“…The LLWR has been used for identifying the limiting factors for plant growth under different tillage systems (Betz, Allmaras, Copeland, & Randall, 1998;Kahlon & Chawla, 2017;Tormena, da Silva, & Libardi, 1999) and soil management and land use (Calonego & Rosolem, 2011;Fidalski, Tormena, & Silva, 2010;Gonçalves et al, 2014;Reichert, da Silva, & Reinert, 2004), including forest soils (Sato, Lima, Ferreira, Rodrigues, & Silva, 2017;Zou, Sands, Buchan, & Hudson, 2000). The estimated da Silva et al (1994) LLWR values for topsoil conditions have been found to be related to crop yield (Beutler et al, 2008;Beutler, Centurion, & Silva, 2005;Lapen, Topp, Gregorich, & Curnoe, 2004).…”
