Optimal soil depth is between 50 and 100 cm, [11] with a light soil texture. [11] Soil fertility should be low [11] and soil pH is best suited between 5 and 6.5 [11] and should not be lower than 4.3 [11] or higher than 7. [11] Bambara groundnut is tolerant to salinity, but high sodium chloride concentration in the soil will result in yield losses.
Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H +) into the soil through proton pumps. These hydrogen ions displace cations attached to negatively charged soil particles so that the cations are available for uptake by the root. In the leaves, stomata open to take in carbon dioxide and expel ...
The snap pea is a cool season legume. It may be planted in spring as early as the soil can be worked. Seeds should be planted 25–40 mm (1– 1 + 1 ⁄ 2 in) apart and 15–25 mm (1 ⁄ 2 –1 in) deep in a 75 mm (3 in) band. [6]
Investors in the fertilizer industry received a pleasant surprise last week when Cowen & Co. upgraded its rating on three fertilizer stocks -- PotashCorp , Agrium , and Rentech Nitrogen -- to ...
Black-eyed peas, a common name for a cowpea cultivar, are named due to the presence of a distinctive black spot on their hilum. Vigna unguiculata is a member of the Vigna (peas and beans) genus. Unguiculata is Latin for "with a small claw", which reflects the small stalks on the flower petals. [7]
A pea is a most commonly green, occasionally golden yellow, [6] or infrequently purple [7] pod-shaped vegetable, widely grown as a cool-season vegetable crop. The seeds may be planted as soon as the soil temperature reaches 10 °C (50 °F), with the plants growing best at temperatures of 13 to 18 °C (55 to 64 °F).
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 ...
