Field inoculation by arbuscular mycorrhizal fungi with contrasting life-history strategies differently affects tomato nutrient uptake and residue decomposition dynamics

Abstract Purpose Plant microbial biostimulants, such as arbuscular mycorrhizal fungi (AMF), enhance nutrient concentration in fruits, including tomato. However, field studies on tomato AMF inoculation are scarce. species belonging to Gigasporaceae and Glomeraceae families known vary life-history strategies may determine differential effects plant benefits residue decomposition. Despite this, the effect of different acquisition fruits has not been investigated yet. Methods We studied two varieties with four Gigasporaceae. Fungal colonization, yield, fruit concentration, litter decomposition, bacterial fungal abundances soil were assessed under organic agriculture. Results Overall promoted nutrients compared Glomeraceae. A variability AM colonization was detected within Scutellospora pellucida increased yield (+ 27%) var. Rio Grande respect Gigaspora gigantea . In Grande, Funneliformis mosseae did change decomposition non-inoculated controls, whereas it lower than Sclerocystis sinuosa species, which showed highest rates. total abundance fungal:bacterial (F:B) ratio members had F:B ratio. Conclusion These findings pointed at inclusion strategy selection criteria for development biofertilizers able nutritional value vegetables farming systems.
