I have heard that in times of drought Johnson grass retains enough nitrogen to poison cattle. If this is true does it lose the nitrogen if it is cut for hay?
Thanks in advance!

Prussic acid yes. Nitrates no.

Thanks MikeC, Maybe I should have asked the question another way. Hay is very scarce in these parts, I have the oppurtunity to cut 30 acres that hasnt been cut all year, It isnt the best field by no means but it is better than nothing, it has alot of mature Johnson grass, I was really just wondering if I should be concerned about the johnson Grass?
Thanks again!

We cut Johnson grass for hay. We have never had it tested but I guess you could if your concerned.

Is that because they applied nitrogen to their fields for a quick burst?
I'm not really sure. We have JG 7' tall that I'm afraid to cut until after we get some rain.IF it ever rains.No matter how short Hay supplies are here, I'd sure hate to put it up, and get someone's stock sick/die. The Katydids were out in July, so that means an early frost.May just end up letting it lay.Wewild":1e1eoslr said:Crowderfarms":1e1eoslr said:The state has warned folks here that Johnson Grass does indeed contain Nitrates, due to the dought.Prussic acid is usually found after a freeze.

From what I just read I would say it is mainly the drought causing the high nitrate levels. Here is a good link on nitrates.
