“…B-splines (Zheng & Chen, 2022) were used in this study to estimate the error curves at each of the 75 measurement sites. Next, these curves were subjected to functional kriging (Mateu & Giraldo, 2022) by removing one error curve at a time and performing functional kriging on the remaining 74 curves to predict the "missing" curve, which resulted in the "observed" curve (estimated using B-splines) and the predicted curve for the unmeasured site (using functional kriging).…”

Soil is a medium that stores and transfers air, water, nutrients and heat to microorganisms and plants. Its water storage capacity is studied by analysing water retention curves (WRCs), which establish the relationship between soil water content and the force with which water is retained. The objective of this work was to evaluate the capacity of functional geostatistics in predicting the spatial distribution of water retention curves in two types of soils. Experimental areas with two types of soil, Andisol and Oxisol, were selected, and a regular grid of 75 sites was established, from which water retention curves were obtained at two depths. The curves were subjected to geostatistical functional analysis (GF), and the applicability of this method was evaluated by obtaining the usable water table (LAA) and comparing the results with experimental data obtained using traditional methods. Based on cross-validation, it was verified that GF produced a better fit for the Andisol since the coefficient of determination between the LAA values for the measured data and predictions was high, with an R2 of 99%; however, the proposed methodology was also reliable for the Oxisol, since an R2 of 94% was obtained at the two depths studied.
