Estimation of precompression stress in an Ultisol cultivated with sugarcane [PDF]
Revista Brasileira de Engenharia Agrícola e Ambiental, 2019 ABSTRACT Compressive soil properties are typically used for the understanding of compaction process. As an alternative to laboratory tests, pedo-transfer functions have been used to estimate the mechanical behaviour of soil as a function of soil physical parameters.
