15 صفحه اولChemical fertility of forest soils: basic concepts
Fertility is a very old concept and many definitions are available in literature. The first edition of the Dictionnaire de l’Académie Française in 1694 defines fertility as: “quality of that which is fertile; good farming is that which contributes most to the fertility of the soil” (the capacity of a soil to produce a large harvest). A more accurate definition appeared in the 18th century in th...
متن کاملSeasonal greenhouse gas emissions (methane, carbon dioxide, nitrous oxide) from engineered landfills: daily, intermediate, and final California cover soils.
Compared with natural ecosystems and managed agricultural systems, engineered landfills represent a highly managed soil system for which there has been no systematic quantification of emissions from coexisting daily, intermediate, and final cover materials. We quantified the seasonal variability of CH, CO, and NO emissions from fresh refuse (no cover) and daily, intermediate, and final cover ma...
متن کاملBioeconomic Modeling of Greenhouse Whiteflies in California Strawberries
When a species invades an agricultural system, policymakers and producers need ways to compare the cost and benefits of control alternatives. In this paper, we examine the greenhouse whitefly invasion of California strawberries and a set of control alternatives, along with the effects of the information included in the analytical framework. The greenhouse whitefly invasion into California straw...
