Precision agriculture in Punjab involves the use of technology for:

Efficient water use
Soil nutrient mapping
Pest control
All of the above

The correct answer is: d) All of the above

Precision agriculture is a farming management concept based on observing, measuring, and responding to variability in agricultural production factors within the field, such as soil type, moisture, plant growth, and pest populations. This is achieved through the use of information technology, sensors, software, and other technologies.

Precision agriculture can be used to improve the efficiency of water use, soil nutrient mapping, and pest control.

  • Efficient water use: Precision agriculture can be used to map the variability in soil moisture within a field. This information can then be used to apply water only to the areas that need it, which can save water and improve crop yields.
  • Soil nutrient mapping: Precision agriculture can also be used to map the variability in soil nutrients within a field. This information can then be used to apply fertilizer only to the areas that need it, which can save fertilizer and improve crop yields.
  • Pest control: Precision agriculture can also be used to monitor pest populations within a field. This information can then be used to apply pesticides only to the areas that need it, which can save pesticides and improve crop yields.

Precision agriculture is a valuable tool for farmers who want to improve the efficiency of their operations and reduce their environmental impact.
