Note that the 'market feed' category includes primary crop products as well as crop by-products that are unsuited or undesirable for human consumption, such as distillers grains (a by-product of bioethanol production) and various oil-crop extraction by-products (e.g. oil seed meal or cake).
Sunflower seed is the chief oilseed crop; after extraction of the oil, the pulp is made into cattle feed.
The assessment encompasses the cultivation of the crop, the oil extraction stage and finally, the biofuel production stage.
We included hunting, drinking water extraction, crop production, fodder production, air quality regulation, carbon sequestration and recreational cycling.
The biogas potential of the residual fractions of four organically grown green crops after protein extraction was studied.
All cropping, downscaling and extraction of gridded climate values was done with the R packages raster[ 78], sp[ 79], and Rgdal[ 80].
Precipitation is the source for almost all soil moisture available for plant extraction by crops that are grown in rainfed cropping systems.
"Futures" markets actively wager on crop performance, natural resource extraction, and climate events compared to a background of previous seasons.
However, there are considerable difficulties in making precise estimates because of uncertainty both as crop production figures and extraction indices.
These vegetation formations are often overharvested as a result of overgrazing associated with fuelwood extraction and crop farming, as evidenced in northern Cameroon in the new cotton fields.
This black corner was removed during extraction by cropping out the large contiguous black section.
