The document discusses the use of geospatial technology (GST) in agriculture for improving fertilizer recommendations, which includes tools such as GIS, GPS, and remote sensing. GST enhances crop yield, resource management, and environmental sustainability by providing data for optimized fertilizer application. The report outlines objectives for creating variable rate maps and emphasizes the importance of accurate soil sampling and yield goals for effective fertilizer management.

2. GEOSPATIAL TECHNOLOGY
 Geospatial technology (GST) refers to geographical information
systems (GIS), Global positioning system (GPS), and remote
sensing (RS). All emerging technology that assist the user in
the collection, analysis, and interpretation of special data.
 Geospatial technology is the term used to describe the range
modern tools contributing to the geographic mapping and
analysis of the Earth and human societies.
 It deals with the relationship and condition of manmade and
natural objects within space, be in on Earth or beyond the
Earth.

3. Geospatial technology in India
 The geospatial technology is aggressively helping in
various sector in India. The key to its usage lies in data
acquisition and visualization. The report focus on various
sector like infrastructure, urban development, agriculture,
electricity, disaster management, water, environment,
forestry and climate change.
 The GDP in India is expected to approach $9-10 trillion by
2025 and the Indian economy would be characteriserd by
its transformation to being highly industrial and
technology advanced.

4. Role of geospatial technology in agriculture
 Geospatial technology play an influential role in agriculture
sector by increasing yield, managing of resources, prediction
of outcomes.
 Geospatial technology is used mostly for surveying and
mapping of plantation crop. Mapping of rice is the major
activity in countries like Malaysia and Indonesia.
 Australia is among the major user of technologies, whereas
technologies like remote sensing, GIS are most widely used for
mapping of crop like sugarcane and oil palms.

10. Fertilizer recommendation using geospatial technology
 Fertilizer recommendation in farming system by using GIS, GPS
and Remote Sensing are used to improve crop production,
fertilizer use efficiency and sustainability of environment.

11. Objectives Of GIS, GPS, RS
 To create fertilizer variable rates map from previous crop
yield and foliar analysis.
 To use decision support system to create information
from the foliar analysis to develop the foliar nutrient
map.
 To estimate the site specific fertilizer rate requirement to
maximize crop production through yield increase and
efficient use of fertilizer input.

12. Benefits of GIS, GPS and RD
The fertilizer variable rates map created will optimize crop
production and save the environment through efficient
fertilizer utilization. By developing the GIS database of the
are, the plantation information can be efficiently utilized
for management, forecasting and planning.
Precision agriculture (PA) is an improved farming system
where technology such as GIS, GPS, RS are used to
improve agriculture practices. The information and
fertilizer rate map created will guide the actual
application in the field such a way that will optimize
fertilizer usage and maximize yield production.

13. Information needed to make fertilizer recommendation
 Representative soil sample result with a equivalent soil
test value.
 Realistic yield goal for field based of recent production.
 Recommendation table with recommendation calibrated
to crop yield of target crop.
