U.S. company Sound Agriculture launches Source, a foliar spray that unlocks existing nitrogen and phosphorus in the soil.
Available for the 2020 season, Source mimics natural plant-to-microbe signals that initiate atmospheric nitrogen fixation and phosphate solubilisation nutrient cycling functions.
By doing so, Source unlocks these vital nutrients and enables them to be used by the plant. This in-season boost of nutrition can lead to increased yield and improved plant health, according to Californian company Sound Agriculture.

“Growers are facing new challenges that traditional tools were not designed to address,” said Diego Angelo, chief commercial officer for Sound. “Unpredictable weather and nutrient loss are significant issues that require smart tools. Source makes it easy for growers to respond to in-season nutrient deficiencies and increase yield in a more environmentally sound way.”

Source is a foliar spray that is compatible with most tank mixtures. It offers a flexible application window from post-emergence through tassel, and can be stored at ambient temperatures.
Source was used in 130 trials across 23 states in 2019. In previous seasons, Source was shown to increase yield by an average 9.6 bushels per acre, achieving positive yield increases 88% of the time.
Source was used in 45 trials that averaged yield below 240 bushels per acre and N use below 200 lbs. per acre.
