|---|---|
| Heap on pad or yard | 30.8 |
| Field heap | 27.2 |
| Lagoon | 15.1 |
| Weeping-wall store | 8.2 |
| Below-ground tank | 6.3 |
| Above-ground tank | 5.6 |
| Strainer box | 1.1 |
| Covered shed | 1.1 |
a
Weeping-wall stores are large slurry lagoons that have a wall constructed of poorly fitting concrete slabs built across one end. Liquid manure with a very low dry matter content strains through this wall, leaving behind an easily transportable mass of dry biosolids. Strainer boxes, which use a similar principle, operate on a smaller scale than weeping-wall stores.
b
n, total number of samples analyzed.
