Hi,

I have just had my garden landscaped (removing a massive terrace full of
rubble), however its now down to faintly yellow looking clay, all the
black soil on top has gone. It reminds me of the stuff I used at school
to make pots out of!

Having read about how to improve the soil to make it suitable for
lawn/veg/flowers, the answer appears to be I need to add a lot of
organic matter to it, and not work it when wet! (?)

I am new to gardening, and am now confused about the various types of
compost available, and what is best to use;

Organic Compost (Screened to 10mm/20mm)
"Compost"
Soil Conditioner
Well Rotted Farm Yard Manure
Various ground up bark/wood products some of which seem to be marketed
as peat replacement.

Any help and advice would be appreciated.

Your garden soil shouldn't be more than 5% organic material.

Garden soil should be 30% - 40% sand, 30% - 40% silt, and 20% - 30%
clay. You can check your soil by scraping away the organic material on
top of the ground and then take a vertical sample of your soil to 12 in.
(30 cm) deep (rectangular or circular hole). Mix this with water in an
appropriately large glass (transparent) jar. The sand will settle out
quickly, the silt in a couple of hours, and the clay within a day. The
depth of the layer in relationship to the total (layer/total = % of
composition) is the percent that fraction has in the soil.

Garden soil needs a constant input of nutrients, i.e. carbon, e.g. brown
leaves, and nitrogen, e.g. manure in a ratio of C/N of 25. This is the
same ratio you will what in a compost pile.

A Balancing Act (Carbon-to-Nitrogen Ratios)


All organic matter is made up of substantial amounts of carbon (C)
combined with lesser amounts of nitrogen (N). The balance of these two
elements in an organism is called the carbon-to-nitrogen ratio (C:N
ratio). For best performance, the compost pile, or more to the point the
composting microorganisms, require the correct proportion of carbon for
energy and nitrogen for protein production. Scientists (yes, there are
compost scientists) have determined that the fastest way to produce
fertile, sweet-smelling compost is to maintain a C:N ratio somewhere
around 25 to 30 parts carbon to 1 part nitrogen, or 25-30:1. If the C:N
ratio is too high (excess carbon), decomposition slows down. If the C:N
ratio is too low (excess nitrogen) you will end up with a stinky pile.

No reason to till after the first preparation of the garden (no reason
to till the first/last time but it does speed up soil development).
Spread out your soil amendments:
€ N:
€ 18.37 lb. chicken manure/ 100 sq.ft. (2.88 oz/sq.ft.)

€ P:
€ 3 lb. / 100/sq.ft. (.48 oz/sq.ft.)

€ K:
€ How much wood ash should you use in your garden? The late Bernard
G. Wesenberg, a former Washington State University Extension
horticulturist, recommended using one gallon of ashes per square
yard on loam to clay-loam soil, and half as much on sandier soils.

Cover this with newspaper (to block light from weeds and provide a
barrier to sprouting weeds). Cover the newspaper with mulch (up to 6" in
depth). Spray the garden bed with water, and wait 6 weeks before
planting (if you can).

A dibble can help with planting. The dinky little ones from the nursery
may be of some help, but I prefer a sharpened, old, shovel handle for
making a hole through the mulch and paper for planting seedlings.

Adding drip lines takes a little time, but saves a lot of time during
the season.

That's all I know.


Seems I was correct... a lorry load IS the same as a shit load... and
here you just got a major lorry load of billy goat shit! LOL-LOL
