CONCLUSION
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.
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.
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.
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 Following Outdated Maps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
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
GPS DESIGN
IN TRACTOR GUIDANCE:
FARMER’S ADOPTING TECHNOLOGY
Computer vision will permit appropriate pesticides use & weeds and crops can be more easily differentiated
SOIL SAMPLING
GPS soil sampling provide detailed
information about soil.
Soil Sampling Methods:
Grid sampling
Directed sampling
GRID SAMPLING
• intensive sampling of entire field •Data collected for each cell •Multiple samples combined into each cell sample
DIRECTED SAMPLING
•intensive sampling of particular target areas• GPS used to locate sample points.•Areas of interest intensely sampled, others lightly sampled
SEMI-AUTOMATIC SOIL SAMPLER
ERROR & ITS CORRECTION IN GPS
Errors causes due to
following reasons.
• Due to atmosphere
• Due to multi path
DGPS SYSTEM
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.
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.
