Soil structure affects aeration, water movement, conduction of heat, plant root growth and resistance to erosion. [26] Water, in turn, has a strong effect on soil structure, directly via the dissolution and precipitation of minerals, the mechanical destruction of aggregates [27] and indirectly by promoting plant, animal and microbial growth.
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Severe root injury interferes with the roots' ability to transport water and nutrients, reduces growth and results in reduced grain production. Severe root injury may result in lodging of corn plants, making harvest more difficult. Silk feeding by adults can result in pruning at the ear tip, commonly called silk clipping. In field corn, beetle ...
Goeppertia allouia (syn. Calathea allouia), known as lerén or lairén in Spanish, and also known in English as Guinea arrowroot, and sweet corn root, is a plant in the arrowroot family, native to northern South America and the Caribbean. The name "allouia" is derived from the Carib name for the plant. [2]
In specific plant/root symbiotic relationships, the plant root secretes flavonoids into the soil, which is sensed by microbes, which release nod factors to the plant root, which promotes the infection of the plant root. These unique microbes carry out nitrogen fixation in root nodules, which supplies nutrients to the plant.
The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.

Tillers formed; leaves often twisted spirally. Main shoot and six tillers.
