State Reports

Submitted by Morteza Mozaffari. In process of filling data entry and soil receiving positions. Changing from M3 1:7 extraction ratio to standard extraction ratio of 1:10, making change in fertilizer recommendations, change in reporting units from lbs/acre to ppm, and change in reporting format and delivery method - starting July 1, 2005. Developed procedures for measurements of soluble P, NO3, and NH4 by auto analyzer. Did a comparison study of soil test results and fertilizer recommendations for pH, EC, and extractable nutrients by the Marianna lab and a commercial lab. Plan to publish results. Revised program for fertilizer recommendations for rice to incorporate new cultivars. Marianna lab sample totals: soil - 100,014 (18% grid samples), cotton petiole - 5,318. Fayetteville lab sample totals: manure - 1,420, forage - 1,389, plant - 9,124, soil - 3,111, extracts - 10,533.

Submitted by Leticia Sonon. Effective July, 2004, farmers are charged $6/sample for routine soil test. Fees were also increased on other tests. Evaluating new methods for soil pH and lime requirement. Measurement pH in 0.01 M CaCl2 and determine soil pH buffering capacity by measuring the change in pH after adding Ca(OH)2. Plans to implement this fall. Ongoing research on water soluble phosphorus in poultry litter. New video, "Well: What Do You Know", designed to educate rural well owners about proper construction, maintenance, and testing of private drinking water wells. FEW lab passed the onsite audit and provisionally certified to measure bacteria in public water systems. NIR calibrations for In-vitro Total Dry Matter Digestibility have been completed and presently being validated. Georgia Environmental Protection Division doubled in sample numbers since last year.

Submitted by Frank Sikora, D. Reid, and Paula Howe. The soil test web site at http://soils.rs.uky.edu/ contains information on services and calculators for determining fertilizer, lime, and manure application rates. In 2003, lab analyzed 30,349 agriculture, 5,875 home lawn and garden, 601 commercial horticulture, 54 greenhouse, 6,736 research, 20 atrazine residue in soil, 327 animal waste, 28 nutrient solution, and 662 special research solutions.

Submitted by Jim Wang. Improvement of lab result reporting through e-mail by consolidating pages for multiple samples. Working to create a common webpage for producer to search for information. Added new C/N analyzer (LECO TruSpec CN) - now offer soil total organic C analysis. Purchased CEM MARS 5 microwave for tissue sample digestion. Evaluating Si determinations by different extraction and detection methods. Re-examining methods for sulfur and micro nutrients for sugarcane production. Research lab purchased Spectro ICP.

Digestion room renovated with two new fume hoods. Also, renovated exhaust system in the grinding room.

South Carolina
Submitted by Kathy Moore. Research lab with two technicians moved from on campus into Ag Service lab. Added new equipment including CN Elementar Macro. Increased load of plant tissue research samples. Lab was reorganized from Extension into Regulatory. Budget will be finalized for the move the first of next fiscal year. Analyzed 34,389 soil, 5,289 plant tissue, 1,677 feed, 364 water, 1,586 manure, and 6,390 solutions.

Submitted by Hugh Savoy. In 2003, 19,653 soil tests were conducted and recommendations made. Soil test numbers have been higher this year so far. No major changes to the laboratory program. The Biosystems Engineering and Environmental Science Department maintains responsibility for the laboratory program in Nashville. No major changes in soils faculty. The Extension soil management position that was lost will most likely stay lost. There appears to be no current plans for filling the soil fertility position vacated due to retirement.

Submitted by Steve Heckendorn. By the end of the year, Virginia Tech will switch from using a water pH and texture, to the Mehlich buffer to determine a lime recommendation.
