Water-holding capacity is defined as the water retained between field capacity and wilting point. Field capacity is the saturated state of water in the soil that can drain freely due to the force of gravity. Wilting point is the soil water level after its absorption by a plant.
The water that remains in the soil after draining is held by a force greater than gravity. The water level in the soil that can no longer be absorbed by the plants is referred as the permanent wilting point, and this water is strongly attached to the soil particles. The available water to the plant is considered to be 50 percent of the soil's water-holding capacity. The water level that is held by the soil between saturation and field capacity is referred as gravitational water.Learn More
Buffering capacity is defined as the number of moles of strong base or acid needed to change the pH of a liter of buffer solution by one unit. A general buffer capacity estimate is 40 percent of the total sum of the molarites of the conjugate base and acid.Full Answer >
The global water cycle is important because every living organism on earth depends on water to survive. Without water, all living organisms would die very quickly.Full Answer >
Sandy soil is soil comprised of particles that are larger than 0.05 millimeters and smaller than 2 millimeters. Sandy soil retains little water and aerates well because of the large size of its particles.Full Answer >
Ecological balance is a stable state between all plants and animals in an ecosystem, and destabilization of the stable state is ecological imbalance. When plants and animals share a particular habitat, balance must be maintained for the benefit of all organisms.Full Answer >
