Evaluación de robustez y correlación entre análisis del método de determinación textural de suelos en Agrilab

Abstract

This document presents a study aimed at validating the Bouyoucos method for soil texture determination, highlighting its importance in the physical and chemical characterization of soil material. Through a multifactorial Youden experimental design and statistical analysis using ANOVA and PCA, the robustness and correlations between the sand, silt, and clay fractions were evaluated alongside physicochemical parameters such as pH, electrical conductivity, oxidizable organic carbon, and saturation pastes. The results showed that the method is reliable and stable under experimental variations, with significant associations between texture and soil fertility, particularly in clayey and fertilized soils. Overall, the study establishes the Bouyoucos technique as a valid tool for routine analysis and comprehensive interpretation of soil quality, strengthening analytical and quality control processes in specialized laboratories.
