Drought Resistant Soil (Summary)
Drought Resistant Soil (Summary)
To
minimize the impact of drought, soil needs to capture the rainwater
that falls on it, store as much of that water as possible for
future plant use, and allow for plant roots to penetrate and
proliferate. These conditions can be achieved through management
of organic matter, which can increase water storage by 16,000
gallons per acre foot for each 1% organic matter. Organic matter
also increases the soil's ability to take in water during rainfall
events, assuring that more water will be stored. Ground cover
also increases the water infiltration rate while lowering soil
water evaporation. When all these factors are taken together
the severity of drought and the need for irrigation are greatly
reduced.
