“…Our results suggest that managers can opt for less expensive options, such as simple disk trenching, or those treatments that are least damaging to the environment, such as inversion, depending upon local management constraints, with negligible effects on initial planting performance. However, it should be noted that this was a 2-year study and that short-term impacts of site preparation treatments are not always indicative of future trends (Munson et al 1993). Site preparation effects are dynamic and may involve the progressive emergence of competing vegetation or changes in soil nutrient availability through time (Munson et al 1993;Thiffault et al 2004).…”

Early performance of planted hybrid larch: effects of mechanical site preparation and planting depth

Some site preparation is generally recommended to enhance the growth and survival of planted and naturally regenerated seedlings, but must be justified both economically and environmentally. More severe preparation is thought to be necessary for intensive plantation silviculture, e.g., using fast-growing, ameliorated stocks, especially in boreal ecosystems. Although not justified scientifically, deep-planting of seedlings is often 2 discouraged and may even be financially penalized in eastern Canada. We thus evaluated early seedling growth and survival of hybrid larch (Larix x marschlinsii Coaz) in an experiment including mechanical site preparation and planting depth treatments. Our results suggest that satisfactory early hybrid larch establishment and growth could be met using low environmental impact or low cost treatments (such as soil inversion using an excavator or single-pass disk trenching), and that depth of planting has no negative effect.Structural equation modelling (SEM) was used to explore causal relationships between factors influencing seedling performance at the local scale (planting microsites), including soil moisture, soil temperature, surrounding vegetation, and seedling nutrition.SEM analysis supported the absence of overall differences among treatments, while also highlighting the negative impact of increased soil water content where drainage was suboptimal, as well as the unexpected positive impact of increased competition on growth mostly through seedling nutrition, among others. These early observations will need to be confirmed over a longer period, as well as with a more comprehensive assessment of site environmental conditions and competition intensity.

“…Nitrification is a strong acidifying process that can displace nutrient bases from the exchange complex and mobilize A1 into solution (Sposito 1989 Munson et al (1993)]. These decreases are generally associated with the displacement of forest floor and surface mineral soi1, Smethurst and Nambiar (1990b) Smethurst and Nambiar (1990b Overall, the blade-thin areas showed the greatest differences in soil chemical properties.…”

“…Harvesting may result in elevated available p due to rncreased organic matter decomposition and p release at raised temperature (Krause and Ramlal l9g7). MSp has been shown to cause reductions in available p (Tuttle et al 1985;Krause and Ramlal 1987;Munson et al 1993) as well as reduced N and C in surface soils (Tuttle et al l9g5;Munson et al 1993) due to the displacement of forest floors.…”

Effects of sylvicultural practices on nutrient status in a Pinus radiata plantation: Nutrient export by tree removal and nutrient dynamics in decomposing logging residues

2001

-The effects of logging residue management practices on export and dynamics of nutrients were studied in a plantation of Pinus radiata D. Don growing on an infertile soil, in a humid, temperate area of NW Spain. The export of nutrients due to the removal of wood and logging residues during thinning and clear-cutting was evaluated by estimation of nutrient stores in the above-ground biomass and in the soil. Nutrient dynamics in decomposing slash needles and twigs were monitored over one year in a thinned stand and in an adjacent clear-cut area. Comparison of nutrient release in decaying residues with the nutrient store in tree biomass as well as inputs via litterfall and atmosphere allowed discussion of possible implications for sustainable sylviculture in these plantations. Nutrient release from decomposing material increased following clear-cutting and to an even greater extent, after mechanical incorporation of logging residues to the mineral soil, which substantially increased the short-term flush of some nutrients. logging residues / decomposition / tree harvesting / thinning / forest nutrient cycling Résumé -Effets des pratiques forestières sur la nutrition d'un peuplement de Pinus radiata : exportation des éléments minéraux et dynamique des résidus en décomposition. Les effets de l'utilisation des résidus d'exploitations forestières sur l'exportation et la dynamique des éléments minéraux ont été étudiés dans une plantation de Pinus radiata D. Don située sur une station non fertile et dans une région humide et tempérée du Nord-Ouest de l'Espagne. Le flux d'éléments minéraux dû à l'exportation du bois et des résidus de l'exploitation forestière à la suite d'une éclaircie et d'une coupe rase a été évalué à partir de l'estimation des réserves d'éléments minéraux dans la biomasse aérienne forestière et dans le sol. La dynamique des éléments minéraux provenant des résidus en décomposition d'aiguilles et de brindilles a été suivi pendant un an dans une parcelle éclaircie et aussi dans une zone de déboisement adjacente. La comparaison de la libération d'éléments minéraux en décomposition avec la réserve d'éléments minéraux dans la biomasse des arbres, de même que les apports par les pluviolessivats et les pluies incidentes nous ont permis de discuter des implications possibles pour assurer la pérennité de la production forestière. La libération des éléments minéraux à partir de matières en décomposition augmente après le défrichement total, et ceci tout particulièrement après l'incorporation mécanique des résidus d'exploitations forestières au sol minéral, laquelle augmente de façon appréciable la libération d'éléments minéraux. résidus d'exploitation forestière / décomposition / récolte / éclaircissement / dynamique des éléments minéraux Ann.
