Why is drip irrigation important

The drip lines are much smaller in diameter then the supply lines. You can tap the supply lines as many times as you need depending on the number of rows, or raised beds you have.

They have diagrams on their site that you can choose from, as well as customize to get the exact layout you want. They also have helpful how to videos that will tell you specifically how to install the kit you purchased.

Lastly, I find DripWorks kits to be the easiest to install and also the highest quality. Their fittings are strong and rarely leak. The only thing I would add is an automatic watering controller as mentioned above. These timers allow you to automate your watering so you can set it once and forget about it.

I like the idea of having a supply line that leads to the drip lines. I could see that being a good way to make sure that enough water flows to the far drip lines.

My husband and I were thinking about getting an irrigation system installed for our lawn so that we can save time on yard work, and we were wondering what type would be best. The combined length of the mainline and sub-main should not exceed feet. The valve controls water flow into the system and can be set for either automatic or manual control.

Pressure regulators are needed if the water pressure is over 40 pounds per square inch. If you do not know your water pressure it is a good idea to install one just in case. Filters keep dissolved substances in your water from clogging the emitters over time.

Install filters either at the emitters or at the water source to protect both the valve and pressure regulator in addition to the emitters. It is best if the filter has at least a mesh screen or higher. Tubing adapters and fittings are used to attach the drip tubing to the rest of the system. It is important that these are the right size for the tubing to prevent them from blowing apart under pressure. Drip Tubing and Emitters Drip tubing is a polyethylene tube with emitters placed along the plants.

The emitters release the water from the drip tubing. Drip tubing and emitters come in various types and diameters depending on your needs.

The length of a single drip tube should not exceed feet from the point where water enters the tube. You will need to stake the tubing to keep it from moving. This helps to prevent clogging and rodent damage. Emitter Spacing and Design Emitters can be spaced evenly for row crops, and this design is known as an emitter hose.

Emitters can also be spaced intermittently for plants spaced further apart, such as trees, shrubs and perennials. With an emitter hose, the emitters will generally be spaced about 18 inches apart. When watering trees and shrubs, there should generally be two emitters per plant. The end cap is placed at the end of the drip tubing to prevent water running out the end.

Basic Operation and Maintenance Drip irrigation can be set to run automatically, like sprinklers, or controlled manually.

Manual operation allows you to take advantage of rainfall before applying unnecessary water. For more information on proper watering, see Water Wisely. Because small amounts of water are applied slowly, drip irrigation is designed to run daily unless it rains. Water is applied either once or twice a day. Early morning is the best time to water because there will be less evaporation.

Now there is growing interest in the technique and many efforts are being made around the world to develop low-cost, simple, drip irrigation systems suitable for smallholder farmers. This handbook presents some of these drip irrigation options that can be promoted by extension officers in eastern and southern Africa.

It describes the most interesting small-scale low-cost drip irrigation methods of which the author and the other contributors have practical experience.

It also gives a brief overview of methods that have been used successfully in other parts of the world with details of how to obtain further information about them or order equipment. The drought of and the famine that followed in politically instable Somalia highlighted the vulnerability of the lowlands of the Horn of Africa.

It is a story revisited with high frequency — , , and Climate variability is easily mentioned as the main attributing factor. Clearly it is — but there is also extensive land use change, because of the widespread invasion of invasive species prosopis in particular and the decimation of natural wood stands for charcoal production particularly in Somalia. In the Afar lowlands in Ethiopia food aid has become part of the livelihoods, with most of the people dependent on it — including reportedly middle class families.

There is a growing realization that water resource development — appropriate to the context — has to have a place in addressing food insecurity in the Horn of Africa. This paper focuses on irrigation policy and practice in the arid lowlands of the Horn that have been hit hardest and most frequent in the drought episodes. There are presently no formal guidelines for the use of greywater in South Africa. This paper presents the rationale and framework of a guidance document for the sustainable use of greywater to irrigate gardens and small-scale agriculture in South Africa, developed under the auspices of the Water Research Commission.

This book is written for practitioners, researchers and graduate students in environmental and public health, sanitary and agricultural engineering, and wastewater irrigation management in developing countries.

In particular, it should be useful for all those working to assess and mitigate health risks from the use of wastewater and faecal sludge in agriculture, under conditions where wastewater treatment is absent or inadequate to safeguard public health.

Responses were analysed to determine the technological, socioeconomic and cultural suitability of the systems. The survey focuses on the determinants of success and failure and identifies knowledge gaps that influenced either adoption or disadoption by beneficiaries. A cost-effectiveness analysis is also undertaken to compare drip kits with traditional bucket irrigation. Finally, the study draws some conclusions and lessons that can be extrapolated beyond Zimbabwe to ensure that interventions aimed at smallholder-irrigated gardens have more sustainable impacts.

This paper analyses solar-powered drip irrigation as a strategy for enhancing food security in the rural Sudano—Sahel region of West Africa.

This paper aims to fill a research gap in India by focusing on adoption patterns of micro irrigation and the economic impacts on farm households. This study is based on primary and secondary data collected from nine states.

It seeks to establish a relationship between landholding size, area under micro-irrigation, and net benefits. Farmers' suggestions for making micro irrigation more accessible are also noted. Despite its proven benefits, micro-irrigation has been slow to realise its potential in India. Following the recommendations of the Micro-irrigation task force in , a tiered set of subsidies was put into place for micro-irrigation. The models set up in Andhra Pradesh and Gujarat have been considered the most successful.

This paper compares these two models using several parameters and comes up with a set of recommendations for replication elsewhere. The study aimed at assessing the feasibility of using urine as a fertilizer and drip irrigation technology to address food scarcity that has hit Uganda as a country of late. The study revealed high rates of return for a farmer who chooses to practice drip irrigation and fertigation.

This however gives best results with effective disease control. This PDF-presentation shows photos of drip system components and installations in Nepal. Simple low-cost drip irrigation is practical and affordable for smallholder farmers.

It has been successfully used in India and is becoming more popular in other southeast Asia and sub-Saharan Africa. This chapter drip irrigation manual provides basic, step-by-step procedures for installing simple drip irrigation systems for different crops, climates, and soils.

This website is an attempt to distil current information on irrigation methods that might be appropriate, and to offer some ideas on the possible adoption and adaptation of such methods by small-scale farmers in the semi-arid areas of sub-Saharan Africa. Water for irrigation: different irrigation techniques and tips for using water for irrigation. The website of International Development Enterprises IDE contains many technology- documents, photos and information about the water and agricultural section in developing countries.

What is a perspective? Executive Summary Drip irrigation is a technique in which water flows through a filter into special drip pipes, with emitters located at different spacing. Ability to irrigate irregular shaped fields. Levelling of the field not necessary.

Moisture within the root zone can be maintained at field capacity and minimised soil erosion. Highly uniform distribution of water i. Usually operated at lower pressure than other types of pressurised irrigation, reducing energy costs. Expensive initial cost can be more than overhead systems commercial system. The sun can affect the tubes used for drip irrigation, shortening their usable life.

If the water is not properly filtered and the equipment not properly maintained, it can result in clogging. Drip irrigation might be unsatisfactory if herbicides or top dressed fertilisers need sprinkler irrigation for activation.

Systems require careful study of all the relevant factors like land topography, soil, water, crop and agro-climatic conditions, and suitability of drip irrigation system and its components. Without sufficient leaching most drip systems are designed for high efficiency, meaning little or no leaching fraction , salts applied with the irrigation water may build up in the root zone.
