More Broom Sedge this year

Postby herofan » Tue Sep 12, 2017 9:27 pm

We reseeded hay fields in 2013, have fertilized once every spring since, and applied lime in 2015. I actually saw improvement each year; hay quality looked much better and production increased each year. This fall, however, broom sage is running wild. Any ideas as to why this suddenly happened?

I have always heard that lime would get rid of it, but if you limed in 2015, that is much more recent than we have limed and we haven't had it for a while.

Doing soil tests will tell you why, otherwise everyone is guessing.

Yep. Probably needs more lime but a soil test would tell for sure.

Any of the above, or it can also have to do with moisture at the right time. We were droughty for about a month and half when the broom sedge is growing most. The other grasses were drying up so there wasn;t any competition.

We have had a rainy year, and it is continuing. I just happened to notice my neighbor's hayfield on the way home today, and it is the same way. I don't recall seeing broom sedge in his fields in previous years, but he has it now.

If I understand correctly, the effects of lime are supposed to last a few years, and it takes a few months after application for it to start working. Isn't that correct? It's difficult for me to see how spreading a dust can change things so much.

Lime can only help if it's enough to adjust the pH to the proper range. And without a test there's no way to know.

My broom sedge was a bumper crop this year. Head high in many places. I had no idea it could get that tall. Bought a weed wiper to use on it, and never got time. Wish I could have tried it.

Since you are KY too, I wonder if weather played a large role?

It may be thicker than normal due to weather, but I'm convinced it's a product of low PH. Phosphorus levels figure in to it, but phosphorus can't be absorbed at acid levels.

I don;t subscribe fully to the ph and phosphorus theory. The only field that has much of it has a ph of 6.5 and the phosphorus level is classified as high. That field is always the driest on the farm, i.e. ridge top so the wind really dries it out.

I am no expert on it, but would think that yes the effects would not be seen immediately. When we have any pasture renovations done we always get a soil sample, and it will recommend the amounts to put per acre, and usually that amounts to several truck loads when dealing with lime.

Lime takes time to start working and it takes several years depending on the soil to work completely. We test every other year and watch the ph gradually increase. When it stops going up if the ph is the range we want we leave it alone. If it hasn;t reached the level desired we will lime again.
