Supplemental Forages to Plant in July After Wheat

Jul 01, 2022

By Mark Sulc and Bill Weiss

Some producers may be considering planting a supplemental forage crop after winter wheat grain harvest for various reasons. Some areas of the state are becoming very dry. In many areas, the wet weather this spring resulted in ample forage supply, but good to high-quality forage is in short supply because of the wet weather that delayed harvesting until the crop was mature, or it resulted in rained-on hay that lowered quality.

forages

The table below summarizes options for planting annual forages after wheat harvest.

Species	Comments
Corn plant silage	Highest single-cut forage yield potential of all choices. Silage quality will be lower than normal planting dates. The risk is getting it harvested at the right moisture for good fermentation.
Forage sorghum Sorghum-sudangrass Sudangrass	Best harvested as silage. Brown midrib (BMR) varieties have higher digestibility and are best for growing animals and lactating cows; however, conventional varieties are okay if BMR seed is not available. Can produce 3-4 tons of dry matter/acre. Potential high nitrates under drought conditions. Risk of prussic acid (hydrogen cyanide gas) if frosted.
Soybean silage	A reasonable alternative to replace alfalfa forage. Check seed treatment and herbicide labels, many restrict forage use.
Teff grass	Best suited to beef and sheep; lower yield than sorghum grasses. Can be harvested as hay or silage.
Millets	Best suited to beef and sheep; many produce a single harvest. Best harvested as silage. Potential high nitrates under drought conditions. Pearl millet has no prussic acid after frost damage.
Mixtures of annual grasses with soybean	Best harvested as silage. Mixtures of sorghum grasses or millets or even oats and spring triticale with soybean are feasible and soybean can improve forage quality characteristics.

The forage grass options all require adequate nitrogen to maximize yield potential, either as fertilizer or manure (about 60 lbs of actual available nitrogen per acre). Check any potential herbicide restrictions from the previously planted crop and consider herbicides used after wheat and before planting these annual forages.

Chopping and ensiling or wet wrapping are the best mechanical harvest alternatives for most of the options listed. Wilting is usually necessary. Storage and harvest costs are greater, and fermentation quality can be poor with crops less than about 30% DM (greater than 70% moisture). Ideally, silage should be left undisturbed for at least two weeks to allow the forage to reach stable fermentation. If forage is needed sooner, consider daily green chopping of forage or wet wrapping individual bales for feeding until the silage is ready. Except for Teff, dry baling any of the listed forages is a challenge. Work with your nutritionist to incorporate these alternative forages into properly balanced rations.

In addition to these options, Italian ryegrass or oats can be planted in early August, if soil moisture is adequate. They will produce forage into the autumn months, and Italian ryegrass will likely survive the winter and produce forage next spring and early summer depending on the variety planted. They are suitable for ensiling or wet wrapping or grazing in the autumn. Brassicas can be planted in early August as well, but they are only suitable for grazing in the autumn, not for mechanical harvesting.

Video: Western Canadian Agriculture: Hard Times Made the World's Best Farmers

Western Canadian agriculture produced the most advanced farmers in the world not through abundance but through adversity. The crow rate fell. The wheat price went nowhere. The brown envelopes stopped.

When the subsidies disappeared, the bad farmers left and the good ones stayed. And the ones who stayed could not just grow wheat anymore. They started growing lentils and canola and peas and flax and faba beans. They built crop rotation. They got serious about agronomy because there was no government backstop. That process produced the Western Canadian agriculture Dennis Bulani describes in this clip: the most advanced, most educated farming culture in the world.

His contrast with Iowa corn and soybean farmers is sharp. At a DeKalb farmer meeting in Okoboji, Iowa, he asked what crop rotation they ran. Beans on corn stubble, corn on bean stubble. How do you fertilize? The co-op agronomist handles it. Have you considered other crops? No need. We make so much money on corn and soybeans. Western Canadian agriculture was never allowed that comfort. And now those Iowa farmers are watching soybean markets lock up with China and corn prices slide, and they do not have the agronomy knowledge or the research base to pivot. Western Canadian farmers adapted on a dime because they had done it before.

Dennis also makes the case that Western Canadian agriculture keeps adapting in real time. Low commodity prices over the past year have pushed growers to look seriously at precision spot-spray technology. He knows a neighbor who bought a sprayer with the seeing-eye system and sprayed only 80 out of 320 acres. As a chemical retailer Dennis acknowledges that will affect his sales. He supports it anyway, because if it advances Canadian agriculture and makes farmers money, that is a good outcome.

The lesson Dennis draws from the tale of two farms: continuous improvement is the only durable strategy. When canola was $22 a bushel some growers went to Arizona instead of the Crop Production Show. When the price came down those same growers came back to the research and the discipline. Products do not go on Rack Petroleum's shelves unless they pass a replicated trial first. That is what Western Canadian agriculture built through hard times: farmers who do the work whether the times demand it or not.
