Sorry if my info wasn't clear, I wouldn't boil it for five minutes but put in cup of boiled water and then drain.

I,ve had good success by collecting the seed in summer when ready, placing them in a cup of boiling water for 5-6 minutes to soften the seed coat and then sowing into trays. I have heard of the seed being direct sown after treatment though I,ve only ever grown in pots to be transplanted. When I do plant out I always put half a handfull of soil from a grown tagaste to innoculate the soil to enable the roots to begin nitrogen fixing. If you know where a mature tagaste is you can often find seedlings growing around that can be transplanted into pots or directly where you want them to grow.

Chamaecytisus palmensis or tree lucerne/tagaste is great for the chickens, its a heavy seeder, is evergreen and is a legume. It can self sow in warmer parts if thats a problem!

If it is available Acacia melanoxylon, common name Blackwood is a good option. Blackwood can tolerate wet feet and being a wattle is also a nitrogen fixer.

There is a farmer in Australia called Peter Andrews and he has developed a system called Natural Sequence Farming which looks at water movement through the landscape. if you were to google him or his system you may be able to find some ways to combat your salt problems. I am fairly sure this is the same farmer alluded to by rose macaskie.
