Trickle Irrigation System
Trickle irrigation, also known as drip irrigation, is a type of micro-irrigation system where water is applied directly to the plant roots, drop by drop, through a network of pipes and emitters. This system is highly efficient and effective in conserving water and nutrients, as it delivers water and fertilizers directly to the plant roots, reducing evaporation and runoff.
Correct Statement
The statement that is not correct in a trickle irrigation system is option 'C': the evapotranspiration is practically eliminated. Evapotranspiration is the process by which water is lost from the soil through evaporation and plant transpiration. In a trickle irrigation system, the water application is localized, and the soil around the emitter is kept moist, reducing evaporation. However, plant transpiration still occurs, as plants need water for their growth and survival. Therefore, evapotranspiration cannot be completely eliminated in a trickle irrigation system.
Other Statements
The other statements given in the question are correct:
- Deep percolation and runoff are practically eliminated: In a trickle irrigation system, water is applied slowly and in small quantities, reducing the chances of deep percolation and runoff. The water penetrates the soil gradually, allowing it to be absorbed by the plant roots without wasting water or causing soil erosion.
- The water application efficiency is very high: Trickle irrigation is highly efficient in water use, as it minimizes losses due to evaporation, runoff, and deep percolation. The water is applied directly to the plant roots, reducing wastage and increasing the efficiency of the system. This results in higher crop yields and reduced water consumption.
- The fertilizer can be applied economically along with the irrigation water: Trickle irrigation provides an efficient way to apply fertilizers along with the irrigation water. The fertilizers can be injected into the irrigation system, and delivered directly to the plant roots, reducing the risk of leaching and runoff. This results in better nutrient uptake by the plants and improved crop yields.
