Coco Coir Quandary

Coco Coir Quandary

Post  sfg4uKim on 4/19/2012, 11:03 am

OK so some of the research I've done says coir is suitable for replacing peat. Some says it's a replacement for perlite (I assume they would also say vermiculite). BUT the manufacturer (van der Knaap) says: Coco Crunch
may be used for up to 30% in peat mixtures to increase the air and
drainage capacity, horizontal distribution of water and quick drying of
the top of the container. It can be mixed excellently and can be an
ideal replacement for Perlite..

My questions is . . . IF IF IF IF IF I decided to use it - since it's supposed to replace some of the peat & vermiculite, will the following ratio work?:

6/24 peat
6/24 verm
3/24 coir (so as to not to replace too much peat)
9/24 compost

9/24 compost is a little more compost than the normal 1/3 (8/24) ratio in Mel's formula, but I don't see that as a bad thing.

OR should it be:
3/24 peat
3/24 verm
6/24 coir
9/24 compost

The reason I'm thinking of this ratio is that it's easier to measure in my 2.5 gallon buckets which I use to put the ingredients into my little cement mixer than if I did 5/24 each of peat, verm & coir. It would be (in 2.5 gallon buckets):

2 peat
2 verm
1 coir
3 compost

SOOOO I suck at math and would like you math geniuses to see if this makes any sense at all.

2 facts I've found about coco coir in my research that I'm still considering:

* it holds moisture better than peat
* BUT doesn't release calcium and magnesium particularly well



I have seen women looking at jewelry ads with a misty eye and one hand resting on the heart, and I only know what they're feeling because that's how I read the seed catalogs in January - Barbara Kingsolver - Animal, Vegetable, Miracle

The main reason that keeps me from buying coir in the US is the huge carbon footprint and the massive water waste that is produced in it's transportation and production.

I read that coir is not as acidic as peat so I wondered if that was good for nutrient release or not. Seems to me that we add peat, perlite, vermiculite, coir for similar reasons- they hold water and make an open airy soil. I like your last option, easy to do and splits the difference.
