J. Ippolito
We have studied the beneficial use ofLittleton/E g)ee,ood (I.JE) biosolids since 1982 at
West Bennett, since 1988 at Kiowa, since 1993 at N onh =en, and since 1999 at Byers. We
lost one of the West Bennett sites to development and research at the Kiowa location is less
critical now that the joint city councils have purchased the Byers property. We will present the
proposed research and associated budget separately for all four locations and then present the
total budget for our proposed research.
IV. Bennett Study Sites
A. West Beonett
We established sites A ?."l B at West Bennett in 1982 and in 1983, respectively. Our
cooperating farmer, Jim Hazlett has sold site B for homesite deve]opmeot. We will continue
using West A since it represents the last of our original, long-term sit es . Since we follow a fallow
system for our dryland wheat study, we would use thls site every other year. We established this
site again in summer of2000 and will haxvcst the wheat in summer 2001 . This site will remain in
fallow from July 2001 until late July or early August 2002 when we will again apply l.JE
biosolids.
B. Nortb Bennett
W e init ia ted th e North Bennett ex perimental location to re ?lace the East Bennett plots
that w e Jos t in 19 9 3. Our former cooperating farmer a t East Bennett, Kevin Helzer decided to
grow irrig a•~d c ro ps o n our s tudy si te s :n 199 3. We al so cha.'lged the exp .crimental approach at
Nonh Be nn et t to focus on determining the N equivalency ofL/E b iosolids associated with
repea ted appl ic .. t i ons in a drylar.d w h eat summer-fallow ag:roec osyste m. We will complete
harvest soil, grain, a.'ld straw sampling and ana1yses as we have in the past .
C. Objective• for the Bennett study sites (West a11d North Bennett)
The objectives o f the Bennett study are :
I. To determine the continuing effects, at West B ennett s ite A, of various
•

sewage-biosolids rates on tlryland wheat including grain yield, protein
content, potential income and the N, P, K concentrations after one
application ofliquid biosolids (1982) plus nine additions of dried biosolids
(1984, 1986, 1988, 1990, 1992, 1994, 1996, 1998, 2000). The next
scheduled biosolids application is in 2002.
2 . To quantify the N equivalency of repeated biosolids application under field
conditions compared with commercial N fertil izer at our North Bennett
plots.
3. To srudy the long-tenn effects of UE biosolids on uptake of Cd, Cr, Cu,
Ni, Pb, Mo, and Zn by wheat .
4 . To study the long-tenn effects ofL/E 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.l composite of all replications for each rate fo r
grain analyses. This gives three grain samples each for both North and
West Bennett. We also will composite separately the 0-20 and 20-60-cm
soil samples from the same plots as the grain samples. This will provide
us a total of six s:i.mples to analyze for each site.
5 . To observe long-term changes in the water sorptivity of the soil with
continued LIE biosolids aoditions at North Bennett.
6. To determine the accumulated N01-N level s to a depth of 180 cm (6 feet)
associated with repeated application of various N fertilizer or sewage
biosolids at our West Bennett site A and North Bennett plots ..
D . Bennett study sites budgets (See Table 1 on the next page) .

V. Kiow::i Study Site
A. Introduction
We will continue to take water samples from the four wells on a quanerly or annual basis.
Quarterly samples would include analyses for total N, NO3-N, NH,-, P, K, Ag, Al, As, Cd, Cu,
Fe, Pb, Hg, Mo, Ni, Se, and Zn. We also will analyze the annual samples for endrin, lindane,
methoxychlor, toxaphene, 2,4-D, and 2,4,S-T. The objective of this study is continued monitoring
of groundwatCT in four wells for total N, NO,-N, NH.-N, P, K, Ag, Al, As, Cd, Cu, Fe, Pb , Hg,
Mo, Ni, Se, Zn, endrin, l:ndane , methoxychlor, tmcaphene, 2,4-D, and 2,4,5-T following the

Vl . Byers Study Site
A. Introduction
Wi1h th e development of the Byers biosolids-application location by UE, we are
developing some practical, never-done-before research. No-till and minimum tillage management
is increasing in popularity in e:istern Colorado because it improves water conservation and allows
more intensive cropping. Biosolids application could enhance the benefits of no-till or minimum
tillage by improving soil cover and soil physical charac1eristics when surface applied. The
biosolids could work in concert with crop residues to allow farmers to meet the 30¾ soil
coverage re quired by the Natural Resource Conservation Service to comply with conservation
programs.
Biosolids application cou ld initially supply soil cover until adequate crop residue can
accumu late . Continued additions may even provide production and ec .i nomic advantages.
Farmers may eventually us e biosolids as an integral part of a conservation program. To date, we
have applied b iosolids for the second-year rotation to pl ots growing wheat, com, and sunflowers.
B. Objectives
Our objectives at the Byers site arc :
l. To determine if increasing biosolids application from once every two years
to two out o f three years or four out of five years is a feasible management
alternative.
2 . To determine ifbiosolids application will improve surface sorptivity
(water infiltration) in no-till or minimum tillage systems that include row
crops und er dryland conditions.
3. To determine ifbiosolids behave like rrop residues in terms of moisl'1re
storage and crop production. Available:• water storage and crop yields arc
the propenies of greatest interest. '
..! To determine the effects ofbiosolids application at the agronomic rate
compared with commercial N fertilizer in three cropping systems on so il
and grain accumulation of plant nut · ents and trace clements limited by the
Colorado Department of Public Health and Environment in their biosolids-
app!ication regulations .

C. Procedure~
Treatments :
1. Three crop rotations:
a. Wheat-fallow (typical rotati on)
b. Wheat-com-fallow
c. Wheat-wheat-com-sunflowers-fallow (based on managing
Farmer's interest)
2. Two biosol ids/fertilizer treatments:
a. Biosolids application to supply N recommended for the
measured soil NO1-N (e.g., the agronomic rate).
b. Ccmmercial N fertilizer at the agronomic nte.
D . Experimental desieu
We will use two blocks (replications) oi each treatment arranged in a split-plot design .
The main plots will consist of the cropping rotations whlle we will split each main plot to
accommodate biosolids application on half the plot and commercial fenilizer addition on the
other half.
All phases of each rotation will be present each year to allow assessment of all soil and
crop responses each year. This would require a total of20 main plots and 40 split plots (2
replications, IO cropping rotations, 2 biosolids/fertilizer treatment splits).
Each main plot will be 0 .8 km (0.5 miles) long by 30 m (1 00 feet) wide . Each
b ioso lids/fertilizer split would , therefore, be 15 m (50 feet) wide.
E. Measurements
We will complete the following measurements or analyses.

BACKGROUND, ANALYSIS, AND ALTERNATIVES IDENTIFIED
Since 1 982, the Littleton/Englewood Wastewater Treatment Plant (L/E WWTP) in cooperation with Colorac'o
Sta te University (CSU) Department of Soll and C rop Sciences has success fully conducted a continuous research
program to observe the long-term effects of the application of biosollds for dryland wheat /arming. The research
has provided long-te rm research data and a so und basis of kn owledge of the biosolids produced by the L/E
It\ VTP and the e nvi ronmental Impacts of the pro duct. The information has been used extensively as a public
relation s too l. as well.
• d ditionall y, the L/E WWTP/CSU research project ha< been i nstrumental in establishing th e bas is for biosolids
•
beneficial use for the growth of dryland wheat crops in the arid western states and in Australia. The long-term
res earch demo nstrates that the bene ficia l use of wastewater biosolids is an environmentally safe, economically
beneficial. and agriculturally sound practice for ,·ecycling and conserving a valuable resource. The research has
resul ted in thirteen reference journal articles ,nd book chapters, twenty-th ree technical papers, numerous
bulletins and reports, one doctoral thesis (another In progress) and two masters thesis . The re search has
benefited not only western states farming communi ties, b ut also b iosolids researchers, re gulators, generators,
