Soil FRQ A) One chemical soil test we could do is a pH level test so we are able to tell what crops can grow in what areas. Other chemical tests include salinity‚ organic content (humus)‚ or the iron exchange capacity. One Physical Soil test we can do is pick up a handful of it and rub it together with our fingers to tell if it’s a soil heavy in clay‚ silt‚ or sand. Other physical tests include water-holding capacity porosity‚ moisture content‚ soil structure‚ or color. By completing these tests

Soil Microbe Lab Antibiotics are chemicals produced by substances that kill or inhibit the growth of bacterial cells (Hurney et al 2013). These microbes‚ such as bacteria found in the soil‚ may seem like they would be harmful to the human body because they attack cells‚ however they are very efficient at only attacking the bacterial cells. Actinomycetes are one of the more common groups of these soil microbes known to produce antibiotics. Antibiotics work because they target specific aspects
