Study on measurement and statistical analysis of adherent soil chemical compositions of leguminous plants and their impact on nitrogen fixation
Abstract
The most important step of this study is to conduct the careful assessment of the interaction of leguminous plants with soil chemical compositions. The amount of chemical components as well as total nitrogen in adhered soil of ten species of leguminous plants and two species of non-leguminous plants with normal soil (controls) were measured at a site of Jhenidah district in Bangladesh. On average, the adjacent soil of leguminous plants was slightly alkaline; amount of nitrogen was low; phosphorus, zink and organic matter were medium; sulpher and boron were remained optimum. Interestingly, potassium was extremely high (1.11±0.37 Me/100g). The amount of nitrogen was soared to 35.89% in the adherent soil of Dalbergia sissooo compared with control soil. In this way, total nitrogen was accrued in the soil by the all ten leguminous plants. According to the regression analysis, for 12 ppm increase of phosphorus, there was only 0.01% rise in amount of nitrogen on average that affect greatly to the total soil nitrogen. However, soil pH has a less influence on this issue. The higher amount of nitrogen in soil sample indicating that leguminous plants have significant effect on amount of nitrogen in soil. Thus cultivation of legume crops might reduce the utilization of nitrogen based fertilizers.
