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...

ABSTRACT This paper aims to discuss the impact of the introduction of pastures and grazing animals in agricultural systems. For the purposes of this manuscript, we focus on within-farm integrated crop-livestock systems (ICLS), typical of Southern Brazil. These ICLS are designed to create and enhance the synergisms and emergent properties have arisen from agricultural areas where livestock activities are integrated with crops. We show that the introduction of the crop component will affect less the preceding condition than the introduction of the livestock component. While the introduction of crops in pastoral systems represents increasing diversity of the plant component, the introduction of animals would represent the entry of new flows and interactions...

Soil Physical Quality in Agricultural Systems on the Cerrado of Piauí State, Brazil Anais da ABC (AABC)
SCHOSSLER,THIAGO R.; MARCHÃO,ROBÉLIO L.; SANTOS,ISIS L. DOS; SANTOS,DJAVAN P.; NÓBREGA,JÚLIO CÉSAR A.; SANTOS,GLENIO G..
Abstract Soil quality is essential for maintaining the sustainability of agro-ecosystems and ecosystem services provided by this natural resource. The present study aimed to assess the physical quality of soil through the characterization of the physical properties in grain production systems in the Southwest region of Piauí State, Brazil. The study was carried out in the Cerrado region of Piauí in four cities in areas of expansion of the agricultural frontier of the state: Baixa Grande do Ribeiro, Sebastião Leal, Uruçuí and Bom Jesus. Soil samples were collected in April 2012, in areas of grain production under conventional and no-tillage systems. Adjacent areas with native vegetation were also sampled as reference. Bulk density, effective saturation,...

Strategic grazing management and nitrous oxide fluxes from pasture soils in tropical dairy systems. Repositório Alice
CONGIO, G. F. S.; CHIAVEGATO, M. B.; BATALHA, C. D. A.; OLIVEIRA, P. P. A.; MAXWELL, T. M. R.; GREGORINI, P.; SILVA, S. C. da.
Greenhouse gases emissions are considered one of the most important environmental issues of dairy farming systems. Nitrous oxide (N2O) has particular importance owing to its global warming potential and stratospheric ozone depletion. The objective of this study was to investigate the influence of two rotational grazing strategies characterized by two pre-grazing targets (95% and maximum canopy light interception; LI95% and LIMax, respectively) on milk production efficiency and N2O fluxes from soil in a tropical dairy farming system based on elephant grass (Pennisetum purpureum Schum. cv. Cameroon). Results indicated that LI95% pre-grazing target provided more frequent defoliations than LIMax.Water-filled pore space, soil and chamber temperatures were...

Weed phytosociological in irrigated rice under different cultivation systems and crop rotation intensity Ciência Rural
Ulguim,André da Rosa; Carlos,Filipe Selau; Santos,Rodrigo Areze da Silva; Zanon,Alencar Junior; Werle,Isabel Schlegel; Beck,Mattheus.
ABSTRACT: This research aimed to evaluate the phytosociology of weeds in irrigated rice in different soil management systems and crop rotation intensity. Therefore, two field studies were carried out. Study 1 was conducted in an area that has been cultivated since 1994 with three cultivation systems: direct, pre-germinated and conventional ones. Study 2 was carried out in an experimental area in five Integrated Farming Systems, with crop rotation. Phytosociological evaluations were conducted when rice was fully blooming, in the first study, and when grain filling was ending, in the second study. Pre-germinated system of rice cultivation has predominance of aquatic weeds. Conventional system when compared with direct sowing has lower weed densities....

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...
