Organic residues management (ORM) alter plant traits and soil properties by changing nutrient and carbon cycling.It is unclear how ORM (mulching, compost, and their combination) applied for 18 months creates a mechanism to promote changes in a P.pyrifolia field.Our aim SAGE was to evaluate the influence of ORM on P.
pyrifolia nutritional status, plant traits, yield, and carbon sequestration in a 16-year subtropical P.pyrifolia field.For this purpose, we performed an experiment in a randomized block design, using a factorial scheme 2 × 2, with the use of Compost and Mulching (e.g.
, presence and absence).The highest values of leaves N content, plant height, stem biomass, root biomass, total biomass, yield, and above- and belowground carbon (C) density were found on plots that received compost as the ORM.For soil organic C stock, the highest values were found on plots where mulching was applied.Finally, the highest values of total C density were found on plots that received the combination of Mulching and Compost.
Our findings suggest that: (i) the use of Compost is the best alternative to promote leaves N content, plant height, stem dry biomass, root dry biomass, and total dry biomass, plant yield, and above- and belowground C density into a Safety Grab Bars 16-year P.pyrifolia field into subtropical conditions; and (ii) the soil organic C stocks were improved using just the mulching treatment.The results highlight the importance of considering just one organic residue practice based on a sustainable way to improve both plant production and carbon sequestration, no differences were found between the use of compost and the combination of compost and mulching.
