Advantages of Using Lime Sludge in Agriculture
Powerful pH Adjuster
Lime sludge from water treatment plants is as effective as agricultural lime in its ability to neutralize soil acidity.
Economic Substitute for Ag Lime
Lime sludge is a by-product of water treatment and is highly available in certain parts of the country, such as Ohio. When compared to the cost of agricultural lime, it is typically significantly cheaper on a ‘cost per acre’ basis.
Cost Effective Option for Water Plants
Water plants with limited storage capacity for lime sludge can rely on agricultural land application as a cost effective and sustainable solution. The cost to the plant for removal and land application is typically much less than the cost of other disposal methods, particularly landfill disposal. Most municipalities benefit from the agricultural value of the material and the demand is typically high.
