Generally, the crop requires modest application of nitrogen fertilizer, as it is not a heavy feeder. Typical nitrogen (N) content of senescent material in the fall is 0.5% N. Fertilizer nitrogen applications of about 5 kg N/hectare (ha) applied for each tonne of biomass removed is a general guideline.
When discussing the application of nitrogen in agriculture, it is essential to consider the sources of nitrogen used. Synthetic nitrogen fertilizers, such as ammonium nitrate and urea , are commonly applied to crops to replenish soil nitrogen levels and enhance crop productivity [ 3 ] These fertilizers provide readily available nitrogen for ...
Through the increasing use of nitrogen fertilizer, which was used at a rate of about 110 million tons (of N) per year in 2012, [132] [133] adding to the already existing amount of reactive nitrogen, nitrous oxide (N 2 O) has become the third most important greenhouse gas after carbon dioxide and methane.
Nitrogen is the most critical element obtained by plants from the soil, to the exception of moist tropical forests where phosphorus is the limiting soil nutrient, [36] and nitrogen deficiency often limits plant growth. [37] Plants can use nitrogen as either the ammonium cation (NH 4 +) or the anion nitrate (NO 3 −).
The County Road Association of Michigan recently released its 2024 list of the state's best best fall color drives with information from Michigan's 83 county road agencies, according to the CRA ...
Now that fall has arrived, daylight saving time's end is around the corner. Here's what to know as clocks falls back in early November.
Basso et al. 2012 demonstrated that variable-rate application of fertilizer can reduce nitrogen application and leaching without affecting yield and net return. [ 99 ] However, precision agriculture could also accelerate farms' depletion of natural resources because of a rebound effect ; increasing input efficiency does not necessarily lead to ...
