EXECUTIVE SUMMARY
This project looked at the use of compost as an amendment to Alderwood series soil to
increase water-holding capacity and other soil physical properties, as well as the effect of that
treatment on nutrients and other constituents in runoff. At the University of Washington, four 8 ft.
x 32 ft. beds were earlier constructed out of plywood lined with plastic and filled with Alderwood
subsoil or mixtures of soil and compost. These beds were located at the College of Forest
Resources Center for Urban Horticulture at the University of Washington. Two additional study
installation, one control and one compost-amended, were also installed at two local schools.
Samples were taken over the period from December 6, 1997 to June 26, 1998. Compost
amendment had the following effects on physical water properties:
* Water-holding capacity was increased by 46% with a 2:1 compost:soil amendment.
Water chemistry (total P, soluble-reactive P, ammonium, nitrite and nitrate-N and total N)
were measured for a series of sampling periods. For the overall study, the following results were
observed:
 Runoff from the compost-amended soil had higher P and N of all species compared to the
Alderwood soil that did not receive compost amendment.

INTRODUCTION AND PROJECT OVERVIEW
The College of Forest Resources (CFR) has examined the effectiveness of using compost as a
soil amendment to increase surface water infiltration to reduce the quantity and/or intensity of
surface and subsurface runoff from land development projects. In addition, runoff was evaluated
for dissolved nutrients and other constituents. Currently, due to the wide distribution and inherent
stability of till soils in the region, most residential housing developments are sited on the
Alderwood soil series, which is characterized by a compacted subsurface layer that restricts
vertical water flow. When disturbed (and particularly when disturbed with cut and fill techniques
as with residential or commercial development), uneven water flow patterns develop due to
restricted permeability. This horizontal flow of water on the surface and subsurface contributes to
excessive overland flow, especially during storm events, and transport of dissolved and suspended
particulates to surface waters.
Research has demonstrated compost's effectiveness in improving the soil physical properties
of porosity, continuity of macropores, and water holding capacity which directly influence soilwater relationships. It is clear that compost's chemical properties can also be valuable in some
cases, such as in complexing potentially harmful trace metals including copper, lead, and zinc.
Under this premise, the CFR examined the effectiveness of using compost to increase stormwater
infiltration and water holding capacity of these glacial till soils.
The CFR utilized the existing Urban Water Resource Center (UWRC ) project site at the
University of Washington's Center for Urban Horticulture (CUH) for conducting the study. The
CFR utilized the UWRC design of large plywood beds for containing soil and soil-compost
mixes. Additional sites of a similar design were also constructed at Timbercrest and Woodmoor
public schools in cooperation with the Woodinville Water District.
The following paper describes the site, methods, results, and potential implications of these
studies.
SITE, METHODS AND MATERIALS
Site Description and Construction
What was done. The CFR utilized the existing site and associated facilities at the University
of Washington CUH. The system includes two different (different sites) Alderwood till soils that
were transported to the site, and several mixtures of the till soils and compost mixtures readily
available in the Seattle area. Two plots each of till-only soil and 2:1 mixtures of soil:compost
were studied. The mixture rates were identical for the Timbercrest and Woodmoor sites.

The soil and compost for this study was mixed on an asphalt surface with a bucket loader and
hauled and dumped into the plot bays. A system of collection buckets to allow sampling of runoff
at intervals ranging from 15 minutes to longer was installed as well.
Soil and Compost Analysis
Soil and soil/compost mixture samples were taken 1 month after the initiation of the study and
analyzed by the CFR analytical labs for the following parameters:
1) total C,
2) total N,
6) bulk density,
7) particle density,
3) gravimetric water holding capacity (field capacity) moisture,
4) volumetric water holding capacity (field capacity) moisture,
5) total porosity,
8) particle size analysis, and
9) soil structure.
Total C and N were determined using an automated CHN analyzer since they were considered
to be the primary measures of soil productivity in these soils. Bulk density was estimated using a
coring device of known volume (bulk density soil sampler). The core was removed, oven dried,
and weighed. Bulk density was calculated as the oven dry weight divided by the core volume.
Particle density was determined by using a gravimetric displacement. A known weight of soil or
soil/compost mixture was placed in a volumetric flask containing water. The volume of
displacement was measured and Particle density calculated by dividing the oven dry weight by
displaced volume.
Gravimetric water holding capacity was determined using a soil column extraction method
that approximates field capacity by drawing air downward through a soil column. Soil or
soil/compost mixture was placed into 50 ml syringe tubes and tapped down (not compressed
directly) to achieve the same bulk density as the field bulk density measured with coring devices.
The column was saturated by drawing 50 ml of water through the soil column, then brought to
approximate field capacity by drawing 50 ml of air through the soil or soil/compost column.
Volumetric water holding capacity was calculated by multiplying gravimetric field capacity by
the bulk density. Total porosity was calculated by using the following function:

total porosity = 1-
bulk density
( particle density )
x 100%

(eq. 1)
Particle size distribution was determined both by sieve analysis and sedimentation analysis for
particles less than 0.5 mm in size. Due to the light nature of the organic matter amendment,
particle size analysis was sometimes difficult, and possibly slightly inaccurate. Soil structure was
determined using the feel method and comparing soil and soil/compost mixture samples to known
structures.
Plot Establishment
Plots were planted to a commercial turfgrass mixture during the Spring, 1994 season for the
Urban Horticulture sites and in the fall of 1997 for the Timbercrest and Woodmoor sites.
Fertilizer was added to all plots during plot establishment (16-4-8 N-P2O5-K2O) broadcast spread
over the study bays at the rate recommended on the product label (0.005 lb fertilizer/ft2). The
initial application resulted in an application of 0.023 lb of elemental P as orthophosphate per plot
or 0.000087 lb P/ft2. This resulted in an application of 0.20 lb of elemental N as ammonium and
nitrate (undetermined distribution) per plot or 0.00080 lb N/ft2.
Runoff Characterization and Collection
Runoff amounts and rates were measured by use of tipping bucket type devices attached to an
electronic recorder. Each tip of the bucket was calibrated for each site and checked on a regular
basis to give rates of surface and subsurface runoff from all plots.

There were problems with sampling at all sites. At the Timbercrest site, the very high water
table and the pressure on the sealed container that was supposed to exclude surface water from
entering the collector box, the tipping buckets did not function properly. Thus, they were removed
and collection bottles were substituted for them that did not record flow vs. time. Problems were
not as severe at the Woodmoor site, and samples were collected vs. time for the duration of the
study. At the UW site, tipping buckets were shifted and did not record during the last two time
periods.
All sample collections could not be made.
Runoff Analysis
Runoff was analyzed by the CFR analytical laboratory for the following chemical species:
1) Soluble-reactive P (PO4-P),
2) Acid-hydrolyzeable phosphorus (Hydr P)
3) total Phosphorus (TOT-P),
4) ammonium nitrogen (NH4-N)
5) soluble nitrogen (NO2-N)
6) soluble nitrogen (NO3-N)
7) total nitrogen (NO3-N)
8) chloride and sulfate

RESULTS AND DISCUSSION
Soil and Compost Analysis
The total C, total N, bulk density, particle density, gravimetric water holding capacity (field
capacity) moisture, volumetric water holding capacity (field capacity) moisture, total porosity,
particle size analysis, and soil structure of soil and soil/compost mixtures is given in Table R-1
and Appendix D. Results show large changes in the chemistry and physical properties of the
soil/compost mixtures due to the compost amendment.
The terminology used in industry and science for compost and soil properties is somewhat
inconsistent, so it will be explained quickly how calculations were made. First, percentages can be
given as % by weight or % by volume. In this report, percent by weight uses an oven-dried basis
for calculation. Volumes can change depending on handling, storage, moisture content and other
factors. As a final note the density (volume per unit weight) for compost is usually much lower
(i.e. 0.2-0.3 g/cm3) than for soil (i.e. 1.0-1.4 g/cm3), so a weight percent change from compost
amendment will usually be much lower than a volume unit change, and moisture capacity based
on volume may be much different than moisture capacity based on weight.
Total C and organic matter was enhanced, increasing from 0.1-0.4% C to about 1.1-5.2% C by
weight with the compost amendment. Total N was also enhanced, increasing from 0.02-0.08% to
about 0.06-0.35% with the compost amendment. Gravimetric field moisture capacity increased
significantly from 24% to 35% with the compost amendment. Volumetric field moisture capacity
was also increased from 46 to 50% by the addition of compost.
Total porosity was increased from 41 to 48%. Bulk density was decreased from about 1.7 to
1.1 g/cm3. Particle density was decreased from about 2.5 to 2.1 g/cm3. Particle size analysis was
not greatly affected by the compost amendment. Soil structure, which is not a quantitative
property, was also not greatly affected by compost amendment.
Thus, there was a generally beneficial effect of the compost amendment in regards to nutrient
content as well as soil physical properties known to affect water relations in soils.

Caveats. This study utilized a subsurface tipping bucket design to sample water flow vs. time
for rainfall and surface and subsurface flow. As pointed out earlier, the
Water Chemistry
Caveats. We believe it is important to start with a cautionary note in terms of directly
comparing the concentrations of unamended with compost-amended plots in terms of the practical
use of compost vs. inorganic fertilizers in a field situation to achieve a desired turf. If there is a
minimum standard of aesthetic for the turf for a given area of land, whether it is compostamended or not, it is apparent from the visual appeal of the sites that more inorganic fertilizer will
be applied in the unamended vs. the compost-amended soils to achieve the same visual appeal.
Following planting, compost-amended plots developed a dark green color quickly, and achieved
100% coverage much more rapidly than unamended plots. At the end of this study, the compostamended sites were much better aesthetically, with a darker green color and no bare spots. No soil
can be seen through the grass. There are many bare spots with exposed soil in the plots that did
not receive compost amendment. The rates of growth of turf were also greater even after a
considerable period of time. The visual appeal of the compost-amended sites was much greater
during the duration of the study, although all sites did grow grass.
However, when inorganic fertilizer was applied initially, it was applied equally at all sites
since there was nothing but bare ground initially, and in addition, the standard of aesthetic is not
quantitative. Over time, however, it was apparent that it would be very difficult to achieve the
same visual appeal with inorganic fertilizer applied to soil only in comparison to the compostamended soil.
Overall range of solution concentrations. The average solution analysis concentrations of
samples are given Table R-2, with QA/QC data given in Appendix A, each individual sample
analyzed given in Appendix B, and averages, number of samples and standard deviations in
Appendix C. It is obvious that there is a great deal of variation in solution chemistry in runoff
from these results. For instance, the average total P (TP) concentration for all samples analyzed
was 2.76 mg/l while the minimum P was 0.00 and the maximum 125 mg/l (Appendix B). This
represents a high degree of variation in concentration. This is not wholly unexpected in a system
such as the one studied with treatments ranging from surface runoff with high water flow in a very
infertile, unfertilized glacial till soil to surface and subsurface runoff in soils freshly fertilized with
soluble NPK fertilizers. Basic conclusions are as follows:

page 11
The high amount of variation seen in these results makes drawing specific and consistent
conclusions with statistical significance difficult.
The soluble-reactive P (PO4-P) concentration for all samples analyzed was 2.29 mg/l while
the minimum P was 0.00 and the maximum 125 mg/l (Appendix B), indicating that the PO4-P
was generally most of the total for all samples. The average PO4-P concentration measured is
considerably above the Water Quality recommendations for freshwater according to WAC 173201 (1992), which is 0.100 for flowing water not discharging directly into a lake or impoundment.
There is no standard for total phosphorus or nitrate.
The ammonium-N concentration averaged 6.55 mg/l while the minimum ammonium-N was
0.00 and the maximum 360 mg/l (Appendix B). The variation of solution ammonium-N was thus
quite high. The NO3-N concentration averaged 2.61 mg/l while the minimum NO3-N was 0.00
and the maximum 74 mg/l (Appendix B). The total-N concentration averaged 11.7 mg/l while the
minimum total-N was 0.20 and the maximum 479 mg/l (Appendix B). Thus, the variation of
solution NO3-N and total-N was also quite high.
Averages-comparison of amended vs. unamended. For overall averages, there was a large
difference between runoff collected from compost-amended and unamended plots.
For instance, runoff solutions had PO4-P concentration averages of 0.30 mg/l in unamended
vs. 4.99 mg/l for the compost-amended plots, indicating that overall, the amended sites had 17
times as much PO4-P. Runoff solutions had Hydr-P concentration averages of 0.40 mg/l in
unamended vs. 2.45 mg/l for the compost-amended plots, indicating that overall, the amended
sites had 6 times as much Hydr-P. Runoff solutions had total-P concentration averages of 0.56
mg/l in unamended vs. 5.80 mg/l for the compost-amended plots, indicating that overall, the
amended sites had 10 times as much total P.
Runoff solutions had NH4-N concentration averages of 0.46 mg/l in unamended vs. 15 mg/l
for the compost-amended plots, indicating that overall, the amended sites had 32 times as much
NH4-N. Runoff solutions had NO3-N concentration averages of 1.45 mg/l in unamended vs. 4.34
mg/l for the compost-amended plots, indicating that overall, the amended sites had 3 times as
much NO3-N. Runoff solutions had total-N concentration averages of 2.22 mg/l in unamended vs.
24.59 mg/l for the compost-amended plots, indicating that overall, the amended sites had 11 times
as much total N.

Water and nutrient fluxes. The fluxes of water and nutrients were calculated for each
sampling period. Results are included in Appendix E tables. There were differences in fluxes
between treatments. For instance, The UW sites had water deficits during the study period of 127,
128 , 96 and 150 mm for plots 1, 2, 5 and 6, respectively. Plots 1 and 5 are till-only, while 2 and 6
are compost amended. This represents % deficits of 25, 25, 19 and 29 %, respectively. The
Woodmoor site had deficits of 81 and 160 mm for the till-only and compost amended sites,
representing % deficits of 16 and 31%, respectively. The Timbercrest site had overflows, so
deficits could not be calculated. These results appear to indicate that compost can hold more water
available for evapotranspiration.
For PO4-P, the fluxes were much higher in the compost-amended sites. For instance, in the
UW site, it was estimated that 25 mg PO4-P/m2 were input in precipitation, while 20, 108, 22 and
578 mg PO4-P/m2 were measured in water leaving the plots in Plots 1, 2, 5 and 6 during the study
period. For the Woodmoor site, 510 mg PO4-P/m2 were estimated to have been input with rainfall,
but 15.1 and 579 mg PO4-P/m2 were measured in runoff from the sites. Fluxes of phosphate-P
were not very reliable for the Timbercrest site due to the overflow of collection buckets.
For total-P, the fluxes were much higher in the compost-amended sites. For instance, in the
UW site, it was estimated that 27.2 mg total-P/m2 were input in precipitation, while 9.2, 204, 74
and 1171 mg total-P/m2 were measured in water leaving the plots in Plots 1, 2, 5 and 6 during the
study period. For the Woodmoor site, 0.0 mg PO4-P/m2 were estimated to have been input with

page 14
rainfall, but 27.6 and 1445 mg PO4-P/m2 were measured in runoff from the sites. Fluxes of total-P
were not very reliable for the Timbercrest site due to the overflow of collection buckets.
For NO3-N, the fluxes were variable in the compost-amended sites. For instance, in the UW
site, it was estimated that 46 mg NO3-N/m2 were input in precipitation, while 3.7, 135, 62 and
19.3 mg NO3-N/m2 were measured in water leaving the plots in Plots 1, 2, 5 and 6 during the
study period. For the Woodmoor site, 8.2 mg NO3-N/m2 were estimated to have been input with
rainfall, but 27.3 and 30.4 mg NO3-N/m2 were measured in runoff from the sites. Fluxes of NO3N were not very reliable for the Timbercrest site due to the overflow of collection buckets.
For total-N, the fluxes were much higher in the compost-amended sites. For instance, in the
UW site, it was estimated that 549 mg total -N/m2 were input in precipitation, while 506, 1445,
1088 and 928 mg total -N/m2 were measured in water leaving the plots in Plots 1, 2, 5 and 6
during the study period. For the Woodmoor site, 510 mg total-N/m2 were estimated to have been
input with rainfall, but 898 and 20,578 mg total-N/m2 were measured in runoff from the sites.
Fluxes of total-N were not very reliable for the Timbercrest site due to the overflow of collection
buckets.
SUMMARY AND CONCLUSIONS
Summary of Results
There was a substantial difference in appearance of sites. There was insufficient grass growth
in unamended sites, even following an establishment fertilization. The compost-fertilized site was
very attractive and needed no fertilization. In fact, the initial establishment fertilization probably
wasn’t necessary either based on studies of turfgrass growth in compost-amended soils without
inorganic fertilization at the University of Washington on similar soils. The limited results
available from these studies point out the necessity of conducting a field study that incorporates
sufficient repetitions, time, and fertilization regimes that establish similar turfgrass.
The results of these studies clearly show that compost amendment alters soil properties known
to affect water relations of soils, including the water holding capacity, porosity, bulk density, and
structure, as well as increasing soil C and N, and probably other nutrients as well. The
mobilization of these constituents probably led to observed increases in P and N species in runoff.
