Row Crop Agriculture

Maximizing Yield Across Every Acre

Corn, paddy rice, and high-value vegetables need a fertilizer that performs at field scale — one application, reliable release across variable soil temperatures, and a nutrient curve aligned to the crop's agronomic growth window.

Row Crop Challenges — and How HI-COTE Solves Them

Grower Challenges
  • Multiple fertilizer applications increase fuel, labor, and equipment costs per acre
  • Nitrogen volatilization and leaching reduce fertilizer use efficiency (FUE)
  • Inconsistent urea release in flooded paddy or high-rainfall conditions
  • Environmental compliance pressure on nitrate leaching into waterways
  • Price sensitivity in commodity crop economics demands proven ROI
HI-COTE Advantage
  • Sigmoid release — suppresses early N loss, peaks during rapid vegetative growth
  • Smart Fall Application (SFA) enables pre-season incorporation for corn
  • 25% coated urea in HI-COTE Paddy extends N through the flooded period
  • Reduces greenhouse gas emissions and groundwater nitrogen loading
  • Bulk packaging (1MT FIBC) for large-acreage commercial operations
Validated through field trials: Nousbo has conducted multi-season row crop trials with the University of Illinois Urbana-Champaign (UIUC) and commercial farm partners in Mexico, Brazil, and Southeast Asia. HI-COTE Corn's sigmoid release profile has demonstrated nitrogen delivery aligned with corn's V6–VT growth window — reducing over-application while maintaining or improving yield.
Release Technology

How Sigmoid Release Works in Row Crop Systems

Unlike linear-release CRF products, HI-COTE's sigmoid mechanism matches nitrogen delivery to the actual growth stages of agronomic crops.

01
Early Season: Minimal Release
Suppressed early-stage N output prevents seedling burn and salt injury before root establishment. The polymer shell restricts diffusion until soil temperature rises.
VE – V4 Stage
02
Peak Growth: Maximum Output
As soil temperature rises during rapid crop development, the polymer membrane accelerates nutrient diffusion — delivering peak nitrogen when the crop needs it most.
V6 – VT Stage
03
Grain Fill: Tapering Release
Release tapers as the crop shifts to reproductive growth — minimizing residual nitrate and lowering environmental impact post-harvest.
R1 – R6 Stage

HI-COTE Products for Row Crop Agriculture

Each product is formulated for a specific agronomic context — from corn sigmoid timing to paddy flood tolerance to vegetable dibbling compatibility.

HI-COTE
Corn (UREA-CORN)
Coated Urea — Sigmoid 60-Day Release
Corn / MaizeSmart Fall Application

Engineered to simulate corn's natural nitrogen demand curve. The sigmoid release suppresses early-season N loss and delivers a peak burst aligned with the V6–VT growth window. Supports Smart Fall Application (SFA) for pre-season incorporation.
