Does inorganic manure decreases the fertility of soil
Answers
Inorganic fertilizer input is one of the main components of AI (Firbank et al., 2008; Tivy, 1990) with a number of potential direct and indirect effects on biodiversity (Robinson and Sutherland, 2002). Although artificial fertilization clearly contributes to the monopolization of primary production by agriculture, it also increases the global productivity of the system, and thus some mixed responses of biodiversity components might be expected. Geiger et al. (2010a) did not demonstrate any significant effect of inorganic fertilizers on the species richness of vascular plants, carabid beetles or birds. However, Guerrero et al. (2011) focused on the FD of birds using the AGRIPOPES data and showed a positive relationship between the diversity of some functional groups, such as diet type and nesting strategy, and the amount of N fertilizers probably related to the increased productivity of agroecosystems.
