The operational-based treatments
contained considerably higher levels of all elements:
16.80 g N and K per seedling and 50.40 g P per seedling. The MAP
treatment was designed to deliver comparable P (50.96 g per seedling),
which corresponded to 10.78 g N. Although the TSP treatment
contained no N or K, P levels (50.85 g) were comparable to
the operational treatment.
