“…By improving soil structure, inputs of PMS and DCM also create soil conditions (aeration and moisture) favorable for the growth of microorganisms and for an increase in their biological activities, like those measured in this study (Tables 3 and 4). These results corroborate observations from other studies, which found that adding PMS increased MBC (Chantigny et al, 2000; Gagnon et al, 2001). Overall, the effects of DCM applications on N mineralization rates and microbial respiration were of lesser magnitude than those of PMS additions on both soils.…”

“…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.

“…The percentage of macroaggregate (>0.25mm) ranged from 32 to 36% (Table 3) with no significant difference among crop rotations or N sources. Previous studies with organic amendments have reported that soil structural changes may be short‐lived (Gagnon et al, 2001; Grandy et al, 2002). A study conducted by Angers et al (1999) on a coarse‐ to medium‐textured soil reported that crop management induced changes on soil aggregate stability may be masked by temporal variation associated with climatic conditions.…”

Th is study has assessed rotation systems and N sources to mitigate potato yield and soil organic matter decline in Prince Edward Island (PEI), Canada. Th ree-year potato rotation systems were initiated in 2006: continuous potato (CP); potato-barley (Hordeum vulgare L.) underseeded with red clover (Trifolium pratense L.)-red clover (PBR); and potato-barley-sorghum sudan grass ([Sorghum bicolor L.) used as green manure])/winter rape (Brassica napus subsp. rapifera) (PBSW); and potato-barley-canola ([Brassica napus susbsp. napus] used as green manure)/winter rape (PBCW). Th ree diff erent N sources (mineral N fertilizer, liquid hog manure, and lobster fl ake) were applied in a split-plot fashion during the potato phase. Potatoes were grown in 2006, 2009, 2012, and again in 2013 to evaluate residual eff ects. In 2012, total N or total C in the whole soil, in particulate organic matter or in the slurry fractions were not aff ected by N sources or rotation systems. Th e PBSW and PBCW rotations generated signifi cantly higher potato yields in 2009 and 2013, whereas the CP rotation produced signifi cantly lower potato yields in 2 of 4 yr. Th e addition of lobster fl ake suppressed yield compared with other N sources in 3 of 4 yr. Th e PBR rotation, which is common in PEI can increase nitrate losses over winter. Alternatively, the PBSW and PBCW rotations may represent a good substitute to the PBR rotation as they can increase potato yield while minimizing nitrate losses.Agriculture and Agri-Food Canada, Crops and Livestock Research Centre,

“…3). Actinomycetes in a microbial community increase in number in late stages after other microorganisms consume the easily degradable compounds; then after actinomycetes start to utilize more stable compounds (Gagnon et al, 2001). However, total counts of actinomycetes were markedly increased compared with most counts of the earlier periods.…”

PPLICATION of organic amendments to soil is an important …….management strategy for enhancing soil fertility and microorganisms. A pot experiment was conducted under greenhouse conditions to investigate the effect of compost and compost tea(CT), mineral fertilization only complete (N 100) and half (N 50) recommended doses of nitrogen or combined with two kinds of compost tea (according to extract methods) molasses compost tea (CT1) and molasses compost tea+ ammonium sulphate (CT2) with three application ratios (v:v) (1:25, 1:50 and 1:75) on NPK uptake of leaf and root of radish (Raphanus sativus), soil nutrient status after harvest, and soil microbial populations. Application of CT1 showed that N uptake of radish leaf was about 30.1% higher than that of CT2. CT1 compost tea also increased P and K uptake by 12.6 and 51.5%, respectively, compared with CT2 application. At the end of experiment, soil N, P and K contents were greater in compost amended soil,whereas N uptake of radish leafand root showed only a significant positive correlation with soil N content in the CT2 + N treatments. The populations of the different microorganisms were greater in CT treatment, and increased with time as well. However, it was found that there was a significant negative correlation between leaf and root N uptake of radish and population of anaerobic N 2 fixing bacteria in soil after harvest.
