ive never heard of fertilizer with those ratings... thats a ton of nitrogen right there, the weeds would go crazy also

Yep, I use 6-12-12 on my clovers here, was going to use triple 13 this last time I fertilized, but coop didnt have any so went with the 6-12-12 again. Clovers are nitrogen fixing and make their own. Using that much nitrogen if I am not mistaken unless you get a lot of mositure, might possibly burn up your clovers and will also promote more weed growth as mentioned above.

Re: 46-0-0

Both soil samples suggested the 100 lbs per acre of 46-0-0 after it has grown 2",maybe I read it wrong and that's just for wheat/grasses.

On this plot I planted yesterday I was supposed to add 200-250 lbs an acre of 10-20-10 and I only had 100 lbs which I spread and disced in then planted.

Would it be ok to add another 100 lbs of 10-20-10 on top of the seed now?This plot is a little less than an acre.

Did you ever figure out if the 46-0-0 recomendation was for the legumes or just the grasses. Definitely makes sense for grasses, although I'm surprised no recomendation for P and K, usually they need some when first planted. confused.gif

Re: 46-0-0

no the 10-20-10 will not burn your plot.

I always top dress my plots (perennials and annuals) with 50# of 34-0-0 a couple weeks before hunting season---of course weather permitting (need rain). The extra nitrogen gives everything a little boost and make the plot "taste" a little better thus being more attracting. The nitrogen (if broadcasted right before a rain) will not harm your clover in anyway.

The main reason people don't recommend fertilizing with nitrogen for your legumes is that they are able to "produce" their own nitrogen so any extra nitrogen will just increase weed/grass competition. I strongly feel this is true in the warm season but less important in the cool season when weeds and grasses are not a problem.

Re: 46-0-0

The guy wrote this on both soil samples: top dress grass crops such as wheat,oats,ryegrass,etc using 100# 46-0-0 per acre when growth reaches 2" in heighth.

Inola sample

ph lime needed 1.9 tons ecce/a

nitrogen adequate none

phosphorous 96% sufficient 16.8lbs/acre p2o5 annually

potassium adequate none

apply 40lbs of 18-46-0 per acre

Coweta sample

ph lime needed 2.5 tons ecce/a

nitrogen adequate none

phosphorous 78% sufficient 42lbs/acre p2o5 annually

potassium 95% sufficient 18.4lbs/acre k2o annually

apply 200lbs 10-20-10 per acre

Re: 46-0-0

I hope that you guys are taking soil samples and fertilizing according to what the soil sample says.

If you aren't you are potentially throwing away money.

Also if you are going to apply some 46-0-0, which is urea, make sure you do it as close to a rainfall event, or till it in if doing it pre plant.

If you spread it and it does not get washed in soon it will volitalize into the air and it will be lost.

Also if you add nitrogen to legumes basically what will happen is the legumes will be lazy and use the fertilizer rather than have the rhizobium bacteria nodulate on them and get their nitrogen for them.

ousooner fan22, I am not sure what your soil report is saying by phophorus or potassium being a certain percent sufficient.

I have never seen a soil test reported like that, and I work with crops and soils every day for a living, and taught undergraduate soils classes while in grad school.
