C&H Hog Operation

Farm established in early 2013 Owners voluntarily approached Newton County Extension Office

for assistance

Capacity for 6,500 hogs; operating at 2,500 pigs

Approach & Tasks

Developed monitoring network at field, farm, & watershed scale to

determine impact of farm operations on Big Creek water quality

Evaluate manure management system & nutrient management plan Characterize soil chemical properties on 3 application fields using

grid soil sampling every 2 years

Monitor slurry holding pond leakage with inceptor trenches Minimum of 5 years monitoring needed

  • No build-up of P in surface soil from slurry application
  • Soil P accumulation in cattle feeding & loafing areas
  • No evidence of slurry holding pond leakage to date
  • No consistent water quality trends to date
  • Continue to provide transparent, unbiased science for

landowner & State to make decisions
