1. N rates shown above refer to application rates of available fertilizer. Chemical fertilizer rates should be calculated by deducting the available N contained in organic fertilizer applications from the rates shown in the above table.
2. See accordian below for information on Soil N Index.
3. The Phosphorus fertilization rates for soils which have more than 20% organic matter shall not exceed the amounts permitted for Index 3 soils.
4. P rates shown above refer to recommended application rates of available fertilizer.
5. Chemical fertilizer rates should be calculated by deducting the P contained in organic fertilizer applications from the rates shown in the above table.

1. Assuming no organic manures are supplied
2. Assuming Nitrogen Index = 1

There is, as yet, no satisfactory Irish laboratory test for N in soils at farm level.

1. Nitrogen is not required for field peas or beans.
2. Research by Teagasc has shown no benefit of nitrogen application at sowing.
3. Nutrient N advice for grassland systems (grazing and conservation) depends mainly on land use and farming system, and particularly on the stocking rate.
4. For crops requiring cultivation, the available soil N can be deduced from the previous cropping and manurial history, and the type of soil. Thus, N fertilizer advice is determined by the soil N supply status. This depends in turn on the previous cropping history.

The supply status is categorised into an Index system for grass establishment and tillage crops.

N Index for tillage crops that follow short leys or tillage

N Index for pasture establishment or tillage crops that follow long leys or permanent pasture

1. The optimum soil pH for Beans is 6.8.
2. Where lime
   recommendations advise are in excess of 7.5 t/ha, it is good practice to apply the lime over a 3-year period. This helps avoid too much lime applied at any one time which can lead to boron and manganese
   deficiencies.

1. Field Peas and Beans may respond to the application of Magnesium at soil Index 1
2. Goulding Soil Nutrition offer Wolf Trax Magnesium DDP as an option to be coated onto fertilisers, Kieserite, a Mg + S fertiliser and Polysuphate (K, Mg, S, Ca) as options to treat Mg deficiencies. Including Magnesium in your fertilisers allows for earlier intervention (seedbed) when magnesium deficiency is a known issue.
3. Magnesium sulphate (epsom salts) is widely used to correct Mg deficiency and
   comes with the benefit of additional small quantity of S.

1. Field Peas and Beans should not be drilled in soils that have been treated with Boron
