Nutrients and crop nutrition

The use of nutrients (fertilisers) is a key component in agricultural production systems, especially the use of nitrogen and phosphorus, but also potassium and micro-nutrients. Their use has impacts not only in terms of the consumption of non-renewable resources, but those which are not taken up by crops can be lost to the wider environment as pollutants, e.g. nitrate and phosphate in surface and groundwater (contributing to eutrophication) or the loss of ammonia and nitrous to the atmosphere (contributing to acid rain and climate change). Consequently, it is important that nutrients are used efficiently – providing efficient nutrition to the crop while minimising losses to the environment and subsequent impacts. AERU have undertaken numerous projects which have included assessing nutrient use and minimising potential impacts.
