Organic hay – is it right for you?

February 8, 2017
Glenn Shewmaker
With the low hay prices of 2016, some producers may be thinking of trying to get into the organic hay market. Organic farming systems rely on practices such as cultural and biological pest management, and virtually prohibit synthetic chemicals in crop production and antibiotics or hormones in livestock production.

What is your cost of hay production this season?

December 1, 2016
Glenn Shewmaker
Is the market price for hay lower than your cost of production? Do you know your cost of production? I suspect many of us have not calculated it for a while. I recently went through the process of updating a budget for irrigated alfalfa hay in southern Idaho.

How good is your hay?

October 13, 2016
Glenn Shewmaker
Everyone should have inventoried, sampled and tested each lot of hay by now. Regardless if you market your hay or use it yourself, a forage inventory complete with quality tests is essential to making informed decisions. A test is a no-brainer for marketing purposes. How do you know what each lot is worth without a test?

Fall alfalfa cutting management is critical

Fall energy management in alfalfa

August 26, 2016
Glenn Shewmaker
September is probably the most critical month for alfalfa’s stand health and next year’s yield. Alfalfa will be in an energy-deficit situation after cutting until it reaches 6 to 8 inches in height.

Cut hay or spray – 7 points to consider in alfalfa pest control

May 20, 2016
Glenn Shewmaker
We have some effective pesticides, but when do you need to apply them? The answer for many of us procrastinators is 10 days to two weeks ago. Rather than adding to a problem of selection for pesticide-resistant insects, maybe a better plan is to just cut the forage early and then monitor for continued problems.

PEAQ stick

Predicting alfalfa forage quality with the PEAQ stick

March 17, 2016
Glenn Shewmaker
The quality of alfalfa hay is determined by its maturity at cutting, environmental conditions prior to and during harvest, and by handling and storage processes post-harvest. Environmental conditions vary from year to year and day to day, so calendar date is not a good predictor.

Are you playing catch-up with alfalfa nutrition?

February 19, 2016
Glenn Shewmaker
Early spring is the time to get out the soil probe and sample for soil fertility in preparation to provide adequate plant nutrition for alfalfa and other forage crops.

Clover root curculio in alfalfa

January 28, 2016
Glenn Shewmaker and Erik Wenninger
The clover root curculio (Sitona hispidulus) is a pest of alfalfa and clover that occurs throughout the U.S. Adults may cause injury by feeding on the foliage of fall-planted alfalfa, but the primary concern is damage caused by larvae feeding on the roots, which can reduce yield, quality and stand persistence in forage alfalfa.

Working in dormant alfalfa fields

January 12, 2016
Glenn Shewmaker
For convenience or necessity, we sometimes want to work in or make applications in our alfalfa fields during the late fall, winter and early spring. Alfalfa is most dormant then, and it is a good time to apply fertilizer, compost or manure. Sometimes we need to use herbicides that are supposed to be applied while alfalfa is dormant.

Hay tarps vs. sheds

June 24, 2015
Glenn Shewmaker
In humid environments, the need to cover hay is obvious, but what about arid environments? My opinion is: Hay has too much value to not cover, even in arid environments. It only takes one thunderstorm or the accumulated rain and snow in fall and winter to cause problems.
