["Antonio Scotti" <antonio.scotti@tiscali.es>]

Hello Darren, Mike,

many thanks for your pointers and info. I would not certainly mind sharing the resultus of the project ... if my design proposal

is approved.

 

My "problem" is quite tiny respect to the scale Darren has being woking with.

Basically I need to introduce a couple of sheeps, whose primary function should be as grass mowers.

Of course I'd like to have them perform more than that.

 

Darren suggested that shelter be under trees while Mike speaks about a raised building with a slotted floor,

I guess trees are a good option where climate is hot (?) like subtropics or tropics while perhaps in mediterranean climate (cold winters, though climate change might mitigate this pattern) -near the seaside, 1Km or 2- some sort of building would be better. Any opinions?

 

Milke I'd like to know more about the "zero grazing" system.

Also it would be great to have a look at some pictures of the building itself.

 

So my basic questions are:

1) how much space do I need to set apart for two sheeps to live comfortably, both as shelter and as grazing space.

2)What about the management strategy to keep them from spoiling the place?

3)What sort of rotation would you suggest?

4)How long should each sheep stay in their actual corral?

5)Do they mind sunlight or can they stay in a partially shady place?

6)The area where the sheeps are supposed to stay, now gives place spontaneously to a thick "weed" layer of clovers and lots of other plants.

7) Do they (2 sheeps I mean) produce enough milk so that cheese can be considered as a possible output for school-children workshops?

(They already make cheese but they need to buy cow's milk outside)

8) how to properly deal with their manure?

 

One of my ideas (not yet studied in depth) was to introduce some alley cropping

The place I am talking about has a couple of Ha available for vegetables growing, trees and ... the sheeps.

The design for the place is meant to optimize the activities that are already taking place there and possibly taking full

advantage of the potential of the place, which is at the time being, underdeveloped which in turn means that this place needs (in my opinion)

ways of getting at some form of self sufficiency both for educational purposes (showing school-children what sustainability means in a periurban farmyard

environment,  very close to where they live infact) and for economical purposes.

The place also hosts an anphibian pond project, a butterfly observation project and a bird watching project.

So I need to integrate the sheeps in this context.

 

The water resources are quite good, there is plenty of water all year round coming out of a water mine. This water is not classified as drinkable for humans but I guess people living in the farm in the past has always drank it.

Hello Antonio,

 

My bread and butter is (re) designing mixed sheep and cropping farms in South Eastern Australia - however on a broadacre basis - the same principles apply for you only on a broader scale. Naturally you’ll have to start with a plan/design – the following concepts and physical elements could be included in such a system.  

 

Soils:

Getting the soil sorted out is the first step as in any agricultural system there is (or has been) net nutrient (soil capital) loss over time causing an array of symptomatic responses eg. Weed incidence, soil acidity, soil structural decline, erosion, animal/plant health issues etc. Naturally as the permaculture retrofit of these systems develops there will be (through design) less nutrient loss and annualized improvement of the system overall.

 

We follow the Albrecht method (www.apal.com.au) which through specific soil testing recommends feeding the soil not the plant with a range of organic and non-organic fertilizers and amendments respectively. The method initially focuses on correcting the imbalances of the Base Cations i.e. Calcium, Magnesium, Sodium, Potassium, Sodium and Hydrogen. Achieving numerically based balance of these creates the soil structural conditions appropriate for the maintenance of more sustainable agricultural systems (chemistry effecting the physics promoting biological systems). Neal Kinsey’s book “Hands On Agronomy” is the modern classic on the subject and makes the whole Albrecht method very easily understood. Using this method (as we have on hundreds of properties over the last 6 or so years) you will use less fertilizer, more consistent yields, radical soil improvement, and improve stock and plant health.

 

Also look at progressive cultivation using a keyline plow (www.yeomansplows.com.au) or similar non-inversion rigid tyned implement to reduce soil compaction and improve run-off entry and increase soil depth.

 

Food:

Grazing of mixed species pastures with high proportion of grasses and legumes (mostly rye grass (perennial and annual), fescues, cocksfoot and bromes with clovers and medics - including Lucerne - also "tonic herbs" @ about 2-3% of sowing: plantain, chicory, dandelion, garlic, yarrow, comfrey and borage. Cell grazing using portable electric fencing allows "pulse" grazing of pastures down to 2 - 4" then move the mob into the next strip. This rests the grazed strip and allows you to manage the pastures better and establish high productivity gains. If you can do this on contour/keyline then even better. Maintaining 100% ground cover is essential to sustainable production and erosion incidence. Also favour species that are don’t have spiky seed heads as this can cause eye and nose problems.

Browsing of deep rooted fodder trees which are either established in blocks or as hedges along gully edges or as subdivisional fencing. Species and layouts vary but should consider land class and land form - best layout is "keyline alleys" in my opinion. That is tree belts that follow keyline contours and are accordingly integrated with the overarching farm layout. I would break fodder trees up into three categories (following species are suited to temperate/Mediterranean regions – local analogues for other climates should be included):

 

1.    Quick growing shrubs: Cytisus palmensis (tagasaste), Atriplex nummularia (old man salt bush), Atriplex amnicola (river salt bush), Acacia saligna (coastal wattle) + local analogues. These species are classically placed along fence edges or are planted as blocks as monocultures with pasture or as mixed species layouts (latter preferred). Fodder is in form of direct leaf browse. “Living Haystacks”.

2.    Pollarded Trees: Populus spp (poplars) and Salix (willows). Grown again along edges, in rows or as blocks. Essentially a system of coppice fodder production – fast growing high production (8 - 20 tonnes/ha wet matter in China from Populus systems) high nutrient/protein leaf and stem fodder.

3.    Larger trees: Ceratonia siliqua (carob), Gleditsia triancanthos (honey locust), Morus nigra (mulberry), Quercus ilex, suber, microcarpa, virginiana (low tannin oaks). In North America Proposis spp (Mesquites) could also be utilised (severe weed here and in Africa though). Planted as “paddock” trees on own (@10m – 20m spacing) or in rows (linear or keyline layouts) or as blocks. Fodder as lower level leaf browse but mainly as pod, fruit or acorn fodder. This produce can be harvested for storage (not mulberries except in jam for us!!) or directly as respective fruits fall to ground and are eaten accordingly. Typically high yield carbohydrate rich end of summer feed. As such perfectly balanced with protein feeds such as leaf fodders.

 

Water:

 

Good clean water supply is essential to maintaining good stock health and to reducing pathogen and parasite transfer. Remove stock access to any open bodies of water and establish a reticulated system (preferably gravity) of stock watering. Closing stock access and revegetating dams and creeks etc. will improve the water/environmental quality of these systems – which if being used as a source of stock water is a means to an end – not a source of infection! Draw (pump/windmill etc.)/Divert(pipe) water from high quality source to high level tank/storage – then reticulate to a network of stock water troughs throughout the system.  

 

Shelter:

 

Establishment of tree fodder systems such a way that you increase shelter should be a primary aim of the design process. “Each element performs many functions”……… The principle of shelter effects most worth noting are: that shelter protection effects are around 10-15 times tree height (lee side of shelter) and that the degree (or coefficient) of protection is a function of shelterbelt layout and porosity. That is to say that if a shelterbelt is too dense then it will create turbulence and have a reduced shelter impact – 20-40% shelter porosity “absorbs” then wind and increases the respective shelter protection. If you have a succession of shelterbelts (contour strip forests or alley farming) then a net reduction of ground wind speed will be afforded to the system.

 

 

 

I hope all of this answers some of the questions you may have.

 

Baaaah!

 

Cheers,

 

Yours and Growing,

Subject: [permaculture] Sheeps management

 

Hi all,

I was asked to consider introducing a couple of sheeps in a design I am

making for a Nature School, eg a local administration run place where school

children are brought to in order to learn about environmental matters and

nature.

I am looking for advice on sheeps managament in a permaculture system.

Web pages, publications, your own advice ... since I know nothing about

it.

The books that I have hardly mention sheeps management (Permaculture 1,

2, Introduction to PC) I am not sure about th Designer's Manual since there

is not a specific entry in its index.

Any help would be appreciated

Thanks in advance,

Antonio
