The research suggests that improving pulse nitrogen fixation by targeting an increase in nodule numbers and nodule biomass could help improve long term cropping sustainability and reduce reliance on inorganic N fertilizer. In addition, developing pulse varieties with improved water-stress tolerance may improve the N-fixation...

Sensitivity of pulse crops to seedrow placed nitrogen, phosphorus and sulfur fertilizer products was lentil > pea ~ chickpea > soybean ~ black bean > faba bean. Overall and under good moisture conditions, a maximum of 10 kg N/ha rate as starter in the seedrow...

On sites testing low in nitrogen (N) fertility, flax yields were 39% higher with rates of 90 lbs. N side-banded per acre. Flax response to phosphorus (P) averaged 7% and rates of no more than 18 to 36 side-banded P2O5 per acre were justified. Phosphorus...

Over six years the highest wheat yields were achieved where a medium-high soil phosphorus (P) level (15 ppm) was achieved with an initial broadcast application of 327 pounds P2O5 per acre. On soils with very low P fertility, yields were four to five bushels lower...

To achieve 4R principles, placing ammonium phosphate fertilizer in a band, in or near the seed-row, at the time of seeding and at a rate that matches P removal by the crop generally provides the greatest P efficiency, long-term sustainability, and environmental protection for small...

Split applications of N usually provided the maximum yield and protein, particularly with Agrotain or SuperU. This study consisted of two experiments each conducted at five sites across western Canada at Brandon, Manitoba, Hallonquist (south of Swift Current), Saskatchewan, and Lethbridge and Lacombe, Alberta to assess...
