Input Parameters Used

Soil pH

Measures soil acidity/alkalinity. Lower pH indicates more acidic soil requiring lime application.

Buffer pH (BpH)

Indicates soil's resistance to pH change. Essential for determining accurate lime requirements.

Organic Matter & Clay

Higher OM and clay content increase buffering capacity, affecting lime requirement calculations.
