Using dairy manure and legumes in crop rotations can reduce inorganic N inputs for corn (Zea mays L.), yet these practices also contribute to nitrous oxide (N2O) emissions. In two we investigated how different (i) organic amendments (ii) prior legume crops with broadcast influenced direct N2O emissions from silt-loam soils planted no-till corn. We measured fluxes April December years using clos...

This study aimed to evaluate the relationship of edaphic fauna under a no-tillage system with different levels soybean productivity [High (NTH), Medium (NTM) and Low (NTL)] in west Santa Catarina (Brazil), identifying which chemical physical variables most affect them, best indicators that can be used. Native forest (NF) areas were used as reference. A total 207 samples soil collected by monoli...

A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...

No-till management has been shown to increase soil aggregation, reduce erosion rates, and increase soil organic matter across a range of soil types, cropping systems, and climates. Few agricultural practices provide similar opportunities to deliver positive benefits for farmers, society, and the environment. The potential benefits of no-till are not being fully realized, however, in large part ...

A number of economic and environmental benefits are associated with the use of no-till in production agriculture in the United States. There are lower labor, energy, and machinery costs associated with no-till farming relative to conventional tillage systems and other types of conservation tillage. Reduced erosion and runoff associated with no-till also lead to a number of environmental benefit...
