Amendment of Nitrogen and Phosphorus in Swine Manure by Nutrition -factsheet
Posted in: Environment by admin on | No Comments
A rapid expansion of swine production in prairie provinces increased the public awareness of the environmental concerns associated with swine manure – the odour and water quality being the main concerns. An excess nitrogen (N) and phosphorus (P) excreted in manure are responsible for adverse effects on water quality.
Manure from large swine production units with a limited land base can not utilize manure effectively as fertilizer resulting in storage and disposal problems. The new environmental regulations require nutrient management plans for swine farms.

Earthen Manure Storage Monitoring – PSC Elstow Research Farm
Posted in: Environment by admin on | No Comments
Introduction
Rapid growth in the Saskatchewan hog industry has caused an increase in environmental awareness among the public. This had led to more
stringent environmental standards being imposed on the construction of earthen manure storages. Most storages are now required to have a minimum 600-mm thick liner made of recompacted in situ soils. More extreme cases require a geotextile liner. These recommendations have resullted in a significant improvement over the unlined and uncompacted storages constructed in the past. Unfortunately, these improved liners have done little to alleviate public concern in some areas. In answer to this concern, a program was initiated to monitor solute migration through the liners of different hog lagoon storages throughout Saskatchewan.
Objectives
The main objectives of this project are to:
1. Determine changes in groundwater chemistry with depth over time,
2. Determine effectiveness of clay liners and clarify liner requirements, and,
3. Determine safe separation distance between EMSa

LABORATORY MEASUREMENT OF HYDROGEN SULFIDE AND SULFUR DIOXIDE RELEASES FROM SWINE MANURE OF DIFFERENT SOLID CONTENTS
Posted in: Environment by admin on | No Comments
Releases rates of hydrogen sulfide (H2S) and sulfur dioxide (SO2) from finishing swine manure of two
different solid contents and two initial manure accumulation days were measured under laboratory
conditions for one month. Manure was stored in reactors of 122 cm height and 38 cm diameter. The
reactors were continuously ventilated with 7.7 L/m of fresh air. Temperature was controlled at 20 A
