Pedotransfer Functions For Estimation Of Soil Moisture Constants From Penetration Resistance Measurements And Some Soil Properties

Studies to prediction of soil moisture constants and other properties rather than direct measurements were never dwindle importance. Models derived from obtained easily. Therefore, in this study focused on the predictability some constants, whose determination was often difficult time-consuming, penetration resistance measurements. In improvement alternative models for estimation constants; addition resistance, textural fractions (sand, clay silt), bulk density, CaCO3 % organic matter contents included. The created according groups with different textures (sandy, loamy, clay) at 0.1, 0.33, 0.5 15 bar. bar content, highest differences R2 values (0.61, 0.60, 0.64 0.59) between actual predicted data loamy soils. For group, root means square error (RMSE) ranged 1.32 1.90 %, addition, mean (ME) determined be a range 1.53 2.05 %. content tensions using matter, properties, coefficient 71 77 it is concluded that models, developed or by could used safely texture
