Changes on soil structural stability after in natura and composted chicken manure application

Abstract

Purpose Many studies evaluate the effect of successive applications of chicken manure on soil attributes. In Brazil, the commercialization of this waste is common, implying on its sporadic use instead of many applications at the same area. The short-term effects of a single application of chicken manure and the role of its composting on soil structural stability are not fully understood. This study investigated application of in natura (uncomposted) and composted chicken manure on the structural stability of a Rhodic Ferralsol after a short period following single application. Methods The experiment was performed in a Rhodic Ferralsol in Londrina, Paraná. Brazil. We applied in natura and composted chicken manure at doses of 4.5, 9.0, 13.5, and 18.0 Mg ha −1 plus a control without application. Soil samples were collected after 185 days at the 0.0-20.0 cm layer for laboratorial analysis. Results The composting of chicken manure did not affect soil structural stability. Chicken manure did not alter water-dispersible clay (x = 21.7%), but increased the mean weight diameter of water-stable aggregates (MWD = 5.43 + 0.068 × dose) through the agglomeration of aggregates with 0.5-4 mm into 8-19 mm. Conclusion Even after a short period of 185 days, the application of chicken manure increases the structural stability of Rhodic Ferralsols and its composting, in the way performed by many farmers, is not associated with the improvement of soil structural stability in short-term. However, other advantages arise from the composting of the manure and need to be considered prior its use.

The potential of recycling wool residues as an amendment for enhancing the physical and hydraulic properties of a sandy loam soil

“…Carbon in soil aggregates increases their stability since it decomposes slowly or not at all (Beare et al 1994). Other authors reported the positive effect of OM on the formation of large aggregates (Šimanský et al 2008;de Melo et al 2019) and in maintaining their stability in most agricultural soils (Le Guillou et al 2011;de Melo et al 2019). Furthermore, the release of soluble salts in SWRs could help to improve soil aggregates formation and stability by promoting flocculation of clay minerals (Lakhdar et al 2010).…”

“…Frequent drought events due to climate change and global food demand in the coming decades urge effective actions for a more efficient use of natural resources (FAO 2015; Lee et al 2017;Wasaya et al 2018). Soil organic matter (OM) plays an important role in the regulation of soil water-dynamics by enhancing soil physical characteristics (structure, porosity, water retention, permeability) (de Melo et al 2019), and in promoting microorganisms (Williams et al 2016;Minasny and McBratney 2018;Ghosh and Devi 2019). An increase in soil organic carbon (OC) often leads to an increase in crop yield (Alagöz and Yilmaz 2009;Oguntade et al 2018;Ben Mbarek et al 2019) and can mitigate the effects of climate change by storing CO 2 in the soil (Williams et al 2016;Minasny and McBratney 2018).…”

Aggregation rate as a function of soil organic matter in heavy clayey Ferralsols

“…Rev Bras Cienc Solo 2022;46:e0220035 These soils commonly present values of TOC higher than 20 g kg -1 in the surface layer because of their high clay content (Melo et al, 2019). Consequently, most of the dynamics caused by organic matter change in the surface layer are expected to happen in macroaggregates because free microaggregates (not aggregated into macroaggregates) are scarce (Figure 1 and Figure 3b).…”

Cama de aves de corral un factor importante en la seguridad alimentaria

“…Por esta razón, un buen tratamiento de las camas es vital para reciclar grandes cantidades de desechos orgánicos que son una fuente importante de fertilizantes para uso agrícola (De Melo et al, 2019). En este sentido, con el fin de disminuir olores desagradables, niveles de amoniaco y carga de patógenos en las camas, son utilizados procedimientos químicos, físicos y biológicos (Kim et al, 2012;Pereira, 2016;Thomas et al, 2019).…”
