The texture of soil was calcareous cinnamon soil with neutral or
alkalescent PH, relatively higher mineral matter, organic matter content, humus layer, and fertility.
The
alkalescent site is the active site of the carbonyl sulfide's hydrolysis.
pH is in the
alkalescent domain (8,06 / 8,16) pH units; the total alkalinity is (3 / 3,5) mechiv/l.
Root H+ effluxes: Generally, bromocresol purple exhibits yellow color under acid conditions and purple color under
alkalescent conditions, respectively.
