Abstract
Contents of labile carbon and nitrogen under different soil management practices in a vineyard in an extremely humid year
Highlights
The soil organic matter is a key driving factor for the long term sustainability of agro-ecosystems
Its effectiveness is closely related to the adoption of suitable soil management practices, providing a steady state equilibrium with respect to amount, composition and dynamics of different organic matter pools (Canellas et al, 2014)
During the period of 12 months of the year 2010 of this study, CL under G + NPK3 (2405 mg kg-1) was higher than in Co (2124 mg kg-1) which is in contrast to the results of Semenov et al (2008)
Summary
The soil organic matter is a key driving factor for the long term sustainability of agro-ecosystems. The dynamics of organic and labile carbon in soil (Blair et al, 1995; Szombathová, 1999) as well as in waterstable aggregates (Šimanský, 2013) due to its relatively wide range can be considered as an important and sensitive indicator of the quality of the soil environment under different soil management practices. Changes in the content of labile and soluble forms of C are well documented under different soil and climatic conditions (Blair et al, 1995; Szombathová, 1999; Tobiašová, 2012; Šimanský and Jonczak, 2016). Information on potentially mineralizable nitrogen, in relation to different soil management practices, is minimal. This information can play a crucial role in maintaining efficient N utilization and sustainable agriculture (Mason et al, 2000)
