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 Following Outdated Maps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.
