Influence of tillage and liquid swine manure on productivity of a soybean-barley rotation and some properties of a fine sandy loam in Prince Edward Island

Abstract

. 2006. Influence of tillage and liquid swine manure on productivity of a soybean-barley rotation and some properties of a fine sandy loam in Prince Edward Island. Can. J. Soil Sci. 86: [741][742][743][744][745][746][747][748]. Interactions between tillage management for manure incorporation and rate of manure application may influence crop productivity and soil properties. This study was conducted to evaluate the effect of liquid swine (Sus scrofa L.) manure (LSM) applied at three N rates (40, 80, 160 kg ha -1 ), compared with mineral N fertilizer, in a 2-yr barley (Hordeum vulgare L.)-soybean (Glycine max L. Merr.) rotation, incorporated by two tillage methods (chisel plough and disc), on crop yield and quality and some soil properties, especially C parameters. The LSM was applied every second year in the spring, prior to barley seeding. The study was conducted over a 5-yr period on a Charlottetown fine sandy loam (Orthic Humo-Ferric Podzol) in Prince Edward Island. The experimental design was a split-plot with four replicates. Soil samples (0-60 cm) were obtained at the termination of the study to determine residual effects of the LSM on soil properties. The two methods of LSM incorporation had no differential effect on crop response. Generally, increasing the application rate of LSM increased the barley yield, but had no effect on grain N concentration. A residual effect on crop grain yield for the high rate of LSM was evident in the soybean year. Crop response to LSM was similar to that of mineral fertilizer. Application operations for LSM had no adverse effect on soil strength or soil bulk density. Soil properties (microbial biomass C, carbohydrates, water-stable aggregates) were not greatly influenced by LSM application, however, increases in particulate C (POM-C) were evident for the high LSM rate at the 10-to 30-cm soil depth. The study showed that for fine sandy loams in Prince Edward Island low to medium rates of LSM applied every second year could serve as a source of N for barley in barley-soybean rotations. . Les amendements ont été incorporés au sol de deux manières : par charrue à ciseau et par charrue à disques). Le PP a été appliqué un an sur deux au printemps, avant l'ensemencement de l'orge. L'étude a duré cinq ans et s'est déroulée sur un fin loam sablonneux (podzol orthique humo-ferrique) de Charlottetown, à l'Île-du-Prince-Édouard. L'expérience portait sur des parcelles divisées et comptait quatre répétitions. À la fin de l'expérience, les auteurs ont prélevé des échantillons de sol (0 à 60 cm de profondeur) afin d'établir les effets résiduels du PP sur les propriétés du sol. La culture ne réagit pas de manière différente aux deux méthodes d'incorporation du PP. En général, le taux d'application du PP accroît le rendement de l'orge sans modifier la concentration de N dans le grain. L'année de l'assolement soja, le taux d'application du PP le plus élevé a eu un effet résiduel sur le rendement grainier. La culture réagit de la même façon au PP et à l'amendement minéral. Le travail du sol néc...

Chemical and Microbiological Attributes of Soil Under Different Management With Application of Swine Wastewater

“…8; organic substrates provided by the SWW, which would not be enough for a long-term maintenance of the microbial development, as suggested Plaza et al (2007). The application of 40 to 160 kg ha -1 of SWW on a clayey-sandy soil (Orthic Humo-Ferric Podzol) for 5 years did not change the MBC (Carter & Campbell, 2006), corroborating the results presented here. SWW has low C/N ratio (Aita et al, 2007) that makes easy its mineralization in the soil.…”

“…Consequently, a long-term effect of SWW applications on MBC would not be expected because the C sources in the residue are fast mineralized and do not lead to the formation of SOM. Although MBC is a biological indicator sensitive to soil changes, its response depends on the amounts and quality of C compounds applied via residue and the C dynamics over time (Carter & Campbell, 2006).…”

Yield and quality of oat in response to varying rates of swine slurry

“…There have been a number of studies to determine the effect of rate of swine manure slurry application on grain and dry matter yield of multiple varieties of soybean (Schmidt et al 2001) and single varieties of barley (Brechin and McDonald 1994;Petersen 1996;Mooleki et al 2002;Carter and Campbell 2006). Generally, increasing rates of swine slurry increased yields of soybean and barley; however, for both crops, Abbreviations: CP, crude protein; DM, biomass dry matter; FGS, Feekes growth stage; SL, swine manure slurry; TAN, total ammonical nitrogen; TKW, 1000-kernel weight low nutrient use efficiency of slurry N did not justify the use of rates of slurry higher than the recommended fertilizer-N rate.…”

Biowaste usage for soil erosion control and soil physical improvement under potatoes (Solanum tuberosum) in Atlantic Canada

“…These bulk samples were collected within both the 0Á15 cm and 15Á30 cm soil depths immediately after BD sampling and close to the respective BD sampling points. Using a portion of the bulk sample collected for AgSt, SWC was determined gravimetrically as employed by Carter and Campbell (2006). Soil organic matter (SOM) was determined on air-dried soil bulk-sampled from within the 0Á15 cm soil depth using the method employed by Aoyama et al (1999).…”
