SOIL AND PLANT ANALYSIS (1+1)

FAQ's

1.Narrate the effects of high partial pressure of CO2 in soil.
Answer: a. Partial pressure of CO2 affect solubility of Ca, Mg,Fe and Mn
b. Also affects specific conductance and exchange reactions

2. Give the critical Eh values of submerged soil at which O2 is reduced to H2O and CO2 reduce to CH4.
Answer: O2 to H2O -----> +380 to +320 and CO2 to CH4 ----> -200 to -280

3. Narrate the effects of submergence of an alkaline soil.
Answer: The effect of submergence of alkaline soil is increase in specific conductance by Ca and Mg.
