Water inputs to the root zone include effective rainfall (the fraction of total rain that infiltrates the soil after losses to leaf interception, surface runoff and depression storage, and evaporation) and irrigation (vineyard only).
c] values for daily water use by plants, the primary parameters affecting groundwater use are effective rainfall, available water capacity and maximum allowable depletion.
Increasing effective rainfall values implies that a greater proportion of daily rainfall infiltrates and thereby more rapidly replenishes soil moisture while increasing possible deep percolation.
5: Effect of effective rainfall fraction used in modeling on net annual groundwater recharge for vineyard and equivalent oak woodland.
We only abstract for public water supply around 3% of effective rainfall in our region compared with, for example, over 50% in the South East of England.
We use just 3% of the effective rainfall in our region, compared with around 20% in the south east of England.
By comparison, there were much higher rates of net N mineralisation (155 kg/ha [multiplied by] year) and leaching of mineral N (149 kg N/ha in 2 years) from fertilised soil, leaching of mineral N being highly correlated with soil mineral N content and effective rainfall.
3] (or total mineral N) and effective rainfall (rainfall minus evaporation) or initial [NO.
The relationship between mineral N leaching and effective rainfall (r = 0.
The controller then deducts effective rainfall amounts from the ET rate to determine how much water is needed to maintain the optimum level of moisture in the soil.
The ESP-SMT then deducts effective rainfall amounts to determine how much water is needed to maintain the optimum level of moisture in the soil.
