Pox C (labile-C) to mineralizable C ratio used to assess organic carbon dynamics in soils (Hurisso et al. 2016). Positive trends refer to SOC stabilization and negative trends to SOC mineralization.

Positive trend of C stabilization under Forest and Maize-Rice bean system in Laos, Laeng village (left), and under no-till cropping systems (DMC 1, 2a, 2b) in Cambo-dia (Conservation agriculture training center, Bos Khnor, right).

A multi-criteria approach in comparing conventional and conservation agriculture in rice-maize cropping systems in the degradable and Striga-infested soils of Central Madagascar

We recorded: (i) rice and maize yields; (ii) cumulated above-ground biomass per cropping systems; (iii) bulk density, total nitrogen, and available phosphorus (0-10cm) and;

Soil organic carbon dynamics under short-term conservation agriculture cropping systems in Cambodia

In conclusion, short-term CA practices in the three cropping systems increased the storage of STN, SOC and labile SOC pool and enhanced soil enzyme activities in the surface soils

Assessment of soil humification under conventional and no-till systems through laser-induced fluorescence and FT-IR spectroscopies

Thus, this study assessed the humification degree (HLIF) of soil organic matter (SOM) and the changes in functional C groups (aromatic-C and aliphatic-C) for contrasting land use and

Restoration of SOC pools under no-till systems in subtropical and tropical regions of Brazil

Thus, the objective of this study was to quantify changes in SOC fractions due to conversion of NV to agricultural land, and to assess the rate of recovery of SOC fractions and

Cropping system to limit blast disease in upland rice

Blast incidence was reduced in DSMB cropping system and, on the contrary to the traditional cropping system, the mineral fertilisation had no effect on blast in DSMB.. N

Soil aggregation, water-holding capacity, and biological activity under no-till systems and cropping sequences in the Lao PDR

Land preparation is based mainly on plowing, which degrades soil and destroys infrastructures (paddy fields and roads). These deteriorations result from growing pressure

Cropping system to limit blast disease in rainfed rice

The number of grains per panicles, elaborated during the « leaf blast period » was affected in the tillage crop compared to the zero tillage.. We supposed then that not only
