Biobased Industrial Products
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309175402
Category : Science
Languages : en
Pages : 162
Book Description
Petroleum-based industrial products have gradually replaced products derived from biological materials. However, biologically based products are making a comebackâ€"because of a threefold increase in farm productivity and new technologies. Biobased Industrial Products envisions a biobased industrial future, where starch will be used to make biopolymers and vegetable oils will become a routine component in lubricants and detergents. Biobased Industrial Products overviews the U.S. land resources available for agricultural production, summarizes plant materials currently produced, and describes prospects for increasing varieties and yields. The committee discusses the concept of the biorefinery and outlines proven and potential thermal, mechanical, and chemical technologies for conversion of natural resources to industrial applications. The committee also illustrates the developmental dynamics of biobased products through existing examples, as well as products still on the drawing board, and it identifies priorities for research and development.
Some Trends in Land Classes I and II

Book Description
Excerpt from Some Trends in Land Classes I and II: An Analysis of Two Areas in Southern New York In 1927, studies were made in several areas throughout southern and central New York, the results of which are reported in Bulletin 490, Abandoned Farm Areas in New York. In general these studies show that the abandoned areas are naturally low in productivity. This condition is due primarily to poor soil and a short growing season resulting from high elevations. The size and condition of buildings, the amount of livestock kept, the kind of crops grown, and the yields per acre are all evidences of this low productivity. The almost exclusive use of the cleared land for small grains, hav and pasture, and the fact that the yields were from one-third to one-half less than State average in 1926 during a comparatively good farming period and under the management of experienced farmers is substantial evidence that cannot be overlooked (table Furthermore, all facts in the history of these areas would bear out the conclusion that the present low productivity is not a new thing and that it is primarily a result of inherent inability to pro duce rather than soil depletion or poor management.

Sustainable Agriculture Research and Education in the Field
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309045789
Category : Technology & Engineering
Languages : en
Pages : 456
Book Description
Interest is growing in sustainable agriculture, which involves the use of productive and profitable farming practices that take advantage of natural biological processes to conserve resources, reduce inputs, protect the environment, and enhance public health. Continuing research is helping to demonstrate the ways that many factorsâ€"economics, biology, policy, and traditionâ€"interact in sustainable agriculture systems. This book contains the proceedings of a workshop on the findings of a broad range of research projects funded by the U.S. Department of Agriculture. The areas of study, such as integrated pest management, alternative cropping and tillage systems, and comparisons with more conventional approaches, are essential to developing and adopting profitable and sustainable farming systems.
