The tensile strength was positively correlated SOC concentration only at the 1st drainage when the soils became consolidated,
but did not experience drying (Fig. 5), but not at the 2nd and 3rd
drainage when the soils experienced one and two drying and
rewetting cycle(s). Soil tensile strength is a significant parameter in
determining the energy required to break soil into smaller
aggregates by cultivation, to initiate/form cracks under hydraulic
stress and for plant roots and biota to penetrate and excavate soil
(Humberto and Lal, 2007).
