The steady stream of visitors.....

Part of the role of The National Precision Growing Centre is to educate both industry practitioners as well as the wider public in how precision growing is undertaken.

This week we had a diverse range of visitors from those with a hobby background in horticulture, right up to one of the leading exponents of precision growing.

We firstly welcomed 34 members of the Springvale Garden Club to observe first hand how a commercial glasshouse operates. The group recieved an explanation of both climate and irrigation management from staff member Tony Bundock, whilst our trainee Sara Nour, gave a guided tour around the crop growing area.
 
The group finished their tour with an opportunity to buy some of our wonderful fresh tomatoes!



At the other end of the scale, we welcomed Grodan's Andy Lee to Cranbourne this week as he tours Australian as part of his customer support program. As ever, Andy was a wealth of knowledge and gave us some great guidance in terms of crop and climate management strategies.

GRODAN introduces new wireless, multi-sensor measuring system for substrate growing

Based on professional growers’ needs for higher accuracy and reliability in monitoring water content (WC), electrical conductivity (EC) and temperature in substrates, GRODAN is now introducing a state-of-the-art innovation: the GroSens® wireless, multi-sensor measuring system.


When GRODAN asked its customers what challenges needed to be overcome to achieve precision irrigation, it quickly became apparent that there was a need to measure WC and EC more accurately and at multiple locations in the greenhouse. “The current WCM meters still work well and are used a lot; however in the past 15 years a lot of technological developments have taken place.” explains Vincent Deenen, Director Marketing and Development at GRODAN. “After intensive research, we have now designed a solution to precisely match the growers’ needs, the GroSens system”.

 
The newly introduced GroSens® system: making precision irrigation possible

The GroSens benefits The wireless GroSens system enables 24/7 real-time insight into the WC, EC and temperature of the stone wool substrate. It contains multiple sensors that are designed with double the number of measuring points compared to its predecessor, the WCM II. Based on statistically reliable trials, GroSens measures the WC and EC at least 5 times more accurately than existing Water Content Meters (WCM). The fact that there are multiple sensors, and thus more measurement points in the irrigation section, leads to more reliable and representative WC and EC figures. The wireless sensors allow tremendous flexibility in where you can measure in the greenhouse and they are easy to install. The GroSens system is modular; the basic set consists of 3 Sensors and can be extended with more Sensors, to suit each grower’s needs. In short, GroSens is an ideal measuring tool for growers who want to take Precision Growing to the next level.
 
“The GroSens system, in combination with GRODAN stone wool substrate products and advice, is the best way of achieving optimum results in production and cost savings. Launching this system is another step in the GRODAN Group’s strategy of making Precision Growing possible for growers,” concludes Deenen.

The patented GroSens system will be introduced to the market gradually and will eventually replace the current GRODAN WCM’s. For more information, please visit he GroSens page

Haifa Fertilizer Seminar

Tuesday saw us co-hosting a seminar with Haifa Australia at our Cranbourne Campus, which focused on the use of soluble fertilizers in hydroponic growing.


The event was extremely well supported with over 35 delegates attending from a wide range of industry practitioners, and many of the delegates also came from Interstate -  with South Australia, Queensland, New South Wales, Tasmania and Victoria all being represented.

The seminar focused on the technical aspects of fertiliser choice and in particular, the need to formulate recipes that not only meet specific fertilizer values, but also provide a 'balanced' recipe in terms of +ve and -ve ions.

 
Shaul Gilan

Haifa staff members, Shaul Gilan and Peter Anderson were the presenters and provided some challenging and thought provoking content for the delegates, whilst promoting a relaxed learning atmosphere.

Peter Anderson

The morning sessions culminated in some fairly hefty mathematical and chemical theory before the delegates were given a demonstration of the SMART software that has been developed to aid growers in formulating recipes.
In the afternoon the delegates moved to the glasshouse facility where their theoretical skills were once again challenged, along with some practical demonstrations of fertiliser mixing at differing water temperatures.
Delegates from DPI Bundoora check their maths!

The delegates were also able to take a first hand look at the fertigation system and water recycling systems utilised within the National Precision Growing Centre, to see best practise in action.
Following the success of this event in Melbourne, we are now looking to take the seminar 'on the road' and we are now making plans to showcase the seminar in Queensland, New South Wales, South Australia and Western Australia.
If you are interested in attending a future event in one of these states, we would invite you to express your interest by sending us an e mail via tony.bundock@chisholm.edu.au

Recycling of our Stonewool

At the recent Protected Cropping Australia Conference, Chisholm and Grodan held an informal meeting for growers to look at potential recycling options for growers who are using stonewool as a medium.

Whilst our European colleagues are well served in this area with Grodan recycling their product for producing bricks, the Australian market is hindered by the lack of critical mass of growers in localised areas. 

The meeting soon identified that whilst a Nationally based total solution would be great, the reality was that growers are seeing local solutions to recycle the product. And the recycling issue is not just limited to the stonewool, with growers looking for whole of enterprise solutions that will allow them to process crop trash as well.

On a more local level, we have been looking at how we might utilise our old stonewool slabs for a secondary use. Trainee Sara Nour and Diploma student Marcus Long have been looking at trials involving adding increased percentages of green matter to shredded stonewool with the aim of producing a composted green waste product with stone wool as an additive. These trials are in the early stages and we will be looking to publish their findings as time develops.

After we had removed the plastic, the initial issue was how to shred the slabs. We did investigate using a commercial tree chipper, but the trials with this style of machinery were varied to say the least! The action of the chipper was very aggressive and the dry slabs turned to dust - and blew away!, whilst slabs with a SMC of approx 30% or greater just clogged up the machine.

Our second attempt at shredding the product involved a more agricultural solution. Certificate 3 students Mark Lim, Robert Bounday, Graham Elsworth, Aaron Jackman and Di Lester have been involved in this process, and this saw them running a tractor mounted rotary hoe across the slabs with a PTO speed of 540 RPM. 


The rear shield was initially kept up to allow for a more open breaking process of the slabs and then lowered to mill the product.

The results were promising in that we were left with a fairly fine product that we now believe we can utilise as either a generic mulch for tress and shrub beds, or a potentially useful product that we can use in relation to 'vertical wall landscaping' as part of our Landscape students developing project.


So our 'local solution' seems to be working well in terms of processing, and we will keep you posted on the results of the 'secondary use' viability. 

For further information on any of the processes that we are experimenting with, feel free to contact us via e mail at tony.bundock@chisholm.edu.au

Benefits of controlled environment horticulture

We are often asked what are the benefits of using a controlled growing environment? 

Well there are many benefits which include having full control of your growing environment, which ultimately enables you to manipulate the various climate factors within a greenhouse to give your plants optimum growing conditions. This includes the ability to produce internal climates that allow you to grow crops out of their 'natural' season. For example, long term Tomato crops are now grown across a 51 week period, and this sees fresh tomatoes being on the market all year round as opposed to just the warmer months.

A structure, such as a greenhouse, also protects your plants from external 'infuences' such as rain and wind.

In Melbourne last night we had some very high winds which placed a high cooling effect on our greenhouse. However with the use of our energy screens and heating system we were still able to provide a stable climate for the plants, which were kept safe and warm within the greenhouse itself. And we are pleased to report that the structure is still in one piece as well!

The winds we experienced at the Cranbourne Campus last night peaked at 16.8 metres per second, or the equivalent to 60 kilometres per hour. And in the scheme of things this wasn't to bad. Gusts of 96 km/h were recorded in the inner city suburb of St Kilda and winds reached 92km/h at Melbourne Airport.



The graph shown above was generated on our Priva Intergo climate management system this morning and you can see the general wind speeds across the 24 hour period that we have just experienced.

With the strong winds set to return on Sunday we have our fingers crossed that neither ourselves or other growers suffer any structural damage.

GroLog App from Grodan

With technology changing almost daily, we have been alerted to a new App from Grodan called GroLog. The following explanation is from GroLog website and gives you an overview of this technology.


The GroLog from Grodan is an app that assists growers in effectively managing their crop areas. Keeping a detailed crop log is vitally important to a successful crop and with the GroLog it has never been easier to keep your crop dialed in! 

Do you have several crops you need to track at the same time? No problem - simply create a separate ‘grow’ for each of your crops. The GroLog allows you to select exactly what data you would like to monitor in each grow, such as:
-Nutrient Solution: pH, Parts per Million (ppm), Electrical Conductivity, Temperature, and Nutrient Dosages
-Room Conditions: Temperature (single readings or High/Low readings), Temperature Differential (DIF), Humidity (single readings or High/Low readings), CO2 (ppm), Plant Height
-Lighting settings
-Daily photos and notes




The GroLog also enables you to set a schedule and receive reminders for tasks you need to complete in the crop. Simply plan out your tasks and your device will alert you when it’s time to get to work, even if you aren’t in the GroLog app at the time.

Other features include:
-Customizable graphs
-Comprehensive reports that can be e-mailed or printed directly from the app
-Photo gallery

Note: Grodan neither obtains nor shares any information, data, or pictures entered in this application; all data is private to the user’s device.

What is Precision Growing?

If you are new to our industry and are wondering exactly what Precision Growing is all about then this post is aiming to help explain the process.

Precision Growing is the most efficient and effective form of growing, and is focused on the use of minimum input materials to generate maximum output. The results are that growing costs decrease and crop yield and quality increase. In addition, this form of growing actively contributes to sustainable horticulture.

At the National Precision Growing Centre we aim to encourage all growers to embrace the concept of Precision Growing via training and demonstrated best practice.

The Grodan company have produced a great new video to help explain the process so we hope that you will find this useful.

 Enjoy the video by clicking on the link below!

Helping to develop Hydroponic Growing in Mongolia.

Chisholm Institute, The Hydroponic Farmers Federation and Protected Cropping Australia have been working with representatives from Family Agricultural Resources Mongolia to look at developing a cropping systems that will allow Mongolian Growers to extend their natural growing season by 100%.

Due to the cold nature of the Mongolian climate, external growing is limited to approximately 100 days of the year. By establishing a hydroponic growing system within simple plastic growing structures and a heat source, it is anticipated that the growing season could be extended to 200 days, and help provide an ongoing food supply to many Mongolian communities.

This year saw two representatives from Mongolia, Turkhuu Yadmaa and Altankhuyag Ganbaatar, attend the PCA conference as a fact finding mission with the HFF paying for airfares and the PCA paying for registration to the conference.

Chisholm's Tony Bundock has also spent two days with Turkhuu and Altankhuyag, and the time was spent looking at possible working solutions for Mongolia as well as providing some basic training.

The project is one that will hopefully see Australian knowledge and technology being implemented in Mongolia. 

If you would like to become involved in this project and feel you can assist in any way, please e mail Tony at tony.bundock@chisholm.edu.au
