“…Most of the potato yield parameters were influenced only by rotation. A similar conclusion was obtained in the soil-borne disease studies (Peters et al 2003(Peters et al , 2004 conducted in this experiment. The 3-yr rotation reduced the severity of soil-borne disease, compared with the 2-yr rotation, and this could explain some of the potato marketable tuber yield differences.…”

“…Crop rotations via nutrient cycling, carbon addition and soil structure modification, use of leguminous crops such as clover, and disease suppression can indirectly modify crop growth conditions and crop production (Neeteson 1989;Peters et al 2003Peters et al , 2004Ball et al 2005;Mallory and Porter 2007). In Prince Edward Island potato cropping systems, the type of companion-crop (generally red clover and barley) and frequency of the potato crop in the rotation can influence potato productivity, soil properties (Angers et al 1999;, soil-borne disease development (Peters et al 2003(Peters et al , 2004, and soil nitrogen .…”

. Long-term conservation tillage in potato rotations in Atlantic Canada: Potato productivity, tuber quality and nutrient content. Can. J. Plant Sci. 89: 273Á280. Conservation tillage in combination with mulches in potato (Solanum tuberosum L.) farming systems can maintain crop productivity and improve soil properties, in comparison with conventional tillage systems. However, information is needed on the long-term influence of such practices on potato crop parameters. A study was initiated in 1994 on a Charlottetown fine sandy loam (Orthic Podzol) in Prince Edward Island to assess the feasibility of using conservation tillage practices in combination with crop residue mulches (after the potato harvest) on potato production in two different potato rotations: a 2-yr barleyÁ potato rotation and a clover-based 3-yr (barleyÁred clover Ápotato) rotation. In the conservation tillage system, the primary tillage event was moved from the autumn to spring and the degree and depth of tillage were reduced by replacing the conventional mouldboard plough (20 cm depth) with a shallow (15 cm depth) one-pass chisel plough just prior to potato planting. Potato yield and tuber quality, surface residue levels after potato planting, and tuber mineral content were evaluated from 2000 to 2007. Adoption of conservation tillage over the long-term did not adversely influence total or marketable potato yield, or tuber quality. The clover-based 3-yr rotation, compared with the 2-yr rotation, had little effect on total potato yield (42 vs. 44 Mg ha(1 ), but produced significantly higher marketable tuber yields (38 vs. 32 Mg ha(1 ), for four of the eight yrs of the study. The conservation tillage system, for both rotations, provided relatively high surface residue levels (30%) after potato planting, compared with the bare soil surface in the conventional tillage system. Nutrient and trace element contents in tuber dry matter were similar between conservation and conventional tillage. Tuber uptake of nitrogen and other nutrients were slightly greater under the 3-yr, compared with the 2-yr rotation, and associated with tuber dry-matter yield differences. The results of the 14-yr study confirm the conclusions of previous short-term studies that a reduction in depth and intensity of tillage for potato culture is yield neutral, and a viable alternative to conventional tillage systems for potato production on sandy loams in eastern Canada.

“…Changes in the abundance and diversity of soil microbial communities affect agriculturally important soil microbiological processes like cycling of nutrients, maintenance of soil structure, degradation of agrochemicals and pollutants, and the control of plant and animal pests. For example, crops grown on soils with high organic matter and active soil organisms tend to be less infested with weeds (Kremer and Li 2003), diseases (Bailey and Lazarovits 2003;Peters et al 2003) and insect pests (Altieri and Nicholls 2003). Reduced tillage and inclusion of legumes in crop rotations are examples of crop management practices that have been shown to increase soil microbial biomass and diversity in Canadian soils (Carter and Rennie 1982;Franzluebbers and Arshad 1997;Lupwayi et al 1998) and elsewhere (Hassink et al 1991;Wander et al 1995;Aon et al 2001;Pankhurst et al 2002).…”

Soil microbiological properties during decomposition of crop residues under conventional and zero tillage. Can. J. Soil Sci. 84: 411-419. Field experiments were conducted to correlate decomposition of red clover (Trifolium pratense) green manure (GM), field pea (Pisum sativum), canola (Brassica rapa) and wheat (Triticum aestivum) residues, and soil organic C (SOC), under zero tillage and conventional tillage, with soil microbial biomass C (MBC), bacterial functional diversity and microbial activity (CO 2 evolution). A greenhouse experiment was also conducted to relate crop residue quality to soil microbial characteristics. Zero tillage increased MBC only in the 0-to 5-cm soil layer. Soil MBC decreased more with soil depth than either microbial diversity or total SOC. Legume GM residues induced greater initial CO 2 evolution than the other residues. This means that results that do not include the initial flush of microbial activity, e.g., by sampling only in the season(s) following residue placement, probably underestimate gas evolution from legume crop residues. Residue N, P and K contents were positively correlated with microbial functional diversity and activity, which were positively correlated with crop residue decomposition. Therefore, microbial functional diversity and activity were good indicators of microbial decomposition processes. Residue C/N and C/P ratios (i.e., high C content) were positively correlated with MBC, which was positively correlated with SOC. Therefore, soil MBC was a good indicator of soil quality (soil organic matter content). Les auteurs ont effectué des essais sur le terrain en vue de corréler la décomposition de l'engrais vert (EV) de trèfle des prés (Trifolium pratense) et des résidus de pois de grande culture (Pisum sativum), de canola (Brassica rapa) et de blé (Triticum aestivum) ainsi que la concentration de C organique dans le sol (COS) avec la biomasse microbienne du sol (BMS), la diversité fonctionnelle de la microflore et l'activité microbienne (évolution du CO 2 ) quand le sol est travaillé de la manière usuelle ou n'est pas travaillé. Ils ont aussi réalisé une expérience en serre pour établir le lien entre la qualité des déchets de culture et les propriétés de la microflore tellurique. Le non-travail du sol n'augmente la BMS que dans la couche supérieure de 0 à 5 cm du sol. La BMS diminue plus avec la profondeur qu'avec la diversité de la microflore ou la concentration totale de COS. Les résidus d'EV de légumineuses entraînent une évolution initiale plus rapide du CO 2 que les résidus d'une autre nature. On en déduit que les résultats ne tenant pas compte de l'explosion d'activité initiale de la microflore (à savoir obtenus uniquement après échantillonnage du sol la ou les saisons suivant l'incorporation des résidus) pourraient sous-estimer l'évolution gazeuse des résidus de légumineuses. La concentration de N, de P et de K dans les résidus présente une corrélation positive avec la diversité fonctionnelle et le degré d'activité de la microflore, qui sont elles-mêmes corré...

“…Many plant diseases are difficult to control using conventional methods, such as the adoption of resistant cultivars or the application of agrochemicals (Weller et al, 2002). The interaction between plant pathogens and other components of the soil microbial community is a factor in plant health, which is an important component of soil quality (Peters et al, 2003). Suppression of plant disease by soils is a well-documented phenomenon established in the 1970s by Baker and Cook (1974), who defined soil suppression as "the capacity of a soil to maintain a low incidence or severity of a specific plant disease even in the presence of the pathogen, susceptible plants and favorable environmental conditions for the development of the disease.…”

Soil management, in terms of tillage and cropping systems, strongly influences the biological properties of soil involved in the suppression of plant diseases. Fungistasis mediated by soil microbiota is an important component of disease-suppressive soils. We evaluated the influence of different management systems on fungistasis against Fusarium graminearum, the relationship of fungistasis to the bacterial profile of the soil, and the possible mechanisms involved in this process. Samples were taken from a long-term experiment set up in a Paleudult soil under conventional tillage or no-tillage management and three cropping systems: black oat (Avena strigose L.) + vetch (Vicia sativa L.)/maize (Zea mays L.) + cowpea (Vigna sinensis L.), black oat/maize, and vetch/maize. Soil fungistasis was evaluated in terms of reduction of radial growth of F. graminearum, and bacterial diversity was assessed using ribosomal intergenic spacer analysis (RISA). A total of 120 bacterial isolates were obtained and evaluated for antibiosis, and production of volatile compounds and siderophores. No-tillage soil samples showed the highest level of F. graminearum fungistasis by sharply reducing the development of this pathogen. Of the cropping systems tested, the vetch + black oat/maize + cowpea system showed the highest fungistasis and the oat/maize system showed the lowest. The management system also affected the genetic profile of the bacteria isolated, with the systems from fungistatic soils showing greater similarity. Although there was no clear relationship between soil management and the characteristics of the bacterial isolates, we may conclude that antibiosis and the production of siderophores were the main mechanisms accounting for fungistasis.
