Genetic Testing for ALS. Genetic Testing for ALS - ALS is directly hereditary in only 10 percent of families. The vast majority of ALS cases are sporadic, meaning that although there is likely a genetic predisposition involved, ALS is not directly inherited in a family. Although there is a genetic test for ALS, it is still quite limited. In 20 percent of families with inherited ALS, a change in the gene called SOD1 on chromosome 21 has been found, however, 80 percent of families with inherited ALS do not show a change in their SOD1 gene.
Granulated sulfur can play another important role in the establishment of a new lawn. Grounds Maintenance magazine says that turf grass grows best in soil with a neutral to lightly acidic pH. If a soil testing tool is reading a high pH number, your soil may be too alkaline for quick establishment of a lush lawn.
Why to Test: A pH level of 6.0-6.5 is important for the grass plant to get the most out of the lawn's nutrients. Anything less indicates acidity and lime should be applied to neutralize the lawn's acidity. Numbers greater than 6.5 indicate alkalinity and sulfur should be used to make the lawn more acidic.
