The rising interest in no - tillage production practices among organic farmers has recently created considerable advancement in the development of a cover crop - based, reduced
tillage organic corn and soybean production.

Organic Cotton Marketing Cooperative (TOCMC), which grows the majority of the
organic cotton in the U.S., its growers do not use any inputs for weed control, preferring to use mechanical
tillage and hand weeding.

It is considered as a holistic and dynamic approach of incorporating
organic and permaculture farming practices including crop rotation, conservation
tillage, composting, cover crops, pasture cropping, and mobile animal shelters to increases the farmer's income and food production.
Soil building practices such as crop rotations, inter-cropping, symbiotic associations, cover crops,
organic fertilizers and minimum
tillage are central to
organic practices.
This was most probably due to inclusion of a green manure legume crop in the third year of rotation and fewer
tillage operations on the
organic field.
Sustainable agricultural strategies comprising recycling of
organic matter, tightening internal nutrient cycles, and low - or no -
tillage practices may rebuild
organic matter levels and reduce losses from the system.
For example, the
organic matter can be balanced by reduced
tillage practices; by double cropping, where two crop varieties are planted in succession in the same growing season; and by the use of cover crops that replenish the soil.
No - till and, to a lesser degree, conservation
tillage maintains or improves soil quality by preserving soil structure and moisture, increasing soil
organic matter, and providing habitat for soil microbes.
For example, large - scale
organic farming relies heavily on
tillage.
This method — called cover crop - based
organic rotational no - till — allows farmers to skip spring
tillage and weeding.
We identified as most promising measures: the promotion of
organic inputs on arable land instead of grassland, the introduction of perennials (grasses, trees) on arable set - aside land for conservation or biofuel purposes, to promote
organic farming, to raise the water table in farmed peatland, and — with restrictions — zero
tillage or conservation
tillage.
Promising soil management techniques include controlled grazing; mulching with
organic matter; applying manure and biosolids; use of cover crops in the rotation cycle; agroforestry; contour farming; hedgerows; terracing; plastic mulch for erosion control; no - till or conservation
tillage; retention of crop residue; appropriate use of water and irrigation; and integrated nutrient management, including the judicious use of chemical fertilizers.
Furthermore, the team found that land that had been cultivated using conservation
tillage since the 1980s had been able to recover more than a fourth of the soil
organic carbon it had lost.
