A comparison of methods for determining potassium in greenhouse soils



A comparison of methods for determining potassium in greenhouse soils



Agrokhimiya (4): 130-134



Various extractants (water, 0.1 N H2SO4, 1 N ammonium acetate and 0.2 N (NH4)2CO3) were used for determining K2O in greenhouse soils. Regression analysis showed fairly high correlations (r > 0.50) between the four methods tested.
