Since we fo ll ow a fa ll ow sys tem fo r our dry land wheat srud y, we woul d •tse this site every othe r yea r. We will establ ish this site again in summer of2004 and will hru ,est the wheat in sum •.ner 1005 . This site will remain in fallow from Ju ly 2003 until late July or early .-'.ugust 2004 when we will agai n apply LIE biosolids. B.

Objecti ves fo r the Bennett srudy sites (Wes t and North Bennett) The objectives of the Bennett srud y are : I. To detennine the continuin g effects. at West Bennett site A, of various sewage-biosol ids rates on dry land wheat including grai n yield, protein co nt ent, potential income and the N, P, K conce ntratio ns after one ap plicatio n of liquid biosol ids (1982) plus 11 additio ns of dried bioso li ds (198-1 , 1986, 198 8, 1990 , 1992, 1994, 1996, 1998 , "000, 200", 2004) wi th the next sc hed uled biosolids applicatio n is in 20 04. 2. To quantify the N equival ency of repeated biosolids appl ication under field conditio ns co mpared with commercial N fertilizer at our No rth Bennett plots . 3. To srudy the long-tenn effects of UE biosolids on soil acc umul ati on and whe~t uptai-.e of Ag, Ba, Cd. Cr, Cu. Mn, Ni, Pb , Mo, and Zn. 4. To srudy the long-term effects of UE biosolids on As, Hg, and Se levels in soil and grain in the 0 . 2, and 5 dry tons/acre plots for the North Bennett site and on the 0 , 3, and 6 dry tons/acre plots for West Bennett site A. Samples will consist of a co mposite of all replications for each rate for gmi n analyses . Thi s gives three grain sam ples each for both No rth and West Benne tt . We also wi ll composite separatel y the 0-20 and 20-60-cm soil samples fro m the same pl ots as the grain samples. T:u . wi ll provide us a tota l o f six soil samp le s to anal yze fo r eac h site . 5. To detennine the accumulated NO;-N levels to a dep th of 180 cm (6 feet) associated wi th re peated applicati on of various N fertilize r or sewage 1,,,,so li cis ot our West Bennett site A and No rth Bennett plo ts.

Byers Study Site A. Introduct ion With ,he de vel opment of the LIE Byers bi os olid s-application site , we are de vel opin g some practical , ne ver-done-befo re research . No-till and minimum tillage management is inc reasing in popularity in eastern Colorado because it improves water conserva ti on and allows more intensive cropp in g. Bi osolids appl ic ation could enhance the benefits of no -till or minimum tillage by improving soil cove r an d so il physic,! ct~racteristics when su rface applied. Bioso lids could work in concert with crop residues to ,llow farmers to me et the Natural Resource Conservatio n Servi ce 30% so il coverage requi red to comp ly with co nservatio n programs. Biosolids application cou ld init ially supply soil co ver until adequate cro p resid ue c,n accumulate . Co nt inued additi ons may even provide production and eco nomic advan ta ges. formers may eventua ll y use biosolids as an integra l part of a co nserva tion program . To date , we have app li ed biosolids fo r the fourth-year rota tion to pl ots growin g wheJ t, co m , and sunflowers. B. Objectives Our objectives at the Byers sit e are : l. 3. To determine if increasi ng biosolids ap plicJti on from once every two ye,rs to two out of three years or fo ur out o f five ye ars is a feasib le manageme nt alt ernative. To determine if bioso lids behave like crop resid ues 'n terms of mo ist ure stora ge and crop prod uc tio n. Availab le -water sto rage and crop yiel r'• ,re the properties of greates t interest. To determine the effects of biosol ids app licat ion at the agronomi ~ cate compared with commercia l :,./ fertilize r in three cropping systems on so il and grain accumulation ot'plant nutrients and trJce elements limited by the Co lorado Departme nt o t' Public Hea lt h and En vironment bio so lids- app li cation regulati ons. • • • • • C. Procedures Treatm ents: I. Three crop rotations: a. Wheat-fallow (typic al rotation) b. Wheat-com-fallow c. Wheat-wheat-com-sunflowers-fallow (based on managing Farmer's interest) 2. Bi os olids/fertilizer tre atments : a. Bio so lid s applicat ion to supply N recommended fo r the measured so il NO;-N (e.g., the agronomic rate ). b. Commercial N fertilizer at the agronomic rat e. D. Experime ntal design We will use two blocks (replicatio ns) of each treatment arranged in a split-plot design. The main plots will consist of the cropping rotations. Each main plot will be split to accommodate biosolids application on half the plot and commercial fertilizer addition on the other half. . .\ll phases of each rotation will be present each vear to allow ass ess ment of all ;011 and crop responses each year . This requires a total of:!O main plots and ~O split plots (:! rep licatio ns , IO cropp ing rotations , biosolids/fertilizer treatment spli ts). Each main plot wi ll be 0.8 km (0.5 mil es) lo ng by 30 m (100 feet ) wid e. Each biosolids/fe rtilizer split would, therefore. be 15 m (50 feet) wide . E. Meas ureme nts We will co mplete the following me as urements or anal yses. Annual grain and biom?~s yields. Complete records on fa ,er in put s. Planc-availab ie co nce~trarions uf NO,-N. P, K. Fe. \,In . Cu , Zn. Na. Cd . Cr. Pb . \,lo. :--ii . Ba. ;\,I n. and . .\g in ;oil before ea c~ crop planting /determined in 0-5 . 5-10. 10-2 0. and :o.;o cm samp les fr om each re;,licated plotl . 4. We will composite 0-5-cm soil samples fo r As, Hg, and Se analyses for each replication before eac h cro p planting. This will give us 14 soil samples to analyze for As, Hg, and Se each year. 5. Deep soil sampling before each cro p planting by hydraulic probe for NOi-N (detennined 0-30, 30-60, 60-90, 90-120, 120-1 50, 150- 180 cm samples, if possible, from each replicated plot). 6. Concentrations of P, K, Fe, Mn, Cu , Zn. Na, Cd, Cr, Pb , Mo, Ni, Ba, Mn, and Ag in grain sampled from each replicated plot. 7. For annual As, Hg , and Se grain anal ys es , we will composite grain samples for each bioso lids or N fertilizer replic:uion for each type of crop . This sche me wi ll provide us wit h eight wheat, four com , and two sunflower san ·les for As, Hg , and Se analyses each year. F.
