2. What is yield monitoring and mapping?
 Initially introduced in the early 1990s, yield mapping is a precision-agriculture
tool that involves the process of collecting georeferenced data about the
different level of yield as well as moisture content , in different parts of the
same field.
 During harvesting, the harvester measures these parameters using several
sensors, and the measurement along with the location where the measurement
was taken is recorded using geo-spatial tools. This information is used to
generate a map which makes it easier for visualization by the farmers.
 The single measurements of yield characteristics are then classified on specific
zones or ranges using different colors to produce a range map or a zone
classified map.
 The number of such classifications can be set according to the needs of the
farm.

3. What are the basic components of a
yield mapping.
 The application of yield mapping or yield monitoring in farmlands lets farmers
optimize their production by directing inputs to specific areas within the farms
that need them the most.
 The basic components of the more common grain yield-mapping system
include:
 Grain flow-sensor: A grain flow-sensor fitted on the harvester is used to
determine the actual quantity of grain being harvested as the harvester moves
across the field in real-time
 Grain moisture-sensor: Grain moisture-sensors are also included in the
grain combines that measure the capacitance of the grain. This is done to offset
the variations in grains caused by environmental factors like rain, temperature,
etc.

4.  Ground speed-sensor: It is important to measure the speed of the combined
harvester for accurate results. This can be done by using either GPS-based
information or an actual ground speed sensor that measures speed from wheel
rotation.
 GPS-receiver: For geo-coding the measurement made by other sensors, a
GPS-receiver is fitted on the grain combine which constantly gives locations to
each measurement taken.
 Yield-monitor display: It is the component that is fitted inside the cab of the
harvesters where the operator/farmer is located. This provides him/her with
real-time processed data on a display screen that is being continuously
generated by several sensors.

5. What is the role of yield mapping in
precision agriculture.
 Precision agriculture is the use of technology and data in farming operations so
as to determine the type of farm inputs, the level/amount of those inputs, and
the precise location within the farm where those inputs should be applied in
order to reduce costs, increase productivity and maximize efficiency.
 Yield monitoring is used in precision agriculture because it helps to identify
measure and describe the intra-field variability within a cropping system which
is exactly what forms the basis of the concept of precision agriculture.
 The yield monitoring provides variable data within a single field.

6. This data is generated as a result of a complex interaction between several
factors occurring within a farm like a farm management methods,
environmental factors, and climatic factors.

7. What are the benefits of Yield mapping?
 It can be beneficial to make decisions about:
 Soil tillage: Both lack of tillage and excessive tillage can reduce the production
of a farm and this can occur on small patches on large farms, especially if a
systematic tillage operation was not carried out. Identifying these areas is
critical in ensuring a better tillage operation in the next cycle.
 Irrigation Requirements: One of the major components of yield monitoring
is moisture content. As a result, yield maps are a valuable asset to making
irrigation plans.
 Crop Rotation: Yield mapping can give an idea of the appropriate crop
rotation as a whole.

8. Who can help with yield mapping?
 Evidently, yield monitoring can help farmers be better at farming. These
powerful tools or processes are obtained by combining software and hardware
from varied technological fields like geo-informatics, sensors, digital
cartography, Internet of things (IoT), processing, and analytics. While it might
be overwhelming to understand the details of all the components to farmers,
the end-user experience of the results can be easily visualized and understood
by all. However, because of the level of precision that is required, it is important
to rely on a highly capable service provider like GeoPard.
 GeoPard offers a dedicated agri-solution named Yield Data that lets farmers
construct field management zones on maps.
