Question
1) Which of the following statement(s) is true for a soil with a low pH value? Select all that are true.
- The soil is likely to have low levels of exchangeable nutrients, such as, calcium, magnesium, and potassium
- The concentration of H+ in solution will be high
- The soil will be acid
- The concentration of exchangeable aluminum may be high, thus retarding root growth and microbial turnover
2)What is the dominant gas released from the soil when aerobic mineralization of the organic residues takes place?
- Oxygen, O2
- Carbon dioxide, CO2
- Ammonia, NH3
- Nitrogen, N2
3) Visualize a soil that is very shallow to bedrock and well drained. The soil texture is loam and the slope of the land is approximately 1-3%. Which of the following uses is most appropriate for this soil?
- Leaving it in native vegetation
- Building a home with a septic sysem
- Growing deep-rooted crops
- Planting a fruit orchard
Explanation / Answer
1) All the choices are correct.
2) In aerobic mineralization of organic matter, carbon is used up and Carbon dioxide CO2 gas is released.
3) the soil must be used for building purpose as the soil is shallow to bedrock and well drained with low slope. The construction will be stable. Although loam texture is suitable for vegetation and agricultural purposes, deep rooted crops and fruit orchard will not be suitable for the region as the bed rock depth is in sufficient
