The objectives of our study were: (1) to quantify the effects of contrasting organic residue (OR) retention methods on tree growth and soil nutrient pools over a full  Eucalyptus  rotation and (2) to assess the potential of soil analyses to predict yields of fast-growing plantations established on tropical sandy soils. An experiment was set up in the Congo at the harvesting of the first rotation after afforestation of a native herbaceous savanna. Six treatments were set up in 0.26\u00a0ha plots and replicated in 4 blocks, with OR mass at planting ranging from 0 to 46.5\u00a0Mg\u00a0ha \u22121 . Tree growth over the whole rotation was highly dependent on OR management at planting. Over-bark trunk volume 7 years after planting ranged from 96\u00a0m 3 \u00a0ha \u22121  in the treatment with forest floor and harvest residue removal at planting to 164\u00a0m 3 \u00a0ha \u22121  in the treatment with the largest amount of OR. A comparison of nutrient stocks within the ecosystem at planting and at the end of the rotation suggested that nutrient contents in OR were largely involved in the different response observed between treatments. OR management treatments did not significantly modify most of the nutrient concentrations in the upper layers of the mineral soil. Conventional soil analyses performed before planting and at ages 1 and 3 years were unable to detect differences between treatments despite large differences in tree growth. In contrast, linear regressions between stand aboveground biomass at harvesting and OR mass at planting (independent variable) showed that OR mass was an excellent predictor of stand yield ( R  2 \u00a0=\u00a00.99). A large share of soil fertility comes from organic material above the mineral soil in highly weathered sandy soils and OR mass at planting might be used in conjunction with soil analyses to assess the potential of these soils to support forest plantations.", "keywords": ["0106 biological sciences", "570", "http://aims.fao.org/aos/agrovoc/c_7170", "[SDV]Life Sciences [q-bio]", "rendement des cultures", "Slash", "F62 - Physiologie v\u00e9g\u00e9tale - Croissance et d\u00e9veloppement", "for\u00eat tropicale", "01 natural sciences", "630", "http://aims.fao.org/aos/agrovoc/c_10176", "http://aims.fao.org/aos/agrovoc/c_24904", "sol tropical", "http://aims.fao.org/aos/agrovoc/c_16118", "http://aims.fao.org/aos/agrovoc/c_5387", "2.

The objective of this work was to understand the dynamics of soil carbon in intensively managed Eucalyptus plantations after the afforestation of a native savannah. The isotopic composition (\u03b4) of soil carbon (C) and soil CO2 efflux (F) were measured on a four-age chronosequence of Eucalyptus and on an adjacent savannah. \u03b4                         F was used to partition F between a C3 component and a C4 component, the latter corresponding to the decomposition of a labile pool of savannah-derived soil carbon (C                         SL). The mean residence time of CSL was 4.6\u00a0years. This further allowed us to partition the savannah-derived soil carbon into a labile and a stable (C                         SS) carbon pool. C                         SL accounted for 30% of soil carbon in the top soil of the savannah (0\u20135\u00a0cm), and only 12% when the entire 0\u201345\u00a0cm soil layer was considered. The decrease in C                         SL with time after plantation was more than compensated by an increase in Eucalyptus-derived carbon, and half of the newly incorporated Eucalyptus-derived carbon in the top soil was associated with the clay and fine silt fractions in the 14-year-old. stand. Increment in soil carbon after afforestation of tropical savannah with Eucalyptus is therefore expected despite a rapid disappearance of the labile savannah-derived carbon because a large fraction of savannah-derived carbon is stable.", "keywords": ["P33 - Chimie et physique du sol", "0106 biological sciences", "570", "550", "SAVANNAH", "SEQUESTRATION", "ORGANIC-MATTER DYNAMICS", "01 natural sciences", "630", "zone tropicale", "PLANTATION", "[SDV.BV]Life Sciences [q-bio]/Vegetal Biology", "EUCALYPTUS", "[SDV.BV] Life Sciences [q-bio]/Vegetal Biology", "sol tropical", "savane", "http://aims.fao.org/aos/agrovoc/c_1301", "13C", "TROPICAL PLANTATION", "http://aims.fao.org/aos/agrovoc/c_3048", "CHANGEMENT D'USAGE DES TERRES", "http://aims.fao.org/aos/agrovoc/c_35657", "Eucalyptus", "http://aims.fao.org/aos/agrovoc/c_162", "CO2 EFFLUX", "FRACTIONATION", "http://aims.fao.org/aos/agrovoc/c_1811", "LAND-USE CHANGE", "04 agricultural and veterinary sciences", "CHRONOSEQUENCE", "15.

Earthworms are known to closely interact with above-ground and under-ground soil biota and particularly with plants and microfaunal communities. This study was aimed at investigating, under greenhouse conditions, the effects of the earthworm Pontoscolex corethrurus on banana growth and nutrient uptake, and assessing the influences of this earthworm on the development of an inoculated population of R. similis. Six-week-old tissue culture banana plants were submitted to four treatments: with P. corethrurus, R. similis, P. corethrurus+R. similis, and a control with no earthworms or nematodes. At the end of the experiment, the P. corethrurus treatments showed significantly higher leaf surface areas, shoot dry root weights, and root fresh weights than those without earthworms. This root growth enhancement probably contributed to the evident but non-significant decrease in the density of nematodes in the roots, even though earthworms did not reduce the total number of nematodes per whole root system. Moreover, the presence of earthworms slightly alleviated the severity of root damage. N bioavailability in the soil, along with N, Ca, and Mg content of banana plants, were also significantly increased in the presence of earthworms. Our results demonstrated that banana plant growth and nutrition were positively influenced by earthworms.
