Agronomic Strategies to Maximize Rotational Benefits from Alfalfa to Corn

By Jeff Coulter
 
 
Corn grown after alfalfa usually has increased yield, reduced nitrogen requirement from fertilizer or manure, and reduced pest pressure compared to when corn follows other crops. The extent and consistency of these benefits in first- and second-year corn are influenced by the effectiveness of alfalfa termination, as alfalfa can greatly complete with corn for water and nutrients.

Nitrogen management guidelines for first- and second-year corn following alfalfa are available at http://z.umn.edu/fertilizingcorn. These guidelines are based on factors such as soil texture, age of alfalfa at termination, and alfalfa termination timing.

What Is Remote Sensing In Precision Agriculture? In this informative video, we will dive into the fascinating world of remote sensing and its role in precision agriculture. Remote sensing technology allows farmers to gather critical information about their fields without the need for physical presence. By utilizing satellites, drones, and aircraft equipped with advanced sensors, farmers can monitor various aspects of their crops, from temperature and moisture levels to overall plant health.

We will explore how the data collected through remote sensing can empower farmers to make strategic decisions for their crops. With the ability to identify specific areas that require more water or nutrients, farmers can optimize resource usage, leading to healthier plants and improved yields.

Moreover, remote sensing plays a vital role in tracking crop growth over time. By comparing images taken at different growth stages, farmers can evaluate their crops’ development and adjust their management practices accordingly.
