Humus horizon development during natural forest succession process in the Polish Carpathians

چکیده
Abstract As a result of socio-economic changes and land abandonment, the main ecological driver Carpathian landscape is progression natural forest succession process. Thus, aspects this process have become worthy attention, especially in context carbon sequestration management protected areas. Soil processes, within topsoil, are some most susceptible to change, due accumulation organic matter during such land-use transformations. The purposes study were investigate differences topsoil development using A Horizon Development Index (ADI) composition humic substances advanced humification different areas selected national parks, i.e. Bieszczady, Magura Pieniny National Parks southern Poland. Additionally, goal was compare ADI spectroscopic coefficients as indicators degree humus horizon shaping well humification. In total, ten transects selected, each consisting three areas: semi-natural meadow, successional old-growth forest. colour determined fresh air-dried samples Munsell chart. soil pH, texture, total nitrogen measured. Humic extracted further characterized by UV-VIS spectroscopy. confirmed influence on darkening uppermost layer. Spectroscopic analyses showed two patterns depending depth. 0–10 cm layer, reduced rate decreased maturity fulvic acids; 10–20 it led an increase decrease content acids at beginning transformation. comparison — ( Q 4/6 , 2/4 2/3 Δ log K ) indicated that these indexes based features cannot be used interchangeably.

Nitrogen alters carbon dynamics during early succession in boreal forest
Boreal forests are an important source of wood products, and fertilizers could be used to improve forest yields, especially in nutrient poor regions of the boreal zone. With climate change, fire frequencies may increase, resulting in a larger fraction of the boreal landscape present in early-successional stages. Since most fertilization studies have focused on mature boreal forests, the respons...

Losses of plant species diversity can affect ecosystem functioning, with decreased primary productivity being the most frequently reported effect in experimental plant assemblages, including tree plantations. Less is known about the role of biodiversity in natural ecosystems, including forests, despite their importance for global biogeochemical cycling and climate. In general, experimental mani...

A non-random sampling design allowed to distinguish within a virgin beech ecosystem two main components of humus profile heterogeneity. The stratification of the profile into horizons reflects changes in the composition of the soil/litter matrix occurring under the influence of the anisotropic deposition of leaf and wood litter and the stratified occurrence of soil organisms (roots, microbes, a...
متن کاملTree–Shrub Interactions During Early Secondary Forest Succession in Uganda
One of the greatest challenges for ecologists this century will be restoring forests on degraded tropical lands. This restoration will require understanding complex processes that shape successional pathways, including interactions between trees and other plants. Shrub species often quickly invade disturbed tropical lands, yet little is known about whether they facilitate or inhibit subsequent ...
