Without surface runoff data, there are two doable explanations for your absence of subsurface movement afterwards in the developing year. Either:
Resulting from saturated circumstances near the soil surface area, the depth of crop root advancement may very well be severely restricted, even properly eradicated (in probably the most inadequately drained soils).
Other employs for land drainage are as dispersal drains for septic systems and as collector drains the place more formal drainage fittings could well be inappropriate.

Even though the agronomic terms “field potential” and “wilting issue” describe effortless agronomic reference details, soil moisture in the field is continually changing with time and may differ through the soil profile (the soil involving the ground surface and a certain click here depth).
