The influence of salts on the determination of soil:water pH
Bob
presented information on obtaining soil pH in 0.01 M CaCl2
highlighting advantages in its use over water such as matrix matching with
calibration standards, quicker response time, and less variability in pH from fields with varying salt content
throughout the season.
2:00
PM Antonio Mallarino,
Long
term soil test P and K trends in relation to nutrient removal
--
Antonio presented field research on quantifying changes in P and K removals
using grain concentrations of these elements and yield. Short term changes in soil test values should
not be a concern because of year-to-year variability observed.
Fertility
issues in switchgrass production
--
Don presented agronomic research on switchgrass production. Switchgrass can withstand very low soil
fertility. Phosphorus and K
recommendations are only required if soil test levels are in the low
range. No lime is recommended with pH 5
and above.

The national soil
test manual effort headed up by the S889 committee of the SSSA was
discussed. Bryan Hopkins is the current
chair of this committee. There was
confusion on the contents of the national manual and the role SERA6 has in its
development. Opinions were raised that
SERA6 should have a greater role in its development.
Charlie Mitchell
presented the progress of the cotton publication entitled “Research Based Soil
Test Interpretations and Recommendations for Cotton on Coastal Plain Soil”.
Dave Kissel
reported no progress on the CEC fact sheet.
This topic was decided to be moved of the list
of publications until some future date.
Debbie Joines
indicated she would put together a fact sheet on copper deficiency in cattle
that would summarize what she learned in her graduate research project.
Hugh Savoy
indicated he still has not received an ISBN number for the Southern Coop Series
190 revision.
Frank Sikora
proposed the work on the ICP vs color-P fact sheet be developed into a research
publication.
9:00 AM Technical Session – Oral Presentations
1. Comparison between ICP-P and Colorimetric-P
Analysis in Mehlich Extracts, Frank Sikora
Data from the
interlaboratory study involving several labs was reviewed and presented. The data from this study along with data from
NCR-13 and NAPT was proposed to be combined into a research paper to be
submitted to Communications in Soil Science and Plant Analysis.
2. Immediate and Residual Nitrogen Availability
from Pelleted Poultry Manure and Urea for Corn, Morteza Mozafferi
Morteza presented
field research on pelleted poultry litter which showed the same N availability
as non-pelleted poultry litter. About
50% of total N is available the first year and 10 to 20% residual N is
available the following year.
3. Fertility of Vinifera Grapes in NC, David
Hardy
David presented soil
fertility work on grapes.
4. Rapid Determination of the pH Buffering
Capacity of Soils, David Kissel.
David presented
laboratory research on quantifying the pH buffer capacity of soil using calcium
hydroxide additions. Longer reaction
times of up to 4 days were found to be needed to achieve pH equilibrium.
1. Internal Support for State Laboratories,
David Kissel
David led a
discussion on the importance of state funded soil test laboratories. Advantages discussed were unbiased fertility
recommendations and the close ties with research activities. The

State Reports
Instrumentation
The Soil, Water
and Forage Testing Laboratory has either added or is in the process of adding
the following instrumentation to enhance its analytical capacity:
1) Spectro Genesis Radial ICP
2) Spectro Arcos Axial ICP
3) Elementar
LiquidTOX II soluble carbon/nitrogen analyzer
4) Lignin 10 cup
pH and conductivity robot

Sample analyses
During calendar year 2007, the laboratory
processed"
28940 soil, 1333
water, 6579 plant/forage, 1799 biosolid and 8738 research samples.
The Soil, Plant and
Forage and grain
analysis at SPPC experienced enormous growth in 2007. Our staff processed 1536 forage and grain
samples (65% increase over 2006) for producers across the state. Suffering from severe drought, farmers
realized the importance of nutritional information especially due to low feed
supplies. The drought also increased
likelihood of nitrate poisoning in cattle, thus the Center implemented (first
ever) nitrate testing free of charge.
Over 1,100 samples were tested for nitrates with results being called
back to the producer, in many cases within 24 hours. By fall, work was being done in the
laboratory to implement a fee based nitrate analysis to be offered February
2008.
In 2007, samples received for soil testing increased 9%
over the previous year for a total of 23,417.
This year, we added calcium and magnesium to the Basic soil test,
providing more information at the same price of $6.00 per sample. Additional analyses were also added in terms
of packages and individual analyses.
Soil carbon analysis (Elantech CNS Analyzer purchased in 2007) was added
in the fall to take place of Walkley-Black method used for measuring organic
matter.
JB
Jones has been working with us to update our soil fertility
recommendations. We're planning on
putting the updated recs in place August 1.
We
purchased and installed (in April) a new Spectro ARCOS ICP (radial). We had some initial hardware problems, but it
seems to be running smoothly now.
We
are 3 years into a 5 year plan to become totally self supporting. Each year, we've been given substantial cuts to
our state salary and fringe money. So
far, we've been able to handle our building and operating expenses and the
state cuts with our lab testing revenue, but at this point, we can't take
another cut without going into the red.
We are working toward running more samples and we'll be reviewing our
fee schedule. Time will tell what's
going to happen at the end of the next 2 yearsSample
totals for 2007 were .39,808
soil, 3,045 plant, 1,391 feed, 384 water, 1,937 waste, and 5,597 other.
Sample volume increased to about
60,000 in 2007 due to mostly research sample increase. We tested 33,070 soil,
3,529 water, 3,323 forage, 1,021waste, and 18,752 various research samples
during the year.
We have 2 Spectro Ciros ICP,
2 Lachats and 2 LECO TruSpec C/N Analyzer in service. We added another FIA and
it seems doing well.
Several new positions in
soils area (Nutrient management, soil physics, soil and water conservation and
management) have been refilled after vacant for several years.
The Soil Testing Section analyzed 333,512 soil samples and supplied lime
and fertilizer recommendations through 39,155 reports, in an all-time record
year. Sample volume was up 9% over FY2006 and surpassed the all-time record of
2001 by 4%. Turn-around time never
exceeded 7 weeks and, for much of the peak testing period, samples were
processed in about 4 weeks or less.
The following crops accounted for sample volume: tobacco: 2.3%, corn- 17.4%, small grain- 5.3%, soybeans-6.9%, small grain – soybean double-crop-2.5%, peanuts-1.1%, cotton-28.6%, pasture & hay- 6.9%sweet potato- 1.6%, Christmas tree-1.2%, managed turf- 6.9%, homegrounds- 13.7%.
No new purchases were made for the lab; however, we are planning on purchasing a new ICP (Spectro- Arcos) this summer. A new lab supervisor was hired in October, 2007 but he did not make probation so this position is currently open.
The lab is meeting compliance of USDA-APHIS with witchweed concerns by sterilizing soils from farms where infestation is known 5 southeastern counties. This requires segregation of samples by using a red soil box, the purchase of a new sterilization oven and disposal of sterilized soil in a different vessel into the landfill.
We are currently conducting research on P and K
recommendations for Leyland Cypress through a greenhouse study in cooperation
with Dr. Eric Hinesley and are in our third year of work with studying
fertility of vinifera grapes in the Piedmont region of the state in cooperation
with Dr. John Havlin. We published our work on pH recommendations for Leyland
Cypress in cooperation with Dr. Hinesley:
Soil pH and Fertility Affect
Growth of Leyland Cypress Christmas Trees (J. Environ. Hort. 26(1):4–8.
March 2008). A new crop code was established for
Our public access system for downloading reports and inquiries was revised in 2007. We are still in need of LIMS upgrades and are seeking funds to improve / rewrite LIMS. We have also made available our annual state soil test summary data on-line http://www.ncagr.com/agronomi/STdata2007.htm.
The Mississippi
State University Extension Service Soil Testing Laboratory ran 25,568 soil and
1,492 tissue samples in the fiscal year 2007-2008. Several new or updated soil
fertility and/or soil testing related publications have been posted to
MSUcares.com for Print-On-Demand by interested parties. Dr. Jac Varco assumed
the duties of Interim Department Head, Plant and Soil Sciences, on
The LSU AgCenter Soil Testing
and Plant Analysis Laboratory analyzed 20,488 routine soil samples, 3,539 plant
samples and 237 irrigation water samples in 2007. For routine soil analysis,
91% of samples were submitted from producers and 9% from LSU AgCenter
researchers and extension personnel. In addition, the lab also analyzed
6,613soil samples for optional tests. These numbers of soil samples reflected
an increase of 20% in samples for routine tests submitted from producers but a
decrease of 19% in samples for optional tests submission.
The Lab acquired a AS3010
Dual pH Analyser from Labfit which replaced a Labtronics system. This has streamlined the pH measurement.
The Lab evaluated
measurements of biological oxygen demand (BOD) at different incubation time of
suspension samples and their relations to carbon and nitrogen in the measured
system. The purpose was to seek alternatives
to speed up BOD measurements.
The lab also evaluated
residual interaction effects of liming and K fertilization on soybean growth in
an acidic Gigger silt loam as well as nutrient uptake efficiency for selected
corn and sugarcane varieties based on tissue test, soil test and crop yield.

As a part of recent re-structuring,
starting October 2007, the research and extension labs have been placed under
the newly formed, ‘IFAS Analytical Services Laboratories’ (ASL). The ASL now
comprises of four components- the Environmental Water Quality Laboratory (EWQL)
for all NELAP certified analyses, the
A new Astoria-Pacific
autoanalyzer has been purchased in June, 2008 to replace the previous
instrument running TKN. The new machine has two channels with two detectors,
doubling throughput of the samples.
Three auto-sampler units have
been purchased in June 2008 to replace the older auto-samplers for TP/OP, and
nitrate instruments.
Due to budget reductions, the
lab has picked up salaries of three analysts in the lab from the revenues. As a
part of achieving self-sufficiency, it is projected that two more positions
will be moved from state funding to lab revenues during the next two years,
thereby reducing the state funded lines from 10 to 5.
New test protocols and
procedures for Bahiagrass pastures and commercial citrus producers have been
developed and implemented
Search for a new Lab Manager
is on-going and is expected to be finalized by August, 2008.

E. Active Participation in Training Animal
Operators and Planners Engaged in Comprehensive Nutrient Management:
A
laboratory representative provides yearly trainings to animal operators and
planners on how and when to collect soil samples, manure, and water from
monitoring wells. Soil and manure testing are needed to perform comprehensive
nutrient management planning (CNMP). Utilization of manure or lagoon effluent within a CNMP
requires soil and manure testing for measurement of plant available
nutrients. Soil test reports give the
level of available plant nutrients and provide recommendations for any
additional lime and fertilizer nutrients needed to achieve optimum crop yields.
