Question

Vermicompost produced by earthworm contains nitrogen(N) and phosporous in this ratio.

• A. $30\%$ N and $2.04\%$P
• B. $20\%$ N and $1.04\%$P
• C. $10\%$N and $3.04\%$P
• D. $60\%$N and $5.04\%$P

Answer 1

Answer: (A)

$30\%$ N and $2.04\%$P

Earthworms are traditionally called as friends of farmers because they increase aeration and make available nitrogen and potassium to plants in easily usable form. Earthworms have been used in vermicomposting. In order to enhance the growth of the plant and fertility of soil must have a particular nitrogen and phosphorous ratio. Over fertilization of nitrogen in the vermicompost can lead to nitrogen burn. Nitrogen burn is the overfertilization of nitrogen leading to scorching of leaves. Thus, 30% nitrogen and 2.04% of phosphorous is the ratio of vermicompost produced by earthworm. Thus, the correct answer is option A.
