Salinity can be a greater problem in shallow soilless media than in field soils because of the small root zone volume that commonly occurs in such systems. Clonal integration (the capability of reciprocal resource translocation among interconnected p

To reduce nitrate contamination of groundwater in intensive agricultural production areas, crop producers should identify nitrogen (N) inputs and outputs to calculate potential N available for leaching into groundwater. However, poor understanding of

To test the hypothesis that the effect of daily root zone temperature (RZT) variations would affect strawberry plant performance, root systems of Control ‘Albion’ strawberry plants Treatment 1 (T1) were maintained at 20 °C (no stress), while pla

Many studies have shown the importance of air-filled porosity (VA ) for optimal growth and dry weight of container-grown plants, but few have examined its effects on California native plants. Anecdotal evidence suggests that various upland native spe

Site-specific fertigation can limit fertilizer waste and loss to the environment, but is not easily implemented when there are many small hydrozones, each demanding a unique rate of fertilizer application. With a simple and inexpensive fertilizer inj

Commercial greenhouse cut rose plants commonly have shallow root systems, even in well-drained substrates. We studied rose plant responses to a wide range of soil air-filled porosity values to determine tolerance to low soil aeration. ‘Kardinal’

We determined the critical nitrogen (N) level on greenhouse-grown winter creeper (Euonymus fortunei Hand. Mazz. ‘Colorata’) in one-gallon containers by adding N in doses of 0 to 400 mg/pot as ammonium nitrate (NH4NO3) and growing plants for 50 da

Production nurseries may be significant sources of nutrients and pesticides in runoff as a result of the intensity at which fertilizers, pesticides, and irrigation water are applied. Concentrations of nutrients and pesticides in runoff from productio
