The response of earthworm communities to farming practices was assessed in 33 farms of the Soummam valley (Algeria). Market gardening was the most intensive practice with frequent tillage (94% farms), application of chemical (94%) and organic (70%) fertilizers and pesticides (70%). Orange tree pl...

Adding biochar to soils and maintaining high earthworm biomasses are potential ways to increase the fertility of tropical soils and the sustainability of crop production in the spirit of agroecology and ecological engineering. However, a thorough functional assessment of biochar effect on plant g...

The objective of this work was to assess the effects of integrated crop-livestock systems, associated with two tillage and two fertilization regimes, on the abundance and diversity of the soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass); continuous...

In this study, we investigated the spatial distribution of an earthworm community together with the heterogeneity of selected soil properties in a gallery forest (GF) of the Colombian Llanos . We performed fine-scale spatial variability by intensively sampling 100 points distributed in the nodes...

O objetivo deste trabalho foi avaliar o efeito do uso do solo sobre a densidade e a diversidade da macrofauna invertebrada, bem como a relação dessa com atributos químicos do solo em diferentes agroecossistemas. Foram estudados cinco agroecossistemas: sistema ecológico com três anos de adoção (SE...

The effect of different types of land management on the soil macrofauna of the savanna has been assesed using the T.S.B.F. method. Macrofauna of the forest and savanna has a high density (4293 and 2830 ind.m(2)) and moderate biomass (13.6 and 15.3 g.m(-2)). Traditional grazing significantly incre...
