Role of plant residues in determining temporal patterns of ...

The incorporation of plant residues into soil not only represents an opportunity to limit soil organic matter depletion resulting from cultivation but also provides a valuable source of nutrients such as nitrogen. However, the consequences of plant residue addition on soil microbial communities involved in biochemical cycles other than the carbon cycle are poorly understood.

10%  Feb 11, 2021  Aims. Plant residues decomposing within the soil matrix are known to serve as hotspots of N 2 O production. However, the lack of technical tools for microscale in-situ N 2 O measurements limits understanding of hotspot functioning. Our aim was to assess performance of microsensor technology for evaluating the temporal patterns of N 2 O production in immediate vicinity to decomposing plant ...

Plant Residues - an overview ScienceDirect Topics

Plant residues provide the major source of SOM, and their biodegradation is critical to ecosystem productivity. Because plants typically contain up to 60% cellulose (Kögel-Knabner, 2002), the decomposition of cellulose is a key activity of soil bacteria and is vital to the energy flow through soils and the cycling of N, P, and S, where immobilization generally accompanies cellulose decomposition.

Feb 02, 2021  Previous studies have shown that miR172 and its targets play critical roles in plant developmental transitions [26–29]. miR172 acts downstream of miR156, a miRNA in which the level gradually decreases with time after seed germination [30,31]. Accordingly, miR172 shows a temporal expression pattern that is the opposite of that of miR156 .

The impact of plant residues on CO2, N2O emission is dependent upon the quality of the residue (e.g., C:N ratio, N concentration) and the size of residue. The amount of N2O evolved varies among type of residue incorporated and the particle size of the residue (Ambus et al., 2001; Shelp et al., 2000).
