I've been able to follow, and participate to a degree, in Mr. Solomon's metamorphosis from expert "organic" gardener to expert "nutrient dense" gardener. Solomon, in my opinion, has long been ahead of the pack as evidenced by his books "Growing Vegetables West of the Cascades" and "Gardening When It Counts." Through his early gardening experiences and from starting the Territorial Seed business he devised his Complete Organic Fertilizer (COF) which was an attempt to balance garden soil. COF is still a good way to go for people who don't wish to go any farther and the formula is easily found on the internet. (Also in The Intelligent Gardener pps. 84-85).
In the last half dozen years through association with Michael Astera's Nutrient Dense Project and a re-study of the work of scientists like William Albrecht and Victor Tiedjens, Steve Solomon has become a convert to the concept of "nutrient dense."
The concept of nutrient dense food is pretty simple. The gardener works over time to balance the soil with the proper mix of minerals. The result will be soil that encourages the life forms (worms, bacteria, etc.) that help with soil symbiosis and soil that provides the nutrients plants need to grow properly. Balanced soil will mean healthier plants, resistant to pests. Balanced soil will result in food that is nutrient dense, providing us with the vitamins and minerals we need to be healthy.
Steve Solomon spends a lot of time debunking the concept promoted by J.I. Rodale that compost would solve all problems and that by continuing to heap organic matter on a garden a garden would only get better and better. This is not the case as Solomon explains in detail in a chapter titled: SAMOA (The S*** Method of Agriculture). More important is bringing calcium and magnesium into proper balance. When garden soil is properly balanced, according to Solomon, the garden will create its own nitrates.
Balancing calcium, magnesium, potassium, sulphur, sodium and other minerals is the key to nutrient dense food. Getting this balance correct begins with a $20 soil test. Then, with a copy of The Intelligent Gardener in hand, one can use the worksheets provided to come up with a prescription for a custom fertilizer designed for one's own garden. Solomon's colleague and co-author, California gardener Erica Reinheimer has developed a website where you can find copies of the worksheets found in Steve's book. On this same website you will find a link to "OrganiCalc" which allows you, for a small fee, to compute your custom fertilizer prescription on line.
After a quick initial reading of the book, I am optimistic that I will be able to balance my minerals and improve tilth in the process, by one of several options described. I should be able to calculate it myself after a particular soil test, without a degree in chemistry and higher math, or I can take an easier route and submit a sample to a lab, then get an online interpretation of what is needed--for a total of about $30. There is even a recipe for a "best guess" fertilizer, based on what most vegetables might need, for those who only have a few plants and can't afford to test.
The most important point I have learned so far is that balancing the minerals in the soil can boost the micro-life, improve the holding capacity of moisture and nutrients and provide food for maximum nutritional value and taste.
You can get recommendations for best local varieties and planting dates from a local extension service, but this book provides home gardeners with much information that was not readily available earlier.
If I could give half-stars, I'd give this 3.5. The information is useful (albeit really dense in places...but we're talking about soil amendment recipes here, so, you know) but it's not entirely practical especially if you're low on capital at the outset. What specifically was useful? Solomon's basic argument is that plants contain nutrients derived from the soil, ergo if the soil is low in nutrients so are your vegetables. Plants are more than N, P, and K. They may look ok, you may even have good yields, but wit modern soils they are not as nutritious as they should be. Now this may not be an earth-shattering revelation (although many reviewers are surprisingly resistant to the concept...see below), but Solomon couples it with some suggestions on how to test your soil nutrient levels, how to improve them (this is where the big expense may come in, depending on your situation), and also challenges gardening orthodoxy that suggests that veggies will be nutritionally perfect as long as they're organic. The reason I deducted 1.5 stars is that after reading the book one may not be in a position to apply what they learned; which maybe is not the author's fault, but it could arguably have been addressed in the book...perhaps a chapter on "What to do if you can't access such-and-such or can't afford to shell out hundreds of dollars on amendments or can't wait three years to build your soil."
Apparently gardening is a topic like health and diet in that everybody seems to think theirs is the Only Right Way to Do It. (This goes for Solomon too, although I think he's mostly right.) The #1 thing that strikes me about the negative reviews on Solomon is that people base their ideas on a very faulty understanding of the history of agriculture. I keep seeing the claim that people have been gardening for millennia and doing just fine without adding the amendments Solomon recommends (see reviews on Gardening When It Counts for more of the same), but this is simply not true. It is because of the bad methods used in the past that we are now reaping the whirlwind of nutrient-depleted soil. People have always done the best they could, but for most of history humans have not known about things like microscopic organisms in the soil or mycorrhizae, etc. "Put poop on it and keep digging until nothing grows there anymore" was basically the rule, until it was replaced in the 20th century by "put chemicals on it and keep digging until nothing grows there anymore." Analysis of skeletal remains shows that compared to ancient hunter-gatherers, agriculture resulted in people with rotten crooked teeth, stunted growth, crippling arthritis, and yes, major nutrient deficiencies. Remember rickets and scurvy? They still exist, you know. THIS HAS BEEN TRUE SINCE THE INCEPTION OF AGRICULTURE 10,000+ YEARS AGO AND IS STILL TRUE TODAY. Just because we're accustomed to it doesn't mean it's "natural" let alone optimal. Gardening and agriculture should never be compared to "nature" because they are examples of human INTERFERENCE with natural processes for our own ends. (This doesn't mean they are necessarily bad--but we need to be realistic.) Meanwhile, I also see many reviews saying Solomon's method is wrong because so-and-so does something different and their plants produce just fine--but unless they are doing a chemical analysis of the nutrient levels in their food, they can't compare their results to Solomon's, because he's not talking about yield, but nutritional content. It's comparing apples to oranges (har har).
Conclusion: I'm a pretty inexperienced gardener. I haven't been able to apply all of Solomon's recommendations. But I accept his basic premises based on my very rudimentary knowledge of botany and my somewhat less rudimentary knowledge of history. if you accept the abundant scientific data, archaeological remains, and historical records that show our soils are badly eroded and depleted of nutrients; if you accept that plants get their nutrients from that soil and therefore soil chemistry is the limiting factor in how nutritious your plants can be; if you want your veggies to be as nutritious as possible; and if you are willing to read a book that is dense and has formulae and stuff, then you'll benefit from this one. If on the other hand you are already convinced your way of gardening is the Right Way, why are you even buying books on the subject? Just go do your thing.
I've been nibbling around the edges of learning about soil testing for the last couple of years, but this book turned my understanding into a full (and nutrient-dense) meal. Solomon's work is based largely on Albrecht's studies of the optimal ratios of cations (calcium, magnesium, potassium, and sodium), with a lot of updates from the more modern work of Astera. Solomon breaks it all down into simple worksheets that anyone can fill out with a calculator able to multiply, add, and subtract.
A second warning is due --- you'll need to put quite a bit of cash into Solomon's method if you have a large homestead. Solomon's math only works if you do a Mehlich 3 soil test, which is about $20 per sample; then, you'll probably be committing to adding several hundred dollars' worth of amendments (like gypsum) to get your soil back in balance.
Even if you don't want to go the scientific route, though, this book is worth it for its explanation of the chemistry of soil. Highly recommended!
