Colonization Ability

Arbuscular mycorrhizal fungi (AMF) are beneficial soil microorganisms establishing mutualistic symbioses with the roots of the most important food crops and playing key roles in the maintenance of long-term soil fertility and health. The great inter- and intra-specific AMF diversity can be fully exploited by selecting AMF inocula on the basis of their colonization ability and efficiency, which are affected by fungal and plant genotypes and diverse environmental variables. The multiple services provided by AMF are the result of the synergistic activities of the bacterial communities living in the mycorrhizosphere, encompassing nitrogen fixation, P solubilization, and the production of phytohormones, siderophores, and antibiotics. The tripartite association among host plants, mycorrhizal symbionts, and associated bacteria show beneficial emerging properties which could be efficiently exploited in sustainable agriculture. Further in-depth studies, both in microcosms and in the field, performed on different AMF species and isolates, should evaluate their colonization ability, efficiency, and resilience. Transcriptomic studies can reveal the expression levels of nutrient transporter genes in fungal absorbing hyphae in the presence of selected bacterial strains. Eventually, newly designed multifunctional microbial consortia can be utilized as biofertilizers and biostimulants in sustainable and innovative production systems.

Studies on the physical and chemical effects of extensive grazing on soils have been performed in Colombia, but the effects of dairy cattle rearing on the biological properties of soils are not well known. The objective of this study was to evaluate microorganisms in 48 soils from livestock farms in the highland and lowland tropics in the Northern and Magdalena Medio subregions of the Department of Antioquia (Colombia). Principal component analysis demonstrated differences in the edaphic compositions of the soils, with increased percentages of root colonization by arbuscular mycorrhizal fungi and the density of microorganisms in farms that have soils with moderate phosphorus and nitrogen contents, low potassium content, and a moderately acidic pH. Agglomerative cluster analysis showed two groups for the highland tropic soils and six groups for the lowland tropic soils based on their population densities and interactions with the studied parameters. These results represent a first attempt to describe the density of microorganisms and the effect of soil physicochemical parameters on colonization by arbuscular mycorrhizal fungi in areas with determinant agroecological conditions, microbial functional diversity, and the presence of mycorrhizal fungi in livestock farm soils in Colombia.

It is widely accepted that the symbiotic arbuscular mycorrhizal fungi (AMF) play a key role in sustainable production systems in rice cultivation and they readily form a symbiotic relationship with these fungi. Four species consortium of AMF, Funneliformis mosseae, Rhizophagus intraradices, Clariodeoglomus etunicatum and Glomus aggregatum, produced through in vitro production system and formulated with organic biostimulants viz. humic acids and sea weed extract were tested in this experiment, both for direct seeded and transplanted paddy, under anaerobic cultivation system. AMF inoculated fields produced significantly higher yield than non-inoculated field. AMF inoculants formulated with a blend of humic acids and seaweed extract produced significantly higher grain yield than the inoculants formulated with humic acids alone, in both the cultivation systems. Effect of AMF inoculation was highly pronounced in transplanted paddy than direct seeded paddy, resulted in highest grain yield, highest grain weight, better grain filling rate and highest tiller production. It can be concluded that AMF inoculants can be potentially used for rice cultivation under anaerobic water management system, both for direct seeded and transplanted paddy and the nature of biostimulants used in the formulation also play a key role in the efficacy of AMF inoculants. Our findings contribute to the growing global consensus that mycorrhizal inoculants could play a role in sustainable rice production systems of the future, when used appropriately.

Corn is one of stupple food to support economic growth in North Sumatera. The purpose of this research was to obtain data on the ability of compost derived from coffee husks and arbuscular mycorrhizal fungi in the growth and production of sweet corn plants (Zea mays sccharata Sturt). The method used in this study is a randomized block design (RDB) in factorial, with 2 (two) treatment factors, namely: 1) Factor coffee skin and  2) arbuscular mycorrhizal fungi (M), each treatment was repeated two (2) times so that there are 40 experimental plots. The parameters observed are plant height, number of leaves, cob length, sample crop production per plot, crop production per plot, top wet weight, bottom wet weight, percentage of pest attack, colonization of arbuscular mycorrhizal fungi, effectiveness of treatment application to all parameters. The results obtained from this study were: 1) The giving of coffee skin compost did not significantly affect the parameters of plant height, number of leaves, cob length, sample plant production per plot, crop production per plot, top wet weight and bottom wet weight; 2) The allocation of arbuscular mycorrhizal fungi has no significant effect on the parameters of observing plant height, number of leaves, cob length, sample plant production per plot, crop production per plot, top wet weight and bottom wet weight; 3) The combination of coffee husks compost and arbuscular mycorrhizal fungi did not significantly affect the parameters of plant height, number of leaves, length of cob, sample crop production per plot, crop production per plot, top wet weight and bottom wet weight.
