- The relative humidity in pore spaces is high in soils in tropical areas but low in desert soils. True or false.The air in soils is normally higher in CO2 and lower in O2 than atmospheric air. TRUE OR FALSEContinuous movement of elements and compounds that make up nutrients through air, water, soil, rock, and living organisms.
- Soil organic matter (SOM) samples have charge that is pH-dependent, and measurements for the cation-exchange capacities (CECS) of soil organic matter average around 150 cmol(+)/kg SOM at neutral pH. Meanwhile, smectite clay minerals have CECS that average approximately 100 cmol(+)/kg clay. Since these two phases are the dominant contributors to soil CEC, we can use SOM content and smectite content (if we can measure it) to estimate total soil CEC. What would be your estimate for the total CEC (in cmol(+)/kg soil, to the nearest 0.1 cmol(+)/kg soil) of a soil that contained 3.28 % SOM and 1.0 % smectite clay by weight?%OM pH EC Ca2+ Mg2+ K+ Na+ Al3+ H+ % dS/m cmolc/kg soil cmolc/kg soil cmolc/kg soil cmolc/kg soil cmolc/kg soil cmolc/kg soil 2.7% 7.6 4.5 19 13 10 3 1 4 Is this soil affected? If so, what type? - saline - sodic - not salt affected - saline-sodicImagine you are testing water samples from a local pond for pollutants. Your lab instructor sees the results of your dissolved oxygen test and remarks that your water sample has the same dissolved oxygen level as water found near the seafloor of a dead zone. What is the dissolved oxygen level of this water sample? 650-700 ppm 350-360 ppm 80-90 ppm 7-9 ppm 2-3 ppm
- Plants absorb several ions and water from soil. For this reason, it is necessary for the soil to have a pH value at the range of 6.0 – 8.0. Again, if the p4 is less than 3.0 or greater than 10, then the beneficial microbes of the soil die. Normally rainwater is slightly acidic, its p# value is 5.5. During thunderstorm nitrogen and oxygen of air react to form nitric oxide, which is oxidized to form nitrogen-dioxide. This nitrogen-dioxide reacts with water vapor and forms nitrous acid and nitric acid. Acid-rain occurs because of it. 2NO2+ H2O → HNO2+HNO3 Examination of soil in a region of Rajshahi revealed that its p" value was 6.43. Nitrogen-dioxide is formed in the air because of thunderstorms, and its concentration is 0.297 ppm. What will be the difference between the p" value of the soil after rain and the lowest standard pH value ?Soil pH influence the availability of soil nutrient elements TRUE OR FALSEExplain how these factors: the size of bioaerosol, inspiratory flow rate, flow pattern, inhaled volume, respiratory rate influence the respiratory degration of bioaerosols.
