Evaluating Method-Dependent Estimates of Volumetric Field Capacity in the Roldanillo–Unión–Toro Irrigation District, Colombia

Harold Tafur-Hermann · Estefania Osorio-Ocampo · Andrés Fernando Echeverri-Sánchez · Edwin Erazo-Mesa · y 1 más

Reliable estimates of volumetric water content at field capacity (θFC) are important inputs for irrigation scheduling because θFC contributes to the estimation of plant-available water, depletion thresholds, and refill targets. In irrigated systems, θFC is therefore an operational decision variable rather than a fixed...
