The impacts of trees on soil fertility depend on nutrient recycling characteristics such as litter chemistry and decomposition rates. Tree litter can be used as mulch with different outcomes a fast mulch decomposition rate may accelerate the growth of associated crops on poor soils, while in other cases a more persistent litter may provide a steady source of nutrients and a better soil cover year round. In the experiments in Costa Rica described in the previous section, high rates of litterfall and slower decomposition resulted in high litter accumulation and high... [Pg.113]

In 1781 he went to Edinburgh to study under the famous chemist and physician Dr. Joseph Black, and in the following year he entered Christ s College, Cambridge, where he studied chemistry, botany, mathematics, and Newton s Principia. His room at college was a scene of confusion books, papers, and chemical apparatus littered the floor, and his indolent and unsystematic habits were indeed a serious handicap throughout his scientific career (15). [Pg.436]

Vacuum technology takes necessary information from chemistry, physics and engineering. Possibly because of this, it is littered with a multiplicity of units, and both newcomers and experienced workers have often lacked the confidence to quantify their systems. It is fine to present... [Pg.243]

As said above, plant root chemistry may also influence deeply alpine soil microorganism s biomass. It turns out that the particular chemical composition of exudates is a strong selective force in favour of bacteria that can catabolize particular compounds. Plants support heterotrophic microorganisms by way of rhizodeposition of root exudates and litter from dead tissue that include phenolic acids, flavonoids, terpenoids, carbohydrates, hydroxamic acids, aminoacids, denatured protein from dying root cells, CO2, and ethylene (Wardle, 1992). In certain plants, as much as 20-30% of fixed carbon may be lost as rhizodeposition (Lynch and Whipps, 1990). Most of these compounds enter the soil nutrient cycle by way of the soil microbiota, giving rise to competition between the myriad species living there, from microarthropods and nematodes to mycorrhiza and bacteria, for these resources (e.g. Hoover and Crossley, 1995). There is evidence that root phenolic exudates are metabolized preferentially by some soil microbes, while the same compounds are toxic to others. Phenolic acids usually occur in small concentration in soil chiefly because of soil metabolism while adsorption in clay and other soil particles plays a minor role (Bliun et al., 1999). However, their phytotoxicity is compounded by synergism between particular mixtures (Blum, 1996). [Pg.921]
