“…Accordingly, [16] also observed that the incorporation of lime did not favor the growth of the root system of maize compared to surface application using limestone with 100% PRNT. Since [21] found that the incorporation of lime in the rate of 6.8 t•ha −1 in a dystrophic Ultisol promoted root growth of maize to 0.45 m depth in the soil, compared to liming. Even without incorporating limestone with a particle size between 0.30 mm and 0.20 mm caused greater root development in 20 a 40 cm soil layer in the second year.…”

“…Pursuant to, limes were effective to promote rooting of plants. Furthermore, [19] reported that the incorporation of lime dose of 6.8 t•ha The values of root length density (CRV) and (CRM) in the first year were higher than those found by [16]. These authors reported that the roots of maize in two cropping system, direct and conventional, were with root length density around 1.0 cm −3 cm to 1.5 cm•cm −3 while using different particle sizes limestone this value was about 0.02 cm•cm −3 to 2.30 cm•cm −3 depending on the soil depth.…”

“…Quanto à distribuição do acúmulo total de C pelas raízes, em termos percentuais por profundidades (Figura 3), houve maior concentração no plantio direto que no sistema convencional, na profundidade de 0,0-0,1 m, tanto para a soja quanto para o milho, ao contrário do observado em outros trabalhos (Vieira, 1981;Tavares Filho et al, 2001). Leite et al (2006) também relataram maior incidência de raízes de milho no sistema de plantio direto do que preparo convencional, nos primeiros centímetros de profundidade, em razão de o plantio direto apresentar boas propriedades químicas em superfície, principalmente em relação a pH e Ca 2+ , quando há aplicação superficial de calcário sem incorporação ao solo.…”
