Utilizing woody materials for fungal-based management of soil nitrogen pools

Application of nitrogen fertilizers to reach high crop production is common practice. However, this has a environmental cost, irrespectively the synthetic or organic origin fertilizer. In particular, intensively managed arable soils often fail retain excess nitrogen, which leads contamination ground- and surface water. Next abiotic factors like soil texture, limited retention ascribed low activity saprotrophic fungi. It been shown that amendment with cellulose-rich materials can effectively stimulate resident The current study investigated relationship between fungal dynamics (biomass, composition) immobilization-remobilization upon woody materials. Mineral pools, ergosterol ITS2 amplicon sequences were analyzed during 6-month pot experiment. Carbon-rich amendments included sawdusts deciduous (beech, willow) coniferous (Douglas fir, larch) tree species, beech wood chips, wheat straw combinations these Excess derived from addition either mineral Deciduous sawdust resulted in rapid stimulation biomass, mainly consisting Sordariomycetes. This was accompanied by reduction N pool up 17 kg t?1 wood, followed gradual remobilization. intensity immobilization depended on type Nitrogen single lowest, but prolonged when combined sawdust. Our conclusion fungus-stimulating have great potential reduce losses soils.
