Question

Under what conditions H2SO4 can be used for soil reclamation​

Answer 1

Answer:

The changes in exchangeable sodium and total dissolved salts due to the application of sulfuric acid and water to sodium-affected calcareous soils were studied for the purpose of establishing a convenient way of determining acid and leaching water requirements. Conventional methods which ignore the effect of sodium removed from soil exchange sites are inadequate for estimating amounts of acid needed to obtain a desired level of exchangeable sodium, especially at high acid application rates. Modified equations are presented which predict the changes in exchangeable sodium and total dissolved salts using essentially the same input data needed for conventional methods, and appear advantageous for estimating acid and leaching water needs.
