Growing barley is an important economic activity in many of Québec’s agricultural regions. According to data from Institut de la statistique du Québec, 73,000 ha were seeded in 2012, for a total production of 234,000 tons. In 2011, barley was grown on 3,175 farms, generating over $18 million in revenues. Therefore using fertilization charts that recommend doses that exceed the crop’s actual needs and the capacities of receiving environments to absorb them could cause serious agronomic and environmental impacts. So it was of some concern that the fertilization chart in Québec’s fertilization guide had been developed over the course of thirty years in cooperation with industry stakeholders and recommendations for the three main elements had not recently been tested in scientific field trials. In the case of nitrogen, recommendations varied significantly from 40 to 80 kg per ha. So for example, if based on this recommendation a surplus of 20 kg N per ha had been used on 73,000 ha, 1.5 million kilos of excess N would have been applied, with the associated environmental risks and economic loss. Therefore recommended doses of N, P, and K needed to be questioned, especially since cultural practices and fertilizers had changed since these doses were established. The grain industry needed more information on these recommendations given contemporary sustainable development objectives. Due to a lack of information, fertilization programs were not consistent among Québec producers, who did not necessarily consult the same information sources.

This project will develop a versatile tool that will allow to simulate the impacts of agricultural practices on soil organic matter.
The aim of this project was to gather data on the nutritional requirements of oats to better equip producers, extension agents, and other industry stakeholders.
