How Do Management Choices Impact the Performance of Cassava‐Legume Intercropping in Africa? A Meta‐Analysis

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Intercropping can enable sustainable intensification. In Africa, smallholder farmers rely on Cassava (Manihot esculenta Crantz) as a staple food. Nevertheless, the performance of cassava intercropping emerges from management choices such as legume species selection, planting density, sowing time, and nitrogen (N) fertilisation as well as soil ...

Extraction Kinetics and Molecular Size Fractionation of Humic Substances From Two Brazilian Soils

Journal of the Brazilian Chemical Society, 1999
In the present study, the extraction behaviour of humic substances (HS) from an Oxisol and a Mollisol from South Brazil, by using 0.1 and 0.5 mol L-1 NaOH and 0.15 mol L-1 neutral pyrophosphate solutions, respectively, was systematically studied.

Organic residues and Parachlorella microalgae favor the growth and gas exchange of cedar [PDF]

Scientia Agricola
Using organic residues and bioinputs is a promising and sustainable practice to produce seedlings with forest essences, such as Cedrela fissilis Vell. (cedar), a vulnerable species close to extinction due to intensive exploitation in native areas.

Moderate Fire Temperatures Affect the Structure of Clayey Oxisol Aggregates

Land Degradation &Development, Volume 37, Issue 8, Page 3169-3181, 15 May 2026.
ABSTRACT Wildfires have become increasingly frequent and intense worldwide, raising concerns about their impacts on soil systems. However, the thermal responses of clay‐rich Oxisols, dominated by Fe and Al oxides, remain poorly understood. In this study, samples from the 0 to 5 cm layer of six Oxisols were subjected to controlled heating at ...

Stylosanthes cv. Campo Grande response to Bradyrhizobium inoculation in an Amazon Cerrado Oxisol

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Species of the genus Stylosanthes show great potential for use in mixed pastures and as green manure due to their symbiotic potential in symbiosis with diazotrophic bacteria, particularly Bradyrhizobium. These herbaceous legumes can improve pasture quality and contribute to sustainability.

Soil-atmosphere exchange of nitrous oxide, nitric oxide, methane, and carbon dioxide in logged and undisturbed forest in the Tapajos National Forest, Brazil. [PDF]

, 2016
Selective logging is an extensive land use in the Brazilian Amazon region. The soil?atmosphere fluxes of nitrous oxide (N2O), nitric oxide (NO), methane (CH4), and carbon dioxide (CO2) are studied on two soil types (clay Oxisol and sandy loam Ultisol ...

Cassava production systems optimized for double output: Seed‐cuttings and root yields

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Cassava (Manihot esculenta Crantz) is a strategic crop for food security but continues to face major challenges related to low root yields and the lack of optimized systems for producing high‐quality seed‐cuttings. This study evaluated the effects of different planting densities, varieties, and agrochemical‐based seed‐cutting treatments ...

Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.
