SOURCE
Wake up your soil with SOURCE. It works with the microbes you’ve already got in your soil, and the equipment you already use, to give crops access to more nitrogen and phosphorus. Use SOURCE to replace 25 lbs of nitrogen and 25 lbs of phosphorus at half the cost.
It’s like caffeine for microbes.

-
ACTIVATES THE SOIL
First of its kind foliar-applied microbiome activator that helps you get more nitrogen and phosphorus from your soil.
-
SIMPLE AND FLEXIBLE
With a low use rate, SOURCE can be added to a tank mix alongside herbicides or fungicides.

Reduce Nitrogen Without Impacting Yield
When a field has an NUE score of 1.0 or greater, we recommend using SOURCE and reducing nitrogen to gain the best ROI. The data shown here is from nearly 50 fields across grower and third-party trials. Each site reduced N and added SOURCE, providing more than $20/ac of savings on N costs.

Reduce Phosphorus Without Impacting Yield
USE SOURCE TO UNLOCK THE PHOSPHORUS IN YOUR SOIL THAT IS GOING UNUSED.
SOURCE activates phosphorus solubilizing soil microbes, allowing growers replace 25 pounds of phosphorus while maintaining yield. The data shows the average SOURCE yield effect in small plot trials.

Increase Access to 11 Key Micronutrients
WITH SOURCE, YOU GET A LOT MORE THAN JUST NITROGEN.
Using data from 319 fields in 24 states, tissue tests across multiple seasons show that SOURCE helps improve nutrient levels, especially where crops are experiencing nutrient stress. The extra N+P provided by SOURCE increases root mass, which leads to enhanced uptake of multiple macro and micro nutrients.
The Science
Improving nutrient use efficiency through biochemistry
Plants and microbes behave symbiotically – microbes provide plants with N&P and in exchange the plant feeds the microbes.
SOURCE mimics a signal that attracts microbes to plants. More microbes means more opportunity for nutrient exchange.
Plants create exudates to feed microbes in natural systems. However, synthetic nitrogen weakens that connection and plants are not able to access the nutrients they need.
SOURCE helps restore the natural connection between plant and microbe again. In doing so plants are able to access the nutrients they need when they need it.
Microbes produce enzymes that transform phosphorus into a form that is digestible by plants.
SOURCE replicates that chemical signal, causing the microbes to increase activity and deliver more digestible phosphorus to the root mass.
