LSU Ag test kits that are sold at Clegg's

Is this an "at home" test kit? If so I didn't know LSU Ag sold such a thing. I would just send a sample off to the lab. I would never not recommend doing that. Takes all the guess work out.

That’s gotta be what he’s talking about.

Unless something is new, Cleggs or anyone else doesn’t sell LSU AgCenter soil test kits. They have the postage pre-paid soil test boxes - they give you the boxes - that contain instructions with 3 bags you can use to mail soil samples, with payment instructions, to have your soil analyzed. No more than 3 samples per box.

The AgCenter doesn’t analyze soil for nitrogen but they will provide you a recommended nitrogen rate for your lawn grass when you get your soil test results back

For St Aug, that will be 3 lbs of N per 1000 sq year, divided among 3 applications of 1 lb of N per 1000 sq ft, in April, June and August, the August application being optional. That would be 4 lbs of the Fertilome 24-0-4 per 1000 sq ft per application.

If your soil test results show a deficiency in P or K they will provide recommendation on how much of P and K to use to correct the deficiency. If soil pH requires adjustment the results will provide a recommendation on how much Ag lime to apply to raise the pH or how much elemental sulfur to apply to lower the pH.
