Introduction Compost is a soil amendment produced through the metabolism of an organic substrate—a surface on which organisms grow—by aerobic (oxygen-requiring) microbes under controlled conditions. Composting is an ancient agricultural technology going back to biblical times that still has important applications in modern agriculture. Recent years have seen a resurgence of interest in compost ...

This study estimates an econometric model that incorporates the linkages among agriculture, manufacturing, service and trade sectors using a vector error correction model for Poland and Romania. Three cointegrating vectors for Poland and one for Romania confirm that the different sectors in the Poland and Romania moved together over the sample period, and for this reason, their growth rates are...

Chlorpyrifos is registered for use in agriculture to control numerous insects on barley, wheat, oats and a wide variety of garden vegetables (Agriculture Canada and Environment Canada 1990; Agriculture and Agri-Food Canada 1997). Nonagricultural uses include the control of insect pests on turf and ornamental plants and in nonfood domestic areas, veterinary clinics, and commercial storage or pro...

Information about weather and climate is vital for many areas of decision-making, particularly under conditions of increasing vulnerability and uncertainty related to climate change. We have quantified the global commercial supply of weather and climate information services. Although government data are sometimes freely available, the interpretation and analysis of those data, alongside additio...

Introduction As successive strategy and policy papers have emphasized, agriculture is the most important economic sub-sector in Papua New Guinea. We are constantly told that agriculture provides the livelihood for about 85 per cent of the economically active population. The agriculture sector covers the activities of the private and public sector in cropping, animal husbandry, management of lan...

Using dynamic panel models with data for 62 developing countries, this paper examines whether growth in agriculture elicits growth in manufacturing. For identification, I use population-weighted, average temperature as an instrument for growth in agriculture. I identify large short-run effects: An increase in growth in agriculture by one percentage point is estimated to raise contemporaneous gr...
