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.
If your soil needs to be more acidic, sulfur may be used to lower the pH if it is available. To reduce the soil pH by 1.0 point, mix in 1.2 oz of ground rock sulfur per square yard if the soil is sandy, or 3.6 oz per square yard for all other soils.The sulfur should be thoroughly mixed into the soil before planting.enerally, soils in moist climates tend to be acid and those in dry climates are alkaline. A soil with a pH lower than 7.0 is an acid soil and one with a pH higher than 7.0 is alkaline. The soil must be adjusted to suit the plant which will occupy that area if it is not already within that plants requirement range.
