Preliminary Evaluation of Point-injection for Application of P & K to Forage Grasses in Southern Alberta

Greenhouse study assessing the benefits of point-injection for improving P and K use by forage grass. Results will be used to design of future large-scale field experiments.

IPNI-1990-CAN-AB2

Description. Improved fertilizer use efficiency has been observed in corn and wheat when fertilizer is applied by point-injection. Because point-injection places fertilizer directly into the rooting zone with minimal crop and soil zone disturbance, it may be ideal for fertilizer placement in perennial forages. This greenhouse study is determining the benefits of point-injection for improving P and K use by forage grass. Read more
