system‚ also known as Deep Water Culture‚ is a method of plant propagation where the roots are suspended in nutrient which have rich in oxygenated water. It is essentially a top fed deep water system which pumped from the reservoir to the top of the roots. Thus‚ it helps significantly in enhancing growth in the first few weeks. This technology has advantages when being set up in the process of experiment. The roots get easy access to water from the beginning. It has high yields compared to the amount

trees‚ ensured that salts were dissolved as rainwater slowly filtered down through the soil. Salt was moved downward and remained in the groundwater below the root zone of the plants. The fibrous root structure of those native plants‚ acted as an effective filter with their high water-holding capacity. Some rainwater was held by the roots and some rainwater leached downwards through the soil carrying the dissolved salts. Groundwater transpired back into the air through the leaves of the native plants

it is unwanted. It is funny that even if you take all the measures to avoid weeds from growing it somehow manages to grow and spoil the flower near it. Weeds are very worrying as they tend to be toxic and can be predatory at times. Due to its vast root system it tends to absorb all the water and sunlight and leaves a very less amount of water to the flower/plant growing near it. It is better if we remove the weed when it is very small and still needs to bud as it can quickly grow and disperse. Weeds

Phytoremediation uses one basic concept: the plant takes the pollutant through the roots. The pollutant can be stored in the plant (phytoextraction)‚ volatized by the plant (phytovolatization)‚ metabolized by the plant (phytodegradation)‚ or any combination of the above. Phytoextraction is the uptake and storage of pollutants in the plants stem or leaves. Some plants‚ called hyperaccumulators‚ draw pollutants through the roots. After the pollutants accumulate in the stem and leaves the plants are
