Description |
An experiment was conducted during 2006–07 to study the fluoride enrichment in soil as well as crops after phosphogypsum application in the sodic soil and compared with the mineral gypsum treated soils. It was found that the addition of phosphogypsum increased both the total water soluble fluoride (Ftw) and total CaCl2 extractable fluoride FtCa in the sodic soil over mineral gypsum treated fields. The Ftw in 0–15 cm of the soil layer varied between 3.2 and 3.9 mg/kg, whereas total CaCl2 extractable fluoride varied between 5.6 and 9.0 mg/kg. The total water soluble fluoride were positively correlated with total fluoride concentration (r=0.76, P
