2. Field Capacity

3. Fluid Conductivity

4. Fertility Capacity

The correct answer is: Field Capacity

In the context of irrigation, the abbreviation FC stands for Field Capacity. This term refers to the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of water uptake by plants has slowed. Field Capacity is a crucial concept in irrigation management as it helps in determining when to irrigate and how much water to apply. Understanding Field Capacity is essential for effective irrigation scheduling since it provides insights into the soil's ability to retain moisture available to plants. When the soil reaches this capacity, it means that it has sufficient moisture to support plant growth without the risk of waterlogging or drainage issues. This knowledge helps irrigation professionals manage water resources efficiently, ensuring that plants receive adequate hydration while minimizing waste and potential environmental impact.
