Why no-tillage

TILLING IS COSTLY

 

TILLING IS HARMFUL TO THE SOIL STRUCTURE

Intensive tilling destroys the biological and ecological integrity of soil systems

Real Direct Seeding integrates

Ploughing is harmful

  • the integrity and load-bearing capacity of the soil is good
  • the soil is covered by plants throughout the year
  • the soil retains nutrients, the erosion is insignificant
  • the soil acts as a carbon sink
  • the soil breaks down easily, rich in organic matter
  • activity of micro-organisms increases
  • crop-production capacity of the soil is improved
  • breaks down natural integrity of the soil
  • the soil surface is uncovered in spring and autumn
  • erosion transfers nutrients into bodies of water
  • carbon content of soil is reduced
  • amount of organic matter is reduced, the soil is compacted
  • the activity of micro-organisms is reduced
  • crop-production capacity of the soil is impaired

TILLING RELEASES CARBON DIOXIDE INTO THE ATMOSPHERE

No-tillage and plant cover prevent burning of carbon

Amount of carbon increases

Amount of carbon decreases

  • humus content of the soil increases plant residues on the soil surface protect and nourish

Untilled soil is a carbon sink

  • non-tilled soil and plant residues on the soil surface prevent burning of carbon
  • as the amount of organic matter and carbon increases, the soil structure is improved
  • in ploughed soil 0,77 t/ha/year, which in connection with oxidation emits into the atmosphere 2,85 t/ha carbon dioxide

Tillage releases carbon dioxide

  • tilling makes the soil porous
  • the oxygen in the air reacts with carbon in the soil and forms carbon dioxide
  • as carbon is reduced, the soil structure is impaired

Ploughing and tilling break down the integrity of the soil crumbs, exposing them to erosion. Water drops and melt waters break out nutrients and sediment from the exposed soil.

Real Direct Seeding keeps the soil intact and the crumbs stick together. The soil surface is protected by stubble and straws. They prevent breaking down and leaching of the sediment with the water. The soil under Real Direct Seeding retains 70% more water and nutrients than tilled and ploughed soil.
