Did you know that a review of Ontario phosphorus (P) and potassium (K) fertilizer guidelines was undertaken? The work looked at crop responses to P and K for corn, soybeans, winter wheat and alfalfa from 368 trials conducted over the last several decades. It compared most economic rates to current Ontario fertilizer guidelines as found […]

Forage soybeans are not normally recommended as an emergency forage. Forage soybean production has a steep learning curve. Successful producers started with a small acreage and took several years to learn how to manage this crop. Whole unroasted soybean seeds pose a risk of ammonia toxicity. Limit to 2-4 lbs/head/day. Protein exceeding animal demand will […]

Regrowth rates of hay fields following a cut and pastures following a grazing event is dependent on rainfall. Areas that received below-average rainfall may experience slower regrowth. Producers looking to buy or sell hay are encouraged to check out the new and improved Ontario Hay Listings website Southwest According to AAFC, most of the area […]

April 2021 Forage Report

Winter of 2020-2021 was mild. Although snow cover was less than normal, there were relatively few thaws. A rapid thaw in early March melted most of the snow. The warm temperatures persisted for a few days, allowing perennial forages to break dormancy. Dry conditions throughout March with warm days and cool nights provided a window […]

Alternative Forages to Silage Corn

Silage corn is grown to provide energy and fibre in a ration. It has very high yield potential. In addition to breaking corn rootworm lifecycles, alternatives to silage corn need to offer similar yield and nutritional value (Table 1). Producers should consult a livestock nutritionist to ensure rations are properly balanced. Table 1. Typical nutritional quality and […]

Photo: It is impossible to tell by looking at frost-damaged sorghum-sudangrass what the prussic acid levels may be. Silage Corn In fields where rootworm Bt hybrids have been used for three or more consecutive years, resistance among corn rootworm populations is suspected. Producers can no longer rely solely on Bt rootworm hybrids for protection against […]

Managing Jointing and Non-Jointing Grasses

Christine O’Reilly, Forage and Grazing Specialist, OMAFRA Grass doesn’t just happen and not all species grow the same way. Understanding how different grass species grow enables producers to make good management decisions that maximize forage production in their hay fields and pastures. Jointing and non-jointing grasses respond differently to cutting, which directly affects productivity and […]

July 2020 Forage Report

Alfalfa plants exhibiting characteristic hopperburn: a yellow V shape on the tips of the leaves.

Photo above: Potato leafhopper damage (called “hopper burn”) is frequently mistaken for insufficient water. To maximize the forage yield of fall cereals next spring, research from New York state suggests planting fall rye or winter triticale 10-14 days before the optimal winter wheat planting date (Figure 1).   September 1st is the deadline to report […]
