Physiological groups of soil microorganisms, total C and N and available nutrients were investigated in four heated (350 °C, 1 h) soils (one Ortic Podsol over sandstone and three Humic Cambisol over granite, schist or limestone) inoculated (1.5 μg chlorophyll a g−1 soil or 3.0 μg chlorophyll a g−1 soil) with four cyanobacterial strains of the genus Oscillatoria, Nostoc or Scytonema and a mixture of them. Cyanobacterial inoculation promoted the formation of microbiotic crusts which contained a relatively high number of NH4+-producers (7.4×109 g−1 crust), starch-mineralizing microbes (1.7×108 g−1 crust), cellulose-mineralizing microbes (1.4×106 g−1 crust) and NO2− and NO3− producers...

Profound changes are now occurring in the Colorado River Basin. New societal demands for water are on a collision course with vested legal rights and past commitments. The exploitation of fossil fuels in the area poses great problems for the traditional paramount concerns of reclamation and agriculture. The ' law of the river ' is actually a composite of many statutes, compacts, court decisions, contracts, regulations and administrative rulings. Generally speaking, the flow of the Colorado River is divided among users on the basis of beneficial consumptive use. The allocation system operates at four levels: international, interregional, interstate, and intrastate. Legal problems on the river are partially the function...
