VI. Byers Study Site
A. Introduction
With the development of the Byers biosolids-application location by LJE, we are
developing some practical, never-done-before research. No-till and minimum tillage management
i~ incr-..zing in popul:irity in ea.stem Colorado because it improves water conservation and
allows more imensive cropping . Biosolids application could enhanc~ the benefits of no-till or
minimum tillage by improving soil cover and soil physical characteristics when surface appJ;ed.
TI,e biosolids could work in concert with crop residues to allow farmers to meet the 30% soil
covero.ge required by the Natural Resource Consr.-rvation Service to comply with conservation
progiams.
Biosolids application could initially supply soil cover until adequate crop residue can
accumulate. Continued additions may even provide production and economic advantages .
Farmers may evenrually use biosolids as an integral part ofa conservation program . To date, we
have applied biosolids for the first-year rotation to plots gro,ving wheat, com, and sunflowers .
B. Objectives
Our objectives at the Byers site are :
l. To determine if increasing biosolids application from once every two years
to two out of three years or four out oi five years is a feasible management
alternative .
2 . To determine ifbiosolids application will improve surface soil physical
properties in no-till or minimum tillage systems that inch1de row crops
under dryland conditions. Such properties as water sorptivity and bulk
density are Qur prime concerns.
3. To determine ifbiosolids behave like crop residues in terms ofmoisrure
storage and crop production . Available-water storage and crop yields are
die properties of greatest interest.
4. To determine the effects ofbiosolid , application at the agronomic rate
compared with commercial N ferti !i z~r in three cropping s:•stems on soil
and grain accumulation of plant nutrit.nts and trace elements limited by the
Colorado Deparonent of Public Health and Environment in their biosolids-
application regulations ._.
i-, I
C. Procedures
Treatments:
l . TI1ree crop rotations :
a. Wheat-fallow (typical rotation)
b. Wheat-<:om-fallow
c. Wl1eat-wheat-com -s unt1owtrs-fallow (based on managing
Farmer 's interest)
2. Two biosolids/fertilizer treatments :
a. Biosolids application to supply n recommended for the
measured soil NO3-N (e .g ., the agronomic rate) .. -
b. Commerc ial N fertilizer at the agronomic rate .
D. E:tperlmeot:11 design
We will use two blocks (replications) of each treatment arranged in a split-plot design .
The main plots will consist of the cropping rotations while we will split each main plot to
:iccommodate biosolids applicatinn on half the plot and commercial fertilizer addition on the
other hal f.
All phases of ~ch 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(~
repl ications, 10 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
biosolidsi fo rtilizer sp lit would, therefore, be 15 m (50 feet) wide .
E. Measurements
W~ will complete the following measuremenrs or anal yses .
l . Annual grain and biomass yiel ds.
2. Soil water cont ent to !SO cm (6 fee t) at plmting and harves t for
each crop each year.
3. Water sorpt iv ity and bulk densi ty .
4. Complete rec.or~ on costs of herbic ide inputs, etc.

We recomme nd Co uncil approve by Ordinance an Interg overnmental Agre emen t with Colorado Stale Un ivers ity
for the cooperat ive research project on land applicatio n o• sswage bios olids on dryland wheal in lhe amount of
$67 ,085 .
BACKGROUND, ANAL fSIS , AND ALTERNATIVES IDENTIF1i:D
Since 1982 , the Littleton/Englewooa Wastewater Treatment Plant (UE WWTP) in cooperation with Colorado State
University (CSU) Department cl So ll and Crop Sciences has successfully conducted a continuous research
program lo observe the long-term effects of the application of biosolids for dryland wheat farming . The research
has provided long-term research data and a sound bas is of knowledge cl the blosolids produced by l~e UE
WWTP and th e environmental impacts of the product. The info rmatio n has been used extensively as a public
relations tool , as well.
Addtt ionally, the UE WWTP/CSU research project has been instrumental in establi shing the basis for biosol ids
beneficia l use for the growth of dryland wheat crops in 1he arid western states and in Australia. The long-term
research demonstrates that the beneficial use of wastewater biosolids is an environmentally safe , economically
beneficial, and agriculturally sound practice for recyc li ng and conserving a valuable resource . The research ha s
resulted in th irteen reference journal articles and book chapters, twenty-three technical papers , numerous bulletins
and reports , one doctoral thes is (another in progre ss ) and two masters thesis . The research has benefited not
only western states farm ing communities , bu t also bios ol ids researchers, regulators, yene rato rs , app li ers and
other environmental profess ionals in the follow ing ways :
In 1999 the UE WWT P and CSU rece ivad the U.S. EPA Outstanding Research Contributing to Beneficial Use of
Wastewater Sol ids -First Place Nat ional (1 999)
Colorado Stale Un iversi ty has submitted th ,i r proposal for the co operative research project on land application of
sewage biosol ids on dryland wheat. Th e 2 lO ' study includes stud y sites al the Bennett stte , the Kiowa site , and
