Water retention and penetration resistance equations for the least limiting water range [PDF]
Scientia Agricola, 2019 : The least limiting water range is a soil physical quality indicator, which is useful to predict the optimum water range for plant growth in a given soil and to study the effects of soil use and management over this optimum water range by integrating ...

Water availability to soybean crop as a function of the least limiting water range and evapotranspiration [PDF]
Pesquisa Agropecuária Tropical, 2017 Irrigation management aimed at optimal production has been based only on the water factor. However, in addition to the water potential of the soil, factors such as soil penetration resistance and soil O2 diffusion rate also affect plant growth and ...

Least limiting water range in soil under crop rotations and chiseling
Revista Brasileira de Ciência do Solo, 2011 Soil water availability to plants is affected by soil compaction and other variables. The Least Limiting Water Range (LLWR) comprises soil physical variables affecting root growth and soil water availability, and can be managed by either mechanical or ...

Using root water uptake estimated by a hydrological model to evaluate the least limiting water range [PDF]
Revista Brasileira de Ciência do Solo, 2020 The least limiting water range (LLWR) has been extensively determined, but evaluating if LLWR can indeed indicate soil physical stress on plant growth is still a controversial issue.

Quantification of the least limiting water range in an oxisol using two methodological strategies [PDF]
Revista Brasileira de Ciência do Solo, 2014 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
