Trace element
Trace element fertilizers contain all the necessary micronutrients for plant growth in aquascaping. The most common but nonetheless essential ones are:
- Copper: It is involved in the composition of certain enzymes that participate in photosynthesis or enable cell respiration. A copper deficiency manifests on new shoots with reduced size and wilting. Leaves may become dark green and necrotize from the tip to the edges, or show deformations and a yellowish hue.
- Boron: Its deficiency causes poor seed germination, fragility of plant tissues, and bud death. An excess of boron causes the blackening of plant tissues.
- Zinc (Zn): It is a constituent of oxidation enzymes. It has a protective role with auxin, a growth hormone. A deficiency causes reduced leaf size and internode length, deformation of leaf edges, and chlorosis. An excess of zinc leads to poor magnesium assimilation.
- Manganese (Mn): An insufficiency causes chlorosis and the appearance of brown spots giving a grid-like appearance to the leaves (commonly on Echinodorus and Vallisneria). An excess of manganese manifests with symptoms similar to those of iron deficiency.
- Molybdenum (Mo): Chlorosis and leaf deformation result from a lack of molybdenum.
- Chlorine (Cl): A deficiency causes leaf wilting, browning, and root destruction.
- Cobalt (Co): This element is essential for nitrogen fixation. It is used by newly planted vegetation. Little is still known about its deficiency and toxicity.
