You don't mention what kind of soil you have? Sandy? Clay? Whatever type you have, you need to get your soil in balance.
The first step is to learn how to make your own Aerated
Compost Tea to apply to your soil in conjunction with using protein meals for fertilizer/critter food.
Having healthy soil means you have the right biology that keeps your soil from become compacted, drains well, and then you can reduce the amount of inputs required. When the soil foodweb is in balance, you can reduce the amount of watering dramatically as well as your need for other inputs.
There will be an initial expense to purchase a compost tea brewer and protein meals for the first year. But as time goes on and your soil gets in balance, inputs are reduced.
I highly recommend the tea brewer by KIS. Here is their link:
http://www.simplici-tea.com/ I use their 5 gallon brewer that works great for more properties up to an acre in size. However, I use Alaska humus instead of compost as it is a 'step up' from compost and worm castings. I purchase ingredients from Alaska Bountea. Here is their web site:
http://www.alaskabountea.com/ Their brewer system doesn't work that well, but their ingredients are some of the best available.
Another source for Alaska humus is the Alaska Humus Company. Here is their link:
http://alaskahumus.com/ You will need to get up to speed on the whole process of creating a healthy soil biology. The SoilFood Web is the best source of everything you need to know about making Aerated Compost Tea. Here is their link:
