SOIL HEALTH
Drought-prone
orchards
Many growers have
the challenge of keeping
moisture levels adequate year
after year. Investing in an innovative
soil microbial food can wake up soil microbes and
improve water holding capacity to support trees during
times of drought.
In warm, dry climates, soil microbes are able to
create larger soil aggregates with microbial glues and
nets. They increase soil moisture infiltration and
the capacity for moisture storage. They improve an
orchard's resistance to drought stress and increase
water productivity.
With increased penetration and infiltration, soil
microbes help healthy soil transport water from the
soil surface to down around the root zone and store the
water in the soil. Farms with healthy soil lose less water
in runoff, and soil moisture reserves from winter can
contribute to the growing season's evapotranspiration and
lessen irrigation needs. Thus, feeding soil microbes makes
the most of water year-round.
This is important because water intake affects nutrient
intake. Water is the main channel roots use to intake
nutrients and nutrient mobility. Water productivity makes
nutrients more mobile, meaning nutrients can move
through well-structured soil to where they're needed.
Drought conditions not only mean less water, but also less
nitrogen and phosphorus intake, yielding a worse ROI on
already expensive fertilizer.
Soil microbes also release a substance into the soil
near the tree's roots that can help manage abiotic stress.
Osmoprotectants manage challenges by aiding in water
balance under drought conditions. Antioxidants mitigate
oxidative stress and internal plant cell damage during
