Payment plans are available and subsidized through the Young Farmer Network. Partial and full subsidies are available. Get in touch with them for payment plans through e-mail: firstname.lastname@example.org, use subject line: Big Train Soil Class
Checks may be mailed to PO 336 N Scituate RI 02857, made out to Big Train Farm
How Do I Register? Please make sure you are available for both days of class before registering. They are complementary. Then e-mail us (email@example.com) and we will register you for the course!
Instructor? Classes are led by Big Train Farm owner/manager John Kenny. John has over 15 years of experience as an organic farmer as well as an academic background in biology and chemistry. John approaches this course with a farmer to farmer/gardner focus. All though the course is science-heavy it will be presented in familiar context and analogy. For more info on John and the methods of Big Train Farm use this link.
What’s Covered? Course will include four classes covered over a two-day period (2 class/day with a break.)
Class One Physical, Chemical, Biological Nature of Soil
* Physical Structure and Intro to Scale – delving into the basic, foundational structure of soil and it’s New England natural history. Scale is an important issue when dealing with soil due to it’s microscopic nature.
* Chemical Processes, Form and Function – On the microscopic level matter functions on a chemical scale, dominated by the forces of electro-magnetism. We will introduce the mechanisms of how soil constituents interact
* Cation Exchange – An understanding of how soil functions is partly concerned with how elemental nutrition is held (or sorbed) onto soil minerals and organic matter. Cation and Anion exchange capacity will help us understand where our mineral nutrition resides in soil.
* Organic Matter, Origins, Form and Function – What is soil organic matter exactly? Where does it come from and how does it impact our soil? Why does it seem so important to organic agriculture? We will look in detail at how organic matter matters to soil productivity and function and how to maintain it.
* Rhizosphere, Phyloplane, Intro to Microbial Life – The wonderfully complex world of soil life is introduced here. How it fits into the mineral, air, and water categories of soil composition will be discussed.
* Mycorrhizae – The particular role of fungi in the soil will be introduced in class one and expanded on in class three and four.
* Nitrogen, Case Study in a Nutrient Cycle – With what we’ve learned from our exploration of the four Aristotelean Elements of soil (water, air, earth, fire) we will discuss the role of these elements in the nitrogen cycle as it pertains to crop fertility.
* Chemical Nutrition, Form and Function – Now that we understand the constituents of soil we will examine the role they play in plant growth. What are the building blocks of plants? All the plant nutritional elements besides carbon, oxygen, and hydrogen are supplied either exclusively or primarily from the soil. This class will focus on the way plants thrive with proper elemental nutrition.
* Photosynthesis – the chemical reactions of photosynthesis and the by-products resulting are the foundation of plant growth (and all life on earth). Let’s take a close look at this process and see how it works in order to understand how we can manage it.
* From Elements to Compounds to Tissues – From the reaction of photosynthesis plants build their own metabolic compounds and tissues. How do soil nutrients fit into this web of biology? Where does, for instance, sulfur or calcium exist and function once it is taken up by a plant?
* Nutrient Mobility in Plants – Observing nutrient mobility (or how nutrients are translocated around a plant) is an important way for us to understand plant health and productivity. Why are some nutrients mobile and some not? What does this tell us about, say, our crop health?
* Plant Health, Immunity, and Nutrition – Organic farming philosophy holds that promoting a healthy plant can reduce or completely exclude pest and disease pressure. We will explore this controversial topic and discuss the role nutrition plays in plant immunity
* Growing Practices, Effect on Soil, Plants – We will briefly introduce the role farming practices have on soil and crop health. How do we improve our methods in order to grow better crops? We will explore this topic in detail in classes three and four…
* Mineral Composition: Who’s Got the Right Numbers? – From one soil test to another it can be quite confusing as to what supply of mineral nutrition we have in our soil. What is the significance of nutrition being available or being “locked up”?
* Soil Food Web – The “food chain” or “food web” of soil is the process which allocates and maintains fertility in an organic system and is the crucial element in bringing plants to pinnacle health. Let’s observe each link in the chain and see what is happening in the microscopic ecosystem of our soil.
* Feeding the Soil, Feeding the Plant – Plants and soil biology maintain a reciprocal feeding relationship. VAM fungi, for instance, obtain much of their carbon from plants while in return supply plants with mineral nutrition mined from soil particles. They are also part of a dynamic food web where they are both predator and prey, continuing a cycle of nutrient acquisition and excretion.
* Ecological Succession – How does our soil management fit into a broader ecological context? Our practices can either mimic a forward or backward ecological succession which has a direct impact on our farms and crops.
* Microbe Ratios, Weed or Crop Promotion? – Soil biology and ecological succession follow interesting patterns of microbe ratios (for instance bacteria to fungi ratios) and nutrient ratios (for instance nitrate to ammonium ratios). What do these ratios mean for our soil? How do they effect how our farm landscapes look and behave?
* Aristotelean Elements of Soil – Understanding that fertility is NOT only a matter of how much of this or that mineral is presently in the soil is a crucial part of becoming an educated soil manager.
* Aristotelean Elements Point by Point – Water, Air, Earth, and Fire (aka Soil Life) all interact in a synergistic fashion. None of the elements are of superior importance but must be managed together considering each one’s role in your techniques.
* Farming Themes – There are some simple themes which are involved in managing each of the Aristotelean elements. We will look at each of them in detail.
* The Pyramid of Health – Farming consultants have interesting ways of conceptualizing plant and soil health. We will tease out the details and discuss them.
* Remineralization – Often presented as a foundational approach to soil fertility, remineralization will be discussed. Although we will not have time to delve into this topic in tremendous detail we will discuss resources for remineralizing soil.
* Big Train Farm – John will offer the systems that are used on Big Train Farm to manage soil fertility. To read about them generally in advance click here
* Open Discussion – Farming is a complex craft and there are as many opinions about farming as there are farmers. We can benefit from each others experiences and thoughts about the material we’ve covered in the course. We will dedicate the end of class four to an open discussion period.
