Modern Irrigation, as the name suggests, is the application of water or other liquid substances to the soil in order to sustain crops. It can be grouped into three main groups: Surface irrigation, Furrow irrigation, and Sub-irrigation.

Sub-irrigation

Modern irrigation techniques have evolved over time and are being used in a variety of ways. Some of the modern irrigation methods include sub-irrigation, drip irrigation, micro-irrigation, flood irrigation and overhead irrigation.

Sub-irrigation is a type of irrigation that applies water below the surface of the ground. The purpose of this method is to promote a good rooting environment for plants. It can also be used to flush salts out of the soil.

A sub-irrigation system includes a series of weirs, pumps and canals. It is typically found on permanent grasslands in lowlands.

Sprinkler irrigation

Modern sprinkler irrigation is a cost effective way to irrigate your lawn. It has a number of advantages. These include:

– It is very effective in places with high water tables. The water can be distributed smoothly and evenly, and it also avoids waterlogging.

– It can be used on slopes, uneven land, and sandy soil.

– It reduces windbreaks. This reduces the risk of weed growth and helps keep the crops healthy.

– It can be operated manually or automatically. You can set it to operate at different times of the day or night.

Surface irrigation

Surface irrigation is one of the oldest and most widely used water management techniques. Its main features are low energy consumption and labour-saving. However, its efficiency varies from place to place.

In the last decade, surface irrigation has undergone major improvements. These advancements are the result of the emergence of high-speed microcomputer technology.

Although these advances have been beneficial, there are still practical challenges to be overcome in order to achieve optimal water productivity. Aiming for economic and environmental sustainability is a top priority. To achieve this, farmers and extension services must coordinate their efforts.

Furrow irrigation

Modern furrow irrigation has its limitations, mostly in terms of economics. For instance, it can be expensive to construct and maintain, and the water may not always make it to the other end of the line. The best bet for most farmers is to resort to a conventional drip or sprinkler system.

On the other hand, a modern furrow irrigation scheme can yield high yields. It is especially suited for broadacre row crops such as maize and potatoes. A typical furrow might be 50 or so feet long, with the crop planted on a ridge in the middle.

Heterogeneous approach of the demand and of the efforts (inputs) (outputs) (inputs)

The heterogeneous approach of the demand and of the efforts in modern irrigation has important implications for water policy. It offers insights into the underlying characteristics of services that can help to develop and monitor normative goals for access to water.

To understand the heterogeneous approach of the demand and the efforts in modern irrigation, it is important to consider the role of market goods and services. Various factors contribute to the decision-making process, including the price of available goods, the time required for procurement and production, and the opportunity cost of accessing water.

Efficiency reduces water cost and energy cost per unit of agricultural production

Increasing the efficiency of crop production and water use can have a number of benefits. It can lower the total water cost, increase the amount of water that can be applied, and improve the crop’s yields. However, it can also create additional challenges. For example, the increasing demand for water by the energy sector will put more stress on water resources.

Currently, farmers face considerable competition for water. The agricultural demand for water declined by 56% in Western Europe between 1997 and 2005. This is due to the reform of the Common Agricultural Policy, which has encouraged modernization of farming practices.

Disadvantages

One of the most effective ways to produce cash crops is irrigation. Aside from the ability to raise crop yields, irrigation can also provide nutrients to the plants. Besides, the system helps to re-vegetate disturbed soils in dry areas.

Irrigation is important to human beings because they need water for survival. Without it, civilization would be impossible. The earliest known use of irrigation dates back to the sixth millennium BCE in the Kurdistan region of current Persia.

It is possible that the earliest water systems used buckets to supply water to people. Today, irrigation water can be obtained from rivers, lakes, wells and aquifers. However, there are several disadvantages associated with modern irrigation methods.
