Foliar-applied Nitrogen Fertilizers in Spring Wheat Production

C admium (Cd) is a nonessential heavy metal that can cause kidney problems. Diet is the main source of Cd for nonsmokers, with cereal products, including pasta, accounting for up to 20% of the daily intake of Cd. The current official standard for maximum level of Cd in durum wheat grain as stated by the Codex Alimentarius Commission is 0.2 ppm. The European Union has adopted this level as the m...

Cyanobacterial N2 fixation in presence of nitrogen fertilizers.

Anabaena oryzae ARM 570 was examined for its growth (chlorophyll and protein), heterocyst frequency, nitrogenase (acetylene reduction) activity, ammonia excretion, and glutamine synthetase and nitrate reductase in response to two levels of urea-N vis-à-vis N2-N. Growth of cyanobacterium increased with duration of incubation. Reduction in heterocyst frequency (40%) was observed at 30 ppm of urea...

New Development In Slow-Release Fertilizers

There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...
