2 Sulfur as a plant nutrient requirement C-H-O-N-P-K-Ca-Mg-S Macro nutrients Macro: Lbs/Ac needed for 200 bu/ac crop removal* N P 2 O 5 K 2 O Mg S * lb Zn, Mn, B, Cu, Fe, Cl, Mo Micro nutrients Micro: Lbs/Ac needed for 200 bu/ac crop removal* Zn Mn B Cu Lbs * Greg Binford (Univ. of Delaware) Sulfur is essential in the formation of protein, enzymes, vitamins, chlorophyll in plants, and in nodule development in legumes

3 Sources of Sulfur Input and Loss INPUT S fertilizers Manure and biosolids >90% Atmospheric deposition Pesticides Plant residue Mineral weathering Irrigation water LOSS Crop harvest Leaching Runoff and erosion Volatilization (SO 2, H 2 S)

4 Why the Increasing Sulfur Concern for Corn Production in North Dakota? Nitrogen P 2 O 5 K 2 O Increasing deficiency symptoms Courtesy: Daniel Kaiser Photo Courtesy: Nick Petrie

5 Atmospheric deposition of S has declined Explain

6 Yield (Bu/Ac) Acres harvested (Millions) Increase in crop yield potentials 140 Intensification of crop production Corn yield and harvested area over time in North Dakota Acres harvested Yield Year USDA-NASSS Quick Stats Available online at uickstat.nass.usda.gov

7 Why the Increasing Sulfur Concern for Corn Production in North Dakota? Cont Less S as impurities in fertilizers and crop protection chemicals High rainfall intensity and leaching Depleted soil organic matter (SOM)

8 Where are we likely to see S deficiency (S response) in the field? Soils with low SOM levels Coarse (sandy) texture soils and high precipitation Side-slope and higher landscape positions Eroded soils Fields with no recent S fertilizer or manure application

9 Where are we likely to see S deficiency (S response) in the field? Fields grown to continuous corn Soils that are in no-till (high residue cover, low temperature, lower S mineralization) Corn following alfalfa as previous crop Typically in spots or streaks often associated with: Low OM content Plant residue cover Soil compaction and/or drainage

12 Sulfur - % corn tissue samples low or deficient 2012 vs (dry year vs. wet year) AGVISE Laboratories - >3000 tissue samples tested in each growth stage each year John Lee, Agvise

13 More Soil Samples, in and around ND, Tested Low for Sulfur in 2012 vs WHY? Warm Dry year (2012) More S near soil surface More S mineralized Good root growth early = good S uptake early Wet Cool year (2013) S moved out of surface soil Less/delayed S mineralized Delayed root growth = poor S uptake early

14 How would you identify corn S deficiency? Sulfur deficiency symptoms in Corn Yellow coloration in a striping or interveinal chlorotic pattern Generally found in younger leaves. Why? Stunting Unlike nitrogen, S is not readily remobilized from older to younger plant parts N deficiency symptoms: Yellow coloration in a 'V' shaped pattern which progresses from leaf tip to collar Progresses from older to younger leaves

15 Where/when are we least likely to see S deficiency in the field? High organic matter Each % of SOM in the plow layer contains about 100 Lbs S/Ac (Camberato, 2012) Depressions/low lying areas in the field Dry conditions in fall and spring A number of factors affect crop response to S fertilizer application

16 Corn yield as affected by rate of sulfur applied in a band at 4 sites with different soil textures (George Rehm) Sulfur applied (AS: ) Soil Texture silty clay loam silt loam loam sandy loam lbs./a bu./a

17 Response of corn at six locations in Minnesota to sulfur (Rehm, 2005) *Response is significant at P>0.05 Site/texture S applied, lb/acre 0 6 Yield, bu/acre loamy fine sand * silty clay loam * loamy fine sand * Loam * sandy loam * silt loam *

18 Corn yield at 24 lb S/acre rate as affected by different sulfur sources averaged across all small plot trial locations and years (18 site-years) (Fernandez et al., 2012) 180a 181a 173a 175a 177a ELEM GYPS AMS MES10 MES15 Sulfur source at 24 lbs S/acre ELEMental S, GYPSum, AMS (Ammonium sulfate), MES10 and 15 (MicroEssentials TM S)

19 Corn yield for the 24 lb S/acre rate as affected by different S sources averaged across 2009 and 2010 at BARC. Bars followed by the same letter are not significantly different (p>0.1) (Fernandez et al., 2012) ELEMental S, GYPSum, AMS (Ammonium sulfate), MES10 and 15 (MicroEssentials TM S)

20 Corn grain yield response to S application rate at responsive sites Sawyer et al. 2011

21 Common Sources of Sulfur Include Ammonium sulfate ( S) - can be blended with urea or other dry fertilizers (very soluble) Ammonium thiosulfate (ATS) ( S), very soluble A liquid well suited for use in fluid fertilizers such as UAN (e.g. 28%) solutions and other starter mixes Gypsum - calcium sulfate ( S) is slightly soluble Potassium magnesium sulfate (Sulpomag)

22 Common Sources of Sulfur Include Elemental S (90%) - insoluble S fertilizer not recommended for correcting S deficiency (must be oxidized by soil bacteria to the sulfate form Manure is an important source of S About 55% the total S in manure is available to crops the first year of application (Schulte and Kelling, 1992) Composted manure S analysis from over 15 samples across the state show an average of 2.9 Lbs/T

23 Would it Pay to Apply Sulfur in 2014? It depends on available information! Soil test results cannot be relied upon to predict corn response to S and S needs (Sawyer, 2012) It has been frustrating that a single test has not been found to be reliable for detecting potential for S response in corn and soybean (Sawyer et al., 2012)

24 Determining S Needs Would Depend on a Combination of Integrated Factors SOM level Soil texture Residue/tillage Soil-test extractable sulfur Plant tissue test level Soil temperature and moisture

25 Considerations for Making S Application If fall rain, winter snow, spring season rainfall is above normal, about 10 lbs S as sulfate, would be needed as a preventive measure Band application (2x2) is recommended, but broadcast works well with adequate rainfall When soil available S tests low to medium, it is a good practice to verify suspected deficiency with a plant tissue test

26 Considerations for Making S Application Critical tissue S levels reported often range between 0.10 to 0.21% S (Jones et al., 1990; Dick et al., 2008; Fernández, 2012) Leaf S concentrations below 0.21%, however, have not always been indicative of S response, for example Reneau and Hawkins (1980) and Stecker et al. (1995)

27 Considerations for Making S Application For confirmed S deficiencies, on fine-textured soils apply about 15 lb S/ac and on coarsetextured soils 25 lb S/ac Consult with your Agricultural Extension Service for the best recommendation avid_franzen/

28 Leaf Sampling To sample leaves at the R stage, take corn leaf opposite and below the corn ear from plants where S deficiency is suspected Beyond the 4-leaf (V-4) stage, take the youngest fully collared leaf from15 to 20 plants At early growth, up to V4, take whole plant cut about half inch above soil from at least 15 plants

29 ALSO REMEMBER Soils testing low for sulfate-s concentrations do not reliably predict crop response Symptoms of S deficiency usually occur randomly across fields Consider readily available forms of S (sulfates) as your source of short- to mid-term S supply Consult with your Agricultural Extension Service for the best recommendation
