Observe and make a
earthworks design for the entire site, with lots of rows of swales on contour.
Then I would try and increase the amount of
carbon in the soil
Biochar, woodchip,
straw - grass clipping, depressions filled with logs (inverted hugelkulture) and regular hugelkultures.
Next I would try to increase the soil life, manure/compost,
mushroom slurries,
I would them cover the site with 90% legumes (dutch clover, regular clover, alfalfa, etc,etc) I would also add adler it also fixes
alot of Nitrogen.
While the entire site is getting an upgrade, I would focus intensively on just 1 acre, planting out 180
trees (Fruit/nuts) at 15ft centers.
You can have a shallow swale infront of each 'row' of trees, that extend outside the '1-acre', have all of those extended swales funneling
water into the core 1acre.
I would also get 3 warre bee hive, with a once a year, start of season visit to split hives to restart the hive that died (odds are you will get a 33% death rate).
That is also time to harvest all 3 hives, after they have made it thru winter and nectar flow is coming from wild flowers and they need space.
I possible I would build a aquaponic
greenhouse, remove 4 trees to get a 15ft by 45ft
greenhouse.
I like the idea of grow bed(1), then walkway(A), then grow bed (2), then walkway(B), then grow bed(3). Each of them 3ft.
The grow beds are actually 3ft deep and wide swales that have a
pond liner then filled with water and fish, the excavated dirt is the walkway. And above the swales you have tables with grow media and vegetables.
I would also grow oyster and wine cap mushroom in the greenhouse area in hanging burlap 'towers'.
If you are going to visit weekly, You could try a super animal proof
chicken coop with a automatic feeder, then just come and harvest weekly (eggs+meat chicken+manure), and refill/check (water, battery, straw,
feed, baby chicks?)
So with vegetables,
honey, eggs,
chicken, fish, herbs, fruiting shrubs/canes harvest able the 1st 12months and with the nut+fruit trees in the ground with fruits possible in 2 to 4years, you would be looking good.
