Methods of Irrigation

There are different methods of irrigation. The difference is how water is supplied to plants. The reason why you should design your landscape perfect for irrigation is for the plants to get enough supply of water.

  • Surface Irrigation

This has been in the circulation for thousands of years now. In this method, water travels across the surface of an intended agricultural land, in an organised manner to infiltrate into the soil and wet it. It can be divided into the basin, border strip or furrow.

This is the method most commonly used in agriculture and has been a practised utilised in many parts of the world.

The water levels are most of the time controlled by dykes, usually blocked by soil. This is something you usually see in rice paddies or terraced rice fields, where the method is utilised to flood or control the level in each district field.

In few cases, water is pumped or can be lifted by an animal or human. The efficiency of this method is lower than other forms.

  • Micro-Irrigation

This method is sometimes called trickle, low volume or localised. A system where water is supplied under low pressure using a pipe. This is often used as it offers savings and better control.

  • Drip Irrigation

Drip or for others trickle irrigation works by dropping the water directly at the roots. This is considered to be the most efficient method.

The issue here though is that on steep slopes, it is highly difficult to regulate or control the pressure. To resolve this issue, upgrading the calibrated emitters that are located along the lines of tubing and expanding these using a computerised set of valves can be considered.
