Determination of the critical soil mineral nitrogen

A critical soil mineral nitrogen concentration (Nmin) for guiding fertilizer application and maximizing maize grain yield is needed. A threeyear field experiment with three N regimes, unfertilized (N0), optimized N management (Opt.) and conventional N practice (Con.) was performed in maize. The mean soil Nmin in 060 cm soil profile for N0, Opt. and Con. treatments was 2.0, 6.7 and 8.9 mg

Mining valuable minerals from seawater: a critical

1. Introduction Oceans and seas cover nearly threequarters of the earth's surface 1 and contain about 1.3 × 10 18 tonnes of water. 2 They are composed of 96.7% water and 3.3% dissolved salts. 3,4 This concentration of salts works out to be approximately 5 × 10 16 tonnes of salts which constitutes much more than most minerals that are available as landbased reserves and annually mined from
