Nitrate (NO3-) is the highly mobile form of inorganic nitrogen in both the soil and the plant. Over 98 % of all nitrogen (N) present in the soil is in an organic form, which is mineralised by microbes into inorganic forms (2 % of all N) such as nitrate and ammonia. The positive charged ammonium ion (NH4+) is immobile in soil, does not leach, and is an intermediary in the conversion of organic-N to nitrate (NO3-). As proteins make up much of the content of cells, nitrogen is needed in greater quantity that any other mineral nutrient. Nitrogen is highly mobile within the growing plant allowing it to re-mobilise and move to tissues that can use it more effectively.
Figure 2: Nitrogen deficiency symptoms in wheat plants (right) (Snowball and Robson, 1988).
Stable Organic Nitrogen (SON) is released slowly throughout the season, and is by far the largest nitrogen source in the soil.
Residue Organic Nitrogen (RON) is mineralised rapidly into NH4+ and NO3-, and is highest following legume crops.
Fertiliser Nitrogen is applied to a crop by growers where the above sources cannot meet the needs of the crop.


Due to the number of different nitrogen sources accessible to the crop, it is best to use models to gauge nitrogen status in the soil. Models that use this information are SYN (Select Your Nitrogen) from the Department of Agriculture and Food, Western Australia, and NuLogic from the commercial fertiliser company CSBP. A simple method to determine whether the correct nitrogen regime was used is to measure grain protein following harvest.
In the past, Western Australian growers have had little reason to test for NO3- and NH4+ in the soil, as little mineral nitrogen is present in the soil over summer. Once organic-N is converted to nitrate it is prone to leaching, particularly in sandy textured soils in high rainfall zones where soil compaction problems slow root growth.
Grain yield improvements are mainly caused by increased tiller numbers and grains per ear, both of which are determined early in the life of a wheat plant.
Later nitrogen applications can also have yield benefits through increased tiller survival, leaf duration and photosynthetic area.

Community Food and Health (Scotland)'s (CFHS) new learning and development programme builds on the success of their previous programmes and includes details of activities being held up to the end of March 2012.
Please note: applications are requested from those who work in either community food or community health organisations only.
Participants will look at the policies and principles of community engagement and will be provided with tools and methods to plan and assess their engagement work.
Mineralisation occurs throughout the growing season providing a steady, continuous supply of nitrogen to the crop. Nitrogen plays an essential role in the production of chlorophyll, and any deficiency is displayed as yellowing leaves and reduced tillering in cereal crops (figure 2).


The optimum protein percentage in wheat grain varies between cultivars, however it is a useful tool for auditing nitrogen budgets.
However, in some years summer rain results in mineral-N release from organic matter and soil testing helps in determining the worth of this available nitrogen.
This places importance on a sufficient supply of nitrogen during crop emergence and establishment.
Delaying application however, reduces the chance that economic response to nitrogen will be achieved.
Years ago, who would have thought yogurt in a tube would be such a hit?Consumers like products that can last a longer period of time. This mobility provides a nitrogen source that moves readily towards plant roots, but can also be leached out of reach of the plant root system (figure 1). Increasing N rates to achieve protein levels above these thresholds results in lower economic responses, as protein payments and yield do not offset the extra cost of nitrogen. This can be viewed as a pre-emergent application and can be a significant N source in some years; however it is also prone to leaching if heavy rainfall occurs before crop establishment. Due to potential leaching, nitrogen use efficiency on sandy soils can be improved by delaying fertiliser application until the crops roots system is adequately developed. An advantage of late applications (1st node visible) is that growers have a better idea of yield potential before applying the nitrogen.
Conversely, if crops consistently achieve protein levels below these levels, they are forgoing optimum yield potential. Consumers will be happy to know that eating a healthy product didn’t cost much more than a non-healthy product.If the cost of the product is higher than a less-healthy product – use that as an advantage as well.
