Question

Fertigation is
A. the addition of fertilizers directly to stem
B. the controlled addition of fertilizers
C. the addition of fertilizers to irrigation water
D. slow addition of fertilizers to plants

Answer 1

Hint: We know that fertilizers are chemical substances that are added to soil for better production of crops. These substances increase fertility of soil. There are many kinds of fertilizers, such as, phosphorus fertilizer, nitrogen fertilizers, etc.

Complete step by step answer:
Let’s understand the fertigation process in detail. It is the process in which fertilizer is dissolved in water and then distributed along with water by drip irrigation. It is the modern technique to distribute fertilizer by irrigation system. This technique of distribution of fertilizer is better than the traditional method. Using this technique, quantity of both water and nutrients can be managed to obtain maximum crop production.
Therefore, we can say that in the process of fertigation, fertilizers are added to the irrigation water.
Let’s understand drip irrigation in detail. It is a method of supplying water which involves the controlled delivery of water directly to the root of the plants by a network of pipes. The efficiency of drip irrigation is more than the sprinkler system because in drip irrigation there is little loss of water by evaporation and runoff. In this method, water is supplied directly to the plant root zone where water is needed most.

So, the correct answer is Option c.

Note: Always remember that there are three main constituents of fertilizers. They are nitrogen (N), phosphorus (P) and potassium (K). Some examples of fertilizers are urea, potassium chloride, etc. The use of fertilizers has many disadvantages, such as excess nitrogen of fertilizers gets mixed with water and causes harm to aquatic organisms.
