Precision Spray Technology

Liquid Fertilizer Application

Our StreamJet® nozzle technology ensures nutrients reach the soil where they are needed, while minimizing crop damage and nutrient losses.

By combining correct timing with the right nozzle technology, growers can unlock the full value of liquid fertilizers and build stronger, more resilient crops.

LIKE RAINFALL, BUT ENGINEERED.

StreamJet spray tips on boom sprayer

Unlike crop protection products, liquid fertilizers should primarily reach the soil surface and root zone, not remain on plant leaves. Incorrect application, especially with fine spray droplets, can lead to:

  • Increased risk of leaf burn
  • Uneven fertilizer distribution
  • Higher nitrogen losses
  • Greater susceptibility to spray drift

To overcome these challenges, multi-stream (StreamJet) nozzles are the preferred solution. Instead of atomizing liquid into fine droplets, they deliver fertilizer in targeted streams, improving placement and efficiency. Additionally, the VR (Variable Rate) technology enables consistent application across different speeds without changing pressure, making it ideal for precision farming systems.

Liquid Fertilizer Nozzles

SJ3-VR-X1.0

SJ3-VR StreamJet®

The SJ3-VR tip produces three identical fluid streams for excellent distribution quality in directed applications.

SJ7A-VR-X1.0

SJ7A-VR StreamJet®

The SJ7A-VR tip produces seven identical fluid streams for excellent distribution quality in directed applications.

  • Multiple streams deliver fertilizer directly toward the soil, reducing leaf exposure and preventing plant damage
  • Uniform nutrient distribution across field
  • Less sensitivity to boom height and movement ensures reliable application, even on uneven terrain
  • Better placement reduces losses and increases the amount of nitrogen available to the crop
  • VR technology supports variable-rate fertilization, section control, and modern spray system

Best Practices

Liquid Density Conversion

When selecting a specific capacity tip for liquid fertilizer application, always correct for liquid density. Application charts shown in this catalog are based on spraying water. Many fertilizer solutions are denser than water, which will affect the application rate. Please see page 185 in the catalog for a list of density conversion factors.

EXAMPLE

Desired application rate is 20 GPA of 28% Nitrogen. Determine the correct nozzle size as follows:

GPA (liquid other than water) x Conversion Factor = GPA*

20 GPA (28%) x 1.13 = 22.6 GPA (water)

The applicator should choose a tip size that will supply 22.6 GPA of water at the desired pressure.

Maintain Proper Boom Height

Although stream nozzles are less sensitive, correct boom setup ensures optimal distribution. For best spray distribution maintain a 1:1 ratio of tip height to tip spacing.

 Apply Nitrogen at the Right Time

Early and timely application supports tiller retention, canopy development, and root growth, especially in spring when crops demand rapid nutrition.

Avoid Stress Conditions

Reduce application during high temperatures or strong sunlight to minimize the risk of leaf burn.

 Match Nozzle to Application Goal

  • Use SJ7 VR for wider coverage and maximum distribution
  • Use SJ3 VR for more targeted, controlled placement
