Concentration is not enough to evaluate

2016-2-15 · 1. Introduction. Wetland plants can accumulate heavy metals and nutrients and due to their vigorous growth and high aboveground biomass, they represent a suitable tool for heavy metals and nutrients sequestration and phytoremediation (e.g., Johnston, 1991, Tanner, 2001; Browning and Greenway, 2003, Lesage et al., 2007, Vymazal et al., 2009, Galletti et al., 2010, Di Luca et al., 2011).

Concentration is not enough to evaluate

Concentration of nitrogen and phosphorus is always higher in leaves than in stems. However, the stem biomass is often much higher in robust emergent species such as Phragmites australis and therefore, more nutrients can be stored in stems. The examples shown in this communication clearly reveal that to evaluate properly the accumulation of ...

Soil pH and the Availability of Plant Nutrients |

It has been determined that most plant nutrients are optimally available to plants within this 6.5 to 7.5 pH range, plus this range of pH is generally very compatible to plant root growth. Nitrogen (N), Potassium (K), and Sulfer (S) are major plant nutrients that appear to be less affected directly by soil pH than many others, but still are to ...

Resorption proficiency and efficiency of leaf nutrients

INTRODUCTION. Foliar nutrient resorption is an important mechanism of plant nutrient conservation (), being especially significant for perennial plants.As leaf senesces, parts of the nutrient components (e.g. ~50% of the total leaf nitrogen [N] and phosphorus [P]) of the hydrolysed proteins, enzymes, lecithin and nucleic acids will be re-translocated to seeds, roots and other live parts of plants.

Mechanisms of plant competition for nutrients, water

In general, nutrients, water and light are the three main classes of resources that limit plant growth and are considered to be resources for which individual plants compete. The concentration of atmospheric CO 2 can also limit plant growth, but because the atmospheric pool of CO 2 is so large and so well mixed, plants are not thought to ...
