  • The Broadfork

    The Broadfork

    The BroadFork Many gardeners and growers, especially those working on heavy soils, face the difficulty of deeply compacted soil and want to loosen and aerate it without bringing lower layers to the surface. On a field scale there are tractor-based solutions, but how to tackle the task in the smaller plot? The BroadFork is designed to be at least part of the solution! (The Glaser Bio cultivator (414) has the same objective.) Here are some of Eliot Coleman’s comments from his book The New Organic Grower:– “This two-handled deep tillage tool is known by different names, but broadfork comes as close to describing it as any other. Like most agricultural tools its genesis surely dates far back in agricultural history. It consists of a 2-foot wide spading fork with a 5-foot-long handle at either side of the fork. The teeth on the fork are spaced 4 inches apart and are about 12 inches long . The tines are designed with a parabolic shape and curve down from an attachment point at the back of the crossbar. This difference is the key. The parabolic curve . works with an easy, rolling motion. As the handles are pulled down, the tines curve under and lift the soil easily. “The broadfork is held with the handles tilted slightly forward of vertical. It is pressed into the soil as far as possible by stepping on the crossbar, then the two handles are pulled back towards the operator in an easy rocking motion. The broadfork is then lifted from the loosened soil, the operator steps backwards 6 inches, and the manoeuvre is repeated..

Soil pH, soil organic matter (SOM), total nitrogen (TN), available phosphorus (AP) and potassium (AK) were determined for the samples taken in 2017 and compared to results from the paired samples collected in 1980 by grouping all samples into four cropping systems: continuous paddy fields, new paddy fields developed from uplands, continuous uplands, and new uplands developed from paddy soils. The results show a significant increase in soil pH, AP and AK in all cropping systems, which was, however, coupled with low fertilizer use efficiency.
  • Soils – Fundamental Concepts

    Soils – Fundamental Concepts

    NRCS Soil: Fundamental Concepts Scoop on Soil Educational CD May 2006 Soils – Fundamental Concepts The Soil In Perspective: A fundamental knowledge of soil science is a prerequisite to meeting the many natural resource challenges that will face humanity in the 21st Century. It is also true that the study of soils can be both fascinating and intellectually satisfying. It is in the soils that we are able to observe all of the principles of biology, chemistry, and physics at work. It is the understanding of these principles which enables us to minimize the degradation and destruction of one of our most important natural resources. Much of our life’s activities and pursuits are related to and influenced by the behavior of the soil around our houses, roads, septic and sewage disposal systems, airports, parks, farms, forests, schools, and shopping centers. It is essential that conservation professionals understand the soils on which we build and design and work. In any field of natural resources, it is important to understand the soil properties which impact the application of technology as we use it to preserve and protect our most basic natural resource, our soils. Soil Defined: We have several definitions of soil depending on the discipline providing the definition: Geologic definition – loose surface of the earth as distinguished from solid bedrock. (Support of plant life not required) Traditional definition – material which nourishes and supports growing plants. (Includes rocks, water, snow, and even air – all of which are capable of supporting plant life) Component definition – mixture of mineral matter, organic matter, water and air.

    The Asper Family Garden

    The Asper Family Garden Lamplighter Guild Challenge: Horticulture Submitted by Julia and Aaron Asper May 1, 2020 Since God brought Aaron and I together, we have had homesteading on our hearts. We want to keep our (hopefully!) big family together, busy, happy, and healthy, and we believe farming together is God’s plan for our family. Since marriage, we have lived in an established neighborhood in SC with a backyard to host a small flock of chickens, vegetable garden, and a bunch of children’s toys. The three just didn’t work out well together! We prayed, saved, and hoped for our own land. We traveled between SC and PA, my husband’s childhood home, seeking but always praying for the Lord’s will, and his answer was, “Not yet.” Now, after 6 years of marriage, we have 3 children, a good church, a good job with a family oriented company, yet many homesteading property hopes deferred. Again, we prayed for the Lord’s will. I told my husband, “If God could bring us together, even though I’m from SC and you’re from PA, then He will bring the property to you.” “To the front door?” my husband replied, “That’s impossible.” Still, I encouraged that he knows what we need, so we don’t need to be discouraged. He will make it happen as He knows best. Then, it happened! At the beginning of 2020, our kind neighbors announced their son and family were moving. Then one morning, their son drove by while my husband was in the front yard and asked him if we be interested in renting their newly renovated, home on 12 acres for only an affordable little bit more per month than we were currently paying.

Doran∗ USDA-ARS, 116 Keim Hall, University of Nebraska, Lincoln, NE 68583-0934, USA Abstract Interest in the quality and health of soil has been stimulated by recent awareness that soil is vital to both production of food and fiber and global ecosystems function. Soil health, or quality, can be broadly defined as the capacity of a living soil to func- tion, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain or enhance water and air quality, and promote plant and animal health. Soil quality and health change over time due to natural events or human im- pacts.
