Can anyone interpret and make recommendations for this soil test. metric.
ph 6.5
phosphorus 167 mg.l
potassium 1.01 me/100g
calcium 22.2 me/100g
magnesium 3.70 me/100g
sodium .16 me/100g
CEC 29 me/100g
nitrogen 263 kg/ha
organic m 11.1%

Available nitrogen and phosphorus seem high. Thanks

after running some conversions I came up with the folowing in PPM

Calcium 4440
Magnesium 444
Potassium 393.9
Nitrogen 234.6
and Phosphorus Mg/L is pretty much same aas PPM so it is 167 ppm

that being said your base saturation %'s are roughly

Calcium 81.9
Magnesium 13.5
Potassium 3.7

you could try to get the Potassium up a bit and mag a lil more too

20# of magnesium oxide per 1000 sq ft will raise the mag to around 18.2% base sat, and put your ph at about 6.8-6.9 which is fine

50# of 0-0-50 per 1000 sq ft will raise you potassium to around 7% base sat.

If you add these 2 things your calcium base sat% will end up around 74%


with a high phos you may want to think about a micronutrient supplement, since you didnt get them tested its hard to know if you need them or not, but high phos can mess with micronitrient availability.

hope this helps.

Thanks Bry. Is that 20kg and 50kg?
Yes was thinking of adding some boron and copper

20 pounds and 50 pounds.

adding boron and copper blindly can have dire consequences. using a chelated micronutrient blend is probably a better way to go and spoon fed the plant through the season.
