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 ...
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
Experts say soil acidity causes land degradation by decreasing the availability of plant and essential nutrients, making soil more vulnerable to structure decline and erosion.
Soil is used in agriculture, where it serves as the anchor and primary nutrient base for plants. The types of soil and available moisture determine the species of plants that can be cultivated. Agricultural soil science was the primeval domain of soil knowledge, long time before the advent of pedology in the 19th century.
C Habilitation with Venia Legendi for Plant Nutrition and Soil Science, Kassel University, 2004. There followed an appointment as Professor of Fertilization and Soil Matter Dynamics (Former Fertilization with Soil Chemistry)in the Institute of Plant Nutrition (today Institute of Horticultural Science) at Hohenheim University.
Microorganism function is in long duration, causing improvement of the soil fertility. It maintains the natural habitat of the soil. It increases crop yield by 20-30%, replaces chemical nitrogen and phosphorus by 30%, and stimulates plant growth. It can also provide protection against drought and some soil-borne diseases.
They conduct research in irrigation and drainage, tillage, soil classification, plant nutrition, soil fertility, and other areas. Although maximizing plant (and thus animal) production is a valid goal, sometimes it may come at high cost which can be readily evident (e.g. massive crop disease stemming from monoculture ) or long-term (e.g. impact ...
