As the author himself once said, âIf I had to choose one of my books to live and not the others, I would never choose pedigree.â. Belgium's Master of Noir Nathaniel Rich December 3, 2010. For once, the focus was on Russert's work, not his pedigree.
Space farming. Space farming refers to the cultivation of crops for food and other materials in space or on off-Earth celestial objects â equivalent to agriculture on Earth. Farming on the Moon or Mars share many similarities with farming on a space station or space colony, but would lack the complexity of microgravity found in the latter.
Shifting agriculture, system of cultivation that preserves soil fertility by plot (field) rotation, as distinct from crop rotation. In shifting agriculture a plot of land is cleared and cultivated for a short period of time; then it is abandoned and allowed to revert to its natural vegetation while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds.
