Nutrient fluxes between soil and plant

VESTA benefit to strawberry plant nutrient uptake and to the environment

Nutrient dynamics in strawberry fields

Fields of commercial strawberries were treated with VESTA, a liquid product composed of a broad spectrum of microbes and soluble carbon (VESTA®, SOBEC Corporation, Fowler CA).

As a good source of nutrients, strawberries are a valued crop for their antioxidant and anti-inflammatory properties. Strawberries also provide healthy doses of Dietary Fiber, Vitamin C, Manganese, Folate and Potassium. Microbial activities in the soil and root endosphere are expected to mobilize nutrients, and make them available for uptake by the plant.

In this study, we investigated the effect of VESTA on nutrient exchange. Several nutrients were increased in strawberry leaves. There was increased root growth, increased % water in roots over time, and % Nitrogen and % Carbon (per dry weight) in leaves.

Our results indicate that VESTA influences nutrient flux between the soil and the plant possibly through microbial activity. It is likely that fungal activity is involved. Further analyses are needed to determine the critical mechanisms and activities of VESTA organisms associated with plant nutrient exchange.

Examining the benefits of healthier soil microbiota

VESTA benefits strawberry production

Strawberry production gets a boost from beneficial microbes

Commercial strawberries grown in Guadalupe, CA were treated with VESTA, a fermented liquid product composed of a broad spectrum of microbes and soluble carbon (VESTA®, SOBEC Corporation, Fowler CA). VESTA is a commercially successful biological product, approved for organic agriculture, and certified pathogen free. The purpose of this study was to test the effect of VESTA on soil, rhizosphere, and root endosphere. Samples from untreated (control) and treated strawberry beds in neighboring fields were subjected to microbiome analyses.
