Here we go guys , How I build my soil . So I start with 260 ltr of mid range bag soil as a cost of $140 Au dollars from local hard whare store . That is my base soil , then I lay it out on a tarp in a line , to this I add powdered Indonesian Sea Bird Guano which I use a coffee grinder to powder and has a good amount of calcium in it , Langbeinite - this time I cut right back on it as it way to expensive to use , and I like my liquid sea weed better due to the extra it has to offer and I don't water to run off or very little nutrients a held longer ---- Just on a side note , I see a lot of guys have problems watering and not understanding amounts to use and I would say a lot of there problems incur due to to much run off , I have seen posted lately a number of post about it and as what has been stated and very important [ learn to feel the weight of the pot ] it would help them a lot --- back to soil , Now I have my base soil down , to this I add 80 ltr of left over soil from the last batch which has been looked after - moisture and feed wise Molasses . lastly I add 60 ltr of compost Which I get off a friend of mine , Too lazy to make my own and his is great being a organic farmer and if is free ,
In the first photo you will see the Langbeinite 1 cup which is very little for the amount of soil and to the right a little bottle , the lid has holes in it to shake it out , I use whole pot full .
now that I have added it to the top of the soil
To this the compost is added
Next I get one of my sons to give me a hand , Being a big tarp we grab a conner each and walk toward the other in and repeat that about 6 times so it is all blended in well
Being so much I did it 1/2 a batch at a time .
Now the good bit , adding the fish , It has been done in 4 layers . How much , just over 10 kg or there abouts , Adding fish is one of those things you have to learn your self . The plants will tell you if to little or to much , Get if right and you don't have to worry about nitrogen , as a guide it has a NPK of 4.1.1
No I top it up with the rest of the soil . the make up 15 ltr of with molasses and liquid seaweed added . I also add in what worms I have which is not enough as it is the dry season and hard to find , but is not a problem as the wet season is just around the conner , then I will have heaps , I only like to use worms from the ground as they travel deeper in the soil . Up to 6 feet so it is not a problem having a large amount in a tub [ lots of holes in the bottom ] Some might say , what about the fish smell . there is none , just make sure you have at least 30 cm or 1 foot of soil on top
you have to do this , cover the soil , I use thick black plastic and the top of the tube has a cover as well [ Roofing iron ] Keep a eye on moisture level , do not have it to wet , also feed the microbes , molasses is great , I also add liquid sea weed now and again . The water I use is fish pond water and I always get a soil Ph of 7 . Another thing to remember is leave it for a least 3 months being cold composting and the first 2 months turn it 3 or 4 times another value of earth worms is they go from top to bottom of the tube which brings in oxygen in to all layers of the pile . If done right the soil has a very nice smell to it and when used for your grows it is a very easy way to grow and I agree with
@WildBill this is organic growing .
