Aboveground Biomass, Carbon Sequestration, and Yield of Pyrus pyrifolia under the Management of Organic Residues in the Subtropical Ecosystem of Southern Brazil

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