Disentangling the rhizosphere effect on nitrate reducers and denitrifiers: insight into the role of root exudatesNARA Subscribed
Summary To determine to which extent root‐derived carbon contributes to the effects of plants on nitrate reducers and denitrifiers, four solutions containing different proportions of sugar, organic acids and amino acids mimicking maize root exudates were added daily to soil microcosms at a concentration of 150 μg C g −1 of soil. Water‐amended soils were used as controls. After 1 month, the size and structure of the nitrate red...
This paper presents a new algorithm, Nitrous Oxide Emission (NOE) for simulating the emission of the greenhouse gas N 2 O from agricultural soils. N 2 O fluxes are calculated as the result of production through denitrification and nitrification and reduction through the last step of denitrification. Actual denitrification and nitrification rates are calculated from biological parameters and soil water‐filled pore space, temper...
