Ano: 1985 URL: http://eprints.nwisrl.ars.usda.gov/448/1/566.pdf Clinoptilolite Zeolite Influence on Inorganic Nitrogen in Silt Loam and Sandy Agricultural Soils NWISRL Tarkalson, D.D.; Ippolito, J.A.. Development of best management practices can help improve inorganic nitrogen (N) availability to plants and reduce nitrate-nitrogen (NO3-N) leaching in soils. This study was conducted to determine the influence of the zeolite mineral Clinoptilolite (CL) additions on NO3-N and ammonium-nitrogen (NH4-N) in two common Pacific Northwest soils. The effects of CL application rate (up to 26.9 Mg ha-1) either band applied or mixed with a set rate of nitrogen (N) fertilizer on masses of NO3-N and NH4-N in leachate and soil was investigated in a column study using a Portneuf silt loam (coarse-silty mixed mesic Durixerollic Caliciorthid) and a Wolverine sand (Mixed, frigid Xeric Torripsamment). All treatments for each soil received a uniform application of N from... Tipo: Article Palavras-chave: Practical farm efficiency; Nitrogen; Soil.

Ano: 1978 URL: http://eprints.nwisrl.ars.usda.gov/352/1/425.pdf Flo-Thru Gated Pipe May Lower Cost NWISRL Humpherys, Allan S.. With increasing energy and labor costs, irrigators are looking for ways to minimize costs and at the same time use their water more efficiently. One system used quite extensively during the past two or three years in the Grand Valley of Colorado is the semiautomated "flo-thru" gated pipe system. This system uses a single gated pipeline for a number of irrigation sets without the irrigator having to close one group of gates and open another group at each irrigation set change.
