status of plants throughout the growing season to determine whether each nutrient is present in sufficient concentrations for optimum growth characteristics. The tissue tests confirm suspected nutrient deficiency symptoms, reveal hidden hunger, and verify
11.6 mg·kg −1 ( Table 1 ). Although visual symptoms did not develop, the corresponding tissue values can be used as indicators of the lower nutrient sufficiency ranges. Discussion The observed symptoms of Ca, P, Mg, and Mn deficiencies matched
Palms are increasingly popular as landscape plants in tropical to warm temperate regions of the United States and as interiorscape plants elsewhere. While visible nutrient deficiency symptoms are relatively uncommon on dicot trees found in
Each essential element taken up by a plant serves to fulfill a specific physiological role, and reduced (nutrient deficiency) or excess (nutrient toxicity) levels of that element often result in unique symptomology that may be used for diagnostic
-containing fertilizers would result in superior growth or visual quality. Gilman et al. (2000) reported no response to applied phosphorus (P) or K in live oak, but this species rarely exhibits deficiencies of any nutrient element in the landscape. Broschat et al
rarely exhibits deficiencies of any nutrient element in the landscape. Because responses to fertilization appear to vary greatly among species and in different soils and environments, it is important to study the growth responses of individual species
measured for all plants at 4, 7, and 10 weeks after transplanting (WAT) using the pour-through method ( Wright, 1986 ). Petunia flowers and zonal geranium inflorescences were counted by removing fully opened flowers weekly. Visual nutrient deficiency
filter were also observed. Nutrient deficiency in Expt. 2 may have caused severe root necrosis for plants in the AC filter treatment, which might in turn result in insufficient macronutrient absorption and subsequently higher nutrient levels in irrigation

visual symptoms of nutrient deficiency Substrate affected substrate N concentration at the end-of-production [ P ≤ 0.01 ( Table 1 )], where N was lowest for peat:coir (118.3 ppm N) and greatest for peat (201.1 ppm N) and peat:wood (182.8 ppm N), with
