`Supjibi' poinsettias (Euphorbia pulcherrima Willd.) were grown hydroponically for 15 weeks in nutrient solutions with 100-15-100, 200-30-200, or 300-46-300 (in mg·L-1 of N-P-K) to determine nutrient uptake patterns and accumulation rates. Results indicate that increasing fertilization rates from 100 to 300 mg·L-1 of N and K did not significantly influence the plant dry mass or the nutrient concentration of P, K, Ca, Mg, Na, B, Cu, Fe, Mn, Mo, and Zn in poinsettias. NH4-N concentration in the leaves, stems, and roots were lowest with the 100-mg·L-1 N fertilization rate and increased as the N application rate increased to 200 and 300 mg·L-1. Leaf P concentration levels from 1 week after potting through anthesis were above 1.3%, which exceeds the recommended level of 0.9%. When the plant tissue dry mass for each fertilizer rate was transformed by the natural log and multiplied by the mean tissue nutrient concentration of each fertilizer rate, there were no significant differences among the three fertilization rates when the total plant nutrient content was modeled for N, P, or K. Increasing the fertilizer application rate above 100 mg·L-1 N and K and 15 mg·L-1 P decreased total plant content of Ca, Mg, Mn, and Zn and increased the total plant Fe content. The results of the weekly nutrient uptake based on the total plant nutrient content in this study suggests that weekly fertilization rates should increase over time from potting until anthesis. Rates (in mg) that increase from 23 to 57 for N (with 33% of the total N supplied in the NH4-N form), 9 to 18.5 for P, 19 to 57 for K, 6 to 15 for Ca, and 3 to 8 for Mg can be applied without leaching to poinsettias and produce adequate growth in the northern United States.

Plant Nutrient Content

Approximately 50 million metric tons of poultry wastes are produced annually in the United States. Production of this byproduct is not without costs. Cost incurred for handling and disposal of broiler litter, for example, has been estimated to be .26c per kg of liveweight salable bird [1].Although costs are associated with this byproduct, it is not a source of revenue for many producers. The traditional use of litter has been as a fertilizer. However, for many poultry producers, land is a limiting factor. In some cases, the value of the plant nutrient content of the wastes does not justify their use instead of commercial fertilizers when handling costs are considered. Thus in many instances these wastes create a pollution problem and may be negatively priced.

Incineration of faeces offers a treatment method that is useful in reducing the final quantities of faeces and toilet paper. It is also useful as a sanitation method for faeces. The aim of this work was to increase the knowledge about incineration as a treatment and sanitation method for faeces. The faecal matter used in this study contained ash used as additive material during the collection phase. The incinerated faeces/ash mixture had an ash content of 86%. It caught fire when the temperatures reached 800°C and beyond and after this, temperatures in the range of 800 to 1000 °C were recorded. The mass reduction was 15 - 36% and the organic matter was reduced by 78 - 99%. The plant nutrient content was reduced, total nitrogen by 90 - 94% and available phosphorus by 70 - 94%. Incinerating material with a dry matter (DM) of less than 90% resulted in a strong smell. When the DM was higher, the smell lessened. The reduction in mass of excreta and the possibility to re-use ashes as additives in toilets can be advantages of incineration of faeces.
