“…Additionally, the soil of Texcoco is N-depleted, so it can be speculated that some of the NH 4 + was immobilized into the microbial biomass considering the large amounts of CO 2 emitted. Deni and Penninckx [16] found that the addition of hydrocarbons at a rate of 4 g C kg -1 soil stimulated immobilization of N. It is known that the addition of organic material, especially that with large C-to-N ratio, such as acetone and wastewater sludge, will induce N immobilization [17]. Acetone can be used as C substrate by soil microorganisms, e.g., Methylobacterium, Rhodococcus, and Arthrobacter [11], but it is N-free so upon decomposition microbial N immobilization can be induced.…”

“…Therefore, studies were conducted to determine the rate of decomposition and N cycling of Fluff at increasing rates in two distinct sandy soils and comparing them to mature commercial municipal waste compost . In the Busby et al (2007) study, a 90 d incubation was performed to measure C and N mineralization of composted and un-composted municipal wastes at varying rates. Total C and N of both organic additives were analyzed and indicated that Fluff had a much higher C content but similar nitrogen concentration compared to the compost (Table 3).…”

“…For these reasons it is convenient to know the effects of applying different doses of pig slurry on the global microbiological activity and transformations of soil N. This type of study could contribute to reduce the excess of N with the subsequent leaching of nitrates and groundwater contamination in the soils resulting from aggregate extraction. For this purpose, incubations in the laboratory of soil mixed with pig slurry, under controlled conditions of moisture and temperature, have been shown to be useful tools delivering valuable information on the potential C and N mineralization (Busby et al, 2007).…”

Pig slurry as a fertilizer source has been extensively used in agriculture; however, in order to reduce the risks of contaminating the water supplies given its high level of N sources, it is important to understand the N transformations occurring in the soil where it is applied. In this study, incubations were performed at 25 °C for a period of 63 to 73 d to evaluate the effect of different doses of pig slurry on the global microbiological activity and the N dynamics in time, with an emphasis on N mineralization and nitrification in a soil subject to aggregate extraction. The slurry was applied in doses equivalent to: 0, 162, 244, and 325 m 3 ha -1, constituting four treatments: T0, T50, T75, and T100, respectively. The microbiological activity and the contents of NH 4 + -N and NO 3 --N were measured. Increasing doses of slurry produced an increase in the evolution of the accumulated CO 2 , with 63.5, 115.0, 112.7, and 125.7 mg 100 g -1 soil for T0, T50, T75, and T100 respectively. A similar situation was observed in the initial contents of NH 4 + -N, which were 22.4, 30.3, 44.3, and 60.7 mg kg -1 in each treatment, respectively. On the other hand, the increase in NO 3 --N contents were only noticed by the end of the incubation period and corresponded to 28.6, 69.0, 95.3, and 109.8 mg kg -1 . In addition, the net N mineralization was predominant in all treatments with slurry during the measurement period, being 9.1, 45.4, 58.1, and 52.7 mg kg -1 for T0, T50, T75 and T100, respectively, at the end of the trial. The mineralization rate of the organic C decreased when increasing the dose of slurry and the mineralization rate of the organic N resulted to be low, which would indicate a high contribution of material resistant to degradation by the slurry, which could have a long term effect in the soil.
