Participate in Developing an Irrigation Strategy for Niagara

The summer of 2016 was unusually dry across much of the Niagara Region. Prolonged dry conditions highlighted the need for access to irrigation water and the consequences of inadequate irrigation on crop production.

A number of grower organizations, working together with Niagara Region, were approved for a Growing Forward 2 grant to develop an Irrigation Strategy Action Plan for Niagara. The focus of this work is on farmland used for horticultural production, including grapes, tender fruit, nursery and greenhouse production, below the escarpment. The work is important for the future of your farm and your neighbours. Continue reading

Remember those energy bills from winter’s gone by? Have they got you thinking about doing some energy-efficient upgrades in your greenhouse?

The engineers at OMAFRA have been especially busy this year building GO-CALC – a tool to help estimate your energy use in the greenhouse AND how retrofits can help to make your greenhouse more energy-efficient!  The tool shows how those energy-efficient upgrades like energy curtains, new greenhouse coverings and boiler upgrades that you may already be planning for your greenhouse can help you save energy.
