Understanding phosphorus, part 3: Developing fertilizer recommendations

Agronomy Management: It’s important to have adequate P close to the seed during the first six weeks of growth

Part 3 of 3. Prairie farmers spend over $1 billion annually on phosphate fertilizer; these three articles will hopefully assist with a better understanding of how soil P functions in soil, soil testing for P and then how to develop wise phosphate fertilizer recommendations.

Understanding soil phosphorus, part 1

Agronomy Management: Rotations and fertilizer management have dramatic effects on pools of organic and inorganic P

Farmers and agronomists are very aware that phosphorus (P) is an essential element needed for optimum crop production in Western Canada. Most soils used for annual crops in Western Canada are very low, low or medium in plant-available soil P and are responsive to added P fertilizer. As a result, phosphate fertilizer use is second […] Read more

Feeding dry fields

Prairie farmers find more than one way to optimize fertilizer efficiency, whether in dry growing seasons or in any growing season

Farmers and crop consultants in Western Canada have slightly different approaches to manage weather-related fertilizer application risks. With variable moisture, do you apply the full amount at seeding and hope for rain — or find another way? Most producers contacted by Grainews opt for some version of split fertilizer application when facing dry growing conditions […] Read more
