Peat Potting Mixes

 While doing some research I came across this article about compost being used instead of peat.

"Benefits from using

compost in potting mixes

The increasing price of peat in many

countries in the late 1980’s resulted

in the widespread use of recycled

organic materials as a substitute for

peat in potting mixes.

Composts are an effective substitute

for peat because the organic fraction:

• absorbs and releases water;

• slowly releases nutrients;

• assists in nutrient retention; and"

• suppresses the growth of plant"

Sheep poo and potting mixes

I've been mixing a fair bit of sheep poo into my hot berkley style composts for some time now with good results.

There is a great US no dig classic book in the GOG library where he tried all sorts of vegie growing experiments and got best resulats by planting early and potting on seedlings into 3 to 6 inch pots depnding on type and using parcel packaging style little polysturene balls in the mix to keep it really open and light.

I think the sheep poo does a similar thing but is way more organic / sustainable.
