Frequently Asked Questions (FAQ)

Yes, your data is private and secure. Only you and your approved advisors (such as your CSP) can access your field information. Additionally, as a Sentinel customer you are protected by an Ag Data Use Agreement that gives you co-ownership over your data with Sentinel. Through this agreement Sentinel is legally restricted from providing data to any third party without your consent. Sentinel is permitted to use your data to improve the services delivered to you and may anonymize and aggregate your data for performance reporting purposes.

Yes, by optimizing nitrogen applications, Sentinel mitigates excessive fertilizer use, thereby minimizing environmental impact and addressing concerns like nitrate leaching into water resources.

In on-farm trials, Sentinel has improved profits by $24 per acre and increased nitrogen use efficiency by 30%. It has been instrumental in helping farmers optimize applications and improve operational efficiency. Commercial results have shown consistent profit improvements of more than $37/ac across hundreds of fields and multiple years.

The cost of Sentinel can vary depending on the tier selected and the level of service provided by each CSP. Sentinel is generally priced to provide a 3x ROI. Please reach out to a local CSP to learn more about pricing.

Sentinel offers support through its Sentry Network of Certified Service Providers (CSPs), who combine local agronomic expertise with Sentinel insights. Sentinel also offers training for onboarding and an in-app chat box for users. Additionally, Sentinel hosts webinars periodically to present new features. More information can be found on our YouTube channel: http://www.youtube.com/@sentinel-ag.

Sentinel uses satellite imagery that captures data in visible and near-infrared wavelengths. This imagery is 3m/pixel resolution, and is well-suited to sense crop nitrogen response and asses plant health. Typical imagery frequency is 3-4 quality images per week.

Yes, Sentinel is accessible via web browsers on both desktop and mobile devices, providing flexibility for in-field decision-making. A shortcut to Sentinel can be installed on your mobile device’s home screen.

Sentinel utilizes near-daily satellite imagery to mitigate the impact of cloud cover. The platform ensures consistent monitoring by selecting the clearest images available for analysis.​ However, if no imagery is available for multiple days in a row, a model-based recommendation is available, ensuring that growers never go without a recommendation.

Both tiers provide 12 months of software access. Sentinel offers 6 months of image-based insights, activatable at any time, while Sentinel Advanced provides continuous image-based insights for all 12 months. Additionally, Sentinel only offers flat-rate recommendations while Sentinel Advanced offers variable rate recommendations.

Although Sentinel was developed for use in fertigated acres, we have since expanded to service rainfed and non-fertigated irrigated acres, particularly acres that receive nitrogen applications after planting.

Currently, Sentinel is optimized for corn and cereal grains, such as wheat, oats, and barley. However, additional crops are in beta and Sentinel expects to release these capabilities soon.

Yes, Sentinel can also provide flat-rate recommendations for a field, using real-time imagery analysis. VRT technology is not required.
