Garden beds and compost tea

Yesterday we laid our first garden at school...
We made a compost tea with:

1 cup of compost
1 cup of KOR compost
1/2 cup of worm casting
2 tbsp molasses
2 caps seasol
2 caps liquid humus (NTS)

put ingredients in a shadecloth bag, then dunk like a teabag in 4 buckets of water.

To garden bed, add
Dolamite
Gypsum
Agricultural Lime
mineral rocks, cracker dust

we laid the light materials first, so we could see the layers as we added the next ingredients on the bed.
After the composts, we used a fork to till the soil, lowering the tines in then using the wooden part of the fork to lever the soil up to aerate it, careful not to disturb the layers of nutrients we'd added.
After aerating the soil, we used the flat edge of a garden rake to smooth out lumps. Then we lay wet newspaper, a couple of layers thick over the whole surface of the bed, tucked into the edges to stop weeds coming through.
Then we laid thick straw to the point where there was no newspaper visible through the straw. After the straw was levelled out, we hosed it to dampen it in.
Then we constructed a tripod out of bamboo to act as a climbing surface for beans. Around each leg of the tripod, we planted 4 beans. The rough edges of the bamboo where the leaves shoot from were left on the tripod to give the beans something to cling to.
After planting the beans, we planted three globe artichoke seedlings in the centre row of the bed, to provide some shade. Then closer to the edge of the bed we planted broccoli seedlings a butterfly handspan apart, all the way along. Around each of the broccoli seedlings we planted onion seedlings, around 5, in a scalloping row to the left of the broccoli then semi circling behind and around it then onwards to the next broccoli. 
On the other side of the globe artichokes, towards the middle of the bed, we planted beetroot seedlings in a zig zag fashion.
Along the edge where the onions were planted, we also planted turnips and lettuce.
In the centre between the artichokes, we planted petunias to attract the right kinds of insects and also because they're edible.
