8467. Klassen, Ron. 1990 June. Fertility report from the PFIN tour.. Growers Guide, p. C14, Colfax, WA 99111.
A soil building program was initiated with the addition of high calcium lime and tillage with a ridge/subsoil tool. Some observations since then include improved straw decomposition, almost no erosion, increase in soil-active herbicide effectiveness, decrease in footrot, increased yields, and rising soil organic matter levels.

8485. Klicker, R.. 1990 July. Living soil is a forgiving soil.. Wheat Life, p. 16-19, WAWG, Ritzville, WA.
Bob Klicker has used a three-step process on his farm to improve productivity and protect the soil and water: identify current problems, search for possible solutions, and test and prove a system on your own farm. he has followed a soil balancing approach for cations, used deep tillage to break up compaction, and emphasized the role of calcium. He reports yield increases, less disease, lower erosion, better tilth, less pesticide use, and lower irrigation needs for the various crops on his farm.

11116. Wegner, G.. 1992. The benefits of biosolids.. Wheat Life (April 1992), p. 11-13.
Dryland cereal farmers are beginning to test the value of biosolids (treated sewage sludge) on their fields. Gary Wegner has found that his crop yields are increasing where biosolids are applied, perhaps due to addition of trace elements such as zinc. Also, biosolids add organic matter which improves soil structure and reduces erosion potential. Biosolids are a free source of nutrients for farmers, but not enough are available to cover very many acres each year.

11204. Matheson, N., B. Rusmore, J.R. Sims, M. Spengler, and E.L. Michalson. 1991. Cereal-legume cropping systems: nine farm case studies in the dryland northern plains, Canadian prairies, and intermountain Northwest.. AERO, 44 N. Last Chance Gulch, Helena, MT 59601.
The farm case studies presented in this book include details of the crop rotations, tillage, fertilization, and pest control practices used by the farms. Farms were chosen for their innovative or alternative practices. Partial budgets for each crop on each farm are presented to provide a reference point for the economic performance of alternative dryland cropping systems. Comparisons with more conventional systems are not made.
