Applying Thomas Phosphate
When is the best time to apply Thomas phosphate slag on orchard land?
As Thomas phosphate is slowly soluble, it can be applied at any time
during the rainy season without danger of loss, and for the same fact,
it should be applied early during the rainy season in order to be
available to trees during the following summer's growth. It ought,
perhaps, to be added that other forms of phosphate have largely
displaced slag during the last few years in the United States, other
forms being more available.
