Mineralização de compostos nitrogenados de lodos de esgoto na quinta aplicação em Latossolo

Abstract: RESUMOEm sistemas agrícolas em que se aplica lodo de esgoto, devem ser consideradas as necessidades de N das plantas e, simultaneamente, evitar a geração de excesso de nitrato, poluente potencial de águas subsuperficiais. Para isso, na determinação das quantidades máximas a serem aplicadas em determinado cultivo, devem-se conhecer algumas propriedades do lodo de esgoto e do solo. Uma delas é a fração de mineralização de compostos nitrogenados orgânicos (FMN) contidos nos resíduos que serão mineralizados durant… Show more

“…According to Boeira and Maximiliano [18,19], the available N in sewage sludge-amended soils is one of the restrictive factors for residue application in great amounts. This criterion must be considered in regulations for agricultural use of sewage sludge to avoid nitrate enrichment because of its potential to pollute subsurface water bodies.…”

“…Therefore, the objectives of this paper are to present and discuss the long-term effects of continued application of sewage sludge on the microbial biomass C and N, basal respiration, metabolic quotient, enzymatic activity, total carbon and nitrogen, soils δ 13 C, gas fluxes at the soilatmosphere interface, soil suppressiveness to the soilborne plant pathogens, pests and natural enemies, mites and collembolans populations, nitrate leaching, organic nitrogen mineralization rate, heavy metal contents in soil, plants and water, and soil chemical and physical characteristics under field conditions assay conducted in a tropical soil.

“…Organic sources of nutrients may mineralize at lower rates than plant demand for optimum growth in certain soils and a lower asymptote is reached (Barrow and Bolland, 1990). Lower efficiency of sewage materials relative to chemical fertilizers in loam and clayey soils has been reported and attributed to the mineralization rates of organic pools that do not match plant nutritional demands (Boeira and Maximiliano, 2009). In such a situation, chemical sources of nutrients applied on the top of biosolids as supplemental fertilization may be a sound management strategy for crop production (Antille et al, 2013).…”

“…In this sense, cumulative ryegrass yields followed the amounts of organic-N mineralized in soils irrespective of soil and biosolids type (Figure 3). Mineralization is a major event when organic matter sources are incorporated into soils (Boeira and Maximiliano, 2009;Haynes et al, 2009), and the effectiveness of biosolids as N sources to yield plant biomass was mostly determined by the content of organic-N mineralized in soils while plants were growing on them (Figure 3). …”
