As temperatures heat up and time passes, plants progress from the vegetative phase to the reproductive phase of growth. In this window of time, the plants are allocating energy to the production of a flower. After flowering, energy is allocated to seed fill. While the focus is shifted to reproduction, leaves and stems become less nutritious and accumulate fiber. The increase of fiber in the stems and leaves helps support the flower and seed head as the plants become heavier.
As fiber increases, the forage becomes more difficult for animals to fully digest. Animals eat less because it takes longer for food to pass through their digestive tract. The greater the amount of fiber in the forage, the lower the nutritional value for livestock, thus the more they must eat to maintain weight. When the rate of consumption cannot adequately supply nutrients to the animal, weight gain stalls and production ability of the animal decreases.
In simple terms, if the weather allows, harvest should be accomplished before grasses and legumes begin producing seed. Having good weather in May gives the hay maker the opportunity to achieve a timely first harvest and improves the odds of getting good results in subsequent cuttings in the same hay season.
While there are numerous other factors that go into the production of high-quality hay, having good weather on your side is critical for success. Producers must also pay attention to soil fertility, drying time, and hay storage to maximize both quality and quantity.
Making hay in May means we are off to a great start of hay season.
Please be safe out in the field and avoid rushing through tasks. Yes, hay harvest is a task that requires you to time your work for best success, but nothing is more important than worker safety. Take your time to maintain your machinery, your stamina, and your focus.
Best wishes to all for a productive and happy summer ahead!
