Hydrophilic Gel Amendments to Sand Soil Can Increase Growth and Nitrogen Uptake Effi ciency of Citrus Seedlings
We tested the hypothesis that amendments of two hydrophilic gels to a sand soil would reduce N leaching losses and increase growth of citrus seedlings. Three-month-old seedlings of ̒ Swingle ̓citrumelo [Citrus paradisi Macf. xPoncirus trifoliata (L.) Raf.] were transplanted into containers of steam-sterilized Candler sand, amended with a linear acrylamide/acrylate copolymer (PAM), and/or a cross...
متن کاملSoil temperature, nitrogen concentration, and residence time affect nitrogen uptake efficiency in citrus.
We try to elucidate which environmental and soil factors control nitrogen uptake efficiency in citrus. Effects of residence time and nitrogen (N) concentration (three 500-mL applications of 7 mg N L(-1), representative of reclaimed water used for citrus irrigation in central Florida, or one 150-mL application of 70 mg N L(-1)) on nitrogen uptake efficiency (NUE) of young citrus seedlings were s...
متن کاملFertigation Frequency Affects Growth and Water and Nitrogen Use Efficiencies of Swingle Citrumelo Citrus Rootstock Seedlings
We determined if frequency of application of irrigation water plus fertilizer in solution (fertigation) could modify root and shoot growth along with growth per unit nitrogen (N) and water uptake of seedlings of the citrus rootstock Swingle citrumelo growing in a greenhouse. In the first experiment, all plants received the same amount of water with sufficient fertilizer N but in three irrigatio...
متن کاملCitrus Water Uptake Dynamics on a Sandy Florida Entisol
Florida citrus trees must be irrigated to reach maximum production due to low soil water-holding capacity. In a highly urbanizing state with limited water resources, improved understanding of soil water uptake dynamics is needed to optimize irrigation volume and timing. The objectives of this study were: (i) estimate mature citrus daily evapotranspiration (ETc) from changes in soil water conten...
متن کاملHigh-affinity potassium uptake in seedlings of two citrus rootstocks Carrizo citrange (Citrus sinensis [L.] Osb. × Poncirus trifoliata [L.] Raf.) and Cleopatra mandarin (Citrus reshni Hort. ex Tanaka)
Plant growth and K influx responses to K supply were studied in two citrus rootstocks (Carrizo citrange, Citrus sinensis [L.] Osb. × Poncirus trifoliata [L.] Raf.; Cleopatra mandarin, Citrus reshni Hort. ex Tanaka) to determine mechanisms of K acquisition. Seedlings of Carrizo citrange (CC) and Cleopatra mandarin (Cleo) were grown in aerated nutrient solutions for 40 days with either no K added...
