“…Application of FDS, CDS, or N fertilizer significantly increased soil macroaggregates (>2 mm) and the mean-weight diameter of aggregates, compared to the unamended, unfertilized control (Table 2; contrast 1). As in this study, Chantigny et al [28] and Bipfubusa et al [29] indicated that paper sludges applications rapidly increased soil macroaggregates proportions and stability. Compared to the control, the application of FDS or CDS contributed to the formation of larger macroaggregates (>5 mm and 2-5 mm) probably due to the increase of organic binding agents that form macroaggregates such as polysaccharides, microbial products, phenolic substances, and humic substances [10,30] Surprisingly, N fertilizer also increased the proportion of soil macroaggregates (>2 mm) Table 3: Residual effects of applications of fresh and composted paper sludges, and N fertilizer on soil bulk density, nitrogen and carbon contents, C/N ratio, and C (Mg ha −1 ) at 0-10-cm soil layer in 2004.…”

In this 5-yr study, application frequency of fresh (FDS) and composted (CDS) paper sludges was evaluated on soil properties and silage corn (Zea maysL.) and barley (Hordeum vulgareL.) yields and N uptake by comparing one application (2000) with repeated applications (2000, 2001, 2002). Treatments consisted of a control with neither amendment nor N fertilizer, a recommended N rate for corn (160 kg N ha−1) and barley (90 kg N ha−1), and FDS and CDS at a rate of 40 Mg ha−1on wet basis with or without reduced N fertilizer (120 kg N ha−1) on corn. Compared to the control, the FDS or CDS applications significantly increased the proportions of soil larger macroaggregates (>2 mm) and the mean-weight diameter (MWD) of aggregates, regardless their application frequency. Single or three yrs additions of FDS or CDS produced, on average, an increase of 25 to 31% of the soil C and N contents compared to the control and the recommended N fertilizer treatment (160 kg N ha−1). In the first year of their application, the FDS or CDS with or without supplemental N fertilizer (120 kg N ha−1) reduced silage corn and N uptake, compared to the control probably due to N immobilization. However, silage corn yields were increased in the following years with one application or with repeated application of FDS or CDS. Results show that benefits on soil properties and crop yields of single application of FDS and CDS were similar to those of the triple applications and were still noticeable a few years following the last application.

“…The three other treatments had similar N concentrations across all size classes. Upon aggregate breakdown, occluded N and C within aggregates are mineralized into forms available for plants and microorganisms (Bipfubusa et al, 2005). Considering that N content in all aggregate size classes was similar in the Bio‐20 treatment and the control, it appears that the increase in the soil organic N pool from the Bio‐20 treatment was either insufficient to generate a detectable difference or that it was depleted via mineralization in the subsequent 4 yr.…”

Biosolids Increase Soil Aggregation and Protection of Soil Carbon Five Years after Application on a Crested Wheatgrass Pasture

et al. 2009

Biosolids application to rangelands and pastures recycles nutrients and organic matter back to soils. The effects of biosolids (20 and 60 dry Mg ha(-)(1)) and N+P fertilizer on soil aggregate stability, bulk density, aeration porosity, and total C and N of stable aggregates were evaluated 4 and 5 yr after surface application to a crested wheatgrass [Agropyron cristatum (L.) Gaertn.] pasture in the southern interior of British Columbia (BC). The experiment was established in 2001 in a randomized complete block design with four replications. The 60 Mg ha(-1) biosolids treatment (Bio 60) had a greater aggregate mean weight diameter (MWD) and proportion of water-stable soil aggregates > 1 mm relative to the control and fertilizer treatments. Temporal variation in aggregate stability was attributed to seasonal variations in soil water content. Surface application of 60 Mg ha(-1) of biosolids increased C concentrations within water-stable aggregates relative to the control from 29 to 104, 24 to 79, and 12 to 38 g kg(-1) for the 2 to 6, 1 to 2, and 0.25 to 1 mm size fractions, respectively. The concentration of N within aggregates increased in similar proportions to C. Neither soil bulk density, nor aeration porosity were affected by biosolids application. Increased aggregation and the accumulation of soil C within aggregates following biosolids application creates a potential for better soil C storage, soil water retention, nutrient availability, and ultimately the overall health of semiarid perennial pastures.

“…Our results show an increase in soil macroaggregate sizes (Σ > 0.25 mm) and in soil structural stability as indicated by the MWD of water‐stable aggregates following repeated applications of PMS and DCM, compared to the control and MF treatments. A number of studies have also shown an increase in macroaggregates and in the MWD of water‐stable aggregates following PMS applications (Nemati et al, 2000; Gagnon et al, 2001; Bipfubusa et al,.2005, 2008; N'Dayegamiye, 2006).…”

Th e contribution of organic wastes to crop yields and soil fertility may be infl uenced by their composition and the soil type. Th is 6-yr study (2001)(2002)(2003)(2004)(2005)(2006) evaluated the eff ects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha -1 ), dairy cattle manure (DCM) (36 Mg ha -1 ) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on soil properties and corn (Zea mays L.), barley (Hordeum vulgaris L.), and soybean (Glycine max L. Merr.) yields in a clay loam and sandy loam. Th e applications of PMS and DCM increased mostly N mineralization and crop yields in the sandy loam than in the clay loam. However, increases of soil C contents, water-stable aggregates and MWD following their application were higher in the clay loam than in the sandy loam. Th e DCM eff ects on the soil property changes were of less magnitude than those of PMS. Except in the fi rst year, the PMS applications at rates of 36 and 54 Mg ha -1 without NPK, and PMS applied at a rate of 18 Mg ha -1 with 60% NPK, produced highest crop yields in both soils and were comparable to those obtained with MF. Th e increase in yield following DCM additions (36 Mg ha -1 ) was lower than that obtained with PMS. Annual MF applications increased crop yields in both soil without signifi cant changes on soil properties. Th e benefi ts of PMS and DCM on soil properties and crop yields varied depending on organic wastes and soil type.
