Precision Agriculture

- Overview

Precision Ag, or precision agriculture, is a farming management method that uses GPS, sensors, and data to monitor and respond to within-field variability. 

This approach uses technology to optimize crop and livestock production by applying inputs like water, fertilizer, and seed precisely where and when they are needed, leading to increased efficiency, higher yields, and reduced environmental impact.  

1. How it works:

• Data collection: Sensors, GPS, yield monitors, and drones collect real-time data on soil conditions, crop health, and field topography.
• Data analysis: Farmers and their systems analyze this data to identify variations within a field and make informed decisions.
• Precision application: Based on the analysis, machinery can adjust application rates for fertilizers, pesticides, and seeds, or use automated steering to follow the most accurate paths.

2. Key technologies:

• GPS/GNSS: Provides precise location data for guiding equipment and mapping fields.
• Yield monitoring: Records the yield of crops from specific areas to help identify high- and low-performing zones.
• Variable rate application: Adjusts the amount of an input being applied based on the specific needs of each part of a field.
• Equipment guidance and autosteer: Automates steering to follow the most precise paths, reducing overlap and skips.
• Remote sensing: Uses data from satellites or other sources to monitor fields from a distance.
• In-field sensors: Monitor soil moisture, nutrient levels, and other conditions directly in the field.

3. Benefits:

• Increased efficiency: Optimizes the use of resources like water, fuel, and fertilizer by applying them only where and when they are needed.
• Higher yields: By tailoring practices to the specific needs of the soil and crops, farmers can improve overall production.
• Sustainability: Reduces waste and minimizes the environmental impact of farming.
• Better record keeping and planning: Data management systems help farmers track performance and make strategic decisions for future seasons.
