Drip irrigation is one of the most important weapons in our armoury when it comes to conserving the Earth’s limited natural resources while at the same time striving to feed a growing planetary population. The tale of how drip irrigation was discovered and has developed over the centuries to become one of the most important […]
With a growing global population driving a rapid increase in demand for food supplies, the agricultural industry struggles to grow the crops so desperately needed in order to avert starvation in many regions around the Earth. That, and the effects of climate change, which, at current rates, is likely to cause severe droughts, are putting […]
Irrigation has been and will continue to be crucial to the survival and well-being of the human race. Without it, industrial and large-scale agriculture would not be viable, and people would not get the food, vitamins, and nutrition they need for a healthy life. The growing population, global warming, geographical and weather-related issues, and sustainability […]
Increasing crop productivity isn't simply a case of raising output. Yes, if applied correctly, improved farming techniques will certainly raise output. But unless farmers take a balanced approach, it might not be sustainable and could can lasting damage, wiping out any gains in profit and adding to environmental challenges. The Pressures on Agriculture There is […]

The amount of irrigation water that is needed to efficiently water plants and crops is dependent on the crop, the climate in which the plants or crops are grown, and the type of irrigation technique employed. In the same way as with a home garden, there are various designs of sprinklers, some of which are […]
How often you should water grass and for what duration depends on several things, including the type of grass, the type of soil in which it's planted, the amount of sun and rainfall, and for what the grass is used, whether it's a traditional lawn or a sports playing surface. Here in the UK, we […]
The frequency with which farmers should water their crops depends on several factors. They include: The nature of the crop. The climate in which the crop in question is being grown. The type of soil in which the crop is planted. The growth stage of the crop in question. Let's take a quick look at […]
If you put the words “water” and “buffalo” into one sentence, what’s the first thing that springs to mind? Most people would probably answer, “Well, Bubalus bubalas, of course." Actually, they probably wouldn't use its scientific name but would revert to its more popular name - the water buffalo. But if you're an irrigation buff, […]
An irrigation system is the best and most efficient way of supplying the right amount of water to home garden plants and lawns, larger landscaped areas, fields of crops, and golf courses. The costs will vary depending on a range of factors, such as the size of the area to be irrigated, the type of […]
It’s impossible to overstate the importance of sustainable irrigation. Water affects all our lives in so many ways, and the alarming rate with which this limited resource is being used, and yes, wasted, should be of major concern to us all. Although 75% of the surface area of our planet is covered with water, only […]

In 2002 NASA began a mission whose primary task was to study ice sheet depletion. During that mission, the research team discovered that the majority of significant sites losing water were situated below ground. The mission concluded that of the 37 of the Earth’s major aquifers, 21 were on the brink of collapse. In the […]
The quality of irrigation water is important for several reasons. It is instrumental in affecting both the quantity of crops and crop yields. It is also key to maintaining soil productivity and helping to protect the environment. Water quality also has an effect on irrigation systems that transport and deliver it too. In this article, […]
Satellite-controlled irrigation systems have been in use for several decades. To the layman, the term "satellite controller" might conjure visions of a satellite orbiting the Earth and beaming down signals that operate irrigation systems from outer space. However, that is slightly misleading. Satellites are used to send data. This data (such as localised weather forecasting) […]
Golf course irrigation is essential to ensure the various parts of the courses are kept in tip-top condition and to give players the best-golfing experience possible. View our range of golf course irrigation systems here. The summer months are the most demanding in terms of irrigation, especially during protracted dry spells. Of course, the irrigation […]
If you are new to gardening or irrigation, you may not be familiar with the term "grey water." We tend to think of water as falling into one of two categories – clean drinking quality (potable) water that comes into our properties from the mains and sewage water which leaves our properties. But there is […]
Irrigation is one of the key factors that contributed to the civilisation of humankind and the growth of global population. Just under 2 million years ago, the human brain expanded in size, and our guts grew smaller as our earliest ancestors learnt to walk upright. Homo Erectus also learnt how to harness fire to keep […]
First developed as recently as the 1970s, surge flow irrigation is an irrigation technique that has the potential to increase the efficiency of furrow irrigation to the sort of level that is normally seen with drip and sprinkler irrigation. It also opens up the possibility of automating furrow irrigation. The introduction of surge flow irrigation […]
The type of soil a piece of land or a garden area has will determine two things. Firstly, it indicates what type of plants will thrive when planted in it. Secondly, it will govern how well it holds and drains water and, therefore, how much irrigation it will need to keep plants healthy. How Soil […]
