“Soil health goes beyond the quick fixes provided by chemical fertilizers. In fact, chemical fertilizers have extensively damaged our soils in Africa. We need to think of our soils in a more ...
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 .
A biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. [1]
Organic mulches, like wood chips, leaves, and other plant materials, are best at keeping the soil moist and moderating its temperature in hot and cold weather. They also add some nutrients and ...
In his two books First Principles of Soil Science (1857, 2nd ed. 1865) and Pedology or General and Special Soil Science (1862) Friedrich Albert Fallou developed his collected field observations of soil into a systematic approach. He explained why soil formation was worthy of study and appealed for recognition of soil science as a discipline. In ...
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.
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 ...
