Base cations were determined by extraction with 1 N ammonium acetate, trivalent aluminum with 1 N KCl, and crystalline iron by citrate - bicarbonate. K very high. Site on Ag Station. Mg exceeds Ca. Pohnpei Series Slope K Fact.
Many soils have steep slopes and so clearing generates significant erosion hazard.
Most soils are highly weathered and have high to very high phosphorous fixation capacity. Most have little ability to furnish potassium to the system. Many are highly acid and may create aluminum toxicities for many types of crops. Liming rates are variable however. Organic matter is easily lost and should be diligently maintained.
