Deep-banding phosphorus a potential yield booster
Bourgault is placing phosphorus deep in the soil to see if plants can access it throughout the season
Placement called vital in phosphorus application
Three-year study in Saskatchewan investigates the influence of phosphorus fertilization practices on crops, soil and water
The 4Rs of nutrient stewardship for phosphorus are important management considerations, but placement is especially noteworthy, said a leading soil fertilizer specialist. “Applying the 4Rs (right rate, right source, right placement, right timing) will enable you to get the best benefit out of your phosphorus fertilization with minimal impact on the environment,” said Jeff Schoenau, […] Read more
Phosphorus concerns force conservation focus
It’s well known that the world is running out of phosphorus. Geologists and scientists argue about when it will happen, possibly 100, 200 or 600 years from now, but most accept that the Earth has a limited supply of phosphate rock. Considering how phosphorus is a critical nutrient for plant growth, it’s surprising how little […] Read more
Farming isn’t rocket science, or is it?
Farming isn’t rocket science. It’s much more difficult than that. Understanding the complex workings of soil and plant requires time, effort and an understanding that conditions are constantly changing. Senior adviser Tim Eyrich of Agri-Trend put it this way at a March 2 regional meeting in Lethbridge. “What we do is harder than rocket science. […] Read more
No-till gets credit for boosting sulfur in soil
Half of sulfur remains in the straw in the field after harvest and returns to the soil as the residue breaks down
No-till production methods have boosted soil organic carbon levels and increased the soil’s nutrient supplying capacity, including its ability to supply sulfur to prairie crops. University of Saskatchewan soil scientist Jeff Schoenau said during a presentation at a recent farm show in Saskatoon that only about half of sulfur used by the crop is removed […] Read more
Will algae become the next big thing in fertilizer?
Nitrogen from algae | On a farm in New Mexico, algae are fed and cared for like livestock
MORIARTY, N.M. — The next source of fertilizer might be growing in a tank in New Mexico. All it takes is low-cost plant food, water and sunlight. Researcher and entrepreneur Calvin Hildebrand is rolling the dice on a natural source of nitrogen fertilizer from algae. He’s conducting his work on old Route 66, in the […] Read more
