Use of Detergents in the Analysis of Fibrous Feeds. II. A Rapid Method for the Determination of Fiber and Lignin
TLDR
The acid-detergent fiber method (ADF) as mentioned in this paper is a fiber method based on cetyl trimethylammonium bromide to dissolve proteins in acid solution.Abstract:
The capacity of cetyl trimethylammonium bromide to dissolve proteins in acid solution has been utilized in development of a method, called acid-detergent fiber method (ADF), which is not only a fiber determination in itself bnt also the major preparatory step in the determination of lignin. The entire procedure for determining fiber and lignin is considerably more rapid than presently published methods. Compositional studies show ADF to consist chiefly of lignin and polysaccharides. Correlations with the new fiber method and digestibility of 18 forages (r = —0.79) showed it to be somewhat superior to crude fiber (r = —0.73) in estimating nutritive valué. The correla-read more

The effect of interval between harvests and nitrogen application on the proportion and digestibility of cell wall, cellulose, hemicellulose and lignin and on the proportion of lignified tissue in leaf cross-section in two perennial ryegrass varieties
TL;DR: Effects of interval between harvests and time of year on herbage digestibility were due to effects on both proportion and digestibility of cell wall, particularly the latter, while cellulose and cell wall were less digestible in vitro than in vivo.

TL;DR: Division C-6 was established in 2000, but members associated with forages and grazinglands have been active in the Crop Science Society of America (CSSA) since its inception; 21 have served as President and many authored textbooks and comprehensive reference works.

Carbon and nitrogen forms in soil organic matter influenced by incorporated wheat and corn residues
TL;DR: This article investigated molecular-scale changes in soil organic matter (SOM) as incorporated wheat and corn residues decompose and whether those changes are correlated with soil nitrogen forms, and found that concentrations of organic-N in corn residues plus fertilizer treatment were significantly larger than those in wheat straw.

Thermal reactivity of rapeseed (Brassica napus L.) under different gas atmospheres.
TL;DR: Non-isothermal thermogravimetric method was applied to rapeseed to investigate its thermal reactivity under both individual dynamic atmospheres of nitrogen, steam, carbon dioxide and dry air, and under several mixtures of these gases (nitrogen+steam), (steam+dry air), and (Nitrogen+carbon dioxide+steam).

TL;DR: In this article, the effects of long-term continuous grazing on soil enzyme activities in relation to shifts in plant litter attributes and soil resources in an arid ecosystem, considering both spatial and temporal variations.
