Full-scale slurry tank sampling: Effects of sampling strategy and sample storage on measured physical and chemical properties.

ABSTRACT: Accurate analyses of liquid animal manure (slurry) from full-scale slurry storage tanks are essential for effective nutrient management in agriculture. Inadequate or inconsistent sampling methods and improper storage conditions can lead to significant inaccuracies in nutrient analysis of slurry. This study evaluates the impact of different slurry sampling methods, storage types, and durations on the physical and chemical properties of slurry. Slurry was sampled using three different sampling methods in the same full-scale tank both before and after mixing. Samples were stored at 5°C and -18°C for different durations (1-24 weeks) to assess changes in physical and chemical properties of the slurry. The analyzed parameters were ammonium, total nitrogen, total phosphorus, sodium, dry matter, v
