Simple and Cost-Effective Method for Reliable Indirect Determination of Field Capacity
Original language description
This study introduces a simple and cost-effective method for the indirect determination of field capacity (FC) in soil, a critical parameter for soil hydrology and environmental modeling. The 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 via the pressure plate method and the "filter paper draining method". The aim was to reduce the time and costs associated with traditional FC measurement methods, as well as allowing for the use of legacy databases containing MCWC and RWC values. The results revealed the substantial potential of the "filter paper draining method" as a promising approach for indirect FC determination. FC determined as soil water content at -33 kPa can be effectively approximated by the equation FC33 = 1.0802 RWC - 0.0688 (with RMSE = 0.045 cm3/cm3 and R = 0.953). FC determined as soil water content at -5 or -10 kPa can be effectively approximated by both equations FC5 = 1.0146 MCWC - 0.0163 (with RMSE = 0.027 cm3/cm3 and R = 0.961) and FC10 = 1.0152 MCWC - 0.0275 (with RMSE = 0.033 cm3/cm3 and R = 0.958), respectively. Historical pedotransfer functions by BreznATIN SMALL LETTER Y WITH ACUTE and Vasa relating FC to fine particle size fraction were also evaluated for practical application, and according to the results, they cannot be recommended for use.
