Nitrous oxide (N2O) is a greenhouse gas hundreds of times more powerful than carbon dioxide. Agricultural operations account for 60% of N2O emissions in California. For more in-depth coverage about N2O emissions, check out our N2O emissions focus topic page.
What is Compost? What are the Benefits of Compost in Agriculture? Environmental Concerns of Compost Application References Compost is defined as the product resulting from the controlled biological decomposition of organic material1.
The 4Rs of nutrient management. From NutrientStewardship.com. When considering nitrogen fertilizer applications, it is important to consider the Four Rs of Nutrient Management: Right product/source, Right rate, Right time, Right place.
The terrestrial nitrogen cycle. Courtesy of Southwest Hydrology. The nitrogen cycle is a complex web of natural and industrial processes that converts nitrogen into many different chemical forms. Understanding the nitrogen cycle is important when considering how to create a nitrogen budget.
Nitrogen can carryover from one growing season to the next, providing a vital resource for your next crop. This nitrogen can come from the mineralization of soil organic matter or fertilizer, usually in the form of nitrate, that has not been leached below the root zone.
Perhaps one of the most difficult components of a nitrogen budget is determining how much N will become available for crop uptake from organic sources, including crop residues, manure, compost and native soil organic matter.
Nitrate in groundwater has the potential to provide a substantial amount of plant-available nitrogen to crops. Accounting for the nitrate in irrigation water allows for substantial decreases in fertilizer costs.
Organic N mineralization over time Soils have an innate ability to supply crops with plant-available nitrogen throughout a growing season, a process known as nitrogen (N) mineralization.
