Results and discussion

Details on results:
In pot tests, leaf scorches on plants were observed only when applied triple superphosphate contained 1.86-2.78% F-. Uptake of F-by plants was reduced by increasing soil pH by liming. Injury symptoms onFreesia hybridaleaves were observed on plants fertilized with triple superphosphate containing 1.0-1.6% F-.
