ABSTRACT.
Cover crops can reduce the dependence of farmers on agrochemicals while enhancing overall agrosystem?s performance. However, the inherent complexity of cover-crop-based systems hampers their adoption by conventional farmers. Therefore, special management skills and alternative research and technology transfer approaches may be required to facilitate their adoptive use by conventional farmers. We propose that development and adoption of suitable cover-crop-based production systems may require the use of an ?innovation framework? that includes (1) identification of system constraints, (2) analysis of system behavior, (3) exploration of alternative systems, and (4) system design and selection. We describe case studies from four regions of the Americas (Florida, USA; Paraná and Santa Catarina, Brazil; and Canelones, Uruguay) that illustrate the relationships between this innovation framework and the development and adoption of cover-crop-based production systems. Where successful, development and adoption of such systems appear to relate to a number of attributes including (1) active involvement by farmers in research and dissemination programs; (2) integration of cover crops into production systems without net loss of land or labor resources; (3) informing farmers of the (direct) benefits of cover crop use; (4) provision of multiple benefits by cover crops, (5) sufficient access to information, inputs, and technologies required for cover crop use; and (6) provision of skills and experience necessary to manage cover crops effectively. Where these attributes are absent and failure to innovate has prevented development and adoption of cover-crop-based systems, policy initiatives to reward farmers for ecological services provided by cover crops may be required.

Establishment of the rumen microbiome can be affected by both early-life dietary measuresand rumen microbial inoculation. This study used a 2 × 3 factorial design to evaluate theeffects of inclusion of dietary fat type and the effects of rumen inoculum from differentsources on ruminal bacterial communities present in early stages of the lambs? life. Twodifferent diets were fed ad libitum to 36 pregnant ewes (and their lambs) from 1 month pre-lambing until weaning. Diets consisted of chaffed lucerne and cereal hay and 4% molasses,with either 4% distilled coconut oil (CO) provided as a source of rumen-active fat or 4%Megalac®provided as a source of rumen-protected fat (PF). One of three inoculums wasintroduced orally to all lambs, being either (1) rumen fluid from donor ewes fed the PF diet;(2) rumen fluid from donor ewes fed CO; or (3) a control treatment of MilliQ-water. Afterweaning at 3 months of age, each of the six lamb treatment groups were grazed in spatiallyseparated paddocks. Rumen bacterial populations of ewes and lambs were characterisedusing 454 amplicon pyrosequencing of the V3/V4 regions of the 16S rRNA gene. Speciesrichness and biodiversity of the bacterial communities were found to be affected by thediet in ewes and lambs and by inoculation treatment of the lambs. Principal coordinateanalysis and analysis of similarity (ANOSIM) showed between diet differences in bacterialcommunity groups existed in ewes and differential bacterial clusters occurred in lambsdue to both diet and neonatal inoculation. Diet and rumen inoculation acted together toclearly differentiate the bacterial communities through to weaning, however the micro-biome effects of these initial early life interventions diminished with time so that rumenbacterial communities showed greater similarity 2 months after weaning. These resultsdemonstrate that ruminal bacterial communities of newborn lambs can be altered by mod-ifying the diet of their mothers. Moreover, the rumen microbiome of lambs can be changedby diet while they are suckling or by inoculating their rumen, and resulting changes in therumen bacterial microbiome can persist beyond weaning MenosEstablishment of the rumen microbiome can be affected by both early-life dietary measuresand rumen microbial inoculation.
