Managing subsoil constraints - crop and varietal tolerance, rotations, fallow management, crop responses schwenke2_2.. Results from a species and varieties trial on an unconstrained soil in northwest NSW in 2004 (Table 2) also showed species differences in soil water use, but no differences between the varieties chosen for the study even though there were some differences in observed rooting depth and grain yields... Table 4: Species and variety responses at a constrained site in northwest NSW. Variety differences within a species are shown by the letter after the result; those with the same letter following were not significantly different...
