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.

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.

  1. Cotton at Pre-plant
    Pre-plant Pre-plant

    Pro-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.

  2. Cotton at Planting · Squaring
    Planting · Squaring At planting

    3-18-18+

    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.

  3. Cotton at Pre-bloom
    Pre-bloom Pre-bloom

    Nitro-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.

  4. Cotton at Bloom · Boll set
    Bloom · Boll set Bloom · foliar

    BoroLift

    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.

  5. Cotton at Cut-out
    Cut-out Cut-out · foliar

    YieldMaker

    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

Calcium foundation

Pro-Cal lifts pH and Ca base sat. Cotton sets earlier on balanced soils.

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.
