Precision irrigation techniques use technology to:

The correct answer is: d) All of the above.

Precision irrigation techniques use technology to optimize water application based on soil moisture, schedule irrigation based on crop needs, and reduce water wastage.

• Optimizing water application based on soil moisture ensures that plants receive the water they need, when they need it, and no more. This can be done using a variety of methods, such as soil moisture sensors, weather stations, and irrigation scheduling software.
• Scheduling irrigation based on crop needs takes into account the type of crop, the stage of growth, and the weather conditions. This ensures that plants receive the right amount of water at the right time, which can help to improve crop yields and reduce water costs.
• Reducing water wastage is essential to ensuring that water resources are used efficiently. Precision irrigation techniques can help to reduce water wastage by eliminating over-irrigation and by targeting irrigation to specific areas of the field.

Overall, precision irrigation techniques can help to improve crop yields, reduce water costs, and protect water resources.
