The middle pivot method of watering crops which is regarded as waterwheel method involves employment of a special machine which functions in transferring water in circular patterns to the area being irrigated. This pattern ensures that water is actually distributed in a uniform manner to the entire piece of land. Center pivot irrigation system can actually be used to irrigate a large land within a short duration of time.

One of the benefits using waterwheel method is that it usually uses limited amounts of water to irrigate a large portion of land. The surface methods of irrigation plus the furrow method tends to waste huge volumes of water making a farmer incur a lot of expenses. The middle pivot system saves an individual some significant amount of money through the ability of the system of conserve huge volumes of water.

In reality the ground methods of watering crops are always viewed to be labor intensive methods. Some of these techniques involves digging water channels on the ground while on the other hand the waterwheel method tends to minimize the level of soil tillage which usually occurs while minimizing the runoff of water together with soil erosion which can actually occur while using the ground methods of irrigation.

Less tillage tends to greatly encourage more residue of crops together with organic materials to actually decompose back to the soil while minimizing compaction of soil. This method ensures that crops can be able to actually receive consistent as well as regular water while at the same time minimizing wind drift together with the rates of evaporation.

Another benefits associate with the usage of waterwheel method is that a large piece of land is actually irrigated within a very minimal duration of time. For this to be possible then an individual is supposed to ensure that the land lies on a surface which has flat topography. The center hinge system usually requires some pressure for it to operate effectively. But it should be noted that the amount of pressure which is actually required to the waterwheel system tends to be almost the same with the pressure applied in drip method.

This is simply because the spray is always directed to the air which exposes the water to wind drift. The drop nozzles which are found on the waterwheel method can actually be set just close to the level of ground or even below the level of canopy as the plants continue to grow. Another benefit associated with this particular method is that there is a gentle application of water.

One of such disadvantages is that a farmer tends to actually incur some huge initial costs which are required for the purchase as well as the installation of the middle hinge machine. Maintenance expenses of the machine are also high. It is always argued that these costs are usually compensated when the systems irrigates several hectares of land within a short duration of time.

In reality the waterwheel method is basically regarded as very unique method of watering crops as it water plants using circle patterns. The farm land is basically covered by the circular patterns which are achieved by transferring the center hinge machine which functions in supplying the irrigating water in rotary motions.
