Raised beds sound like a great idea, that's how I've always done it unless i'm building a hugelbed (open the big hole, put in wood, then other organic matter, compost, manure, urine, etc, cover, let it rot down).
If you don't mind my asking, it doesn't look like you're really composting to benefit a garden, since the holes are under the grass. Is the goal to just avoid things going into the trash?
Tereza Okava wrote:Hi Arthur- those black patches look great, where you buried stuff. I think if you can do more volume you will get nice soil, regardless of moisture. I have helped build gardens in a few places with sandy soil (Florianopolis, Cananeia) and after a few years of doing this constantly the soil really looks different. While it will never be the same as non-sandy soil, organic matter will really improve things for you.
(your ovenbird is there probably looking for worms, or maybe to build his nest, I know right now they're stealing mud from my yard every time I turn around).
Some things will definitely take longer to decompose (I'm constantly finding pineapple heads, pinhão shells, skins from fruta do conde, avocados, etc, in my beds) so I wouldn't worry about it too much. If I were you I'd look for other sources of organic matter and make your holes bigger, if you are interested-- cardboard works, as mentioned earlier, I imagine your situation is similar to mine, we don't have too many deciduous trees in Brazil and so it's not just a question of getting bags of leaves or hay.... I personally use a lot of sugarcane pressings in my garden, along with coffee grinds I get from a local business and any other scraps I can find. I don't worry about salt, fat, meat, bones, etc-- some salt is no big deal, plants need it, and I think the only real worry is animals who might dig it up. You say urban, there are probably some kind of rodents (not sure how cold you get- maybe lizards? coatis?). One thing I do is when I have something that I think might attract the feral cats or rats into my yard (I am also urban) is to put a large rock, block or something heavy on the ground on top.
I think you have a good start! And I think that purple thing might be some kind of seaweed or beach detritus.
Waving hi from a few states up from you, in Paraná.
