Spread Lime Pellets & Potash on the Garden

Gardening

1/4/2024 – Applied ten 40-lb. bags of Austinville Pelletized Dolomitic LawnLime:

From their Product Analysis sheet – “This product requires 1844 lbs. to equal one ton of standard liming material (with CCE of 90%).”

For our 0.2 acre garden (not including turn rows) with the soil report recommending one ton of standard lime per acre, we need to apply 0.2 x 1844 = 368 lbs = 9.22 40# bags.

The Plan for lime based on our spreader’s performance here:

  • Run in 4M that travels at 2.23 MPH which is almost half of the application for the course-grain 5 MPH line. Therefore, at half speed should spread twice the amount or 992#/ac at position 5. [The 5 MPH speed is for 2H not 1H as 1H is 3.7 MPH. All calculations and assumptions here are likely wrong]
  • 1844 lbs./ac is close to twice 992 lbs./ac. So set at position 5 and go over the 0.2 ac twice.
  • We need to apply 0.2 x 1844 = 368 lbs so buy 9.22 (say 10) 40# bags.

The plan for the potash was:

  • Soil lab recommended 120 lbs/ac which would be 0.2×120=24 lbs of pure potash.
  • Of 0-0-60 need to spread 24/0.6=40 lbs.
  • Buy 50 lbs and spread it with spreader on 2 and went north-south then diagonally.

Results:

The lime spreader rate was close enough based on cross spreading plus finishing off what was left by going diagonally.

The potash application also seemed to be ok…or close enough.


A 1.44″ rain on 1/5/24 caused all the pellets to disappear; i.e. melt into the soil. The pink potash pellets were also not visible.
