A fertile soil has the following properties: [4] The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and The absence of toxic substances which may inhibit plant growth e.g. Fe 2+ which leads to nutrient toxicity.
Its root system is generally shallow, so the plant is dependent on soil moisture. As a plant that uses C 4 carbon fixation, maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans. Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for ...
