This is a gadget which should exist, but I haven't seen it yet.
Suppose you want to water a large area of ground which you have just
sown, and add some liquid fertiliser at the same time. The area is too
large for a watering can, or even a portable spray if you are going to
do it properly. You just want to use a hose. So it would be handy
to be able to screw on a spray attachment which would release small
quantities of minerals and other nutrients in the recomended dilution,
ie in proportion to the water-flow.

Any offers?
