What soil test does hemp grain need?
Test the field before you fertilize hemp grain. The sample can match your usual lab panel. The bill should not, because grain has to fill seed.
What soil test does hemp grain need?
A current test of the field you will plant, read for a crop that has to flower and set seed. Use the panel your lab already runs, including pH. Do not apply the fiber nitrogen note or last year's corn sheet without looking. HFGA treats residual nitrogen after corn, soy, and wheat as different. rechem does not publish its own soil-test form.

What soil test does hemp fiber need?Test the field before you fertilize hemp fiber. HFGA's agronomy note puts fiber near pH 6.0 to 7.0. The nitrogen number still depends on the last crop.
Grain removes seed. A soil test that you then treat as a fiber bill, or as a corn bill, answers the wrong crop. Heartland puts hemp on farms that already soil-test for corn and soy. Keep the habit. Change the decision.

Residual is part of the test
HFGA's nitrogen note says the previous crop changes what you still need to apply. Soybeans are not corn. University of Florida IFAS publication SS689 says the public recommendation set is incomplete, and the Kentucky figures they cite are higher for grain than for fiber. Cite them as theirs. Do not staple them to your lab report and call it rechem.

FAQ
Quick answers about this part of the approach.
Can I use the fiber soil test?
You can use the same sample. You should not use the same fertilizer decision. Grain is paid for seed, not for bast.
What if soybeans were the last crop?
HFGA says a soybean field often leaves more nitrogen than a corn field. Test it. Do not guess the credit.
What pH?
HFGA's published range in the agronomy note is for fiber, around 6.0 to 7.0. Grain on the same soils still wants that test in hand. This page will not invent a second pH band.
Will the test tell me a hemp rate?
Maybe not. University of Florida IFAS says U.S. recommendations are still thin. The test still tells you what is in the field.
Where does rechem fit?
Organic chemistry on the seed and in the planting pass, after you have a seedbed and a test. It is not the fertilizer analysis.
