Fertilizers represent one of the highest input costs for farming operations and

one of the most difficult aspects to manage. If applied in appropriate amounts,

it can increase yield. But if applied in excess, in addition to wasting money, it

can lead to leaching and contamination of nearby streams and lakes.

Applying the right amount requires knowledge and information. Multispectral

sensors not only allow for easy identification of areas low in nutrients but also

help monitor the effects of these applications throughout the season and

determine if, when, and where a new application is needed.
