Implement development for SAT Alfisols

Field operations in Alfisols and related soils require timeliness and precision for the early establishment of a crop in the rainy season. Animal-drawn, multipurpose wheeled tool carriers (WTCs) have been found to be the most appropriate machinery for this purpose. Three designs discussed in this paper covered 1 ha in 3-4 hours for different tillage operations, and could be drawn by a pair of oxen of average size. A WTC fitted with a planter-and-fertilizer applicator, consisting of an inclined plate for seed metering and1416 oscillating mechanisms for fertilizer metering and a double-shoe furrow opener, gave excellent results in sowing various crops, and covered 1 ha in 4-5 hours with an average draft of 1530 N (156 kgf) for four rows. A rolling crust breaker, developed to enhance seedling emergence through the surface crust, gave good results. Intensive primary tillage of Alfisols showed advantages in the early stages of crop growth, but they tended to disappear late in the season. Results of tillage studies conducted for 4 years indicate a need for further research to find out the comparative advantages of different intensities of primary tillage during the cropping season and off-season

A comparison of moldboard plows for dry season tillage of vertisols

Performance of five moldboard plows was compared during primary tillage in a dry Vertisol. The Kirloskar plow, which is commonly used on Vertisols in India, had the highest pull requirement; a sod bottom Brazilian plow had the next highest pull requirement, followed by the Triplex and ICRISAT plows. The general purpose Mouzon plow was the easiest to pull. The Kirloskar plow created the roughest surface but in general the differences between plows in their effects on surface roughness and clod size are in practice probably not important for Vertisol

Knowledge Flows and Influence in Online Social Networks: Proposing a Research Agenda

Online social networks, which have been defined as aggregated organizations that emerge from the Internet when people carry on public discussions, are increasingly becoming the vehicle of influence in social, political and economic discourse. Yet, despite its increasing importance, the nature of influence in online social networks is not really understood. Practitioners openly admit that they lack the experience to make sense of the phenomenon, and extant theory of influence in networks, which extrapolates from observations of the real world, is demonstrably inadequate when it comes to explaining influence online. The paper introduces a novel approach to analyzing influence online, which is based on the premise that knowledge flows rather than connectivity or position determine loci and regions of influence. The authors propose an exploratory, longitudinal population study of 100 highly diverse online social networks. The study will 1) benchmark a set of metrics for influence in these networks to determine which metrics are best suited for measuring influence in a plethora of contexts; 2) characterize the nature and properties of knowledge flows within each network; and 3) determine how knowledge flows impact the (virtual) spatial and temporal distribution of influence within that network
