Sized from your soil test
Does your soil actually need Advanced-Cal?
Upload your soil test and we'll read every value on it. If your soil calls for Advanced-Cal, you get the exact gallons and delivered price. If a different product would earn more first, we'll say that instead.
No test yet? Order a kit — or key your numbers in on the calculator. The read is free either way.
Pick your crop, enter acres, and drop the report. We'll tell you straight whether Advanced-Cal is where your first fertility dollar should go.

Straight answer: not Advanced-Cal first
Based on this test, Advanced-Cal isn't where we'd spend your first fertility dollar. Your soil calls for — ahead of it.
When our products don't fit your soil, we say so — the advice is free and the program is built on your numbers, not ours.
Why it's in your program
The science. The payback.
Science
Pro-Cal's bigger sibling. Same calcium correction plus chelated micronutrients (boron, manganese, iron, sulfur) and a microbial blend. One pass restores Ca chemistry, places the micros, and inoculates biology, all together.
ROI
Three passes collapsed into one: saves labor, freight, and tank-mix windows. Strongest on fields where Ca correction stacks with micro and biology deficits (the usual story on long-cropped row-crop ground).
What it is
Chelated Liquid Calcium + Micros + Microbes
Pro-Cal's bigger sibling. Adds chelated micronutrients (boron, manganese, iron, sulfur) and a microbial blend that lifts nutrient cycling and fertilizer efficiency alongside the calcium correction.
What rate do you need?
Find your soil, read your rate.
The general application rate for Advanced-Cal, by soil pH and calcium base saturation — and how many acres each container treats at that rate. The lower your pH and base saturation, the more it takes to correct. An agronomist confirms the final rate against your CEC and the rest of your test.
| Soil pH | Base saturation | Apply | 5 gal jug treats | 55 gal drum treats | 275 gal tote treats |
|---|---|---|---|---|---|
| 6.5–7.0 | 65–75% | 0.5 gal/ac | 10 ac | 110 ac | 550 ac |
| 6.0–6.4 | 59–64% | 2.0 gal/ac | 3 ac | 28 ac | 138 ac |
| 5.5–5.9 | 50–60% | 3.0 – 3.5 gal/ac | 1–2 ac | 16–18 ac | 79–92 ac |
| 5.0–5.4 | 40–50% | 3.5 – 4.5 gal/ac | 1 ac | 12–16 ac | 61–79 ac |
| 4.5–4.9 | 30–40% | 5.5 gal/ac | 1 ac | 10 ac | 50 ac |
Already at 65–75% base saturation? You're in maintenance — half a gallon holds it. Not sure where you land? Run your soil test through the calculator. Delivered pricing for every size is on the order selector above.

The research
The evidence behind Advanced-Cal, ours and everyone else's.
Every figure carries its source. Independent research shows where the agronomy holds up; our own replicated trials show it on the ground.
AgriTec trials
-
The full AgriTec wheat program yielded 99 bu/ac versus 79 on the conventional N-only control, a +25% lift on a replicated six-plot trial with identical starting soil (pH 5.4).
Agricenter International trial · Memphis, TN
-
Replicated on-farm trial partnerships across the Southeast: peanut (Auburn University), soybean (Alcorn State University), and forage (Tuskegee University).
AgriTec university trial partners
Independent research
-
Only 15–30% of applied phosphorus is recovered in the first year. Soil chemistry, not the fertilizer rate, gates how much P the crop actually sees.
FAO Bulletin 18: Syers, Johnston & Curtin 2008
-
Corn is highly zinc-responsive below ~0.5 ppm DTPA; adding zinc to a starter lifts yield ~6–7% on zinc-short soils and nothing where zinc is already adequate.
U. Minnesota & Kansas State Extension; NDSU Carrington REC (Endres 2023)
Independent findings are general to the nutrient or mechanism and describe where a response is likely, not a guarantee on your field. Match them to your soil test; an AgriTec agronomist will help.
