Nutrient removal through plant components of low yielding coconut plantation

A Comparison of Coconut Coir and Sphagnum Peat as Soil-less Media Components for Plant Growth

Investigating the efficiency and kinetic coefficients of nutrient removal in the subsurface artificial wetland of Yazd wastewater treatment plant

Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...

Nutrient Removal from Leachate

Remediation of the City of Zagreb Jakusevec Dump Site, one of the largest dump sites in Europe, is in progress. Experimental laboratory results of leach­ ate treatment using aquatic macrophytes show that increasing the concentra­ tion of ammonia in the leachate decreases elimination efficiency. In all series of experiments, significantly greater elimination of ammonia and orthophos­ phates has ...

Plant Volatiles Yielding New Ways to Exploit Plant Defence

When plants are damaged, they produce semiochemicals which can act as repellents for herbivorous pests and as attractants for organisms antagonistic to these pests, e.g., predators and parasitic wasps. Plants can also produce signals that warn other plants of impending attack. From this range of phenomena, it is possible to identify new ways to control pests. Although, in the past, we have need...
