Notes:
A system for rapid freezing and containment of pasture and forage samples in the field is described. Core temperatures of pasture samples of 2–5 kg mass can be reduced to below 0°C in a few minutes using liquified carbon dioxide in the ratio of 1 to 2 kg carbon dioxide to 1 kg of green plant material. Changes in the pH of the plant extract were very small (ca. 0 1 pH unit). The system is especially suitable for use in areas remote from normal laboratory facilities, where rapid freezing of herbage samples is essential.
