Liquid manure management

On this page, you’ll find information on storing liquid manure, how to size liquid manure storages, and links to the necessary regulatory information. 

Liquid manure storage

A critical characteristic of all farm operations is having enough storage capacity for manure and incidental by-products (ex. flush water, wasted feed, etc.). In B.C., it is recommended that farms have 6 months of storage capacity. However, 7 months of storage may be needed if the farm is located in a colder climate that reduces the manure application period.

The factsheets below describe important manure storage attributes that assist in meeting the Code of Practice for Agricultural Environmental Management (AEM Code). These factsheets discuss storage location, design, and sizing, among other things.

Solid/liquid separation

Solid/Liquid separation utilizes a piece of equipment, such as a screw or roller press, and separates manure into a solid and liquid fraction. There are some tangible benefits from implementing solid/liquid separation on-farm:

  • Liquid storage volume is maximized by removing the solids
  • Less agitation is required at pump out
  • Minimizes pumping issues
  • Less expense when hauling manure solids to fields due to reduced volume

The following report discusses different manure treatment technologies such as solid/liquid separation and bedding masters, and how such technologies can affect farm operations
