-Viruses are 10 to 100 times smaller than bacteria-Viruses need a living host; bacteria can grow on non-living surfaces-Antibiotics don't work on viruses, because antibiotics interfere with cellular processes that viruses do not perform.Differences Between Bacteria and Viruses are: î î î.Are small DNA fragments-Each fragment carries between 2 and 30 genes-Some plasmids have the ability to move in and out of the bacterial chromosome-Plasmids are not needed for the cell's growth or reproduction, but can cause disease or can protect the bacterium from things like antibiotics.
Check out this page for a simple soil content test. The soil's pH rating is also important. This rating tells you the relative acidity and alkalinity of the soil (this page explains the concept). The ideal pH level is around 6.5 or 7, but levels vary between different grass species and climate conditions. You can find out your soil's pH level with a home test or a professional test. If you need to substantially increase the acid level, add sulfur.
Correct soil pH. Soil pH level in your organic lawn is the measure of itâs acidity. Actually, itâs the levels of hydrogen ions but we wonât go that deep on this page. Lawn pH is based on a scale from 1 to 14 with 7 being neutral. A pH of soil below 7 the lawn is considered acidic and above is basic. Most turf grass, like a pH level at 6.4 to 6.8 which is slightly acidic. Most nutrient availability to the grass plant is optimum right around neutral, which is 7. So you can see having the correct levels is critical.
