Various sampling ports are visible in this manure settling tank prototype. The tank was built to try to concentrate phosphorous in the bottom layer of the manure. The ports with open and shut valves allow researchers to sample and test manure for phosphorous concentrations at different depths. The concept will be tested this spring at five local hog farms. The tanks could make it easier to transport hog manure out of the Grand Lake Watershed.
