Field Trials 1

Reduce nitrogen without impacting yield

USE SOURCE TO REDUCE NITROGEN WHILE MAINTAINING YIELD

SOURCE effectively tackles nitrogen deficiencies in plant tissues, boosting nitrogen content by over 15% in environments without sufficient N. Thanks to the microbes activated by SOURCE, crops consistently receive the necessary nitrogen all season long.

Chart phosphorus reduction 042623

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. 

Chart nutrient increase

Increase access to 11 key micronutrients

WITH SOURCE, YOU GETLOT 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.

So much to gain, nothing to lose

SOURCE works, and we stand by it. That’s why we lead the pack with the industry’s strongest guarantees. You’ll make your money back, or we’ll pay you back.

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.
