Hi, I need some help with making a soil, I'm no newb to growing organically, I've made alot of mixes in the past, but most of them were experimental flops, and I'm still not sure what makes a good soil good to be honest
The ingredients I have right now are : horse manure worm castings(weighs 350g per litre), grow green organics kraalmis(cow manure/sawdust humus, weighs 400g per litre) most of their batches are quite undecomposed but I got lucky and scored a couple bags of pure humus, grow green organics mushroom compost (basically just partially decomposed bark, very acidic), coco coir, dark loamy clay garden soil and golden wattle leaf mold, I also have access to culltera herb mix, wormbosch castings and perlite but I'd like to avoid those because even though i know how good they are I don't feel it's worth the price, my local nursery over charges for them.
For amendments I have: bloody bone meal(5-10-0), dolomite lime (10% mg-16% ca, Epsom salts, gypsum, talborne 5-1-5, protek guano pellets (2-3-2) it's poultry manure not guano, bioocean poultry manure pellets with kelp and fishmeal(3-2-3 and high in iron), all season poultry manure pellets(4-1-3), superphosphate(0-5-0) it's not as bad as most people say, it's basically just calcium phosphate(same compound as in bonemeal and plants) and gypsum, then a bale of lucernce for mulch
The recipe I have in mind for seedlings and vegatative stage is 10% kraalmis, 10% mushroom compost, 25% horse manure worm castings, 5% leaf mold, 5% garden soil, 45% coco with 100 g all season pellets, 50g guano pellets, 20g dolomite and 20g superphosphate for 10l, it's close to a recipe I've used before but with more castings, less mushroom compost, less lime and without Epsom salts, the other recipe also didnt have garden soil or leaf mold, both of which I'm using as a microbial innoculant and replacement for rock dust
To make up for the lack of perlite I just make sure my soil is fluffed up and is holding the most water it can without being too wet or heavy when it goes into the pots, then water gently until a hard layer forms on surface to prevent compaction
All my plants go from 1l to 10l pots and then into the ground, I'll probably do another post asking for some advice amending my garden soil in the near future, sorry if this post is too long, just wanted to give the maximum amount of info for the best feedback, please criticize my mix, should I ditch the superphosphate and dolomite then replace with bonemeal? Should I maybe not use wattle for leaf mold? Is there ANYTHING anyone would do different?
