Parameter | Description | Units | Valid Values | Default Values |
---|---|---|---|---|
EPNFA(1) | Intercept value for determining the effect of annual precipitation on atmospheric N fixation (wet and dry deposition). This is the minimum annual amount. | g N m-2 year-1 | 0.0 to 9999.0 | |
EPNFA(2) | Positive slope for determining the effect of annual precipitation on atmospheric N fixation (wet and dry deposition). Atmospheric N inputs are a linear function of annual precipitation The slope is the rate of N fixation per cm of precipitation. | g N m-2 year-1 cm-1 precip. | 0.0 to 1.0 | |
EPNFS(1) | Intercept value for determining the effect of annual precipitation on non-symbiotic soil N fixation. | g N m-2 year-1 | -1.0 to 1.0 | -0.9 |
EPNFS(2) | Slope value for determining the effect of annual precipitation on non-symbiotic soil N fixation. | g N m-2 year-1 cm-1 precip. | 0.0 to 1.0 | 0.015 |
SATMOS(1) | Intercept for atmospheric S inputs as a linear function of annual precipitation. | g S m-2 year-1 | 0.0 to 9999.0 | |
SATMOS(2) | Slope for atmospheric S inputs as a linear function of annual precipitation. Atmospheric S inputs are a linear function of annual precipitation | g S m-2 year-1 cm-1 precip. | 0.0 to 1.0 | |
SIRRI | S concentration in irrigation water. | mg l-1 | 0.0 to 1000.0 |
