Calcium foundation
Pro-Cal lifts pH and Ca base sat. Cotton sets earlier on balanced soils.
AgriTec System · Specialty
Cotton.
Earlier set. Heavier bolls. Cleaner pick.
Cotton responds dramatically to calcium correction and boron. Most cotton ground in the South sits below 6.0 pH with Ca base saturation under 60%, and boron under 0.5 ppm cuts boll set before harvest. Our cotton program addresses the foundation first, then drives boll fill with foliar B.

03 / The trial data
We can defend every line.
Randomized complete block, 3 programs × 4 reps, DP 1646 B2XF. Raising split-applied Nitro-Maxx+ from 15 to 25 gal/ac added 81 lb of lint over the identical standard-rate program, and the fiber held its grade. Full report on the Research page.

02 / The growth plan
From emergence to harvest: one plan, stage by stage.
The whole cotton season up top, then the general program below. Every pass is shown at the exact stage it targets, so the picture and the plan line up.
Read this first
This is a general roadmap, not an exact prescription for your farm. No two fields, soil tests, planting dates, or seasons line up the same way, so your stages, rates, and timing will differ. Treat the timeline below as the shape of the program; we size the exact stack and pin every pass to your soil test and your acres.
The plan, pass by pass, pinned to the stage it works
Each pass has a window. Hit it and it pays; miss it and the dollar's mostly spent. Tap a pass to see what it returns.

Pre-plant Pre-plantPro-Cal
3–5 gal/ac
pH + Ca foundation.
What this pass returns
The highest-return pass on Southern cotton ground. Most of it sits below 6.0 pH with calcium base under 60%. Fix that and cotton sets earlier on balanced soil, so the whole crop finishes ahead of a late, stressed one. Everything downstream rides on this foundation.
-
Planting · Squaring At planting3-18-18+
5 gal/ac
Orthophosphate P-K for early root + square set.
What this pass returns
Early root and square set decide the boll count you'll eventually pick. Available P-K in the root zone from day one is a small pass that quietly raises the season's ceiling before the plant ever blooms.
-
Pre-bloom Pre-bloomNitro-Maxx+
6 gal/ac
Sustained N for the long demand curve.
What this pass returns
Slow-release N feeds cotton's long demand curve without over-pushing rank vegetative growth. You get fruit, not just foliage, and far less N lost to leaching on sandy Southern ground.
-
Bloom · Boll set Bloom · foliarBoroLift
1 gal/ac
Defends square retention and boll set.
What this pass returns
The pass that pays the loudest. Boron under 0.5 ppm cuts boll set before you ever see it. A gallon of foliar B at flowering defends square retention and the bolls that become your check. In AgriCenter cotton work the full program ran ~350 lb lint/ac over the control.
-
Cut-out Cut-out · foliarYieldMaker
1 qt/ac
Drives finish: kelp + micronutrient trigger.
What this pass returns
Finishing pays at the gin. Kelp and micronutrients through cut-out drive the last increment of fill and fiber quality, often the difference between an average crop and a premium grade.
What's driving the response
Boron for boll set
Boron defends square retention and boll set. BoroLift at flowering is critical.
Slow-release N
Nitro-Maxx+ matches cotton's long demand curve without overpushing vegetative growth.
Foliar finish
YieldMaker keeps the plant healthy through bloom and cut-out.
