Descripción
The least limiting water range (LLWR) integrates crop growth-limiting values based on easily measurable parameters such as soil water content and bulk density (BD) and has been validated as a valuable soil physical quality indicator for a wide range of soils, crops and management systems. When the LLWR is zero, the soil achieves the critical bulk density value (BDc). Another methodology to assess the level of soil compaction and its effect on crop growth is the shear strength (SS) of the soil. The aims of this work were: i) to obtain critical bulk density values for a Mollisol and a Vertisol using the LLWR and assess their effects on early wheat growth, and ii) to evaluate the variation in early wheat growth as affected by the increases in BD and SS. To this end, an experiment in pots containing disturbed soil from an Aquic Argiudoll and a Typic Hapludert was carried out. Soil cores obtained from agricultural paddocks were mechanically compacted to 1.1, 1.2, 1.3, 1.4 and 1.5 Mg m-3. Wheat was grown on half of the pots for two months, and, after that, both shoot and root biomass were measured. LLWR and SS were evaluated in the remaining non-sowed cylinders as a function of the increase in BD. Critical bulk density was 1.44 Mg m-3 and 1.37 Mg m-3 for the Mollisol and the Vertisol, respectively. Although both soils fit in the same textural class (silty clay loam), the Vertisol has clay dominated by smectite mineralogy. In the Mollisol, wheat growth was limited when BD>1.4 Mg m-3 due to the lack of aeration rather than to the high penetration resistance. In the Vertisol, early wheat growth was not affected by BD due to volumetric changes. Soil shear strength was significantly correlated with BD and was sensitive to soil water changes. Bulk density values higher than 1.35 Mg m-3 had high SS values. This measurement also allowed us to obtain a critical value for crop growth, but only for the Mollisol (50 kPa). When deciding which soil properties should be measured to quantify soil structure or to identify soil quality indicators, SS appears as a fast and operative simple methodology with predictive value of crop response. The concept of LLWR and BDc were useful to determine a threshold for early wheat growth in the Mollisol, but was useless for the Vertisol. These findings provide an interesting plataform for the management of soils with similar textural classes and different clay mineralogy, particularly when they are present in the same paddock across the landscape.
