Winter Wheat Straw Decomposition under Different Nitrogen Fertilizers

Popis výsledku v původním jazyce

The climate change and increased drought frequency still more frequent in recent periods bring challenges to management with wheat straw remaining in the field after harvest and to its decomposition. The field experiment carried out in 2017-2019 in the Czech Republic aimed to evaluate winter wheat straw decomposition under different organic and mineral nitrogen fertilizing (urea, pig slurry and digestate with and without inhibitors of nitrification (IN)). Treatments Straw 1 with fertilizers were incorporated in soil each year the first day of experiment. The treatments Straw 2 were placed on soil surface at the same day as Straw 1 and incorporated together with fertilizers after 3 weeks. The Straw 1 decomposition in N treatments varied between 25.8-40.1% and in controls between 21.5-33.1% in 2017-2019. The Straw 2 decomposition varied between 26.3-51.3% in N treatments and in controls between 22.4-40.6%. Higher straw decomposition in 2019 was related to more rainy weather. The drought observed mainly in 2018 led to the decrease of straw decomposition and to the highest contents of residual mineral nitrogen in soils. The limited efficiency of N fertilisers on straw decomposition under drought showed a necessity of revision of current strategy of N treatments and reduction of N doses adequately according the actual weather conditions.
