Know your fields and your yield expectations. Soils where N rates have not kept pace with N removal will need to be built back up to increase their productivity. Here is a review of N product options and how they become plant-available…

Cover crops provide ground cover to avoid leaving fields bare. They provide weed competition, take up excess moisture, tie up nutrients at or near the soil surface so they’re not lost, and improve salinity. Nitrogen-fixing cover crops can increase soil nitrogen levels. Grassy cover crops act as “green manure”. All cover crops can reduce wind and water erosion of soil…

One challenge with boron is the hot water extraction (HW) soil test commonly used to test boron levels does not seem to be a reliable indicator of available boron. A 1999 study by Rigas Karamanos showed no relation between HW boron levels and canola yield, as the graph shows. Yet soil analysis continues to use the HW test for boron…

The ground is not frozen yet, which means growers and agronomists still have an opportunity to take fall soil samples. This is one of the best times to sample because……

Decisions on what variety, nutrient or crop input product to buy are improved with good data. When looking for data, here are a few clues as to the quality of the data set…

Soil sampling is good practice in the fall — whether crop was better or worse than you thought. Why fall? Growers often have more time in the fall than in the spring. And with results and recommendations in hand before winter, growers can use the winter months to plan their fertilizer programs for next year, to order fertilizer, and to…

Have you seen patterns like this? Potassium in swathed crop is mobile and if several rainfall events fall on the swath before combining, potassium will bleed out below the swath. Since a six-foot swath contains all the straw from a 30-foot or wider cut, the K is concentrated. K-loving crops following canola can find sufficient K below the swath, but…
