If a soil feels gritty when doing a "feel" assessment of texture, then an appreciable amount of _______ is present. - sand When performing a "feel" assessment of soil texture, the presence of a talc-like material on the hands indicates that an appreciable amount of ______ is present. - silt Soils developed in forest settings tend to have thinner surface horizons than those developed in grasslands. - true A soil horizon is a vertical section of the soil through its entire profile. - false An established turf that is too acidic can be easily topdressed with agricultural lime to lower pH. - false Which of the following parent materials is most closely associated with the Michigan sod industry? - organic deposits Rank the following soil particles from smallest to largest with 1 being the smallest and 3 being the largest. - clay (1), Silt (2), Sand (3) Michigan soils were mostly formed from what parent material. - glacial deposits The longer ribbon that can be formed by handling a moist soil, the higher the _____ content. - clay Generally speaking, soil is approximately 50% air plus water. (50% air & water and 50% mineral) - trueSoils developed in forest settings tend to be more fertile than those developed in grasslands. - false Warm-season turfgrasses can't tolerate a soil pH that is below 6.5 or above 7.2. - false Which of the following parent materials was formed by the forces of wind? - loess deposits Which of the following have the ability to store nutrients? Check all that apply. - - organic matter - clay Probing the soil to a depth of four to six inches is usually sufficient with turf soils. Question options: - true Soil structure affects the amount of macroporosity. - true Soil (macropores or micropores) can form a contiguous network that provides drainage and air movement. - macropores Soils developed in forest settings tend to be more acidic than those developed in grasslands. - true Which of the following is NOT a critical agent for soil formation? - none of these answers "Take a soil test first" is the number one rule of proper turf maintenance. - false Most of what eventually is deposited into our surface waters and causes problems is or are: -mercury -soil sediments -PCBs -Petroleum-Fertilizers - soil sediments Deposits of parent material must occur before soil formation can begin. - false Which of the following is not a critical agent for soil formation? - relative alkalinity Typical soil tests provide an analysis of the major and minor nutrients (except nitrogen) that are plant available only. - true Soils developed in forest settings tend to have higher organic matter content than those developed in grasslands. - false
