Unlocking Field Capacity: A Reliable, Simple, and Budget-Friendly Indirect Approach.
Original language description
This study presents a cheap, fast and uncomplicated technique for indirectly determining the field capacity (FC) in soil, which is a crucial parameter for hydropedology, environmental modeling and irrigation applications. Relationships between FC and soil moisture constants, specifically maximum capillary water capacity (MCWC) and retention water capacity (RWC), were established using undisturbed soil core samples analyzed by pressure plate method and by "filter paper draining method”. This method involves determining the gravimetric soil water content of core samples. The samples were saturated and then allowed to drain naturally on the filter paper for a specified time interval (max. 24 hours). This method has long history of use in the Czech Republic as an approximate of FC, but it has never been correlated with a soil water content determined at a specific matric potential. The objective was to lower the time and expenses linked to conventional FC measurement techniques, and to enable the utilization of legacy databases comprising MCWC and RWC figures. The outcomes exposed the significant possibility of the "filter paper draining method" as an encouraging strategy for indirect FC determination. FC as soil water content at -33 kPa can be well approximated by the equation FC33 = 1.0802 RWC - 0.0688 (with RMSE = 0.045 cm3/cm3 and R = 0.953). For FC as soil water content at -5 or -10 kPa, either of the following equations can be used: FC5 = 1.0146 MCWC - 0.0163 (with RMSE = 0.027 cm3/cm3 and R = 0.961) or FC10 = 1.0152 MCWC - 0.0275 (with RMSE = 0.033 cm3/cm3 and R = 0.958), respectively.
