Things To Know Concerning Center Pivot Irrigation System

By Brenda Patterson


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.

This method of watering crops is usually viewed to use lesser amounts of water when compared to the surface methods together with the furrow irrigation. Due to this water conservation technique the farmer is therefore saved some significant amount of expenditures. This method is also viewed to reduce costs of labor when compared to the ground techniques of irrigation.

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.

Due to this fact then there is a significant decrease of soil erosion which depletes the soil nutrients which are beneficial to crops. When there is minimal tillage on any land then it implies that organic materials together with residue crops can be able to decompose effectively while reducing the soil compaction.

Additionally this method of watering crops gives a farmer a chance to determine the amount of water which plants can be able to receive and the time which the plants should be watered. This method also ensures that there is minimal wastage of water. In most of dry areas both evaporation of water together with drift of wind tends to cause a greater loss of water to planted crops.

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.

The drip irrigating method usually makes use of pipes which are buried in the soil and they only last for a period of six to eight years. Waters mains especially in the drip type of irrigation tend to however remain very intact for a subsequent use.
