    INTRODUCTION N oise is acoustically made up of numerous sound waves with anarchically distributed amplitude and phase ratios, causing an unpleasant sensation1. Noise can be continuous - when there is no variation in terms of sound pressure nor sound spectrum; floating - when it presents variations in terms of acoustic energy in function of time; or impact noise - with acoustic energy peaks lasting for less than a second, at intervals greater than one second2. Impact noises are usually produced by

    Phosphorus metabolism : The endomycorrhizal symbiosis is beneficial for both fungi and plant. Fungi provide phosphorus to the plant while plant as a result give carbon to the fungi. But the phosphorus metabolism is the most important part of this association. Phosphorus is first absorbed by fungi from the soil and is stored in its cytoplasm while later fungi transport it to its vacuoles. Then these vacuolar components containing phosphoros are transported from outer mycelium of fungi to the plant

  • Phosphorus In Plant Essay

    1487 Words  | 6 Pages

    1. Introduction Phosphorus (P) is vital for the growth of plants and is the second major macro-element after nitrogen, which limits plant growth (Gyaneshwar et al., 2002). Most of the soluble inorganic phosphate is applied annually to the soil as a chemical fertilizer, which is immobilized quickly and again becomes inaccessible to plants. Hence, the lower amount of soluble P in soil is one of the limiting factors for agronomic crop production. Fertilizers (microbial inoculant) offer a solution, as
