The rhizosphere is the soil zone adjacent to plant roots which is physically, chemically, and biologically different from bulk or non-rhizosphere soil. Adaptative mechanisms of plants influence physical (temperature, water availability, and structure), chemical [pH, redox potential, nutrient concentration, root exudates, aluminum (Al) detoxification and allelopathy], and biological properties (microbial association) in the rhizosphere. These changes affect nutrient solubility, transport, and uptake and ultimately plant growth. Major rhizosphere changes are synthesized and their influence on nutrient availability is discussed. In the last decade, significant progress has been made in understanding the rhizosphere environment and nutrient availability. However, the subject matter is very complex and more research is needed to understand the interaction between the plant, the rhizosphere environment, and nutrient availability. |

The Panicum maximum cv. Mombaça is the most productive tropical grass. For this reason, it is used on intensive production systems submitted to high stocking rate and inputs uses, like nitrogen, irrigation, etc. The nitrogen use implies increases on biomass production due to its effects on morphogenetic plants characteristics. The objective of this work was evaluating morphogenetic and structural responses of mombaça grass receiving 100, 200 or 300 kg ha-1 of nitrogen in form of urea. It was used the randomized block design, with three treatments and four replicates (six paddocks of 0.25 ha each treatment), totaling 4.5 ha. |
