Reading a food plot soil sample

I’ve never had a soil sample done before. I need some help reading it and putting it to use.
My pH is 7.9
O.M. %- 5.4
P ppm- 12
K ppm- 75

Phosphorus is at the high end of low
Potassium is at the high end of very low
Rotation pH is at the high end of very high

I will he planting brassicas in this plot. Here is what it says for nutrient needs:
N- 100 lbs/A
P205- 55 lbs/A
K20- 175 lbs/ A

What furtilizers or supplements do I need to fullfill the nutrients needed? I was going to plant clover in the spring and then FF big n beasty in July. Thanks for any help.

Hmmm. Very interesting.

Your soil is actually moderately alkaline. I’m always trying to bring the PH up, not down, we have acidic soil up north so I’m always adding lime.

The question is how alkaline is too alkaline for clover? You can bring soil the PH down with aluminum sulfite, but first I’d want to know if it’s really necessary for clover at this level and that’s something I can’t answer. I’d suggest the QDMA forum or hopefully Stricker can weigh in.

Your P and K levels are low and this might be more a money question than a “what is ideal” question. This could get a little spendy to say the least. How big is your intended plot/plots?

Probably the cheapest way is to go to your elevator and get a fertilizer blend done just for you, but the economics might dictate how far you go with this depending on your plot size. Take your info in and get a quote.

Just to give you an idea, my little 1/4 acre test plot needed 200 pounds of lime just as a starter. Well see how much that raised the PH by next spring. Then 50 pounds of 10-20-20. So total cost was over $100 for that little test plot. Add in seed costs and I had almost $150 in that plot, or $600 per acre. I was using bagged fertilizer, so costs could be cut there, but only so far.

Unfortunately I can’t help much either. One thing I need to work on is learning how to read and understand soil samples. I have mine done then take it to the elevator and they mix my fertilizer. And like Grouse I have only dealt with low PH never high. Take Grouse’s advise and go to the the QDM forum. They really know there stuff and will be very helpful. That is where I get most of my advice.

OK, more info found last night. I was looking at some seed guides I had and here’s what I found for white clover:

Soils: White clover is adapted to soils with fine to medium texture that are well to poorly drained. It tolerates acid to moderately alkaline conditions (pH of 4.5-8.2), but is not tolerant of saline conditions (<6 mmhos/cm). White clover requires moderate fertility and tolerates flooding (10-20 days).

So you’re at the outer range of alkalinity, but not out of bounds.

To me, the ideal situation would be to look for some free acid amendments rather than going the high-cost route of additives.

Know anyone who has a pine tree plantation or a Christmas tree farm where you could rake up about a ton of pine needles? These are high in acid and if you could add them and till them in, would be an excellent way to reduce Ph at very low cost.
