The effect of wheat straw quality on the rate of its mineralisation in soil


The aim of this study was to assess the effect of straw of two spring wheat cultivars, Tybalt – with the culm filled with pith, and Ostka Smolicka – with the hollow culm, added to light textured soil, on the mineralisation rate of organic matter. The incubation experiment was established under laboratory conditions and comprised three experimental combinations: K1 was soil with an addition of pith-filled culms, K2 – soil with an addition of straw with hollow culms, and K0 – the control with no straw added. In all the combinations, mineral fertilisation was applied in the form of urea. Incubation lasted for 14 months. At specific dates the amounts of CO2 released within 24 h and pH values were recorded. The rate of organic matter mineralisation was expressed in mg CO2·d−1. Analyses showed that the addition of straw, both with pith-filled and hollow culms, significantly influenced the mineralisation of organic matter in the first months of incubation. Mineralisation was most intensive in the soil incubated with straw with hollow culms. The large amount of released carbon dioxide in the first days of incubation caused a decrease in pH both in the control soil and in soils with the addition of straw. The change in the soil reaction to its initial value was recorded at day 222 for the soil combination K0 and at day 250 of incubation in soils fertilised with straw.

Indicators of peat soil degradation in the Biebrza valley, Poland

wetlands [Joosten, Clarke 2002; Kalbitz, Geyer 2002; Bellamy et al. 2005 ; Smith et al. 2007 ; Kruger et al. 2015; Lane et al. 2016 ]. The loss of water from peat and temperature rise are thought to be the most important drivers of SOM mineralisation in peat soil decay, entailing increased CO 2 and N 2 O emission as well as mineral element leaching to groundwater. The processes of greenhouse gases exchange at the interface between wetland ecosystems and the atmosphere are, however, much more complicated and also involve CO 2 uptake by plants. The CO 2 uptake in
