The leaves of the corn crop are long lanceolate, alternate and parallelinervous, large, form a sheath rolled to the stalk, the blade wider and elongated and the beam has hairs. The ends of the leaves are very sharp and cutting. As for the roots, these are fasciculate and their mission is to provide a perfect anchorage to the plant..
▶ In some cases, some root knots protrude at soil level and usually occur in those secondary or adventitious roots, which end up expanding the area of water absorption and anchoring of the crop.

Regarding the soil, it is pointed out that corn is a crop that needs structured, fertile and deep soils that allow the development of the roots; they must be able to store water for an optimal use of nutrients, but avoiding waterlogging.
He also points out that Conservation Agriculture, and more specifically no-tillage, has shown that in a soil with the characteristics described above, corn can have a perfect vegetative development and reach its maximum production.
The development of the root system will depend on all factors such as: moisture and soil preparation conditions that were presented to the seed, in well prepared porous soils with good moisture from the beginning of germination, the root can reach up to one point eighty meters (1.80 meters) deep.
In sandy loam soil with abundant moisture availability, it is estimated that during the first twenty-five (25) days the corn plant has a rapid development that is close to forty or fifty centimeters (40-50 cms), which will increase in size if the conditions of fertility, porosity and moisture are favorable, can reach a depth of one point sixty or one point eighty meters square (1.60-1.80 m2).
