Farming Practices - Impact On Carbon Cycle

Question 1

Carbon sequestration

Answer 1

Natural / artificial process which co2 is removed from atmosphere and stored

Question 2

Positive carbon sequestration

Answer 2

Farmers grow plants = more photosynthesis = more co2 stored in biosphere = less co2 in atmosphere

Farmers will animals meaning more carbon stored in living matter

Question 3

Negatives of carbon sequestration

Answer 3

Crops easily burned.

Animals -enteric fermentation

Question 4

Tillage farming method

Answer 4

Soils natural state is changed and soil microorganisms disturbed

Question 5

Positive tillage farming methods

Answer 5

Soil erosion reduced - maintains long term productivity.

Water conservation.

Retain carbon I soil

Question 6

Negatives of tillage farming method

Answer 6

Artificial fertilisers

Question 7

Controlled burning

Answer 7

Technique used to manage forests , farming restoration .

Helps seeds germinate

Question 8

Positive of controlsd burning

Answer 8

Nutrients for new generation growth

Refreshes habitat zones

Question 9

Negatives of controlled burning

Answer 9

Decrease in carbon stored and increase of co2 directly released to atmosphere

Question 10

Heavy machinery

Answer 10

Use of trackers / ploughing

Question 11

negfauvws heavy machinery

Answer 11

Inverts soil - meaning more microbial activity and more decomposing - more co2 released

Machinery itself releases lots of fossil fuels

Question 12

Agroforestry

Answer 12

Maintenance and planting of trees - increase biodiversity

Question 13

Positives agroforestry

Answer 13

More vegetation / trees more stores
