The aim of this study was to assess the effect of soil management and planting spacing on establishment performance of mixed swards of purple stargrass (Cynodon nlemfuensis cv. BRS Lua) and forage peanut (Arachis pintoi cv. Belmonte). The treatments comprised two methods of soil management (conventional tillage, with desiccation followed by harrowing; and no-tillage, with sequential desiccation with glyphosate) and two planting spacing (50 and 100 cm between rows). The experimental design was in randomized blocks, arranged in split-plot. Both methods of soil management ensured rapid pasture establishment, with canopy cover greater than 94 % at 84 d after planting, with the no-tillage surpassing the conventional tillage, and at a cost of no-tillage 7 % lower. Reducing planting spacing from 100 cm to 50 cm accelerated canopy cover and reduced weed incidence. The initial contribution of forage peanut in the botanical composition was relatively small, declining by 3.8 % on average at 36 d after planting to less than 1.2 % at 84 d. No-tillage was as efficient in establishing mixed swards as conventional tillage. |

ABSTRACT. Land-use changes across distant places are increasingly affected by international agricultural trade, but most of the impacts and feedback remain unknown. The telecoupling framework - an analytical tool for examining socioeconomic and environmental interactions over distances - can be used to conceptualize the impacts of agricultural trade on land-use change and feedbacks across borders of importing and exporting countries and across spatio-temporal scales of land systems. We apply the framework to design an agent-based model (TeleABM) that represents land-use changes in telecoupled systems to investigate how local landuse changes are affected by flows. The Brazil-China telecoupled soybean system is used as a demonstration. With examples of research questions, we explore the possible applications of this model for assessing farm-level income, fertilizer usage, deforestation, and agricultural intensification, as a tool to quantify socio-ecological impacts between distant places and holistically inform sustainable land-practices across system boundaries. |
