Identifying gypsum-responsive soils
Farmnote 57/1990
by Fionnuala Frost, Research Officer, National Soil Conservation Program and Garry Orr, Technical Officer, Division of Resource Management, Merredin Soils containing dispersible clays are often problem soils. A dispersible clay is a clay that does not stay stable when wetted, but slakes or disperses easily. The major problem with dispersed clay is that it can block soil pores and reduce the permeability to water. The clay also acts as a cement that hardens the soil when it dries. Gypsum applied to soils with dispersible clays improves the permeability to water by reducing the dispersion of the clay. Reducing the dispersion allows more of the rainfall to enter the soil, reducing run-off and erosion risks and improving drainage after heavy rains. The action of the dispersed clay in hardening the soil (or increasing soil strength) is also decreased by applying gypsum. The lower soil strength allows for more timely cultivation and seeding. Energy inputs and machinery maintenance can be reduced, while decreased soil strength also allows improved crop performance from rapid emergence, improved aeration and efficient water use. The benefits from applying gypsum will vary, depending on the season. Apply gypsum with the aim of adopting more sustainable, reduced tillage, rather than continuing with multiple workings and having to reapply gypsum a few years later.

Organic Agriculture Fights Back
Critics of organic agriculture claim that it is based more on ideology than on environmental or economic merit. Lim Li Ching reviews the evidence and turns the table on the critics. If you wish to see the complete document with references, please consider becoming a member or friend of ISIS. Full details here Organic farming has been denigrated for being less efficient in land use and having lower yields than conventional farming, and even accused of posing potential health risks. According to a commentary in Nature by Anthony Trewavas, Fellow of the United Kingdom Royal Society, "Although its supporters assert that organic agriculture is superior to other farming methods, the lack of scientific studies means that this claim cannot be substantiated". But he is wrong, there

Soils are our future: Natural systems agriculture
From the earth we come, to the earth we return, and while on earth we live by her fruits. Soil scientist Hans Jenny (1954) By Jerry Glover
The Land Institute
As our cultural identities become increasingly subsumed into technological identities focusing on what we can, or hope, to become, we have largely ceased considering the wellspring of our physical and chemical makeup. That wellspring - the Earth's soil - is a relatively thin and fragile but biologically active layer of the Earth's surface through which nearly all of the elements necessary for our bodily past, present and future must cycle. Soil is the elemental recycling center that provides our human DNA with a past and present. Without soil, human DNA has no future. For those of us who inhabit the North American Great Plains and Midwest, the future depends on soils developed in prairie ecosystems that covered a large portion of the continent little more than a century ago. These prairie soils, some of the most inherently fertile soils in the world, are the product of near-miraculous management of nutrients, water and sunlight over long stretches of time. Much of the effectiveness of the prairie system derives from its vegetative structure that consists primarily of mixtures of warm and cool season grasses, legumes and members of the sunflower family. These diverse, perennial plant assemblages evolved over tens of millennia, under the pressure of constant resource constraints, to capture and hold onto anything the system offered that could be used to fix carbon from the atmosphere, set seed and expand roots into the soil. The triumphant assemblages are those systems that waste little, produce much and save for the future.

Production Agriculture/Soils and Crops
There is a growing need for highly skilled employees in the production agriculture industry in Wisconsin. By training Youth Apprentices, agriculture employers can play an active role in shaping the quality of their future workforce, improving the skill level of potential workers, and enhancing their competitive positioning in the marketplace. This program provides a framework for educators and industry to work together to produce work-ready, entry-level employees whose efficiency, productivity and flexibility will compete favorably in the global market while integrating academic and work-based learning in school and the workplace. Youth Apprenticeship is a rigorous two-year elective program that combines academic and technical classroom instruction with mentored on-the-job paid training for high school students. The Production Agriculture Youth Apprenticeship is a unique program which combines two successful work experience programs - Youth Apprenticeship and Cooperative Education Skill Certificate Program (Co-op). Level Two - Youth Apprenticeship Students continue their work experience and receive classroom instruction that supports either animal science or soils and crop production. Competency areas include core abilities, safety, ag mechanics, ag facilities and materials handling, crop production, and dairy and livestock production.

    Remote Sensing and Precision Agriculture
    [This page is based largely on information compiled for a presentation at the 3rd International Conference on Precision Agriculture, June 23-26, 1996, in Minneapolis, MN (see Barnes et al., 1996)]. Remote sensing has shown potential for use in agricultural management for a number of years; however, the availability of fine spatial resolution, near real-time data has limited its application in the past (Jackson, 1984). New companies that provide aircraft-based imagery to meet the resolution and temporal requirements for agricultural management are now emerging. The promise of commercially available, high-resolution satellite imagery will also provide additional sources of remotely sensed data (Fritz, 1996). Advances in precision farming technology (geographic information systems [GIS], global positioning systems, and variable rate equipment) provide the tools needed to apply information from multispectral images to management problems. There is still considerable work to be done before the full benefits of remotely sensed data can be realized, but there are applications that can benefit from this data at the present time. Following are a few examples of how remote sensing can currently meet some of the information needs in precision agriculture. EXAMPLE APPLICATIONS Soil Properties Soil physical properties such as organic matter have been correlated to specific spectral responses (Dalal and Henry, 1986; Shonk et al., 1991). Therefore, multispectral images have shown potential for the automated classification of soil mapping units (Leone et al., 1995). Such direct applications of remote sensing for soil mapping are limited because several other variables can impact soil reflectance such as tillage practices and moisture content. However, bare soil reflectance could have an indirect application in interpolating the results of gridded soil samples. For example

    Volcanic soils yield new clues about the emergence of powerful chiefdoms in Hawaii When the first Europeans arrived in the Hawaiian Islands in 1778, they found a thriving, complex society organized into chiefdoms whose economies were based primarily on farming. But one question has long troubled anthropologists, ecologists and historians alike: Why was large-scale sweet potato farming confined to just a few areas of Maui and Hawai'i? After all, the Polynesians first arrived in the Hawaiian archipelago around 800 A.D., so they had hundreds of years to develop potato fields throughout the islands. The answer, according to an international research team, may lie in the soil. Writing in the June 11 edition of the journal Science, the researchers conclude that relatively recent volcanic eruptions on Maui and the island of Hawai'i produced a handful of sites with soil nutritionally rich enough to raise large quantities of sweet potatoes. What's remarkable, say the authors, is that early Polynesian settlers found these fertile farmlands, which were originally covered by thick tropical forest, and successfully exploited them for hundreds of years.

It is not possible at this time to determine the complete citation for this article; it could be one of three different original publications. However, Acres has put it online and thus, effectively, tossed it into the public domain. Explains that much of the apparency of moisture stress is subsoil infertility.
