Precision Agriculture - Revision

Precision Agriculture involved..

• information

• parameter

• technology

• weather

Answer explanation

Precision Agriculture involves the use of information and technology to optimize farming practices, making choices based on data and advanced tools.

Three criterias required to implement Precision Agriculture, EXCEPT:

• Ability to determine spatial and temporal variability of soil condition

• Ability to gather information after harvesting

• Ability to identify and quantify such variability

• Ability to rellocate inputs and adjust management

Answer explanation

Precision Agriculture requires the ability to determine spatial and temporal variability of soil condition, identify and quantify such variability, and relocate inputs and adjust management. Gathering information after harvesting is not a criteria for implementation.

The following process involved in Precision Agriculture, EXCEPT:

• Data collection

• Evaluation

• Changing Implement

• Diagnostics

• Field operation

Answer explanation

The process of Precision Agriculture involves data collection, evaluation, diagnostics, and field operation, but does not include changing implement.

Global Positioning System is..

• use for weather observation on Earth

• able to detect changes in 12 hours time

• a regional navigational satellite system

• a series of satellites placed in orbit around the Earth

Answer explanation

Global Positioning System is a series of satellites placed in orbit around the Earth.

The other Global Navigational Satellite that exists today is called as..

• Beidou

• Quasi-Zenith

• GLONASS

• IRNSS

Answer explanation

The correct answer is GLONASS, as it is another Global Navigational Satellite System currently in operation.

The signal from the satellite can cross over the following, EXCEPT:

• building

• cloud

• football field

• dessert

Answer explanation

The signal from the satellite can cross over clouds, football fields, and deserts, but it cannot pass through buildings. Therefore, the correct answer is building.

Which of the following is NOT a proximal sensing?

• pH meter

• aerial photo

• SPADmeter

• water level sensor

Answer explanation

The correct choice is 'aerial photo' because it is not a proximal sensing method like the other options which directly measure parameters in close proximity to the object of interest.

3 types of Model in Interpretive Techniques are:

• Descriptive modeling

• Productive modeling

• Predictive modeling

• Prescriptive modeling

Answer explanation

The correct types of Model in Interpretive Techniques are Descriptive modeling, Predictive modeling, and Prescriptive modeling.

Below are the correction services available for GPS. Recognise the INCORRECT service.

• Real time kinematic

• Differential global positioning system

• Virtual reference station

• Glonass

Answer explanation

The incorrect service is Glonass, as it is a Russian satellite navigation system, not a correction service for GPS like the other options.

Which of the following are the process of determining the location of an object using GPS.

• Trilateration

• Trigonometry

• Triaxial

• Triennial

Answer explanation

Trilateration is the process of determining the location of an object using GPS by measuring distances from the object to three known points. It is the correct choice in this context.
