In-season Nitrogen Real-Time VRA

Not all crops in the same field have the same nutrient requirements due to field variabilities such as soil properties, sunlight exposure, water accessibility etc. N-VRA is the process of applying different rates of Nitrogen to meet those needs while fertilizing crops in a field.

Unlike traditional fixed rate or ‘blanket coverage’ applications, N-VRA uses less fertilizer, reduces environmental impacts, and promotes crop uniformity. For it to be ‘real-time’, the data collected to determine fertilizer requirements must be immediately actionable and used while the VRA process is actually being undertaken. 

Augmenta N-VRA applies a recommended dose/rate of fertilizer in an intelligent way so as to minimize waste and maximize efficiency. Being camera-based, the Augmenta System is unique in that it uses computer vision techniques and dynamic algorithms to understand the productivity potential of different areas within a given field.  Using vegetative indices, Augmenta creates an on-the-fly prescription map and controls the spreader or sprayer to apply the appropriate amount of fertilizer all in one pass.

The Augmenta System is an unobtrusive plug n’ play retrofit system that is mounted on the cabin roof of any ordinary tractor or self-propelled spreader or sprayer. It uses ISOBUS or other OEM specific protocols to control VRA machinery and utilizes a built-in GPS to determine location. A 3G/4G cellular network connection allows cloud connectivity. The system also includes an integrated wireless Augmenta Tablet for in-cabin operator control and the Augmenta Web Portal for operational tracking and analytics, financial reports, record keeping etc. 

While in operation, the Augmenta System is not only able to recognize the productivity potential of different field areas, but its cameras can also detect anomalies such as rocky or waterlogged regions. Unlike active sensors detecting chlorophyll reflectance which would wastefully apply more fertilizer in such areas, the Augmenta System reduces the amount accordingly. Furthermore, it auto-calibrates to compensate for changing light conditions during the day.

The Augmenta System can be used on all major crop types such as wheat, canola, and cotton. Moreover, it is multi-functional and future-proof using over-the-air software updates instead of hardware updates to unlock new features as they are developed. Aside from N-VRA, it currently offers PGR and Harvest Aid Defoliant VRA operations. New services are constantly being developed, including Green on Brown selective spot spraying.

Augmenta case studies

Augmenta Case Study in Australia

The Augmenta System is designed to optimize inputs and reduce waste, thereby promoting sustainability. It is also capable of increasing uniformity, especially when field and crop conditions vary greatly. Because of its ability to both reduce input costs and improve total harvest sales, it allows farmers to enjoy significantly better financial returns.
