Phase II

Phase II 4-0-0 is a fast-release nitrogen fertilizer designed to maximize nitrogen availability and enhance plant nutrient uptake. This liquid nitrogen fertilizer helps convert nitrate nitrogen into usable seed-producing nitrogen, supporting strong root development and healthier, more productive crops. Ideal for use in row crops, small grains, hay, pastures, vegetables, and fruit crops, Phase II 4-0-0 is the best nitrogen fertilizer for farmers seeking both efficiency and sustainability. Phase II 4-0-0 is also offered in an organic version. For more information, please contact your supplier.

Available in 250 gal totes and bulk truckloads

Boost Soil Health and Root Development

Phase II 4-0-0 actively remediates and loosens soil, improving air supply and creating an optimal habitat for soil biology. Its micronized particles contain free-floating electrons that interact with soil atoms, relaxing the soil structure for easier root penetration. By promoting healthy root development, this nitrogen-based fertilizer enables plants to efficiently access essential nutrients and water, thereby increasing overall crop vigor.

Enhance Nitrogen Efficiency

When mixed 1:1 with 32% Nitrogen, Phase II 4-0-0 stabilizes nitrogen in the soil profile, keeping it available longer around the roots. This improves nitrogen uptake and reduces losses from leaching or volatilization. It can also be combined with NPK fertilizers for pop-up applications directly under the plant, delivering targeted nutrition where it is needed most.

Flexible Application Methods

Phase II 4-0-0 is compatible with a variety of application techniques:

  • Sprayers and aerial applications for foliar or soil delivery
  • In-furrow and 2×2 pop-up applications, either alone or mixed with compatible fertilizers
    (jar test recommended)
  • Pivot irrigation systems and drip tape applications, with proper flushing to protect equipment

Its extended tank life after mixing ensures efficient application without compromising nutrient quality.

Supports Soil Biology and Nutrient Cycling

This nitrogen-based fertilizer buffers salts in conventional fertilizers, encouraging soil organisms to break down nutrients faster into plant-available forms. By promoting a healthy soil habitat, Phase II 4-0-0 enhances nutrient cycling and supports long-term soil fertility, making it a valuable tool for sustainable crop management.

Frequently Asked Questions

Phase II 4-0-0 stabilizes nitrogen in the soil, reducing losses from leaching and volatilization. This ensures plants can access more of the applied nitrogen, making it a fast-release nitrogen fertilizer that maximizes nutrient efficiency.

The response is typically visible within days as nitrogen becomes quickly available for uptake, thereby improving growth and vigor.

By supporting soil organisms and increasing nitrogen availability, Phase II accelerates the decomposition of crop residues, returning nutrients to the soil for the next planting season. This adds long-term value to your nutrient management program.

Unlike standard liquid nitrogen fertilizers, Phase II 4-0-0 provides micronized particles with free-floating electrons that relax soil structure, improve root penetration, and increase nitrogen efficiency, making it a superior nitrogen-based fertilizer for commercial crops.
