"Accessible education in Organic Land Care." In my opinion, you will learn more in even their shortest courses than you would studying horticulture in college or university. Actually, it's not just my opinion, because post-secondary grads have taken the courses and said that. I now teach some of their courses, but several years before I started teaching, I took a course and it was a life-changing experience.

Hundreds of classic books online for free (they ask for an optional one-time donation of about $15, which is well worth it).

This link leads you to a bunch of great articles, but it's also the place to pick up most of the best books, cds, and their magazine on sustainable horticulture.
Okay, I now have a few links for soil testing instead of just one. I have generally used International Ag Labs, but I came across some others that are also good. Below are a few of the labs doing the kind of tests that I believe are most useful, based on the ideas of Albrecht and Reams. They're generally in the US, but it's worth shipping there. It generally costs around $50, plus about $20 to ship.
International Ag Labs - Mainly following Reams, but they also do CEC (run by Dan Skow, co-author of Mainline Farming for Century 21). Note, effective March 1st, 2013, this lab will no longer accept soil samples from outside the US. The two labs listed below still do, though:
Crop Services International - Albrecht and Reams and other energetic philosophies (run by Phil Wheeler, co-author of The Non-Toxic Farming Handbook)
Kinsey's Agricultural Services - Mainly following Albrecht (run by Neil Kinsey, co-author of Hands-On Agronomy)
Soil Food Web Canada - In Alberta, they've recently started doing soil chemistry testing that looks decent, but the exciting part is that they also do microbiology testing for soil, compost, compost tea, and even leaf surfaces. I took their three-day introductory soil biology course in November 2010 and found it really informative and worth while.
Cultivating Soil Solutions - Kathleen Millar offers educational opportunities (some in cooperation with Gaia College) and consultations, as well as local compost, compost tea brewers, and regionally acclimatized seeds in the Central Vancouver Island area. She is a certified Soil Food Web advisor and conducts soil biology tests using her own microscope.

Liquid Kelp Fertilizer Resources
Good summary of various research
Study on liquid kelp foliar applications (pdf)
http://www.springerlink.com
This article was free when I initially looked at it, but now it seems to be for sale.
Summary: "The plant growth, developmental and N nutritional responses in this greenhouse experiment have demonstrated the effectiveness of two kelp, M. integrifolia and E. maxima, foliar sprays as plant growth regulating substances."
Also interesting: "Low dilution ratios (1:100 kelp concentrate:water) were found to have an inhibitory effect upon root growth, whereas higher dilution ratios (1:400 to 1:600) were stimulatory." This (and other parts of the study) shows that following the product directions and using the seemingly small amount of kelp:water is better than applying less diluted mixtures (less water). The same holds true for other products. More is not better.
Study on kelp soil applications (pdf)
http://www.springerlink.com
This article was free when I initially looked at it, but now it seems to be for sale.
Summary: Applications of kelp up to 60 tons per hectare (1/2 ton per 1000 sq ft) increased plant growth, but 120 tons inhibited plant growth, probably due to excess salt. I'm not sure what 1/2 ton per 1000 sq ft translates to in yards, but it looks like you can apply too much kelp for certain crops.

Blackstrap Molasses Resources
Molasses as microbial stimulant (and ant control?)
http://www.malcolmbeck.com
One container was given only tap water; the other was given equal water with two tablespoons of molasses per gallon stirred in. After 8 weeks, the molasses watered plants were almost twice the size of the plants in the other container.
...I dissolved 4 tablespoons of molasses in each gallon of water and sprayed along the drip pipe. By the next day, the fire ants had moved out four feet in each direction. We were able to graft the vines without a single ant bothering us.
Molasses and whey mixture cleans contaminated soils
http://sanjose.bizjournals.com
This company injected cheese whey, then molasses and then a mixture of both into the ground, finding the right ratios through trial and error. Supplied with a plentiful and evidently ideal source of food, the bacteria multiplied. As time went on, however, the cheese whey and molasses ran out, leaving a now-expanded population of microbes in search of something else to eat. While solvents and the other pollutants are not the food of choice, the microbes will eat them. "We have had contaminant concentrations that have decreased 99 percent or more over the last year with the cheese-whey solution."
Molasses helps control pathogenic nematodes (pdf)
http://www.aftresearch.org
In a papaya plantation on Maui where high and damaging populations of reniform nematodes had caused a reduction in fruit yield and quality, the molasses applications lowered nematode soil populations and resulted in marked improvement in the tree growth and harvestable fruit. When applied to Chinese cabbage, the numbers of Herodera nematode cysts decreased following harvest. Preplant applications of molasses to onions improved plant color and onion yield although no difference in soil nematode populations or in cyst number was observed.
