rhino pipe 2

All of the Rhino Pipe collection, is manufactured kink free and bound in ropes to absolutely minimise the possibility of a kink forming where the pipe is banded. However, the issue regarding the kinking generally happens post production as the pipe heats and cools during the average day and eventually a kink can occur, even if the pipe is just standing in the yard!

This is tough to legislate against, however we at Ripple Aquaplast have taken strides to ensure the quality of the pipe for our customers. We have decided to increase the wall thickness by approximately 10% which will add considerable strength to the coiled pipe. Therefore incidents of kinks, although not completely negated, have been dramatically reduced.

frost protection blueberry

The natural and agricultural environment is highly affected by climate change. The leafing out, blooming, flowering, ripening of fruits, water balance and so on are all very susceptible to stress and severe damage as a result of extreme weather.

One of these extreme weather events is the drop of temperatures below 0°C, namely frost. When these drops in temperature occur out of season, the plants are ill-equipped to cope with it on the physiological level, and they suffer severe damage as a result.

 

frost protection latent heat

There are two kinds of frost:

 

Advection Frost (Windy Frost or Black Frost) occurs when a cold air mass (cold front) moves into an area, bringing freezing temperatures. Wind speed is usually above 8hm/h. Possible protection against this kind of frost is very limited.

Radiation Frost occurs when, with a clear sky and calm winds, the temperature near the surface of the earth drops to below freezing point. As temperatures drop, the cold air flows downward to lower topographic areas. That is where most of the damage is seen. Efforts have been made to come up with a solution for this kind of frost; a way to alleviate the damage caused by the low temperatures. In order to do so, we utilise the same basic laws of nature that play an important role in creating the frost itself.

Many methods have been used to protect fields and plantations from frost, the use of sprinklers was found most effective.

 

  1. Overhead Full Cover

 

 

Overhead sprinkler irrigation is a very common practice in frost protection. Overhead irrigation provides excellent frost protection at temperatures of -7°C and lowers if the application rates are sufficient and the application is uniform.

Conventional overhead sprinkler systems use standard impact sprinklers to completely wet the plants and soil. Sprinkler distribution uniformity is important to prevent inadequate coverage, which might result in damage. For frost protection, specially designed springs are often used, which are protected by an enclosure to prevent the icing of the heads. In short, the conventional overhead full cover method, when applicable, provides excellent protection and is the most common and safest frost protection solution. Widely used in open field crops, all kinds of orchards, blueberries etc.

 

2. Targeted Micro Sprinklers

 

frost protection micro sprinklers 2

Targeted micro sprinklers spray the water directly onto the plants, with smaller amounts of water falling between plant rows. Usually a single micro-sprinkler is positioned above a single tree. A big advantage of using targeted sprinklers is that they commonly have much lower flow rates compared to conventional sprinklers. In other cases, like some of the fruit wall crops, an over lapping spacing between the micro-sprinklers is applied and a continues wetting zone is achieved along the relatively narrow row of trees, giving perfect targeted protection.

One of the advantages of targeted micro-sprinklers is their ability to protect larger areas with a given amount of water. On the other hand, one of the limiting factors of this kind of frost protection is the possibility of water freezing inside the narrow tubes leading up to the emitters. The flow velocity will determine the point of freezing.

 

3. Strip Method

 

frost protection strip method 2

In many cases, especially in apple orchards, there is a 3-metre gap between the rows of the trees, and the rows themselves are very narrow, creating a “fruit wall” configuration. Other crops, such as berries, grapevines, or vines in general, are also grown in narrow rows. If we could irrigate only the row itself, without applying water to the spaces between the rows, we would be able to save huge amounts of water, making it possible to protect a much larger area at the same time.

The bottom line is precision. Only the plants need to be protected; not the roads or the spaces between trees.

The NDJ flipper allows you to do all that with flying colours! While applying significantly less water per hectare, we provide the same exact protection.

However the grower/irrigation manager should be well versed in its use, as the Frost Protection method requires technical knowledge to ensure its used correctly and to lower the risk of complications.

The Story

Ripple Aquaplast had our 10 minutes of fame on the television last night, our system design and products where shown on the BBC’s “Supermarket Secrets”. Discussing the importance of creating a Blueberry native to Britain.

Due to the serge in demand over the past years for blueberries, supermarkets are starting to try and source this “super food” locally. However, at the moment roughly 90% of the UK’s blueberries are imported from abroad.

With over £3 million being invested into the research of a native British blueberry, Dr Susan McCallum from The Jame Hutton Institute in Scotland, hopes to bring this vision into reality over the next eight years.

The James Hutton Institute has chosen the Bilberry, native to Europe and the UK, for its primary focus. Rich in anthocyanin, which helps reduce cardiovascular disease, and vibrant in colour, the Bilberry has it all. Well at least in small quantities, the lack of size and yield the crop creates means that Dr Sarah McCallum has to turn to crossbreeding, to create a more substantial fruit. Using DNA profiling to gather the best traits from US blueberries, which our larger in both size and yield, mixed with the colour and health benefits of the Bilberry, to create a Blueberry perfect for the British climate and consumer.

Where do we come in!

Peter Robinson, our technical expert, was tasked with creating a drip system that would provide perfect fertigation to each and every pot. With over 6,000 seeds being used in this project, with most seeds being a different variety to the next, this caused some variability in the design set up.

We provided the following:

  • 2lph 50cm NDJ Click Tif dripper sets
  • Automated irrigation control
  • Fertiliser Injection Unit

Getting your drilled pipe specifications right is important. This is why we give this topic a lot of thought at Ripple Aquaplast. After various meetings and discussions, we have managed to come up with a original formula for the raw material and hence the extruded pipe, which we are very satisfied with for the UK market. Manufactured by NaanDanJain Spain, we have made sure that not only does the pipe last the course of the dripper, but also, that the drip holes are precisely measured for leak proof operation.

Effectively, we have asked NaanDanJain to slow down the production speed, to minimise the risk of oval or mispunched holes.

Not only this, as the image shows, we have date stamped with the production date each meter of the pipe alongside a production code so each piece of pipe is fully traceable in the unlikely event of any issues during its lifespan.

punched pipe

Another one of the key elements to be aware of with the production of the pipe is the quality of the coiling machine. The pipe is effectively under very little torsion once coiled. This is a balance of the actual coiling process and the quality of the material being produced. This results in effectively zero oval or strained holes which allows the pipe to be sensibly stored waiting to be used in the field.

It is often underestimated the detrimental effect of coiling the pipe and the effect it can have on the integrity of the drilling. The resulting leaks, even if small, completely negate the CNL operation of the system with the resulting detrimental effect on the crop.

The product is available to order now! Our standard lengths are 20cm and 25cm in 300m coils. Of course all spacings are available to order. Both 20mm and 25mm diameter LPDE is available. So either call the team on 01925 818499 or follow this link: https://goo.gl/5GwS5T

Remember to specifically ask for NaanDanJain drilled pipe from Ripple Aquaplast and be assured of a quality product for prolonged, trouble free life.

sand filter

 

We all know if you want to produce the most yield, ensure your crops are fed correctly. This doesn’t just mean having the best quality pipe or sprinkler, if your water isn’t up to scratch then nor will the rest of the system.

The water used in most irrigation systems can contain contaminants such as silt, sand, algae and other decaying organic matter. Depending on the type of irrigation system being used, the level of filtration required changes. An example of this being Drip Irrigation, as it needs much finer filtration than compared to spray irrigation, to prevent blockage.

Manual

Manual filters require regular user inspection and cleaning. Some manual filters are fitted with a brush or scanner assembly which allows them to be cleaned without disassembling.

Automatic

Automatic Filters are fitted with a timer and a pressure differential switch. When the pressure differential reaches a pre-set value, the filter goes into a backflush cycle and cleans itself. This type of filter would primarily be used for automatic irrigation systems.

Sand Filter

Sand filters are suitable for both inorganic and organic contaminants. They are tanks filled with sand or gravel media. Water passes through the bed of media and particles are trapped. Sand filters offer a much bigger surface area and as such can usually provide an effective filtration within the water velocity recommendations of the manufacturer. Cleaning is achieved by reversing the flow of water through the tank to lift and separate the sand. Trapped contaminants are purged to waste as the water flows through.

Screen Filter

These are the least expensive and most common filters. They work well removing sand from water, due to the very fine stainless-steel mesh that traps particles. In situations when you need to remove copious amounts of organic material from water you have better choices. The organic materials tend to crush on the screen and are hard to remove.

NDJ trip 2

New Products and New Designs

Earlier in May, NaanDanJain France invited Stewart Penny and Simon Taylor of NDJ UK to hold commercial and technical discussions regarding the growing use of sprinklers in orchards in France and in what applications they are used.

Here we see a large frost protection system in Meauzac near Toulouse in the South of France. They take frost protection seriously here as they can have frosts of around -7’c and as we were driving around you can see quite clearly the farmers who took the risk and this year have lost the gamble.

This particular grower has 150 acres of apples and 50 acres of cherries. All the areas can be frost protected at once and this year he will see the benefit of the investment as they have seen -6’c when the system, was called into action. The system is actually triggered by a simple “wet sock” frost stat. The sprinklers are of course NDJ, from the 200 series the robust brass sprinkler with the red protective cover.

Simon Taylor of NaanDanJain ensuring long term customer satisfaction!

It’s that time of the year when Simon Taylor of NDJ visits the rigs supplied and installed via Aquaplast and runs some diagnostics and checks.

This rig on the south coast is feeding a large area of blueberries and has 8 feed legs ( 4 sets of 2 ) and two pH probes to ensure super accuracy of the pH, as blueberries are very sensitive.

The job is made more interesting by the use of sulphuric acid instead of nitric on the request of the agronomist and the fact that the valve sections are over 100m3 in size!

With NDJ feed rigs up and down the country, Simon is always busy, however with remote internet connectivity, many queries are answered remotely, but it is always nice to get “hands on” from time to time.
