Question

__________ will increase soil nitrates, while ___________ will decrease soil nitrates.

Answer 1

Animal manure will increase soil nitrates, while fast growing crops will decrease soil nitrates.

What will decrease soil nitrates?

Denitrification and dissimilatory nitrate reduction to ammonium (DNRA), two significant nitrate-reducing mechanisms in soil, are in charge of nitrate (NO 3 ) loss and the creation of nitrous oxide, a powerful greenhouse gas (N2O).

What increases nitrogen in soil?

• Naturally occurring sources of nitrogen addition to soil include air deposition from rainfall and N fixation by soil bacteria and legumes.
• Usually, fertilizers, manure, or other organic sources provide the crop with extra N.

What causes low nitrogen in soil?

• N deficiency is associated with the type of soil and is typical in sandy, well-drained soils with rapid nitrogen loss.
• Overwatering owing to excessive irrigation and heavy rains results in nitrogen shortage.
• The ability of plant roots to absorb water-soluble nutrients is hampered by a lack of soil moisture.
