebe akụkụ abụọ ahụ na-erite uru (mutualism). Ọ bụ ezie na a na-etinye inoculants microbial iji meziwanye nri ihe ọkụkụ, a pụkwara iji ha kwalite uto osisi site na-akpali mmepụta hormone osisi.[1][2] Ọ bụ ezie na inoculants nje bacteria na fungal na-adịkarị, a na-amụbawanye ọmụmụ ihe na archaea iji kwalite uto osisi.
Nnyocha banyere uru nke inoculants na ọrụ ugbo gbatịrị karịa ike ha dị ka ihe na-emepụta biofertilizers. Inoculants microbial nwere ike ibute nguzogide sistemu enwetara (SAR) nke ụdị ihe ọkụkụ n'ọtụtụ ọrịa a na-ahụkarị n'ihe ọkụkụ (na-enye mgbochi megide nje nje). Ka ọ dị ugbu a egosipụtara SAR maka powdery mildew (Blumeria graminis f. sp. hordei, Heitefuss, 2001), were-all (Gaeumannomyces graminis var. tritici, Khaosaad et al., 2007), ntụpọ akwukwo (Pseudomonas syringae, Ramos Solano et al. al., 2008) na mgbọrọgwụ ire ere (Fusarium culmorum, Waller et al. 2005)

Rhizobacteria ndị a na-ejikarị eme ihe dị ka ihe na-eme ka nitrogen na-agbanye ọgwụ na-agụnye nitrogen-fixers, phosphate-solubilisers na nje bacteria ndị ọzọ na-arụ ọrụ nke na-emeziwanye nnweta nke nitrogen na phosphorus na osisi ahụ. A na-akpọkarị nje bacteria dị otú ahụ dị ka osisi na-akwalite uto rhizobacteria (PGPR).
Ihe rhizobacteria a na-ejikarị eme ihe bụ Rhizobium na mkpụrụ ndụ ihe jikọrọ ya. Rhizobium bụ nje na-edozi nitrogen nke na-etolite mkpakọrịta symbiotic n'ime nodules na mgbọrọgwụ nke mkpo. Nke a na-abawanye nri nitrogen ndị ọbịa ma dị mkpa maka ịkụ soybean, chickpeas na ọtụtụ ihe ọkụkụ ndị ọzọ. Maka ihe ọkụkụ na-abụghị nke ahịhịa, Azospirillum egosila na ọ bara uru n'ọnọdụ ụfọdụ maka nhazi nitrogen na nri osisi.
Maka ihe ubi ọka, diazotrophic rhizobacteria amụbawo ihe ọkụkụ, [4] mkpụrụ ọka (Caballero-Mellado et al., 1992), nitrogen na phosphorus, [4] na nitrogen (Caballero-Mellado et al., 1992), phosphorus ( Caballero-Mellado et al., 1992; Belimov et al., 1995) na potassium ọdịnaya (Caballero-Mellado et al., 1992). Rhizobacteria na-ebi na mgbọrọgwụ mgbọrọgwụ, na-ejikọta ya na mkpo.
Iji meziwanye nri nri phosphorus, ojiji nke nje bacteria phosphate-solubilising (PSB) dị ka Agrobacterium radiobacter enwetawokwa nlebara anya (Belimov et al., 1995a; 1995b; Singh & Kapoor, 1999). Dị ka aha ahụ na-egosi, PSB bụ nje bacteria na-enwere onwe ya nke na-akụda phosphates ala inorganic ka ọ bụrụ ụdị dị mfe nke na-eme ka osisi buru ibu.
A na-akpọ mmekọrịta mmekọrịta dị n'etiti fungi na mgbọrọgwụ osisi dị ka njikọ Mycorrhiza. Mmekọrịta symbiotic a dị n'ihe fọrọ nke nta ka ọ bụrụ osisi niile dị n'ala ma na-enye ma osisi ma fungus uru maka ịdị ndụ. Osisi ahụ nwere ike inye ihe karịrị 5-30% nke mmepụta ike ya na fungus iji gbanwere maka ịbawanye ebe mgbọrọgwụ na-amịkọrọ na hyphae nke na-enye osisi ahụ ohere ịnweta ihe oriri ọ gaghị enwe ike inweta. mycorrhizae abụọ a na-ahụkarị bụ arbuscular mycorrhizae ectomycorrhizae. A na-ahụkarị njikọ Ectomycorrhizae na ụdị osisi, ma nwee mmetụta dị ala maka usoro ọrụ ugbo.
Arbuscular mycorrhiza (AM) enwetala nlebara anya dị ka mmezigharị ọrụ ugbo maka ikike ya ịnweta ma nye osisi phosphorus. N'okpuru usoro na-ebelata uto nke ejiri ngwakọta nke AM Fungi AM Rhizobacteria mee ka ọ dị mma, a na-enweta tomato nke e nyere site na 100% ọmụmụ na 70% ọmụmụ.

Ọ bụ naanị ọgwụ nje fungus nwere ike ịba uru na osisi ndị na-elekọta ya. Inoculation jikọtara ya na mmezigharị ndị ọzọ nwere ike imeziwanye ọnọdụ.
