Plant respiration= evaporation cooling

Plant respiration = evaporation cooling.

Evaporation cooling = moist southern air moving north.


Water flows down hill… in ancient river beds under the sand.

Big Water and Grass

Big Picture

Data from the Soil Conservation Research project at McCredie during the summer drought of 1953 showed the corn crop exhausting the soil moisture to a depth of 3.5 feet under the fertilized soils. The equivalent of only 1.04 inches of water was left in that entire depth. Where the soil was not fertilized, the crop dried out the soil to a lesser depth. It left the equivalent of 4.5 inches of water in the upper 3.5 feet.
On the unfertilized corn, which took 14 inches of water from the soil, the yield was only 18 bushels per acre. It required 26,000 gallons of water to make a bushel of corn. On the fertilized soil with a
yield of 79 bushels, only 5,600 gallons of water per bushel were required.

The drought was a case of plant hunger rather than thirst.

Or simply, 4 times the crop yeild with one fifth the amount of water on fertile soil.

Biosolids and grass seed: more crop less water.

Over grazing = desert

Grass and Biosolid – We may want to consider the possibility that converting savanna grass lands to desert over the past 6,000 years of agricultural empire building is responsible for climate change effects rather than the reverse view that climate change causes deserts.

Uranium and grass

leave a comment »

Bacillus subtilis, sometimes called Grass Bacillus is a common soil bacteria.


We assessed the accumulation of uranium (VI) by a bacterium, Bacillus subtilis, suspended in a slurry of kaolinite clay, to elucidate the role of microbes on the mobility of U(VI). Various mixtures of bacteria and the koalinite were exposed to solutions of 8 × 10− 6 M- and 4 × 10− 4 M-U(VI) in 0.01 M NaCl at pH 4.7. After 48 h, the mixtures were separated from the solutions by centrifugation, and treated with a 1 M CH3COOK for 24 h to determine the associations of U within the mixture. The mixture exposed to 4 × 10− 4 M U was analyzed by transmission electron microscope (TEM) equipped with EDS. The accumulation of U by the mixture increased with an increase in the amount of B. subtilis cells present at both U concentrations. Treatment of kaolinite with CH3COOK, removed approximately 80% of the associated uranium. However, in the presence of B. subtilis the amount of U removed was much less. TEM–EDS analysis confirmed that most of the U removed from solution was associated with B. subtilis. XANES analysis of the oxidation state of uranium associated with B. subtilis, kaolinite, and with the mixture containing both revealed that it was present as U(VI). These results suggest that the bacteria have a higher affinity for U than the kaolinite clay mineral under the experimental conditions tested, and that they can immobilize significant amounts of uranium. http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6V5Y-4G7JXVH-3&_user=10&_rdoc=1&_fmt=&_orig=

Vast Sahara aquifers

with one comment

An international team worked on the verge of the Sahara to gather data on the ground and in the air, to be compared with imagery of the same region acquired by ESA satellites. The results will be used in support of an ambitious project to apply satellite remote sensing to improve monitoring and management of vast water aquifers concealed beneath the desert.
