Pasturelands, often degraded, represent most of the converted lands globally. It is important to understand how different pasture management approaches can improve soil quality, increase feed production and farmer income. Here, the impact of different soil enhancers on soil quality and productivity of three cultivars of Brachiaria (Syn. Urochloa) forage grass is presented. Soil enhancers included: biochar - a carbon-rich product from biomass pyrolysis, moinha (local charcoal residue), traditional fertiliser containing nitrogen, phosphorus and potassium, lime, and forage peanut (Arachis pintoi cv. Amarillo). Considering the total biomass produced over the experiment (sum of four harvests), the highest dry biomass production was observed for Brachiaria brizantha cv. Piatã (14.1 Mg ha-1) and cv. Marandu (12.7 Mg ha-1), for biochar application of 30 Mg ha-1. Paiaguás had the highest dry matter production (12.4 Mg ha-1) for the treatment with forage peanut plus 15 Mg ha-1 of biochar. The increases in dry mass production translated to additional income, as compared with the control, of U$ 1 291, U$ 1 183 and U$ 991 per year for Marandu, Piatã and Paiaguás, respectively. The increases in forage grass productivity were reflected by positive changes in soil characteristics such as improvement in cation exchange capacity, pH and nutrient contents. Improved management of tropical pasturelands holds opportunity for more sustainable food production, and for ecosystem services protection and recuperation, for example, biodiversity net-gain, water regulation and carbon sequestration.

Coastal plains are characterized by low-elevation and small altitude variation and occupy an area of 57 million km2 worldwide. Ancient coastal plains that occur in the State of Rio de Janeiro (RJ), Brazil, have their pedological diversity neglected due to the generalization of some soil classes, underestimating the diversity of soils in these regions, hence limiting the evaluation for use and management. The aim of this study was to characterize the diversity of soils in a toposequence along an ancient coastal plain and to understand the pedogenetic processes involved. For this, soil pits were opened in the lower third (P1), middle third (P2), upper third (P3) and at the top (P4) of a toposequence. Soil profiles were characterized for morphological, physical, chemical, mineralogical and micromorphological properties. Profile P1 was classified as Planosol, being formed from colluvial sediments. In this profile, a lithological discontinuity was identified based on the irregularity of the values of silt/clay and coarse sand/fine sand ratios in subsurface. In this profile, limited drainage conditions were also observed. The main formation processes identified were ferrolysis and clay eluviation/illuviation, which promoted the increase of the textural gradient and thickening of the E horizon. Profiles P2 and P3 were classified as Ferralsols, were kaolinitic, with no redox conditions, and with predominance of eluviation/illuviation processes associated with pedoturbation, with a small increment of clay in the subsurface in both profiles. In profile P2, more so than in P3, there was still a strong influence of colluvial sediments, identified by the presence of a lithological discontinuity. For profile P4, a Plinthosol, located at the top of the toposequence, its formation was related to the action of weathering on the underlying acidic granite-gneiss rock. Despite the presence of plinthite, which denoted the occurrence of plinthization, the micromorphological description made it possible to state that it was a relictual condition whose formation occurred under past climatic conditions with higher water table level and which is currently being destroyed.
