Managing Separate Manure Fractions on Dairy Farms Project

OBJECTIVE - AAFC requires a Contractor to provide and operate a Manure Spreader which will be used to extract and apply liquid manure as described in herein.

PHASE 1 AAFC will identify a maximum of 25 farm sites which will be located in the eastern Fraser Valley in British Columbia. Sites will be preferably within 25 km of the town of Agassiz. At each farm site, one (1) or two (2) manure extraction locations will be selected from a primary manure storage pit or tank. Additional extraction locations may be selected for farms with multi-cell storages.

Manure from each location will be extracted separately from one (1) to five (5) depth zones as per Approach and Methodology - Phase 1 described herein.

All sites will be sampled at least once with some being sampled two (2) to three (3) times over a two (2) and a half year period. Work will occur when farm manure storages are at least 75% full. It is envisioned that most work will occur during the winter of 2014. However, some sampling will also occur at other times of the year and in other years, depending on project criteria.

Sampling dates will be coordinated by the Project Authority and the Contractor will make every effort to accommodate the schedule.

The Contractor will be required to : 1. Perform site assessment to ensure site is safe 2. Operate a manure spreader to extract bulk liquid manure using the Approach and Methodology - Phase 1 described herein.

PHASE 2 AAFC will identify a maximum of six (6) farm sites which will be located in the eastern Fraser Valley in British Columbia. Sites will be preferably within 25 km of the town of Agassiz. At each farm site, one (1) grass field and one (1) corn field will be chosen for manure applications. Within each field various manure application treatments will under taken, involving shallow injection of thin liquid dairy manure fraction and surface application of agitated un-separated raw dairy manure. Applications on grass fields will be done two (2) to three (3) times throughout the growing season, while the applications on corn fields will be done only once prior to spring corn planting.

Dates for manure application will be coordinated by the Project Authority and the Contractor will make every effort to accommodate the schedule.

AAFC will select the manure storage locations for manure source; the required pumping depth to extract the manure; the appropriate field site / treatment areas, identified by field stakes and / or GPS coordinates, and the target application rate(s) within a range that is feasible for manure spreader tanks.

AAFC will also determine the appropriate application tool, either trailing hose or shallow injector, to be used for each manure treatment and the Contractor will ensure that application tool is mounted to the Manure Spreader prior to arriving at the Farm.

At each site the Contractor will be required to : 1. Perform site assessment to ensure site is safe 2. Operate a manure spreader to extract and apply manure using the Approach and Methodology - Phase 2 described herein.
