Attractants for automated emission measurement (Greenfeed®) in pasture-based systems. Repositório Alice
MOMBACH, M. A.; CARVALHO, P. de; CABRAL, L. da S.; RODRIGUES, R. de A. R.; TORRES, R. C.; PEREIRA, D. H.; PEDREIRA, B. C. e.
This study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.

Beyond conservation agriculture. Repositório Alice
GILLER, K. E.; ANDERSSON, J. A.; CORBEELS, M.; KIRKEGAARD, J.; MORTENSEN, D.; ERENSTEIN, O.; VANLAUWE, B..
ABSTRACT: Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil...

When enough should be enough: improving the use of current agricultural lands could meet production demands and spare natural habitats in Brazil. Repositório Alice
STRASSBURG, B. B. N.; LATAWIEC, A. E.; BARIONI, L. G.; NOBRE, C. A.; PORFIRIO-DA-SILVA, V.; VALENTIM, J. F.; VIANNA, M.; ASSAD, E. D..
Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems. However, few investigations have shown the extent to which these lands can meet projected demands while considering biophysical constraints. Here we investigate the improved use of...
