In order to prevent or, where that is not practicable, to reduce emissions of nitrogen, phosphorus and microbial pathogens to soil and water from manure landspreading, BAT is to use all the techniques given below.

Technique
a

Assess the manure receiving land to identify risks of run-off, taking into account:

  • soil type, conditions and slope of the field;

  • climatic conditions;

  • field drainage and irrigation;

  • crop rotations;

  • water resources and water protected zones.

b

Keep sufficient distance between manure spreading fields (leaving an untreated strip of land) and:

  1. 1..

    areas where there is a risk of run-off to water such as watercourses, springs, boreholes, etc.;

  2. 2..

    neighbouring properties (including hedges).

c

Avoid manure spreading when the risk of run-off can be significant. In particular, manure is not applied when:

  1. 1..

    the field is flooded, frozen or snow-covered;

  2. 2..

    soil conditions (e.g. water saturation or compaction) in combination with the slope of the field and/or field drainage are such that the risk of run-off or drainage is high;

  3. 3..

    run-off can be anticipated according to expected rainfall events.

dAdapt the manure landspreading rate taking into account the nitrogen and phosphorus content of the manure and taking into account the characteristics of the soil (e.g. nutrient content), the seasonal crop requirements and weather or field conditions that could cause run-off.
eSynchronize manure landspreading with the nutrient demand of crops.
fCheck the spreading fields at regular intervals to identify any sign of run-off and properly respond when necessary.
gEnsure adequate access to the manure store and that loading of manure can be done effectively without spillage.
hCheck that machinery for manure landspreading is in good working order and set at the proper application rate.
