The Most Modern Methods of Irrigation
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 […]
The Most and Least Efficient Methods of Irrigation
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 Long and How Often Grass Should be Watered
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 […]

How to Prime an Irrigation Pump
One of the best ways of ensuring the growth of healthy plants and vegetables is to ensure you use an appropriate irrigation method. Whether you are a home gardener or farmer, one of the most common ways of irrigating plants and crops is with the use of an irrigation pump. There are several different types […]
How Over-irrigation Can Be Damaging to Soil and What to do to Prevent It
Getting the amount of irrigation that farmers and gardeners give their crops and plants right is crucial. Not enough, and plant growth and health will be adversely affected. In worst-case scenarios, it can kill plants. But over-irrigation has its problems too, both in terms of plant health and the condition of the soil. It is […]

Which Irrigation Systems are the Most Evaporation Efficient?
Liquid water that pools on varying surfaces such as lakes and rivers, the ground and the leaves of plants is converted into water vapour by a process we know as vaporation. This water vapour is then removed into the atmosphere, and this entire process is what we know as evaporation. For evaporation to take place, […]
How Much Water Crops Need and Why
The UK agricultural and farming industry only contributes a relatively small amount to the national economy and employment stakes. However, it uses nearly 75% of the total land area and produces many important benefits for the population, the most obvious of which is the food it provides. Some of the side benefits that the agricultural […]
Add 2-Wire Decoder Irrigation to Your SCADA PLC
PLC (Programmable Logic Controllers) may now be enabled to run irrigation using 2wire decoders. This is useful where the PLC is already doing control, like waste-water or pumping, but irrigation or water spreading is also needed. With Irrigation added, it can then be incorporated into SCADA. Currently, to control irrigation, multi-wire outputs (usually relay) need […]
What is Subsurface Drip Irrigation
A subsurface drip irrigation system is a highly efficient, low-pressure network that utilises drip tubes or tapes to deliver water directly to the root systems of plants and crops. The concept of drip irrigation, which would lead to subsurface drip irrigation, was the brainchild of a Polish-Israeli inventor, Simcha Blass who developed the idea together […]
How to Maintain Golf Course Bunkers
Golf course bunkers first came into being on links land due to "natural" occurrences. Originally, the ground was open farm or common land.
