Abstract:: ... Core Ideas Soil nitrate was lower due to a cereal rye cover crop during the active growing season. Infiltration was greater for no‐till with rye cover crop than conventional tillage. After 17 years, no‐till with rye had greater soil organic C than conventional tillage in surface layers. Soil organic C did not differ between no‐till with rye and conventional tillage for subsurface layers. No‐till w ...

Abstract:: ... Intensive tillage-based production systems along with residue removal, grazing and/or burning of crop residues/biomass and poor nutrient replenishment through inadequate fertilizer and manure use are the major causes of soil degradation and unsustainable agriculture in hills of North Eastern India. Thus, a 4-year study (2003–07) was conducted during rainy (wet) seasons at Indian Council of Agricul ...

Abstract:: ... Consideration of the environmental effects of the no-tillage practice should be made on the basis of its effects on both carbon and nitrogen cycles. There is a lack of data on the effects of the no-till management in the cool and humid climate and typical soil types of Northern Europe. We measured the fluxes of nitrous oxide (N₂O), carbon dioxide (CO₂) and methane (CH₄) on conventionally ploughed ...
