“…By the ease of driving the crop, this plant is used in rotation to substitution for wheat in the winter and corn in the second crop, because of its low cost, high versatility and high value added to the final product, its grains are brown or gold (Milisich, 2017;Bassegio, Santos, Nogueira, Cattaneo, & Rossetto, 2012). However, scientific information about flax crop is very scarce in the country, especially those related to soil and plant root interaction in crop productivity (Kohn et al, 2016;Carducci et al, 2017;Stanck et al, 2017Stanck et al, , 2017Xavier, Carducci, Viana-Moraes, Ferreira, & Turtt, 2018). These interactions between roots and soil are the key element for the second green revolution that has, by purpose, to maximize productivity (Lynch, 2007).…”
