“…The small difference observed in PAO in the organic soil on Days 1 and 11 after amendment with BR can be explained by the low pH (4.3 at the end of the incubation period) inhibiting nitrifying bacteria. Furthermore, the solubility of heavy metals in the organic residues may increase under acidic conditions, creating a microenvironment toxic to nitrifying bacteria (Gramss et al, 2003). Although some changes in PAO and PDA were detected after the different treatments, they could not explain how N 2 O peaks were regulated.…”

Nitrous Oxide Production from Soils Amended with Biogas Residues and Cattle Slurry

The amount of residues generated from biogas production has increased dramatically due to the worldwide interest in renewable energy. A common way to handle the residues is to use them as fertilizers in crop production. Application of biogas residues to agricultural soils may be accompanied with environmental risks, such as increased NO emission. In 24-d laboratory experiments, NO dynamics and total production were studied in arable soils (sandy, clay, and organic) amended with one of two types of anaerobically digested biogas residues (BR-A and BR-B) generated from urban and agricultural waste and nondigested cattle slurry (CS) applied at rates corresponding to 70 kg NH-N ha. Total NO-N losses from the sandy soil were higher after amendment with BR-B (0.32 g NO-N m) than BR-A or CS (0.02 and 0.18 g NO-N m, respectively). In the clay soil, NO-N losses were very low for CS (0.02 g NO-N m) but higher for BR-A and BR-B (0.25 and 0.15 g NO-N m, respectively). In the organic soil, CS gave higher total NO-N losses (0.31 g NO-N m) than BR-A or BR-B (0.09 and 0.08 g NO-N m, respectively). Emission peaks differed considerably between soils, occurring on Day 1 in the organic soil and on Days 11 to 15 in the sand, whereas in the clay the peak varied markedly (Days 1, 6, and 13) depending on residue type. In all treatments, NH concentration decreased with time, and NO concentration increased. Potential ammonium oxidation and potential denitrification activity increased significantly in the amended sandy soil but not in the organic soil and only in the clay amended with CS. The results showed that fertilization with BR can increase NO emissions and that the size is dependent on the total N and organic C content of the slurry and on soil type. In conclusion, the two types of BR and the CS are not interchangeable regarding their effects on NO production in different soils, and, hence, matching fertilizer type to soil type could reduce NO emissions. For instance, it could be advisable to avoid fertilization of organic soils with CS containing high amounts or organic C and instead use BR. In clay soil, however, the risk of NO emissions could be lowered by choosing a CS.

“…Duplicate 4-g samples of control soil were suspended in 0.2 M phosphate buffers pH 4.4 to 8.1 prepared from KH 2 PO 4 and K 2 HPO 4 , and processed according to GRAMSS et al (2003a). The concentrations of dissolved elements changing with pH were plotted as graphic tools to prognosticate the approximate solubility of an element for a given pH.…”

Fairy rings of M. oreades on pasture land were denoted by the dark-green vegetation. Grasses and rooted soils were analyzed to determine the influence of nonsymbiotic fungal mats on plant uptake of (heavy) metals. In soil colonized by M. oreades, degradation of 20-35% of plant roots in the presence of fungal laccase increased the content of dissolved organic carbon (3.74x), hexose sugar (3.75x), NH(3)/NH(4) (+) (5.1x), NO(3) (-) (11.1x), the number of aerobic bacteria (14.4x), and the formation of the phytochelators, oxalic, citric, and malonic acids. Soil pH diminished by 1.5 units mainly due to nitrification and carboxylic acid production. Although the solubility of trace elements increased (6.1x), plant roots had the same trace metal content as control plants, whereas the shoot content in Al, Cr, Fe, Ni, and Ti decreased by more than 50% due to inhibited root-to-shoot transfer. It is concluded that M. oreades and its associated bacteria increase the solubility of soil minerals significantly, but make them, due to presumed particularities in their complexation, less plant available and less re-complexable for the translocation into the plant vascular system.

“…The strong mobilization of soil organic matter by sucrose application has not been observed before and might be due to desorption and exchange processes from soil colloids. Indications for the existence of these processes are the mobilization of heavy metals after sucrose addition (Gramss et al 2003), but also the priming effect, i.e., an increased mineralization of soil organic matter-derived C (Kuzyakov et al 2000;Blagodatskaya and Kuzyakov 2008), after the application of sucrose (Engelking et al 2007a, b). The microbial biomass C/P ratio was in most samples below the average of 11.4 in 44 German agricultural soils (Joergensen and Emmerling 2006) and varied in a much larger range than the microbial biomass C/N ratio.…”

“…Sucrose addition to soil was useful for analyzing the relationship between C availability and the relative abundance of bacteria (Fierer et al 2007). Sucrose has also been applied to soil for increasing the solubility of heavy metals to facilitate their uptake by hyperaccumulating plants (Gramss et al 2003) and for enhancing plant tolerance to xenobiotics (Sulmon et al 2007). If sugarcane-derived sucrose is used, it is possible to monitor the changes in substrate-derived microbial biomass and residues simply using the differences in the δ 13 C values (Engelking et al 2007a(Engelking et al , 2008.…”

Development of ergosterol, microbial biomass C, N, and P after steaming as a result of sucrose addition, and Sinapis alba cultivation

A pot experiment was carried out to monitor the recovery of a steaming-reduced microbial biomass (C, N, and P) and fungal ergosterol by sucrose addition. The second objective was to investigate the recovery of a steaming-reduced microbial biomass by white mustard (Sinapis alba) cultivation and its interactions with microbial residues, freshly formed from sucrose addition. Thirty days after steaming, the soil microbial biomass C and N was still significantly reduced by 80%, leading to a rather constant microbial biomass C/N ratio around 7 throughout the experiment. The steaming-induced decreases of microbial biomass P and ergosterol were only roughly 50%, leading to a decrease in the microbial biomass C/P ratio and an increase in the ergosterol-to-microbial biomass C ratio. Sucrose addition led to a 25% reduction in the ergosterolto-microbial biomass C ratio. Mustard cultivation had significant positive effects on microbial biomass C, N, P, and ergosterol, but the effects were smaller than those of sucrose addition. Cultivating mustard had no significant effects on the C loss or on the incorporation of sucrose C into the microbial biomass. In contrast, the application of sucrose led to a significant decrease in the mustard shoot biomass and especially in the mustard root biomass.
