No problems should be anticipated in direct feeding or ensiling. There will be some reduction of nitrate between the time of cutting and feeding. Overnight storage on wagons is not recommended because nitrite could build up. Chop and feed as needed. Dried fodders and hays.
Test stems and stalks.
If dark blue-black color rapidly develops, check the leaves. If leaves are also very positive, make a quantitative analysis before feeding the forage or feed it cautiously. Test stems of plants. If stems test positive, then test leaves. If both are positive, excessive nitrates are present and quantitative analysis is needed along with cautious feeding.
