postharvest quality ( Conrado et al., 1980 ; Durkin, 1979 ). It is well known that vase solution can influence the populations of yeast, bacteria, and fungi, leading to vascular blockage, thus preventing water uptake, and decreasing the longevity of cut
used. To critically analyze plant fertilizer needs relative to potential water quality threats, an understanding of nutrient budgets, especially in relation to fertilizer inputs and losses in urban landscapes, is needed. Fertilization mismanagement of
Dissolved oxygen (DO) is the free oxygen available in solutions and is consumed in the metabolism of all aerobic organisms. DO concentration in water is used as an indicator of the health of ecosystems, and it varies with solution temperature
pecan trees, little to none exists on the effects of irrigation delivery system on nutrient uptake in pecan trees. Neilsen et al. (1995) investigated the effects of emitter (jet or microsprinkler) and frequency of irrigation and their effects upon
uptake. This suggests that the influence of perlite on plant growth was largely unrelated to plant nutrition and more likely due to its influence on irrigation and water relations of the media. In contrast, peat increased plant growth relative to coir in
decomposed peatmoss, derived from sphagnum peat, has historically been used for production of container-grown plants. High water holding capacity, high ion exchange capacity, resistance to decomposition, and relative abundance of peat bogs in the northern
during storage. The objectives of the present investigation were to 1) study effects of harvesting at different times of the day on water uptake, changes in fresh weight, termination symptoms, LRWC, carbohydrates status, and vase life of cut ‘ABC Purple
plant uptake, it is probably not necessary for Ca and Mg nutrition, considering the concentration already present in most irrigation water and pine bark substrates. The relatively high levels of Ca 2+ and Mg 2+ in irrigation water and substrates
immediate and well documented. The objective of this article is to examine the PA and variable rate technologies that can be used to maximize nutrient and water uptake efficiency in horticultural crops by keeping water and nutrients in the root zone
majority of those experiments were conducted was neutral or near neutral, between 6.2 and 7.4. However, the pH of nursery and greenhouse runoff is much more variable. Argo et al. (1997) conducted a geographical analysis of irrigation water applied to
