Homemade Fertilizers

With the economy and farm finance more and more problematic, interest is growing in running farms with fewer, more accurate and less expensive inputs and homemade fertilizers can help cut costs and keep fertility on the farm.

Formerly we’ve overdosed with a plethora of harsh fertilizers — especially nitrogen. As a result we’ve burned up the better part of our soil carbon, and this has reduced our rainfall.

By burning off carbon, we have created droughts even as ocean warming has sent more evaporation into the atmosphere. We have ignored that few things have more affinity for hydrogen than carbon, and if we want rain to adhere to and permeate our soils we need to build soil carbon.

We thought salt fertilizers were cheap, and the stunning results encouraged us to wish away any hidden costs, no matter that earthworms disappeared simultaneously with the food chain that supported them. Our soils got hard and sticky as magnesium stayed behind while nitrates leached, carrying away silicon, calcium and trace minerals. The soil fused when wet, shed water when it rained, and we continued to get less for more.

As if this wasn’t enough, the mind-set we were sold was get big or get out. As our net margins dried up and our future prospects evaporated, our water dried up and our land became exhausted. Continue Reading →

Tractor Time Episode 12: Edwin Blosser, Farmer and Founder of Midwest Bio-Systems

It’s Tractor Time podcast, brought to you by Acres U.S.A., the Voice of Eco Agriculture. This was recorded on Nov. 2, 2017, in Greeley, Colorado.

We’re going deep into eco-agriculture this hour. This episode’s guest is Edwin Blosser, a longtime instructor in the art of crafting and utilizing high-quality compost in production-scale agriculture. He’ll talk about specific compounds in compost to build, advise about cover crops, and help us connect the dots between profitability and soil structure.

But first, I thought I’d share a story. Earlier this week, I got a call from Ulrich Schreier. For those who don’t know, he’s one of the original advisors to Acres U.S.A., attended our conference early in our history, and now lives in France and leads a team of researchers looking at biodynamics. We’ll share that research at some point once we review it.

His quote, which is really what I wanted to share, has been my beacon of motivation this week. And a lot of you might benefit. Before hanging up, he told me: “There are a lot of cracks showing in conventional agriculture that my generation helped create, but now the real work begins. Find those cracks. And plant as many of your Acres U.S.A. trees in them as you can.”

Cover Cropping & Green Manures

After 22 years of farming, my farm’s soil is markedly more fertile and productive. It has been a wonderful journey learning what works and how to continue to improve long-term productivity while harvesting bountiful crops.

There are several methods that deserve credit for this increase in soil quality: the use of compost, the use of a balanced mineral fertilizer and a serious commitment to cover cropping.

For this article I want to focus on the growing of cover crops and green manures. When I became the farm manager at Potomac Vegetable Farms – West in 1992, I sought advice on how to transition the farm into organic production.

The land had been growing mostly sweet corn, pumpkins and green beans with commercial chemical fertilizers and herbicides. The soil was biologically inactive and nutrients were missing. I can clearly remember the words from a fertility consultant, “I can sell you something in a bag, and I can sell you something in a bucket, but what you really need to do is to make compost and grow cover crops.” And thus began my journey into both compost-making and cover cropping.

Why take on both of those jobs rather than just one? Well, they go hand in hand, each leveraging the benefits of the other to move a soil more quickly toward health and resilience.

Campus Composting

In 2009, with my retirement from Ohio University looming, I didn’t think my personal involvement in the construction and start-up of a class 2 campus composting facility would develop into such a large operation. Class 2 compost (according to the Ohio Environmental Protection Agency) consists of yard, agriculture, animal, or food waste, plus a bulking agent.

To get this project underway, thousands of yards of dirt on the campus’s periphery had to be moved to prepare the site and many yards of concrete were poured to construct the base of a metal pole barn, which would eventually house the composting machine.

Hauled by truck from Ottawa, Canada, the enormous composting machine was unloaded by crane and placed on the concrete pad.

The vertical posts were installed and metal siding attached. For power, electricity was connected and the solar array installed. Today, the Ohio University Composting facility also boasts a solar thermal system and waste oil heaters that use leftover oil from the university’s facilities operations. Skylights provide indirect lighting. The entire facility is self-sustainable. With a 10 kilowatt-per-hour built in 2009 and a 31.1 kilowatt-per-hour system added in 2012, the solar array produces more energy than is used in the operation.

Liquid Organic Matter Can Save Costs, Increase Yields

Plants, when delivered liquid organic matter, have been proven to use less and make a higher yield.

Organic matter improves tilling properties and increases soil water holding capacity in soil. It also makes nutrients in soil more readily available to plants as they leach through soil at minimum rates. Most importantly, due to their unique chemical and physical compositions, organic matter-bound nutrients have been proven to be very efficiently utilized by plants. Organic matter is no doubt one of the most important key ingredients to increase soil productivity, which ultimately results in higher crop yields.

However, there are many types of organic matter with different methods of application, in which practicability and efficiency can be a concern. Canadian Humalite International Inc. of Edmonton, Alberta, Canada, has been making an effort to mitigate this challenge by utilizing low-quality coal (non-hazardous material, energy value around 7,000 BTU/lb) as a source of organic matter. This material is transported from the mine, crushed, liquefied, combined with nutrients, and then applied to soil and/or plants. Rather than using it as a non-efficient source of energy, this coal material is developed into products which are beneficial to soil.

The products are applied to soil/seeds, seedlings, and plants up to 15 percent flowering through drip irrigation and pivot/spray systems. Significant yield increases have been observed on various crops grown in different types of soil and climate regions in Canada and the United States. The following example is one of the most recent findings obtained from a field trial completed in Forrestburg, Alberta, Canada, in 2013. Continue Reading →

Composting Tips and Strategies for Balanced Compost

Composting tips are common to find, but information to build a composting program is really what most people are seeking.

Charles Walters, as quoted in Secrets of the Soil, by Peter Tompkins and Christopher Bird, says of microbial life: “There are more kinds and numbers of minute livestock hidden in the shallows and depths of an acre of soil than ever walk the surface of that field.”

As much as a cattle rancher’s livelihood depends on healthy livestock, he and his cattle’s very lives depend on armies of beneficial microbes for survival. Microbes are the foundation for all life on earth; without them the earth would be nothing more than a barren rock. There would be no fertile soils, no plants, no trees, no insects, no animals and no humans.

Soil bacteria secrete acids that break down rocks, and enzymes that break down dead plant and animal matter into rich, life-giving soil, while transforming minerals into forms that are usable to plants. Microbes help prevent soil erosion, combat disease organisms that attack plants, animals and humans, and are an important link our food chain.
