The highest content of NPK is present in which organic manure?

  • A.Farm yard manure
  • B.Poultry manure
  • C.Town compost
  • D.NADEP compost

Answer: B

Poultry manure has the highest content of nitrogen, phosphorus and potassium among the organic manures listed, which is why it is used as a concentrated manure.

Farm yard manure, town compost and NADEP compost have lower nutrient levels.

Poultry manure is richer than farmyard manure, as the nitrogen and phosphorus in bird droppings are high, and it is used as a concentrated organic manure. Town compost and NADEP compost are lower in nutrients.
