Excessive Fertilizer Could Dry Plant Tissue


Excessive fertilizer salts is the main cause of drying roots, less flowers and fruits, according to experts.

Nitrogen, phosphorous and potassium are the most important components of fertilizers and included in almost all fertilizer. The salt component if increased in soil, the plants growth might get affected.

Symptoms such as too many leaves and too few flowers, short and stunted growth, leaves with discolored edges, and dead patches or stripes are found when the fertilizer intake is increased beyond the required dose.

The salts present in fertilizer attacks the plant tissue by drying them. Brown patches seen in grass lawns is mainly due to the damaged roots caused by excessive fertilizers. “If blooming plants get too much nitrogen, they’ll grow stems and leaves at the expense of flowers,” says Julie Janoski, manager of the Plant Clinic at the Morton Arboretum in Lisle.

Natural nutrients are sufficient for plant’s growth, as they absorb them from soil. The microorganisms helps in building the supply of nutrients to plants’ roots by breaking down leaf litter and other organic matter. However, artificial environment such as pots and small gardens need to be supplied with nutrients. Fertilizer that we add to the potted plants must be proportionately distributed throughout the soil.

Furthermore, steps should be taken by the manufacturers to give the correct concentration of fertilizer in the packages and the user must apply it according to standard rate.

Use of fertilizers harms not only plants but also disturbs the ecosystem. The rains carries the excess fertilizer to water body such as pond, lakes, rivers, and others, where the aquatic organisms intakes this fertilizer and experiences prolific growth exhausting most of the oxygen supply of water. This causes imbalances in the ecosystem, as the aquatic plants does not get sufficient oxygen.

The use of fertilizers must be avoided in open land and reduced to minimal in garden and pots according to experts.
