LIMITATIONS OF
PRECISION FARMING
PRESENTER – SNEHA KUMARI

2. PRECISION FARMING
(Definition)
1.Precision farming is a farming management
concept that involves observing, measuring,
and responding to variability in crops. It's also
known as site-specific crop management.
2.Precision farming uses digital tools like AI,
machine learning, and IoT to optimize crop
yield and quality while minimizing costs and
resources. It also uses data collection and
remote sensing with Global Positioning
Systems (GPS) and Geographic Information
Systems (GIS).

4. PRECISION FARMING PROVIDE FARMERS
WITH A WEALTH INFORMATION

• build up a record of their farm
• improve decision-making
• foster greater traceability
• enhance marketing of farm products
• improve lease arrangements and relationship with landlords
• enhance the inherent quality of farm products (e.g. protein level in bread-flour
wheat)

5. Precision agriculture uses
technology on agricultural
equipment (e.g. tractors,
sprayers, harvesters, etc.):

6. •Geolocating a field enables the farmer to overlay
information gathered from analysis of soils and
residual nitrogen, and information on previous
crops and soil resistivity. Geolocation is done in
two ways
1.The field is delineated using an in-vehicle GPS receiver as
the farmer drives a tractor around the field.
2.The field is delineated on a basemap derived from aerial
or satellite imagery. The base images must have the right
level of resolution and geometric quality to ensure that
geolocation is sufficiently accurate.

7. VARIABLES
Intra and inter-field variability may result from a
number of factors
These include climatic conditions (hail, drought, rain,
etc.), soils (texture, depth, nitrogen levels), cropping
practices (no-till farming), weeds and disease.
Permanent indicators—chiefly soil indicators—provide
farmers with information about the main environmental
constants. Point indicators allow them to track a crop's
status, i.e., to see whether diseases are developing, if
the crop is suffering from water stress, nitrogen stress, or
lodging, whether it has been damaged by ice and so on

8. STRATEGIS
Using soil maps, farmers can pursue two strategies to adjust field inputs:
•Predictive approach: based on analysis of static indicators (soil, resistivity, field history, etc.) during
the crop cycle.
•Control approach: information from static indicators is regularly updated during the crop cycle by:
• sampling: weighing biomass, measuring leaf chlorophyll content, weighing fruit,
etc.
• remote sensing: measuring parameters like temperature (air/soil), humidity
(air/soil/leaf), wind or stem diameter is possible thanks to Wireless Sensor
Networks[22] and Internet of things (IoT)
• proxy-detection: in-vehicle sensors measure leaf status; this requires the farmer to
drive around the entire field.
• aerial or satellite remote sensing: multispectral imagery is acquired and processed
to derive maps of crop biophysical parameters, including indicators of disease.

9. ECONOMIC BENEFITS
•Increased profits
•Precision farming can increase yields and reduce pollution, which can lead to
higher profits.
•Reduced costs
•Precision farming can reduce operating costs by eliminating input overlaps and
skips.
•Reduced labor costs
•Precision farming can reduce labor costs by 20%.
•Reduced pesticides
•Precision farming can reduce the number of pesticides, which can maintain soil
health.
•Reduced environmental risks
•Precision farming can reduce greenhouse gas emissions and nutrients leaching. 2/3/20XX

10. ENVIRONMENTAL
BENEFITS
•Reducing the use of pesticides and nutrients, which can
reduce eutrophication and pollution
•Saving water and energy
•Minimizing greenhouse gas emissions, soil erosion,
water pollution, and biodiversity loss
•Increasing crop production by 4%
•Increasing fertilizer placement efficiency by 7%
•Reducing the use of herbicides and pesticides by 9%
•Reducing the use of fossil fuels by 6%
•Reducing the use of water by 4%

11. The Internet of things is the network of physical objects
outfitted with electronics that enable data collection and
aggregation.
IoT comes into play with the development of
sensors[49] and farm-management software. For
example, farmers can spectroscopically measure
nitrogen, phosphorus, and potassium in liquid manure,
which is notoriously inconsistent.
They can then scan the ground to see where cows have
already urinated and apply fertilizer to only the spots that
need it.
This cuts fertilizer use by up to 30%

12. In order to maintain agricultural development,
it will increase agricultural productivity and
stop soil degradation in cultivable land.
It will lessen the overuse of chemicals in crop
cultivation.
Precision farming will allow for effective use
of water resources.
GPS makes it simple to scan agricultural
lands. Additionally, maps of soil properties and
yield are also possible
ADVANTAGE OF PRECISION
FARMING

13. Farmers may be discouraged from using this
farming practice by high capital expenditures.
Before being used, precision agriculture
techniques still need professional advice as
they are in the early stages of development.
Before the system has collected enough data
to be completely implemented, it may take
several years.
It is a really challenging undertaking,
especially the data collecting and analysis

PRECISION FARMING

14. BENEFIT OF PRCISION FARMING IN INDIA
In India, improving and expanding the use of precision agriculture technologies
can aid in lowering production costs, raising productivity, and more effectively
utilizing natural resources.
By enhancing profitability, productivity, sustainability, crop quality,
environmental protection, on-farm quality of life, food safety, and rural economic
development, it has the potential to revolutionize modern farm management in
India.
Site-specific uses of irrigation, herbicides, and fertilizers in cotton fields, oil
palm plantations in South India, and coffee and tea gardens in Eastern India can
significantly lower production costs and chemical pollution in the environment

15. REDUCE
COST
1.Being able to accurately
decrease fertilizer, herbicide or
seed rates in areas where it will
not be economical to utilize is
one of the key benefits of
precision agriculture.
