“…Tolley-Henry and Raper (1986) reported that N deficiency reduced shoot:root ratio in soybean (Glycine max L.) grown for 25 d in Ndeficient hydroponic solution; however, Boussadia et al (2010) reported no effect on shoot:root ratio in two hydroponically grown olive (Olea europaea L.) cultivars after 58 d of N deficiency. Our results, in conjunction with those of Boussadia et al (2010), Mattson andLieth (2008), andTolley-Henry andRaper (1986), suggest that growth in the shorter production cycles of herbaceous plants is more sensitive to N deprivation than growth in relatively longer production cycles of woody plants.…”

“…Shoot mass followed a trend similar to root mass, decreasing with increasing time of N deprivation with over 67% reduction of shoot mass for plants grown without N for 26 d. Although foliar chlorophyll and N concentration recovered from longer periods in N growth solution, geranium growth was reduced and failed to completely recover for any plant receiving more than 2 d of N-free solution. Mattson and Lieth (2008) showed that rose (Rosa spp.) was not reduced in growth after 20 d of N-free solution.…”

Nitrogen (N) fertilization recommendations to achieve optimum growth are well established for many floriculture crops. Although it has been shown that plant functions can recover from N deficiency in other crops, little research has investigated the threshold beyond which a bedding plant crop is recoverable. The objective of this research was to determine the effect of N deficiency on geranium chlorophyll content and growth and then to document the degree of recovery and recovery time from N deprivation. This was determined in two experiments by monitoring chlorophyll content and growth of seedlings grown in hydroponic culture in which the N source was removed and then restored after differing lengths of time. Summarizing across both experiments, chlorophyll and foliar N levels were shown to rebound quickly after N deprivation; however, growth was reduced after just 4 days compared with plants fed constantly. Geraniums grown without N for 4 to 12 days resulted in smaller, more compact plants with lower shoot–to-root ratios. Although foliar chlorophyll and N concentration recovered from longer periods in N growth solution, geranium growth was reduced and failed to completely recover for any plant receiving more than 2 days of N-free solution.

In order to reduce nutrient wastes to the environment the supply should be in accordance to the demand for these. Two experiments were conducted to study and quantify the effect of temperature, irradiance, and plant age on the uptake of nitrate (NO 3 -), ammonium (NH 4 + ), dihydrogen phosphate ion (H 2 PO 4 -), potassium (K + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), and sulfate (SO 4 2 ). In the first experiment, various levels of temperature and irradiance were applied to plants in a growth chamber, while in the second experiment the uptake was studied along the crop season under greenhouse conditions. The uptake rates were calculated at 2-hour intervals through sampling the nutrient solution and analyzing it by inductively coupled plasma atomic emission spectrometry (ICP-AES). Increasing light and temperature enhance the uptake rates, while the rates decrease with plant age. Nitrogen absorption was similar during the day as during Downloaded by [New York University] at 08:30 21 July 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 the night. No differences were found in the absorption of H 2 PO 4 -, K + , Ca 2+ , Mg 2+ , and SO 4 2-between day and night. Nitrate absorption was found to have a positive correlation with the absorption of all the ions except for NH 4 + .

“…As new flower shoots reach maturity and become net exporters of carbohydrates, the root system recovers as does N uptake. Nutrient demand also depends on several other parameters including: cultivar (Kelly et al, 2000;Sharifi and Zebarth, 2006;Teo et al, 1992), environmental conditions (Wheeler et al, 1998), the nutritional history of the plant (Mattson and Lieth, 2008a;Subasinghe, 2006;Wheeler et al, 1998), and plant health as affected by abiotic and biotic stresses (Walters and Ayres, 1980). A 4-fold difference in the maximum rate of nitrate (NO 3 ) accumulation by roots was noted between cultivars of red maple (Acer rubrum) seedlings grown under the same conditions (Kelly et al, 2000).…”

“…Wheeler et al (1998) found that growing lettuce plants under varying light levels and NO 3 concentrations affected relative growth rate, which in turn affected plant nutrient demand. Rose plants deprived of N, phosphorus (P), or potassium (K) for up to 20 d exhibited increased absorption of the specific nutrient that was lacking as compared with control plants that had been provided with sufficient nutrients (Mattson and Lieth, 2008a). For N and P, deprived plants showed a 2-fold increase in uptake rates when those nutrients were subsequently introduced as compared with control plants; K deprived plants showed an enhanced affinity for absorbing K at low concentrations.…”

Application of the “4R” Nutrient Stewardship Concept to Horticultural Crops: Applying Nutrients at the “Right Time”

The 4R nutrient stewardship framework presents four concepts to consider when applying fertilizers in a responsible matter; the “right source” of nutrients should be applied at the “right rate” during the “right time” and supplied to the “right place” to ensure their uptake. In this article, we provide ideas to consider when attempting to provide nutrients at the right time. When nutrients are applied at a time when they are not required by the plant, the result can be economic and environmental losses. Oversupply relative to plant demand can result in losses of applied nutrients because of leaching or volatilization. Undersupply relative to demand, especially in the case of phloem-immobile nutrients, may limit plant growth and yield. Several factors interact to affect plant nutrient demand such as growth stage, life history (annual vs. perennial), environmental conditions, and plant health. Techniques such as soil and tissue testing, isotopic labeling, and spectral reflectance have been used with varying degrees of success and expense to measure plant nutrient demand and guide fertilizer decisions. Besides knowledge of plant nutrient demand, efficient nutrient supply also depends on systems that allow precise spatial and temporal delivery of nutrients. Future improvements to the timing of nutrient delivery will depend on improvement in knowledge of plant nutrient demands. For example, targeted gene expression chips show promise for use in rapidly assessing plant status for a broad suite of nutrients. Future developments that allow more precise nutrient delivery or more robust agroecosystems that scavenge available nutrients before they are lost to the environment will also help producers use nutrients more efficiently.
