Some of these benefits led to reductions in the emission of the greenhouse gas (GHG) carbon dioxide (less fuel and machinery used than in conventional tillage systems).

Through reduced tillage in farming — no - till being the prime example — and systems using cover crops and residue, those are major ways agriculture can reduce the emission of greenhouse gases because carbon dioxide is being taken up by the plant materials and stored in the soil.

Forage studies and other research on tillage practices, moisture retention, carbon storage, and other climate parameters remind us that a climate assessment must acknowledge that not only does climate affect rangelands, but broad expanses of rangeland also may affect climate (Retallack 2013).

Minimum tillage with biological nutrient recycling, as opposed to plowing and chemical fertilizers, could sequester 0.4 — 1.2 GtC / year [176] while conserving water in soils, building agricultural resilience to climate change, and increasing productivity especially in smallholder rain - fed agriculture, thereby reducing expansion of agriculture into forested ecosystems [177]--[178].

The determining factor for energy consumption of a specific crop is cropping management, which includes tillage intensity, manuring and weed control.

Wes Jackson, founder and director of the Land Institute in Sauna, Kansas, says that the plow may well be the most significant and far - reaching artifact in human history While we often think of the plow as a tool of peace and prosperity few other instruments compare in their ability to put the long - term survival of life forms at risk The reason is simple: tillage agriculture tears open and makes vulnerable the soil membrane that supports all life.

In the fall of 2012, Rodale Institute in collaboration with USDA - ARS Beltsville Agricultural Research Center and North Carolina State University were awarded a USDA NRCS Conservation Innovation Grant to demonstrate the integration of starter fertilizers (pelleted manure) and their impacts on yield and weed competition in cover crop - based, reduced - tillage organic corn production.

By destroying the natural soil fertility and disturbing the soil through tillage, industrial farming also adds to the deterioration of soil and its carbon emissions.

18 Agriculture is defined as the cultivation of land as in raising crops, husbandry, and tillage farming.

The video also points out that less tillage also decreases C02 emissions from farm machinery since the equipment makes fewer runs over the field.

The study found that even if corn residue (or stover) is harvested responsibly (removing only 30 to 50 percent depending on tillage choice) there was still a loss in soil carbon and the overall savings in greenhouse gas emissions were much smaller than those with switchgrass and miscanthus.

In response, farmers employ different tillage practices.

Encouraging the fungal community and increasing carbon inputs from roots by minimizing tillage and planting perennial crops enhances soil structure and increases carbon storage times.

Tillage affects soil carbon by influencing the rate of increase or decrease in carbon to a new equilibrium level.
