“…Similarly, the amount of phosphorus extractable in water appears to have been influenced by manure additions. Royer et al (2003) have reported similar results after 8 years of liquid hog manure application to a silt loam soil. The high amount found in the subsoil of the control relative to the topsoil may be attributed to its finer texture that might have delayed leaching towards the deeper layers.…”

The widespread recycling of animal wastes as fertilizers can severely affect the phosphorus cycle, especially in soils that undergo periodical flooding and anaerobiosis. The aim of this study was to investigate the effect that reducing conditions have on the release and forms of P in soils that have received different doses (0, 60 and 120 Mg/ha) of liquid hog manure for 15 years. Samples of the topsoil (0-20 cm) and of subsoil (20-40 cm) were placed under static reducing condition. At the onset of the reduction, P release to the solution reached a maximum after 4 weeks of submersion then levelled off, presumably due to readsorption by the soil matrix. When an anionic resin was added to act as a P-sink the amount of P released nearly doubled for most samples. The soils that had received the highest dose of manure released more P than the others. Draining the soil solution at intervals after reduction removed up to 683 lg P/kg of the soil with the highest manure dose. The forms of P measured after the experiments revealed a shift of the resilient forms towards more labile, bioavailable forms thus increasing the potential for P loss.

“…Unlike synthetic N fertilizers, legumes utilized as GM represent a potentially renewable source of on‐farm, biologically fixed N and may also fix and add large amounts of C to cropping systems (Hargrove, 1986; Sharma and Mittra, 1988). Providing adequate soil N fertility with application of animal manure products may result in soil P loading (because manure N/P ratios are often much lower than those maintained by plants; Royer et al, 2003; Hao et al, 2004) or soil salinization (due to high ion concentrations in animal manure; Hao and Chang, 2003). Such excess P application and soil salinization may be avoided by use of leguminous GMs (Eigenberg et al, 2002).…”

Green Manure Approaches to Crop Production: A Synthesis

2006

A green manure (GM) is a crop used primarily as a soil amendment and a nutrient source for subsequent crops. Green manure approaches to crop production may improve economic viability, while reducing the environmental impacts of agriculture. However, such approaches are complex because they depend on interactions between the GM, the environment, and management. We suggest that the research and management techniques developed for synthetic inputs are not adequate for effective GM use. This review provides a conceptual framework to more critically evaluate GM use, and we discuss a limited number of key examples involving GM adaptation and growth, effects on soil organic matter, N release and availability for future crops, and pest control. We explore the deficiencies in our current understanding of GM approaches and argue that economic justification of GM requires provision of multiple services (such as nutrient supply, pest and weed control, and increase of soil organic matter). We propose that future research efforts make improved use of whole systems and participatory strategies to better address both the complexity of GMbased cropping systems and the obstacles preventing farmer adoption of GM approaches.

“…The enhanced level of POM-C, however, could also be related to infiltration of LSM into the soil profile when applied at the high rate (Bakhsh et al 2001;Elmi et al 2005). In this regard, even nutrients of low mobility such as P could pose a risk of movement to drainage waters with repeated LSM application at high rates (Royer et al 2003).…”

. 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...
