The cumulative ef- fect of N deprivation through the season as crop mass increased apparently resulted in the relatively greater decrease in leaf N concentration under the low soil
These include information on annual rainfall, ®nal and initial soil salinities for each growing season, seasonal irrigation amounts and water salinity, and annual yield levels..
Using a whole year’s worth of data, soil heat flux was estimated by a two-step version of the null-alignment method using soil temperature, water content and bulk density
Squared correlation coefficients (R 2 ) between estimated and measured solar radiation versus the distance between sites providing model parameters and sites for which radiation
Populus fremontii, a dominant ‘phreatophyte’ in these semi-arid riparian ecosystems, also used mainly groundwater, but at the ephemeral stream site during the summer rainy season
