“…These observations are in agreement with those of Wu et al (2000), who reported alkaline pH for composts made with sludge and garden residues. Many other authors reported no effect on pH (Bevacqua and Mellano, 1994;Crecchio et al, 2001;Zebarth et al, 1999). However, there are several studies that revealed either an increase of acidic soil (Hue, 1992;Whalen et al, 2000;Baziramakenga et al, 2001;Butler and Muir, 2006;Valarini et al, 2009) or a decrease (Chang et al, 1991), While increasing pH is clearly valuable in terms of improving microelement availability, lowering pH should be limited to avoid enhancing the solubility of toxic elements.…”

A B S T R A C TThe objective of this study was to determine the effects of the application of different doses of compost made with sludge and organic residues from plants on some soil characteristics, growth and yield of sugar beet (Beta vulgaris L.) grown in Moroccan soil having low organic matter. A field experiment was conducted and complete randomized block with four replicates was designed. Treatments consisted of control without any organic amendment and three concentrations of compost (2.5, 5.0 and 7.5 t haG 1 ). Results showed that, in general, application of at least 5 t haG 1 of compost increased soil organic matter along with C rates and other mineral nutrients such as N, P and K. Application of 5 t haG 1 of compost significantly increased sugar beet biomass and recoverable sugar yield. This beneficial effect was reversed with the highest dose of 7.5 t haG 1 .

“…Organic amendments are commonly applied to agricultural soils to provide plant nutrients, to improve soil quality and in some cases to divert these materials from landfills (e.g., Schoenholtz et al 1992;Zebarth et al 1999;Allard and Neilson 1997). However, application of composts and animal wastes to soil can increase greenhouse gas emissions (Cabrera et al 1994;Dendooven et al 1998a;Maag and Winther 1999).…”

. 2003. Interactive effects of composts and liquid pig manure with added nitrate on soil carbon dioxide and nitrous oxide emissions from soil under aerobic and anaerobic conditions. Can. J. Soil Sci. 83: 343-352. The composting process results in immobilization of inorganic N. When high-Ndemanding crops are grown in compost-amended soils, additional N fertilizer is often applied. The combination of elevated nitrate levels from N fertilizer and high C inputs from the compost may result in enhanced greenhouse gas emissions. Hence, the objective of this laboratory incubation study was to characterize CO 2 and N 2 O emissions from a Brookston clay loam soil that has received organic amendments in the presence or absence of added nitrate. The organic amendments included urban yard waste compost (YWC), liquid pig manure + wheat straw compost (PMC), and liquid pig manure (LPM). The nitrate treatments included added nitrate (100 mg KNO 3 -N kg soil -1 ) or no added nitrate. Total CO 2 emissions during aerobic incubation followed the pattern: YWC > LPM > PMC > control (no organic amendments) for both nitrate treatments. Nitrate addition increased CO 2 emissions from the YWC-and LPM-amended soils by 9 and 43%, respectively, but had no significant effect (P < 0.05) on CO 2 emissions from the control or the PMC-amended soil. All organic amendments increased N 2 O emissions compared to the control. When nitrate was added to aerobically incubated LPM-amended soils, N 2 O emissions were increased over seven times; however, N 2 O emissions were decreased by 93% for PMC-amended soils and by 50% for YWC-amended soils. These decreases in N 2 O production occurred when nitrate was added to the YWC and PMC treatments under aerobic conditions but not under anaerobic conditions. Composted liquid pig manure was found to be more environmentally friendly than raw liquid pig manure as it stabilized the manure C and reduced CO 2 and N 2 O emissions compared to the liquid pig manure. . Pour le nitrate, le traitement consistait en l'addition ou pas de nitrate (100 mg de KNO 3 -N par kg de sol). Les dégagements totaux de CO 2 durant l'incubation aérobique suivent la progression YWC > LPM > PMC > témoin (aucun amendement organique) pour les deux traitements au nitrate. L'addition de nitrate augmente les émissions de CO 2 des sols bonifiés avec du YWC et du LPM de 9 % et de 43 % respectivement, sans incidence significative (P < 0,05) sur les émissions de ce gaz par le sol témoin et celui amendé avec du PMC. Tous les amendements organiques augmentent les dégagements de N 2 O comparativement au sol témoin. Quand on ajoute du nitrate au sol amendé avec du LPM, l'incubation aérobique multiplie les émissions de N 2 O par sept, mais ces dernières baissent de 93 % pour le sol bonifié avec du PMC et de 50 % pour celui amendé avec du YMC. Ces baisses surviennent quand le nitrate est ajouté à ces deux derniers types de sol dans des conditions aérobiques mais non anaérobiques. Le compost de lisier est moins dommageable pour l'environnement que le lisier b...

“…Weber et al (2007) reported that the effect of compost application from muanicipal solid waste on PAW was transient, lasting only about one month after application, whereas there was no effect after two or three years. Zebarth et al (1999) showed that poultry and food waste compost increased the water retention capacity of a sandy soil two years after application. Compost produced from organic dairy cattle manure can result in higher soil water content under Kentucky bluegrass (Poa pratensis L.) after 8 days without addition of water (Johnson et al 2009).…”

Compost can increase soil water availability and nutrient uptake by plants, but it is not clear whether it can also improve the ability of plants to recover after drought stress. Tomato plants (Lycopersicon esculentum L.) were grown in sandy soil without compost or with compost either incorporated or mulched. There were two water treatments: (i) plants grown under sufficient water supply throughout the experiment and (ii) plants grown with sufficient water supply until day 33 after which water was withheld until stomatal conductance was close to zero. Compost addition increased water content at both field capacity and permanent wilting point, but only incorporated compost increased total available water. Compost addition increased shoot and root growth under well-watered and drought stressed conditions with a greater effect by incorporated compost. At sufficient water supply, the rates of photosynthesis and transpiration were similar in all treatments. Drought stressed plants with incorporated compost wilted earlier than control plants, whereas mulched compost increased water availability to plants and hence the number of days until wilting. Photosynthesis and transpiration recovered faster in plants grown with incorporated compost compared to other treatments. The rapid recovery of plants after drought with incorporated compost could be due to their greater root length.
