Liners support nutrient management planning by giving operators a clearer understanding of how much manure or wastewater is actually being stored over the winter. When a lagoon or pit is unlined, soil seepage can cause unpredictable losses that make it difficult to estimate the true nutrient content available for spring application.
A lined system keeps the material contained, making sampling and volume tracking more accurate. Improved accuracy helps producers match application rates to crop needs and stay within regulatory limits. By preventing leakage, liners also reduce the risk of unplanned runoff events that could disrupt a carefully developed nutrient plan.
