Baling Sorghum-sudangrass Hay

Looking east across a field of sorghum-sudangrass

There's nothing really exciting about baling some sorghum-sudangrass hay, but for some reason it seems like there are a lot of visits to the blog looking at the sorghum-sudangrass stuff, so for what its worth I thought I'd write about the sorghum-sudangrass I grew this summer. 

I planted about 36 acres of sorghum-sudangrass back on June 24, but instead of grazing it after it winter-killed like I did last year, I decided to bale it this summer.  One of the main reasons for baling hay instead of grazing it this winter is that I'm planning on planting grain sorghum next spring and I don't want to take the risk of ending up with a bunch of volunteer sorghum-sudnagrass in my grain sorghum field like I had this year.  Depending on how much rain we get, the sorghum-sudangrass should easily regrow to about 18-24 inches tall in the next few weeks or so, then I'll graze it off with the cattle and plant some wheat as a cover crop (at a much lower rate than I'd normally plant).  I'm thinking about planting a simple mix of wheat and turnips to feed the worms, cattle, and deer, but I don't know if that will happen until it happens.    

This summer, I planted a photoperiod-sensitive type of sorghum-sudangrass which means it won't start heading until the days get shorter than 12.5 hours in length. Because of that trait, it is supposed to make a higher quality hay because the maturity is delayed until sometime in September, which means it produces more leaves for a longer period of time instead of producing a head and getting more stemmy.  All of that also means that the seed costs more, and at this point, I'm a little undecided about if it grew any differently than "ordinary" sorghum-sudangrass would have grown and if the extra seed cost was worth it, although I'm leaning awful hard in the direction that ordinary, cheaper sorghum-sudangrass would work just as well for the way I grow and manage it.

From what I've seen,  photoperiod-sensitive sorghum-sudangrass would be better suited to a situation where it was being planted in late-April and was going to be cut for hay multiple times over the summer.   If you're going to double crop it after wheat or are planning to graze it in the summer, the ordinary, hopefully cheaper varieties of sorghum-sudangrass might be the better choice.

It's almost hard to see where you're driving in a field of 5-6 foot tall grass

The cropland around here is all terraced, so I usually try to break the fields up when I cut them for hay so that I'm not driving up and down the terraces on the ends as much (which probably doesn't make any sense at all to someone that doesn't know what I'm talking about).  In other words, instead of cutting one big square, I like to divide it up into two or more long rectangles.  All of that means that I have to dive into the middle of the field on that first pass across the field and almost drive blind while trying to follow a terrace. This year, I only had to deal with grass about 5-6 ft. tall, but I've cut some that was 8 ft. tall where I almost ran through the fence on the end when I didn't turn soon enough, it felt like driving in thick fog and almost going off of a cliff. So, if you plant some sorghum-sudangrass, don't wait too long to cut it, and I wouldn't plant it if you have a bunch of hidden obstacles in your field.

Besides that, baling sorghum-sudangrass is about the same as any other grass hay except that it's a little trickier getting it dry enough to bale while also trying to make sure it doesn't get too dry.  If anyone is thinking about baling sorghum-sudangrass, it's pretty important to cut it with something like a disc mower conditioner which crimps the stem so that it will dry down quick enough.  Even though I use a disc mower, most of the time it'll take at least an extra day or so for it to be dry enough to bale. 

Every time I've baled sorghum-sudangrass, the bales seem to come out much heavier and tighter than my other grass hay bales.  I've never weighed any bales, but I'd guess that my sorghum-sudangrass bales are at least 10-20% heavier, so there's even more hay out there than you'd think there was at first glance.

My bales also always seem to have a "shaggy" look to them when they are first baled, it always makes me get off of the tractor to double-check those first bales since it looks like the bales aren't being tied right or are loose, but I think it's just the nature of the grass and after the bales have set for a while they start to lose that "shaggy" look.  A net-wrapped bale wouldn't have that temporary shagginess, but since my baler gives me twine-wrapped bales, the shagginess doesn't bother me at all (besides that, I'm not a big fan of net-wrapped bales).  

That's about all I know about sorghum-sudangrass hay.  It grows quick, needs a little nitrogen but not too much, it can sometimes be difficult to get dry, it makes heavy bales, and my cattle seem to attack any bales of it that I feed them (there's almost no waste and they practically lick the ground clean to get every last bit of hay).
