Answer 1

The correct option is B Vermicompost, poultry wastes, green manure

$\bullet$ Organic manures are of plant or animal origin. They are not synthetic chemicals.
$\bullet$ Excessive use of chemical fertilizers leads to problems such as saline soil and barren lands. It also causes pollution of underground water. Hence the use of biofertilizers is recommended as it increases the fertility of soil naturally.
$\bullet$ Cow dung, vermicompost, bone meal, goat droppings, poultry wastes, green manure are few examples of organic manures.
$\bullet$ NPK fertilizers, phosphate fertilizers, urea are few examples of chemical fertilizers.
