3. INTRODUCTION:
PRECISION AGRICULTURE:
Precision agriculture (PA) can be defined as a set of
technologies that have helped proper agriculture into
the computerized information-based world, and is
designed to help farmers get greater control over the
management of farm operations.

4. WHAT IS GPS
 A position information system enables the
user to determine absolute or relative
location of a feature on or above the earth’s
surface.

5. PRECISION FARMING BEFORE:
They only record the proper information on
computer nothing more.
Apply of Fertilizer, pesticides, seed through new
machines but not in proper manner.
All field may not be covered properly.

6. A BRAVE NEW WORLD
1. Yesterday’s Farmers
1. Plough Fields With Mules
2. Following Outdated Maps
3. Work Sun-up to Sun-down
2. Today’s Farmers
1. Flip on Autopilot and Take in the Scenery
2. Have Real-time Maps on an LCD Screen
3. Work 24 Hours a Day if need be

7. GPS IN PRECISION AGRICULTURE:
Constellation of satellites
Developed by Department of Defense
Used 24 hrs./day anywhere on Earth
24 satellites
12,000 miles above Earth
Orbit twice daily

8. GPS DESIGN

9. IN TRACTOR GUIDANCE:

10. FARMER’S ADOPTING TECHNOLOGY

11. Computer vision will permit appropriate pesticides use & weeds
and crops can be more easily differentiated

12. SOIL SAMPLING
GPS soil sampling provide detailed
information about soil.
Soil Sampling Methods:
Grid sampling
Directed sampling

13. GRID SAMPLING
• intensive sampling
of entire field
•Data collected for
each cell
•Multiple samples
combined into each
cell sample

14. DIRECTED SAMPLING
•intensive sampling of
particular target areas
• GPS used to locate
sample points.
•Areas of interest
intensely sampled, others
lightly sampled

15. SEMI-AUTOMATIC SOIL SAMPLER

16. ERROR & ITS CORRECTION IN GPS
Errors causes due to
following reasons.
• Due to atmosphere
• Due to multi path
DGPS SYSTEM

17. ADVANTAGES
Saving time
Reduce fertilizer costs
Reduce chemical application costs
Reduce pollution through poor use of chemicals.
Provide better farm records essential for sale and
succession
GPS allows farmers to work during low visibility
field conditions such as rain, dust, fog, and darkness.

18. CONCLUSION
It is a novel method which guides farmer for better
agriculture and farming.
It provide better information for management
decisions.
It is the present and future guide lines for farmer.
