Last week Morris Marsolek, consultant to Calcium Products, Jim Milam, Turf Sales with Calcium Products, and I spent a day in Los Angeles. While it was not really a vacation, the weather was a nice break from tornados, hail and down pours.

The reason for my trip was to meet the owners of Wallace Laboratories. Calcium Products has long relied on the expertise of Dr. Arthur Wallace and Dr. Garn Wallace.

Many agronomists and researchers in the Midwest may not have heard of the Wallaces, however west of the Rockies they are well known.

The Wallaces have over 70 years of combined experience in plant physiology, soil science, ecology and plant nutrition with over 600 publications. They have authored special issues in Soil Science, Journal of Plant Nutrition, Communications in Soil Science and Plant Analysis.

These articles cover, revegetation of disturbed lands, plant analysis to assess mineral needs of plants, determination of normal and abnormal nutrient concentrations, chelated micronutrients in plant nutrition, iron nutrition, excess trace elements in soil and plants, multiple action factors on plant growth and improvement of the physical properties of soil.

In addition to numerous publications and laboratory services, Dr. Garn Wallace also offers consulting. When we at Calcium Products have a question that we can not find the answer to, 9 times out of 10 Dr. Garn Wallace will be able answer it.

Thanks again for letting us visit, and keep up the good work!

Arthur Wallace, Ph. D., Professor Emeritus, UCLA, Department of Agricultural Sciences (Soil Science and Plant Nutrition). Dr. A Wallace organized the first Iron Symposia, which is still held every year at a different location around the world. He has written many paper about he benefits of gypsum and PAM.

Garn A. Wallace, pH. D. earned his doctorate degree from UCLA in the Department of Biochemistry. He worked as a research biochemist in the Laboratory of Biomedical and Environmental sciences before forming Wallace Laboratories with Arthur Wallace. Garn has over 100 publications in the fields of plant nutrition, soil science, microbiology, plant physiology, ecology, soil conditioners, mineral excesses, water relationship in plants, mineral toxicities etc.

Wallace Labs is located at 365 Coral Circle, El Segundo, CA 90245, (310) 615-0116.

Many of the books written by Drs. Wallace are available on their website.

Were not going to talk about the handy and tasty vegitable spray. We want you to introduce you to PAM, a.k.a polyacrylamides. While increasing soil quality and organic matter to combat soil erosion is the ultimate goal, PAM is a product that can help today. There have been many acres of marginal ground broken in the last year, some soil is highly erodeable, some is of poor quality. SuperCal 98G and SuperCal SO4 will help improve the soil structure over time, PAM can help reduce erosion and increase infiltration the moment it’s applied. 

PAM is an environmentally friendly, water-soluble substance that  binds soil into particles that are too large to be carried away by typical runoff. PAM binds particles of silt and clay together, making them more resistant to erosion.

In the U.S., PAM’s are used extensively in potable water treatment, for dewatering of sewerage sludges, washing and pealing of fruits and vegetables, clarification of sugar juice and liquor, in adhesives and paper in contact with food, as thickeners and suspending agents in animal feeds, in cosmetics. No significant negative impacts have been documented for aquatic, or crop species when PAM is applied at recommended concentrations and rates.

PAM has proven to

• Reduce sediment runoff soil loss 80% - 98%
• Increases water infiltration up to 60%
• Lowers concentration of nitrogen, phosphorus & pesticides in runoff water
• Reduces hardening and crusting of soils
• Aids in plant growth on high-grade slopes
• No bioaccumulation in crops
• Cost effective and time saving

Conservation practices that require additional field operations usually occur during busy periods in the farming schedule are also avoided. Furthermore, conservation practices that reduce sediment loss such as; sediment ponds, vegetative filter strips or buried-pipe waste water systems, still lose most of the clay-sized solids, the soil component most critical to sustained soil fertility. These solids also are most linked to pesticide, and nutrient loss in run-off waters.

Halting erosion prevents exposure of soil not treated with herbicides, thus reducing potential late-season weed problems. Applied pesticide and fertilizer inputs are better retained on the field. Uniform water infiltration from upper to lower field ends, has shown to improve potato yield and grade, and reduces the risk of nitrate leaching.

Many farmers, who have viewed traditional conservation practices as cumbersome, intrusive, or ineffectual, and expensive, adopt PAM as an attractive inexpensive alternative. The typical $15 to $35/acre per crop is partially or entirely returned by savings in erosion-related field operations, improved infiltration, water conservation, or crop responses.

We hope this short introduction to PAM gives you some ideas to help your marginal, and highly productive irrigated ground be more productive. This article was condensed from polymersinc.com. Read the entire article here.
