The moisture needs of aquatic biomass presumably are met in full because growth occurs in Hquid water, but the growth of land biomass often can be water-limited. Requirements for good growth of many biomass species have been found to be in the range of 50 to 76 cm of annual rainfall (63). Some crops, such as wheat, exhibit good growth with much less water, but they ate in the minority. Without irrigation, water is suppHed during the growing season by the water in the soil at the beginning of the season and by rainfall. Figure 17 depicts the normal precipitation recorded in the 48-state area during the normal growing season, Apdl to September. This type of information and the estabUshed requirements for the growth of land-based biomass can be used to divide the United States into precipitation regions. Regions more productive for biomass generally correlate with precipitation regions. It should be realized, however, that rainfall alone is not quantitatively related to productivity of land biomass because of the differences in soil characteristics, water evaporation rates, and infiltration. Also, certain areas that have low rainfall can be made productive through irrigation. Finally, some areas of the country that vary widely in precipitation as a function of time, such as many Western states, will produce moderate biomass yields, and often sufficient yields of cash crops without irrigation, to justify commercial production.  [c.31]
