Hint:

Match each test with the nutrient it estimates—Bray for P, Kjeldahl for N, and flame photometry for K.

Answer 1

The Correct Option is D

Kjeldahl method determines nitrogen. Bray P1 is used for phosphorus. Ammonium acetate is for exchangeable K and ammonium. Flame photometry detects K and Na in solutions.
