The relative alkalinity or acidity of a soil can be measured against a scale which has become accepted by gardeners and is known as the pH scale. This runs from ph0 to pH14 with pH7 as neutral. Plants grow in soils within the range of pH4.5 to pH7.5. A soil between pH5.7 and pH6.7 is ideal for the majority of plants. Above this reading the soil is too alkaline, and below it, too acid. A chalky soil has a high calcium (alkaline) content and will, therefore, have a high pH reading.

pH is a measure of the acidity ("sourness") or alkalinity ("sweetness") of soil. The scale ranges from 1 to 14, but few soils are more acidic that 5 or more alkaline than 9. A pH of 7 is perfectly neutral, but most plants grow best when the pH is a slightly acidic between 6.5. Soils in areas with low rainfall tend to be alkaline. Where rainfall is high, soils are more often acidic. This happens because rainfall gradually washes calcium from soil. See similar questions...

Organic RAW eggs are slightly acidic (have to be cautious about salmonella, so I would not recommend eating them). Cooked eggs are more acidic. Raw (unpasteurized) honey has a near-neutral pH. But, as with any raw animal product, microbial concerns need to be taken into consideration. Pasteurized honey is slightly acidic. I’d recommend raw agave nectar in place of honey. Just Juice markets its 100% pure organic pomegranate juice. I notice it is pasteurized. See similar questions...

It is not quite a "round Scale" but Roy Johnson has written "Dial.pm" for round dial (or speedometer) -like settable widgets. It is available from: http://sun20.ccd.bnl.gov/~ptk/archive/ptk.1995.08/0431.html or http://w4.lns.cornell.edu/~pvhp/ptk/etc/Dial.pm As well as from the Contrib/ sub-directory of your Perl/Tk build directory.

ATPM uses the following ratings (in order from best to worst): Excellent, Very Nice, Good, Okay, Rotten. See similar questions...

SPECjAppServer2004 has been designed and tested with both scale-up and scale-out configurations. The design of the benchmark does not limit the scaling in either way. How well it scales in a particular configuration depends largely on the capabilities of the underlying hardware and software components. See similar questions...

We like to call it "mini-figure scale (i.e. the little LEGO? people), but to be honest there really isn't a scale in unit of measure per say. Some people say that one LEGO? stud equals one foot, but that means that the trains are not to scale unless you make them wider, longer, etc. See similar questions...

The degree of alkalinity of a solution is measured in terms of a value known as pH, which is tie negative logarithm of the concentration of hydrogen ions. On the Ph scale, which ranges from 0 (acid) to 14 (alkaline), a solution is neutral if its pH is 7. Our body pH should be slightly alkaline and should be approximately 7.5 measured via saliva or urine. Blood pH should be 7.365 ideally. See similar questions...

The acidity and alkalinity of a substance is referred to as its pH value. A neutral substance has a pH of 7, a substance with a pH above 7 is considered alkaline and a substance with a pH below 7 is considered acid. The term acidosis is used to describe a state of excess acidity in the body fluids whereby the term alkalosis describes a state of excess alkalinity. See similar questions...
