Nematodes in dryland field crops in the semiarid pacific northwest United States.
Soils and roots of field crops in low-rainfall regions of the Pacific Northwest were surveyed for populations of plantparasitic and non-plant-parasitic nematodes. Lesion nematodes (Pratylenchus species) were recovered from 123 of 130 non-irrigated and 18 of 18 irrigated fields. Pratylenchus neglectus was more prevalent than P. thornei, but mixed populations were common. Population densities in ...
متن کاملAdvances in Dryland Farming in the Inland Pacific Northwest
Soil amendments can improve the sustainability of agricultural systems by building soil carbon and improving numerous other soil health indicators, including soil structure, water infiltration and retention, bulk density, nutrient availability, and microbial activity. This chapter covers some general considerations relevant to the use of soil amendments followed by a discussion of biosolids, an...
متن کاملBiomass and CPUA Estimation and Distribution Pattern of Saurida tumbil from Northwest of the Persian Gulf
This paper reports on the results of a trawls survey in 2011 to assess the amount of biomass and Catch Per Unit of Area (CPUA) as well as to determine the distribution pattern of Synodontidae family of demersal fishes (with emphasize on great lizardfish, Saurida tumbil) as one of the most important and commercial fish species in the northwest of the Persian Gulf. Samples were collected fr...
متن کاملProjected Dryland Cropping System Shifts in the Pacific Northwest in Response to Climate Change
Agriculture in the dryland region of the Inland Pacific Northwest (IPNW, including northern Idaho, eastern Washington and northern Oregon) is typically characterized based on annual rainfall and associated distribution of cropping systems that have evolved in response to biophysical and socio-economic factors. Three agro-ecological classes (AEC) have been proposed for the region: (a) crop/fallo...
متن کاملRoot biomass and shoot to root ratios of perennial forage crops in eastern Canada
Bolinder, M. A., Angers, D. A., Bélanger, G., Michaud, R. et Laverdière, M. R. 2002. Root biomass and shoot to root ratios of perennial forage crops in eastern Canada. Can. J. Plant Sci. 82: 731–737. Shoot to root ratios (S:R) at peak standing crop are commonly used to estimate the annual crop residue C inputs to the soil from the root biomass left in the soil at harvest. However, root biomass ...
