Is smoke stunting pasture growth?

A:

The smoke is decreasing the amount of light which has also reduced the temperature each day by a couple of degrees compared to what it would have been without smoke. This run of hot weather and smoke since the end of June is almost unprecedented. In my 28 years here, I cannot think of a worse summer! Alfalfa and other legumes love this weather as long as you are irrigating properly, our cool season grass species on the other hand do not like this hot weather. The cumulative effect of the heat over two months has certainly upped the evapotranspiration of the plants, so more irrigation water was needed to keep plants growing. If a person is grazing tight to the ground, this would also increase surface soil temperature and increase evaporation as well as hold the soil biological life in check as well (near surface).
