“…Considerable increment in the amounts of SOC, especially due to the long-term application of compost was evident in the present experiment (Table 1). Shindo et al (2006) attributed accumulation of SOC due to compost application to improvements in the contents and composition of humus in paddy fields. Although the long-term application of any source of organic material to soils can significantly improve the fertility, the application of high amounts of soluble C (e.g.…”

“…On the time scale of several decades, in arable soils which receive high organic materials, relatively less organic matter is stabilized either by association with the silt plus clay mineral fractions, or by its inherent biochemical recalcitrance (Sleutel et al, 2006). Shindo et al (2006) reported that continuous compost application in a field subjected to 25 years of double cropping could increase both the amounts of fulvic and humic acids, and the total humus content. From the organic carbon sequestered quality standpoint, Nardi et al (2004) found that, over 40 years, farmyard manure fertilization improved by 116% the production of humus with a high degree of polycondensation, a high-quality fraction usually linked to soil fertility.…”

“…These recycled co-products may become useful to counteract the loss in quality of many soils due to an inadequate supply of organic matter or improper management, such as the loss of organic matter (Guillaume et al, 2015) or the occurrence of acidity due to ammoniumproducing fertilisers (Dubos et al, 2016). Research work undertaken on oil palm and other crops also showed that compost or organic matter application can also enhance root growth, improve soil structure and stability (Shindo et al, 2006), increase CEC and soil biological activity (Chakraborty et al, 2011), reduce iron and aluminum toxicity and significantly increase phosphorus availability in the soil (Budianta et al, 2010, Darmosarkoro andSutarta, 2002). These issues and opportunities have stressed the need to develop alternatives to conventional oil palm waste treatments, among which composting is a promising one.…”

-Palm oil is nowadays the first vegetable oil consumed worldwide. Given the world population growth and the increasing demand in fat for food and fuel, the increase in oil palm production is expected to continue. It is thus important to find ways of reducing the ecological impact of oil palm plantations at both the agroecosystem and the mill supply area levels, by improving agricultural practices and land uses. This is where agroecology can play a very critical role. The present article gathers short stories on agroecological practices currently taking place in oil palm plantations in South-East Asia. Such stories notably highlight the importance of the various palm co-products and how appropriate recycling strategies can allow for reducing external inputs to both the field and the mill. Besides limiting environmental impacts thanks to such savings, several coproducts used as organic amendments can even help to maintain or enhance soil quality. Other stories explored agroecological practices developed for biological controls. Although integrated pest management has been applied in palm plantations for a long time, the underlying mechanisms are still not fully deciphered and practices still need to be improved. More knowledge is needed in order to better account for the holistic role of biodiversity and arbitrate trade-offs between practices and ecosystem services, at both plantation and landscape levels.Keywords: palm oil / agroecology / biological control / recycling / composting / soil quality Résumé -Pratiques agroécologiques en plantations de palmier à huile : exemples de terrain. L'huile de palme est aujourd'hui la première huile végétale consommée au monde. Étant donné la croissance démographique mondiale et la demande accrue en corps gras pour l'alimentation et les biocarburants, l'augmentation de la production d'huile de palme devrait perdurer. Il est ainsi primordial de trouver des moyens de production permettant de réduire l'impact écologique des plantations de palmier à huile, à la fois à l'échelle de l'agroécosystème et celle du bassin d'approvisionnement de l'huilerie, en améliorant les pratiques et la gestion des usages des sols. Les principes de l'agroécologie peuvent aider à développer des solutions à ces diverses échelles. Cet article rassemble diverses histoires courtes illustrant des pratiques agroécologiques mises en place dans des plantations de palmier à huile en Asie du Sud-Est. Ces illustrations mettent en évidence l'importance des nombreux co-produits issus du palmier et leur rôle clé dans les stratégies de recyclage pour réduire le recours aux intrants externes pour la plantation comme pour l'huilerie. Au-delà de la réduction des impacts environnementaux du fait de ces économies d'intrants, certains co-produits restitués en plantation peuvent également permettre de maintenir, voire d'améliorer, la qualité des sols. D'autres histoires courtes parcourent quelques autres pratiques agroécologiques dans le domaine de la lutte intégrée. Bien que de nombreuses pratiques de contrôle bi...
