Estimating the yield effect of soil degradation

, : Estimating the yield effect of soil degradation. Journal of Soil and Water Conservation 47(6): 486-490

Cost-benefit analysis is often used to examine the returns to conservation measures. A commonly-used approximation in such exercises consist of using a constant estimate of the yield decline induced by soil degradation over the period of analysis. This approximation is shown to distort significantly the results of the analysis, both quantitatively and qualitatively.

An established cell line (TC-cell, clone 78) derived from human thyroid papillary cancer cells was investigated for production of peptide growth factors. The cells had specific binding sites for insulin-like growth factor-I (IGF-I) and responded t...

However, the low DNA content of such samples makes DNA amplification difficult, and there is the potential for erroneous results when one of two alleles at h...
