Cider # 4 - Prototype Orchard

Not strictly cider related but on the subject of fruit trees anyway.  I'm in the process of clearing an area against the South face of the hay barn to create a mini fruit plot.  If I paint the wall white I thought it would hopefully create a warm, sunny and neat-looking spot to experiment with fruit trees.  The barn is 24 ft long, and the rubbish-filled area which I'm clearing extends about 10 ft out from the barn, giving 240sq.ft of potential growing space.

The Site!
In order to clear the site I've been clearing some steel A-Frames from a long-forgotten project, partially completed and for the last 10 years or so slowly becoming part of nature again.  Its mostly been a case of angle-grinding them into wheel-barrowable sections (say 100kg) and then Polo'ing them to the scrap yard.

Taking down the A-Frame on the left of the picture above was an interesting experience.  It was attached to the main frame of the barn by two U-bolts which are normally used to hold leaf-springs onto commercial vehicle axles.  On the other end the frame was literally balanced (not attached in any way) onto a steel upright which, not having been placed correctly in the first place, had been extended with a flat plate bolted to the top.

"Old Tymawr" Engineering!
I'm quite glad that I never had a picnic underneath it!

Anyway, after angle-grinding the lower U-bolt through and leaving the frame supported by the top U-bolt and the flate plate above, I knocked the frame off the plate with a sledge hammer, leaving the whole frame (250kg) pivoting off the top U-bolt.

A final angle-grind through the top U-bolt dropped the whole frame fairly neatly onto the ground.

I've been reading Sepp Holzers's "Permaculture" http://www.amazon.co.uk/Sepp-Holzers-Permaculture-1-Holzer/dp/1856230597/ref=sr_1_1?ie=UTF8&qid=1358629337&sr=8-1.  He has some really interesting techniques for fruit tree growing which I'll try to emulate here.  Main points are:

1. Grow green-manure crops around the base of the trees before and after planting.  Grass is too strong a competitor for the shallow part of a fruit-tree root system (see also http://www.amazon.co.uk/Agricultural-Testament-Sir-Albert-Howard/dp/8185569185/ref=sr_1_1?s=books&ie=UTF8&qid=1358629637&sr=1-1 for a full explanation of this phenomenon).
2. Place large rocks around the planting area to absorb and slowly radiate heat.  These have the added benefit of encouraging worms to congregate underneath them.
3. Use pigs to turn over, plough in the green manure and add their own manure to the area prior to planting.
4. Use pomace left over from cider making to seed the area to produce root-stocks for subsequent grafting (a good idea I had which might improve this further would be to feed the pigs the pomace and let them manure and seed the area simultaneously!).

If possible I'd like to grow soft-fruit bushes around the fruit trees and amongst the green manure crops (peas? beans? mustard?) to maximise the use of the space.  Finally, we've got plenty of mistletoe around the farm at the moment, it would be great to deliberately encourage it into the fruit trees too.


So, once we're cleared up I think I'll put the chickens on that area to scratch it up, then spread compost and sow some green manure.  This will start the slow process of preparing the area for tree-planting this time next year.

Chickens # 11 - Laying Data

We have two mini-flocks: The Old Flock, consisting of 6 Light Sussex Hybrids which we bought in May 2011, and The New Flock, consisting of 6 Light Sussex Hybrids bought in September 2012, cohabiting with 1 random brown layer and 1 tiny all-black cockerel, both of which arrived a fortnight ago when a lady arrived at the door with them in a pet-cage asking if we would 'take them in'.   Never look a gift chicken in the mouth I say!

The Old Flock, after a hugely productive first 18 months or so with us, moulted this year in November and more or less stopped laying (well, 1 per day between the 6 of them) for nearly two months.  The New Flock arrived with us as 'point of lay' pullets at 16 weeks old and started to lay erratically at about 20 weeks, but have now (at 34 weeks) settled down to the 'usual' super productive cycle.

I'm planning a chapter in The Book covering some useful maths, statistics and analytical techniques which will hopefully be of great benefit to Farm business leaders.  I don't have enough data for the first 'worked example' yet, but here's a quick preview:

    New Old Brown
  No. Hens 6 6 1
  Age in Weeks at start 34 102 ?
06.01.2013 Sunday 6 4 0
07.01.2013 Monday 6 4 1

09.01.2013 Wednesday 6 6 0

11.01.2013 Friday 6 6 0
12.01.2013 Saturday 6 4 1
13.01.2013 Sunday 5 5 1
14.01.2013 Monday 5 6 1
         
  Mean 5.44 4.56 0.67
  Median 6.00 4.00 1.00
  Mode 6.00 4.00 1.00
         
  Laying Efficiency 90.74% 75.93% 66.67%

Laying efficiency is the mean divided by one egg per day per day per hen which I think is a simple, easy metric (not strictly accurate but useful nonetheless).

I'll update the data over the coming weeks and when I've got 30 data points per flock I'll do some analysis.
