LI, SL; ZHANG, YB; RUI, YK  e  CHEN, XF. Nutrient content in maize kernels grown on different types of soil. Phyton (B. Aires) [online]. 2012, vol.81, n.1, pp.41-43. ISSN 1851-5657.

Minerals are essential for human nutrition and plant growth and development. Nutrient concentrations in plants are related to many factors, including soil types. The impact of soil types on nutrient accumulation in corn, grown in black and sandy soils, was studied in the same area and management conditions. The results showed that the descending order of nutrient content was Ca > Fe > Zn > Mn > Cu > Se > Mo in both soil types. The contents of Ca, Mn, Fe, Se and Mo in kernels of corn grown in sandy soil were higher than those in corn grown in black soil. On the other hand, the contents of Cu and Zn in kernels of corn grown in sandy soil were lower than those in corn grown in black soil, although dif­ferences were not significant (p>0.05).
