The U.S. Environmental Protection Agency (EPA) has approved the use of Instinct II nitrogen stabilizer in wheat. Instinct II keeps more nitrogen available in the root zone for enhanced wheat health and optimized yield and profit potential.
Canpotex Ltd, owned by a trio of North American potash producers, is seeking an 8 percent, or $25 per tonne price increase in its 2015 potash supply contract with China's Sinofert Holdings Ltd, Mosaic Co Chief Executive Jim Prokopanko said on Wednesday.
Right rate is especially critical for the full benefit of a fertilizer application. Rate is a threshold requirement, where if the threshold rate is not reached, other 4R factors of source, time and place will not be able to compensate.
Leakages of nutrients necessary for food production – especially nitrogen and phosphorus – cause severe eutrophication to the Earth's aquatic ecosystems and promote climate change. However, this threat also hides an opportunity.
When exposed to nitrogen fertilizer over a period of years, nitrogen-fixing bacteria called rhizobia evolve to become less beneficial to legumes - the plants they normally serve, researchers report in a new study.

Properly timed spring nitrogen applications are essential to the growth and development of wheat. Assessing nitrogen needs now will optimize yield later and is especially important for organic grain growers.
