The Effects of Windthrow Damage on Soil Properties in Scots Pine, Black Pine and Kazdağı Fir Stands in the Northwest Turkey

Abstract

Aim of study:The short-term effects of windthrow damage on soil properties were investigated in Kazdağı fir (Abies nordmanniana subsp. equi-trojani), Scots pine (Pinus sylvestris L.) and black pine (Pinus nigra Arnold.) stand in northwest Turkey.Area of study: The study was carried out in Kastamonu and Sinop regions.Material and methods: In order to understand the effects of windthrow damage occurred in 2013, soil samples were collected at a depth of 0-30 cm from the disturbed and undisturbed sites in 2018 (5 year later), and analyzed for soil physical and chemical properties.Main results: The increases in temperature, wind speed and heavy rainfall in the study sites seemed to result in the windthrows. There were significant differences in soil physical and chemical properties among the three tree species, and also between the disturbed and the undisturbed sites.Highlights: After the windthrows, increased SOC and TN stocks, P and K could be related to the accumulation of organic matter. However, we were not able to identify a single mechanism to explain this observed relationship. Thus, the root-soil interactions of the three tree species should be conclusively examined in future studies in order to define the relationships between soil chemical properties and root features.

The Effects of Stand Development Stages on Soil Carbon and Nitrogen Stocks in Black Pine, Scots Pine and Fir Stands in Türkiye

“…Black pine, Scots pine, and Kazdağı fir are economically and ecologically important tree species in Turkey (Savacı et al, 2021). All trees are distributed over 4.199.623 hectares, 1.410.177 hectares, and 511.703 hectares, which account for 18.31%, 6.15%, and 2.23% of the overall forest coverage, respectively (OGM, 2020).…”

Emissão de gases de efeito estufa do solo em áreas de Blowdown na Amazônia Central

“…Santos et al (2016) relataram que ocorreu um grande aporte de serapilheira, associadas a queda da floresta, mas consideraram o aumento encontrado no COT como de curto prazo, relacionado com a rápida ciclagem de nutrientes e reestabelecimento da floresta em áreas tropicais, concluindo que quanto maior o conteúdo de COT maior é a resiliência da floresta. Corroborando com Sterzyńska e Skłodowski (2018), em área temperada, também associaram maiores taxas de COT ao aumento do fechamento do dossel dos povoamentos de pinheiros.Após os distúrbios causados por ventos, observou-se o aumento dos estoques de COT e TN(Savaci et al, 2021). A abertura do dossel está associada ao aumento do pH e da umidade do solo(Sterzyńska;Skłodowski, 2018) Bowden et al (1993).…”
