Induced technical and institutional change in tropical agriculture
The author employs a model in which the direction of technical change is induced by changes in relative resource endowments to interpret the trajectories of technical change in both developed and developing country agriculture. An international agricultural research system, an institutional innovation supported by the Consultative Group on International Agricultural Research (CGIAR), has become ...

The essential oils in agriculture as an alternative strategy to herbicides: a case study
In this study we investigated the allelopathic effect of some essential oils extracted from aromatic plants to inhibit weed seed germination. The study was performed to evaluate the potential genotoxic effect of lavender on Vicia faba root meristems by genotoxicity tests (comet assay and micronuclei test) and to evaluate microbial diversity fluctuation by Restriction Fragment Length Polymorphism ...

Bi-On, a product suitable for use in organic agriculture
Bi-On, a product suitable for use in organic farming Ecological, organic or biological agriculture is a cultivation system based on the optimum use of natural resources without using synthetic chemicals or genetically modified organisms (GMOs), thus being able to produce organic foods, as well as preserving the fertility of the soil and respecting the environment. All this in a sustainable, ...

Disc and Drum Mower Blades: Blade Safety Case Study
When in the process of operating most types of agricultural harvesting equipment, the safety of the operator, as well as bystanders, must be of utmost importance. This is especially true for disc and drum agricultural mowing equipment. Disc and drum mowers cut the crop in preparation for harvest utilizing the “blade impact” method—similar to how a lawn mower blade cuts the grass ...

Soil Microbial Community Response to Land Use Change in an Agricultural Landscape of Western Kenya
Tropical agroecosystems are subject to degradation processes such as losses in soil carbon, nutrient depletion, and reduced water holding capacity that occur rapidly resulting in a reduction in soil fertility that can be difficult to reverse. In this research, a polyphasic methodology has been used to investigate changes in microbial community structure and function in a series of tropical soils ...

Agroecology Taps a Wellspring of Farming Knowledge
Agroecology shares family farmers' evolving knowledge — and should go mainstream, says Fernando R. Funes-Monzote. Over recent decades, formal research and extension, led by governments and big enterprises, have led to novel answers for emerging problems in agriculture. However, these have generally failed small-scale farmers — one fifth of the world's population. Every day, ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

The Arkansas irrigation yield contest
Most farmers are familiar with contests in which participants try to achieve the maximum yield of a crop from a given field. Fewer would be familiar with a contest in which participants’ total crop yield is divided by the amount of water they use—thus measuring their water use efficiency. That’s the kind of contest that Dr. Chris Henry and his colleagues at the University of ...
