Lime costs more on the coast than in the Willamette Valley typically 25 to 30 more/ton Forage grass yield increase from lime application varies from 250 to lb/a It is generally understood in the scientific community and in commercial farming industries that soil pH plays an important Lime consumption can however be very high especially for ores with high pyrite content and/or when flotation is carried out in seawater For some South American copper ores pH values as high as 115 are needed to depress pyrite and lime consumption up to 5 kg/t of ore is reported
