Question

can anybody give me a infomative speech on water conservation and drip irrigation n please give agood slogan on save water

Answer 1

Good morning to the excellencies, respected teachers and my dear colleagues. I would like to speech on a very important topic “save water” today at this special occasion. As well all know that how the water is important for the continuation of life on the earth. It is the most basic need of everyone (human being, animal, plant and other microorganisms). Water is the unique source of life, without water we cannot imagine the life here. Life on other planets is not possible just because of the absence of water. It is considered as the most important among other known celestial bodies. Almost three-fourth area of the earth is covered by the water and it constitutes around 60-70 % of the living world. It seems that water is endless renewable source on the earth because it is regenerated and redistributed all over the earth through evaporation and rain. Actually, there is only 1% of the water on the earth which is usable to us. And other water bodies have unusable water to us such as 97% salty sea water, 2% water in the form of glaciers and polar ice caps. Only 1% water is here for us over which a huge population all over the world is depended for the survival. Death is more possible in the lack of water than the lack of food. It again arises a question in our mind that why we are so late in realizing the need of water saving and conservation. Since the life of each and every living things on the earth depends on water, then scenario will get worse if useful water become dirty or started reducing. A water looking fresh and drinkable from outside can be mixed with the harmful and toxic elements through various sources like industries, factories, sewer, etc and cause illness and death if ingested by animals, plants or human beings. Drip irrigation is a type of micro-irrigation that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.The advantages of drip irrigation are:Fertilizer and nutrient loss is minimized due to localized application and reduced leaching.Water application efficiency is high if managed correctly.Field levelling is not necessary.Fields with irregular shapes are easily accommodated.Recycled non-potable water can be safely used.Moisture within the root zone can be maintained at field capacity.Soil type plays less important role in frequency of irrigation.Soil erosion is lessened.Weed growth is lessened.Water distribution is highly uniform, controlled by output of each nozzle.Labour cost is less than other irrigation methods.Variation in supply can be regulated by regulating the valves and drippers. Fertigation can easily be included with minimal waste of fertilizers.Foliage remains dry, reducing the risk of disease.Usually operated at lower pressure than other types of pressurised irrigation, reducing energy costs.
