The wilting point is the point at which the water in the soil becomes inaccessible to plants and they begin to wilt. Porosity refers to the amount of empty space within soil that can hold water, but it doesn't relate to the point at which water becomes inaccessible. Field capacity refers to the maximum amount of water soil can hold, but it doesn't relate to the point at which water becomes inaccessible. Available water refers to the amount of water that plants can access for growth, but it doesn't relate specifically to the point at which water becomes inaccessible. Unavailable water refers to the water held too tightly by the soil particles for plant roots to access, but it doesn't relate to the point at which water becomes completely unavailable to plants.
