We’re in the middle of two solid weeks with no sun!! Just when we’re all geared up to get stuck right in we have to stop, at least in the garden beds.
My fish fert is brewing away, my CalPhos is also bubbling away, the dried ground eggshells, cow manure, molasses and seaweed is smelling good.
I’m going to add to my list of possible soil amendments by making a few netting rounds to pile up with leaves, and leaving them to turn to leaf mould .. next season I’ll collect the leaves in Autumn rather than Spring but we still have leaves under our oaks so better late than never. Making leaf mould from the leaves of trees that accumulate the key minerals we are needing to create the balance our soil needs in order to grow nutrient dense food, will be a way that is possible even for those of you in the city. There are so many parks where trees drop leaves and many contractors sucking them up to take away, it might be possible to ask them if they could dump them in your leaf mould factory. Leaf mould is great for mulching berry beds, perennial beds, putting in the bottom of your potato trenches, mulching crops that will soon cover the bed e.g pumpkins, tomatoes, peppers and eggplants. Also great for mulching in the forest garden. My goal is to have enough linden leaves (tilia spp also known as Lime trees, and amazing bee forage) to make enough leaf mould each year to use under potatoes, tomatoes and to mulch all berry beds and perennial beds because it accumulates both Calcium and phosphate. That means we end up with humus containing high levels of both calcium and phosphate, just what we are looking for. Linden leaves will also be great in the chicken scratch area to be turned to compost by the chickens along with our oak and maple leaves (refer to chart of mineral accumulators for more details).
We’re setting up our worm farms and soldier fly farm, this week in the new greenhouse, using just the same design and process that we used for the Koanga Urban Garden Project. As in the Urban Garden they will produce vermicast and soldier fly liquid to use in the garden as well as charged bonechar from under the solider fly larvae….
Review of Strategies
So to review our complete list of strategies for maintaining and building soil fertility in local and simple ways.. this is it for this Summer growing season:
- Compost, made following instructions in the Koanga Art of Composting Booklet, with key feature being 60:1 carbon :nitrogen ratio which means 1 part immature material, ½ part soil 3 parts mature material, plus the addition of key ingredients designed to raise minerals level sin a balanced way, and encourage the creation of humus e.g seaweed, biochar, clay (we have pumice soils) pottery shards (increase magnetism levels), lots of calcium sources.. oak leaves, burnt shells and bones, lime, lots of phosphate containing ingredients.. eg oats, lupins, linden leaves, cassurina leaves, crushed eggshells and bone char. Our goal here is to produce maximum amounts of humus charged with nutrients. We are achieving 30% in our best heaps and to increase the cation exchange capacity ability of the soil to hold moisture, minerals and microbes. Our goal here is also to recycle our humanure, blocking a major leak out of the system
- CalPhos – used to strengthen plant cell structure and to prepare the plants to set and grow fruit
- Fish Fertiliser – to feed the microbes and boost with nitrogen
- Kay’s Fertiliser – a basic homemade balanced microbe and plant food
- Leaf Mould addition of fungi, and humus charged with minerals
- Urine charged biochar…. Increasing cation exchange capacity, creating more stable moisture levels and holding minerals
- High in humates, great for nutrient boost or making seed raising mix
- Occassional uses of cow manure and molasses
My over arching goal is to be able to grow brix 25 veges using compost only…
