The least limiting water range (LLWR) has been used as an indicator of soil physical quality as it represents, in a single parameter, the soil physical properties directly linked to plant growth, with the exception of temperature. The usual procedure for obtaining the LLWR involves determination of the water retention curve (WRC) and the soil resistance to penetration curve (SRC) in soil samples with undisturbed structure in the laboratory. Determination of the WRC and SRC using field measurements (in situ […]

The least limiting water range (LLWR) has been widely used as an agronomic indicator of soil physical quality, however only a few studies have linked the LLWR to the plants growth and yield. The scarce results are insufficient to confirm or rebut the efficiency of LLWR, but indicate a discrepancy between LLWR and crop yields. The purpose of this study was to analyze the correlation of LLWR with variables of growth and grain yield of corn (Zea mays L.) in […]
