2. Manure
• Manures are organic substances
obtained through the decomposition of
plant wastes (like straw) and animal
wastes (like cow dung). The
decomposition is brought about by the
action of microbes.
• Manures contain nutrients in small
quantities and therefore are needed to
be supplied to crops in large quantities.

3. • Manures are recycled and do not
cause pollution.
• They enrich the soil with nutrients.
• Being rich in organic matter,
manures improve soil texture and
soil aeration. Water holding
capacity in case of sandy soils and
drainage in clay soil is increased.
