Science is not infallible and it should not always inform farming policy

John Gibbons of An Taisce tells us that we must use science to inform policy (Irish Examiner, January 11).

I don’t trust scientists and academics because 50 years ago at night agricultural classes were were told about phosphate fixation in the soil and how it renders the phosphate unavailable to the plant.

Now they tell us that it is locked out of the soil and polluting our rivers and lakes.
