Ground-based canopy reflectance sensing for variable-rate nitrogen corn fertilization
Nitrogen available to support corn (Zea mays L.) production can be highly variable within fields. Canopy reflectance sensing for assessing crop N health has been proposed as a technology to base side-dress variable-rate N application. Objectives of this research were to evaluate the use of active-light crop-canopy reflectance sensors for assessing corn N need, and derive the N fertilizer rate ...

Extreme Makeover: Photosynthesis Edition
Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

Are you lighting for optimum yields?
How do you achieve the highest yields with your lighting system? As we know, increasing light intensity up to a certain species-specific point, results in a corresponding increase in yield. And when light levels are not optimized for production, or the type of crop you are growing, you are going to have slower flowering, poor root development and plant structure, as well as reduced yields. There ...
