  • Essay / Plant Growth: Nutrient Use Efficiency - 966

    Nutrient Use Efficiency (NUE)Plants acquire mineral nutrients primarily from soil in the form of inorganic ions. These minerals are cycled throughout all organisms and first enter the biosphere through the root systems of plants, in doing so the plants act as miners of the earth's crust (Epstein, 1999). The large surface area of ​​the root system of plants and their ability to absorb nutrients, even those present in low concentrations in the soil solution, make the process of mineral absorption very efficient. Increased agricultural yield depends on the availability of nutrients applied through fertilization and the yield of most crops increases linearly with the amount of nutrients absorbed (Loomis and Conner, 1992). Almost all elements mentioned in the periodic table are present in the soil solution. Only certain elements have been considered essential from the point of view of plant growth. An element is said to be essential if a plant cannot complete its life cycle in the absence of a particular element (Arnon and Stout, 1939) or an element is considered essential if it has a clear physiological role (Epstein, 1999). Essential elements are constituents of major plant biomolecules, including proteins, chlorophyll and nucleic acid, and are necessary for processes such as energy transfer, maintaining internal cell pressure and proper functioning of cells. enzymes. The world's population is growing rapidly and is expected to reach 8.5 billion by 2025. Such an increase in population will increase pressure on natural resources such as water and air. In order to meet the growing food demand of the population, the use of primary mineral fertilizers (nitrogen, phosphorus and potassium) has also increased steadily in the agricultural sector around the world. ...... middle of article ......N., MH Barrett, KM Hiscock, PP Dennis, NA Feast and DN Lerner. 1996.
