TL;DR: It is concluded that agriculture in the next decade will have to sustainably produce more food from less land through more efficient use of natural resources and with minimal impact on the environment in order to meet growing population demands.

TL;DR: In this paper, the potential impact of conservation agriculture on carbon and nitrogen cycling in agriculture has been reviewed by synthesizing the knowledge of carbon cycling and summarizing the influence of tillage, residue management and crop rotation on soil organic carbon stocks.

TL;DR: In this article, a comparative soil quality evaluation is performed in which the performance of the system is determined in relation to alternatives, and the results show that the effect of a reduction in tillage on the variation in total porosity with depth may be related to differences in traffic on different sites, or on soil quality at the time tillage was reduced or stopped.

TL;DR: The long-term effects of different management practices on soil microbial biomass (SMB) (substrate-induced respiration (SIR) and chloroform fumigation incubation (CFI)) and micro-flora physiological and catabolic diversity (BIOLOG TM ecoplate well system) were evaluated by the International Maize and Wheat Improvement Center (CIMMYT) at its semi-arid highland experiment station in Mexico.

TL;DR: In this paper, the authors established a minimum soil quality dataset for a long-term tillage, residue management and rotation trial for wheat (Triticum aestivum L.) and maize (Zea mays L.) production systems.
