Visit to “Enrich” Composting Facility Co. Meath

Visited the Enrich Composting facility in Meath. The facility accepts Green waste from Landscaping and Council Brown bins from around the country. Material from Landscaping etc is chopped up and layed out in large windrows. The Nitrogen / Carbon balance is judged by eye and experience. The rows are turned each week to introduce oxygen and maintain the temp and breakdown process. It take just12 weeks to complete, the material is then sieved and blended depending on the application. The temp gets up to over 70 degrees, enough to kill seeds and pathogens such as e-coli. Steam can be seen rising from the rows.

The compost is sieved and larger bits put through the system again. They remove plastics etc from material entering the system but some smaller bits such as plant tags etc do get through.

A 20 tonne load cost 400 euro. 1 tonne bag approx 100 euro. The compost is not “Certified Organic” you make your choice I suppose!

How to make your own polytunnel

The first step is deciding where you want to possition the tunnel and how big you want to make it. The garden here runs North South with the house at the southern end. A line of tall conifers 35 feet high both shades and shelters the Western boundary. I decided to remove a line of hedging to make some room for the tunnel. Width was an issue and I did,nt have the space for a standard 10 foot wide tunnel.

After clearing the area I used the 3/4/5 pythagoras rule to set out the basis shape and using 10 mm reinforcing bar/string marked the footprint out as with any build.

Being over optomistic structurally I decided that it might be possible to span the 8 feet using 3/4 inch pipe. This was a mistake it’s much too flexible!. The rebar and 3/4 inch water pipe has come in handy since for protected covering etc as the re-bar fits perfectly into the pipe as does typical bamboo dims.

I needed to get stronger foundations and stronger piping and eventually went for the following setup. I got the piping in Chadwicks Sallynoggin Dublin . Ask for Shane Jordan ( helpfull guy). They have 60mm O/D  (outside dimension) Qualplast. You will need to bring along a bit of the piping you choose to the steel yard to be sure of a fit.I would not recommend the standard 48.3mm  scaffold as a cheap option as it is difficult to find a piping to sleeve over it comfortably without cutting or additional work.  I got the steel cut at a steel yard. It cost 70 euro to get 10 x 6 foot lenths of 43 mm galvanised steel tubing.Its 43 mm O/D and allows the plastic piping to fit over it easy. The weight of a person is enough to sleeve it into possition.

Once set out drive the 6 feet steel tubing into the ground to a depth of 3 feet using a sledge hammer, use a piece of timber to protect the pipe. The tubes are 4 feet apart.  For the 8 feet diameter I cut the plastic pipe 5.4m long giving a ridge height of 2.1 m plenty for the door and head height. In total I needed about 30 metres of plastic pipe at a cost of about 60 euro.

I did,nt want to use a trenching system so I designed a simple baserail.I got some 16 feet lengths of 20mm board and drilled through the board and into the steel tubing to fix this.

Using the base rail as a guide I drilled through the plastic pipe and steel pipe and bolted to secure. This acts as an anchor for the structure preventing uplift. To protect the baserail timbers I used a stabled on strip of D.P.C. and a paint on wood preservative.

The structure ended up being quite strong.

I used 2×1 batten to stiffen and some diagonals on the corners for lateral stability.

Above the diagonal bracings and a 100mm air gap. The soil/compost does not touch the base rail to prevent rotting. This way it is easier to replace rotten timbers in time.

Door detail

Top of door frame is secured to plastic tubing using 1 inch galvaband.

This is the basic structure before the covering went on. Its quite sturdy

Before the covering goes on its important to use anti-hot spot tape on the plastic pipes where the covering will touch. This prevents the covering from chemically reacting with the plastic pipe and becoming brittle thus prematurely needing replacement.

To secure the plastic covering I fixed lenths of of 2×1 to the baserail.

Then lengths of batten are used to secure the plastic. There is a method to attaching plastic to a tunnel. Start by getting tention above the doors on both ends. Then move to the centre on the sides and fix short lenths of batten tentioning as you go. This was the only part of the build that I need a second person to help. Work from the middle into the corners. Then start fixing around the doors and finish working the folds to the bottom of the doors.Its worth looking this in detail.

The plastic covering going on. Its best to do the work in the early summer on a warm dry and calm day as this help to get good tention on the plastic allowing it to stretch with the heat..The covering came from highbank, it’s 1000 guage plastic.

My wife Laura and I had quite a long day working on getting the plastic tentioned properly. We were very pleased with the result as was little Archie.

As I did,nt want to dig the ground I basically built raised beds inside, independant of the structure. I began by laying overlapping carboard boxes I got from a bike shop on the ground.

.

The rebar cut into short lenths came in handy to support the timbers of the raised bed. I filled them with a mix of rotten down farmyard manure, envirogrind, sieved and screened topsoil from elsewhere in the garden, some leaf mould and enrich compost.

Then the great pleasure of bringing in some plants from my smaller 6×8 foot greenhouse and planting out the tunnel.

I was,nt too worried about perrenial weeds etc on the paths as I reconed by making sure they received no water and got plenty walked on ,they would die off.

The tunnel was planted up in late July, here it is in August 2012. Not too many red tomatoes that year. In the background a geodesic duck enclosure under construction.

This is the tunnel before the pond went in and my neighbours trees got a haircut 2013.

This is the tunnel after further gardening projects in 2013.

Tunnel in spring 2013 planted up with rotation in mind.

The beautiful summer we have just had ment there was plenty of tunnel produce here I trained a cucumber along the roof.

Tomatoes underplanted with beetroot, Chillies and aubergines, courgette cucumber, , nasturtiams, and marigold

My advise to anyone thinking about getting a polytunnel is to have a go at making your own. You will learn lots by doing it. This is a relatively small tunnel suitable for a typical back garden, but the principals can be applied to much larger versions with the inclusion of intermediate timber supports. I know of a few people who have made these and they work fine in more exposed sites. The tunnel is over a year old now and while the garden is relatively sheltered it’s still doing very well. The tention is still like a drum.I did have a slight issue with the ducks and chickens pecking at the plastic near the baseboard. This may have had something to do with fact that they are attracted to red objects. I probably would,nt paint the next tunnel red. I would include a grill above the doors in a revised design to allow pollinators to gain easy access.MOST IMPORTANTLY there is an inside and outside to polythene. When standing inside the tunnel you should be able to read the writing on it by turning your head, if the writing is backward then turn this face to the outside otherwise you will have excessive condensation inside. On a larger tunnel I would definately include a generous potting and propagation area. Personally I have tried rigging up drip feed systems but as the space is small I quite enjoy hand watering and keeping a close eye on things.

Below is a small 6 x 8 feet demountable polythene covered greenhouse I designed and built. Completely different approach to creating protected cropping. This is where I start all my plants on shelves. It was built in sept 2011 and is doing well.

The basic construction is 2x 4 timbers built as frames and bolted together using treaded bar. Pipe insulation is cut open and used to protect the polythene from the timber. If I did this again I would use corrigated plastic sheets or glass possibly. There is plenty of room in it for growing food in raised beds. I have a vine growing in a pot to the rear trained inside the tunnel providing a little summer shade and some grapes. Its a lot of fun experimenting with different ideas in the garden.

Make a plan and stick with it !

Primetimes Organic Fact or Fiction Debate 05/11/13

To Quote Mike Gibney of U.C.D. Institute of Food and Health

 ” Organic agriculture uses pesticides, organic agriculture uses natural pesticides, its own pesticides and they kill insects so their toxic”

Clearly under pressure to say something off the cuff linking Organic and Pesticides in public perceptions.

 “To suggest that there is a danger with pesticides in conventional agriculture is what is getting Organic Agriculture into trouble, stop saying it”

Telling the other side what to do.

 A fairly dry debate, quite restrained overall ,nothing new. The first quote above is at 18.29 minutes in , watch the face on Darina Allen immediately afterward. Says it all.

Some Points:

Conventional agriculture does not want organic agriculture to be perceived as tasting better even if this is true, as its bad for business.

Conventional Agriculture does not want Organics saying it is a healthier option claiming their concern that this puts unfounded financial pressures on individuals with no health benefit.

I got the sense that the conventional side was allowed tell the Organic side what it should do, while the Organic Side rightly had no interest in telling the other what it should do. An Organic audience member (ha ha ) was baffled that the conventional side was not rowing in and embracing the opportunities presented with organics as it is a growth sector. Ireland is perceived as a green country internationally so perhaps we could make it one for real.

Why should conventional be allowed to clearly state that Organics are not tastier, that organics are not healthier, and expect Organics to accept this.

On the Conventional side science is used to justify its claims and those qualified to speak are therefore restricted to the academic realm. On the Organic Side Logic and common sense are the justifications for the methods used as well as nearly 10,000 years of pre industrial gardening. Importantly we are all to a greater or lesser degree logical and so we are all entitled to an opinion and voice in this conversation.

Organics should in my opinion be a minimum standard, with rising energy cost in time there will be no alternative as it is simply not possible to farm intensively as we currently do indefinitely, we don’t have the energy source (oil). What this means is that there will be lots more people involved with growing food locally. An lots more people buying local food supporting many more small growers and livelihoods.

As is happening , more and more people are supporting organic food producers and by doing so voting on how food production will be done into the future. Setting aside the health and taste argument for a moment buying Organic is a real way to support local small business and support families living within your community. For rural communities Organics provides a way to take better care of the soil , connect directly with people through markets and direct sale, add value and importantly be independent of the multiples who dictate the price and production methods.

To pass your local shop on the way to a multiple regardless of Organics or not is a vote against local small business. The 10% / 20% saving on price will likely be spent on fuel or can be balanced by the time saved in not travelling. I have heard it said that it is terrible how smaller towns and villages are losing their butchers and shops etc. Of course they cannot survive if we cannot get passed paying that little extra to support them. They will never be able to compete with the multiples but the point is maintaining communities and local livelihoods.

An organic chicken local to me cost 16.99 euro approx. Compared with a 5 euro chicken there is literally twice the meat on the bird so therefore it equates to 10 euro meat content in my book. There are even pockets of meet on the underside.  Of the remaining 7 euro price differential, I enjoy being able to support my local Organic shop and am happy to pay for it’s survival. I enjoy knowing the name of the lady who rears the chickens and that this is the price need to allow her to continue in the present context. I enjoy knowing that the chicken was cared for. I enjoy knowing the meat is the best quality possible, I enjoy the small scale nature of the business involved and can appreciate the effort in producing that chicken for that price. Instead of buying meat every day I just eat it less often.

Organic food presents a huge opportunity for new Livelihoods in Ireland. It’s important that those going in for Organics do so for the right reasons, that is to say with the understanding that this is a more sustainable way to produce food. For the multiples this may be seen as a fad that can make lots of money quickly . Organics is simply a method of food production better suited to being produced by the people for the people and a step in the right direction to long term systems stability. I’t no doubt scares the s**t out of some folk.

There are no boundaries to gardening. Nature is the master gardener so it’s good to get out and see what the autumn brings.
