  abstract = {{S}oil erosion on agricultural land is a major threat for food and raw materials production. {I}t has become a major concern in rubber ({H}evea brasiliensis) plantations introduced on sloping ground. {A}lternative agroecological crop management practices must be investigated. {O}ne aim of our study was to assess the ability of logging residues (i. e., trunks, branches, leaves and stumps of a clearcut plantation) and of legume cover ({P}ueraria phaseoloides) to mitigate {N}, {P} and {K} losses through runoff and soil detachment in a young rubber plantation. {T}he other aim was to investigate the relationships of these nutrient losses with soil structure and soil macrofauna diversity. {R}unoff and soil loss were monitored for 3 years using 1-m2 plots under different practices as regards the management of logging residues and the use or not of a legume. {T}he monitoring started when rubber trees were one-year-old. {T}he planting row, where soil was bare, was the hotspot of soil erosion, with an average runoff of 832 mm y-1 and soil loss of 3.2 kg m- 2 y-1. {S}owing a legume in the inter -row reduced runoff and soil loss by 88 % and 98 % respectively, compared to bare soil. {S}preading logging residues as well as growing a legume cover almost eliminated runoff and soil detachment (19 mm y-1 and 4 g m- 2 y-1 respectively). {N}utrient losses were negligible as long as the soil surface was covered by a legume crop, with or without logging residues. {T}otal {N} loss from soil detachment ranged from 0.02 to 0.2 g m- 2 y-1, for example. {S}preading logging residues in the inter -rows significantly improved soil structure and soil macrofauna diversity compared to bare soil. {N}utrient losses from runoff and soil detachment were negatively correlated with improved soil structure and soil macrofauna diversity. {W}e recommend investigating alternative ways to manage planting rows.},
