8. TRADITIONAL FARMING PRECISION FARMING
Whole field approach where field is
treated as a homogeneous area
Farm field is broken into
“management zones”
Decisions are based on field averages Management decisions are based on
requirements of each zone
Inputs are applied uniformly across a
field
PF tools (e.g. GPS/GIS) are used to
control zone
Traditional Farming vs PF

9. ⮚PF adopted - USA, Europe, Canada and Australia.
⮚ Agriculturally progressive states such as Punjab, Haryana, Gujarat &
Rajasthan, 20% of agricultural lands have operational holding of 4 ha
or more. (Talwar et al., 2005).
In India :
⮚Space Application Center (ISRO), Ahmedabad has started experiment

17. ⮚All phases of
precision
agriculture require
positioning
information and it
can be provided by
the GPS.
1. Global Positioning System (GPS)
An instrument that receives satellite signals to calculate your
position (latitude, longitude and elevation).
www.remotesensing application in agriculture.com

18. ⮚ GPS provides the accurate positional information,
which is useful in locating the spatial variability with
accuracy
⮚ This is the satellite-based information received by a
mobile field instrument sensitive to the transmitting
frequency.
⮚GPS help in identifying any location in the field to
assess the spatial variability and site specific
application of inputs.

19. ⮚ GIS is the tool (Computer software) used to stores, analyzes and
displays spatial data and its corresponding attributes.
2. Geographic Information Systems (GIS)
• Attributes include: soil type, pH,
salinity levels, nutrient levels, and crop
history
• GIS is the key to extracting value from
information on variability.
• GIS can store, calculate, and model
current and historical data.
• Maps are the main visual output but can
include reports, tables and charts.

20. (GIS-the brain of precision farming)
Lina D Shinde.(2020)

21. ⮚ In Grid Sampling, the entire field is divided into equal squares (0.5-
5 ha)
⮚ Sampling soil within the grids is useful to determine the
appropriate rate of application of fertilizers.
⮚ Several samples are taken from each grid, mixed and sent to
the laboratory for analysis.
⮚ Collected composite sample represented each area
appropriately.
⮚ Fertility Map produce, provide accurate information about
soil reaction, nutrient status.
⮚ Provides a good assessment of variability.
Grid Sampling

22. A) Point Sampling B) Cell Sampling
Two methods for Grid Sampling

23. ⮚ Variable rate application (VRA) in precision agriculture is an area of
technology that focuses on the automated application of materials to a
given landscape.
⮚ The way in which the materials are applied is based on data that is
collected by sensors, maps, and GPS.
⮚ These materials include things like fertilizers, chemicals, and seeds, and
they all help optimize one’s crop production.
⮚ During the creation of nutrient requirement map for VRT, profit
maximizing fertilizer rate should be considered more rather than yield
maximizing fertilizer rate.
Variable Rate Technology (VRT):

24. Multiple sources present various economic benefits of VRA
highlighted below
1. Savings on fertilizers and chemicals.
2. Based on a study at the University of Illinois, the farmers
can save about 5 USD per acre due to a VRA technology
for nitrogen fertilization.
Potential yield increase
Environmental protection from excess fertilisation or
spraying of chemicals.

25. ⮚ Varying the
application rates of
seed, fertilizer or
pesticides to adjust
for in-field
differences
⮚ Historically,
intensive soil
sampling had
been necessary to
measure and
adjust for this
variation.

26. ⮚ Yield maps are produced by
processing data from adapted
combine harvester that is
equipped with a GPS, i.e.
integrated with a yield
recording system.
⮚ Yield mapping involves the
recording of the grain flow
through the combine harvester,
while recording the actual
location in the field at the same
time.

27. ⮚ Remote sensing has been used in soil mapping, terrain
analysis, crop stress, yield mapping and estimation of soil
organic matter, but on a scale larger than what is required for
precision agriculture.
⮚ Remote sensing at high resolution can be of great use in
precision farming because of its capacity to monitor the spatial
variability.
⮚ The role of satellite remote sensing in PF is to acquire
spatially- and temporally-distributed information to identify
and analyze crop and soil variability within fields.

30. ⮚These sensors can be used to measure soil parameters
such as N status and soil pH and crop properties as the
sensor attached tractor passes over the field.
⮚The soil sample is scooped, pressed against an
electrode, stabilization period of about 10-15 seconds
allowed, and the reading taken.
Proximate Sensors

31. ⮚In order to analyze the data collected by other
Precision Agriculture technology components and to
make it available in usable formats such as maps,
graphs, charts or reports, computer support is
essential along with specific software support.
Computer Hardware and Software

32. ⮚Recent developments are being released for commercial
use in sprinkler irrigation by controlling the irrigation
machines motion with GPS based controllers.
⮚Wireless communication and sensor technologies are
being developed to monitor soil and ambient conditions,
along with operation parameters of the irrigation machines
(i.e. flow and pressure) to achieve higher water use
efficiency
Precision irrigation systems:

33. ⮚ Auto-guidance system allows farmers to
maintain straight rows during farm operations and
to come back to the same rows the next season.
⮚ They allow more precise input application with
these systems.
Auto-guidance systems

34. ⮚ One of the latest developments is the
increase in the use of drones, for
agriculture.
⮚ Drones are remote controlled aircraft.
⮚ These have a huge potential in agriculture
in supporting evidence-based planning and
in spatial data collection.
⮚ Drones can help in …
a. the analysis of soils and drainage
b. crop health assessment and
c. In variable rate application of liquid
pesticides, fertilisers and herbicides
on small case
Drone Technology: (UAVs)

35. ⮚ What is Robot
⮚ Agricultural robots automate slow, repetitive and
dull tasks for farmers, allowing them to focus
more on improving overall production yields.
⮚ Some of the most common robots in agriculture
are used for:
1. Harvesting and picking
2. Weed control
3. Autonomous moving, pruning, seeding, spraying
and thinning
4. Sorting and packing
5. Utility platforms
Farm Automation/ Robots :

36. Following steps for a DSS:
Decision support system (management)
⮚Identify environmental and biological states and processes in the field that
can be monitored and manipulated for the betterment of crop production.
⮚Choose sensors and supporting equipment to record data on these states and
processes.
⮚Collect, store and communicate the field recorded data.
⮚Process and manipulate the data into useful information and knowledge.
⮚Present the information and knowledge in a form that can be interpreted to
make decisions.
⮚Choose an action associated with a decision to change the identified state or
process in a way that makes it more favourable to profitable crop production.

42. Case Study
Case Study

43. Case study : 1
The study was conducted in the Dharmapuri district and data on precision and non-precision farmings were
collected through the interview schedule during the year 2007.
The respondents were selected randomly from the five identified blocks in such a way that there were 35
adopters and 35 nonadopters of precision farming in each of tomato and brinjal crops, making the total
sample to be of 140 respondents.

46. Case study : 2

47. • conducted a 3-year project to investigate the agronomic efficiency of VR application
of P and K fertilizers in potato production on a 2-ha field.
• As a first step, spatial variability on the site was investigated. An intensive soil
survey of the field revealed high pedodiversity.
• The experimental field was stratified into eight soil map units, representing four soil
series and also differentiated based on soil textural class of the A horizon and slope
(Fig. 2a).
• An intensive grid sampling (15 m×15 m; n= 106) of the 0–20-cm soil layer was
performed to study the spatial variability of P and K. Soil P ranged from 8 to 274 kg
P ha−1 with a mean value of 90 kg ha−1 , and soil K ranged from 29 to 338 kg K
ha−1 with a mean value of 111 kg ha−1
• Based on the kriged maps (Fig. 2b, c), an experimental strip plot design with three
treatments and four blocks was implemented (Fig. 2d).
• The control treatment had no added fertilizer, the uniform rate application (URA)
treatment consisted of uniform application of P and K, and the VR application
(VRA) treatment consisted of variable rate of application of P and K based on the
kriged maps of P and K and local fertilization recommendations

48. In one year out of three, VRA of P and K significantly increased the total and marketable tuber yield compared with the
uniform application of P and K

49. Conclusion….
⮚ Precision Farming in many developing countries including
India has numerous opportunities for farmers to identify better
high yielding location specific crops.
⮚ Precision Farming can immensely help in reducing cost of
production and increase profits and marginal return.
⮚ Using the key elements of information, technology and
management; precision faring can be used to increase
production efficiency, improve product quality and protect
environment.
⮚ The PF would trigger a techno-green revolution in the world or
in India.
