ANNEX III U.K.

BIOPHYSICAL CRITERIA FOR THE DELIMITATION OF AREAS FACING NATURAL CONSTRAINTS

a [F1 Member States][F1 The relevant authority] need only check fulfilment of this criterion against those of the thresholds that are relevant to the specific situation of an area
CRITERION	DEFINITION	THRESHOLD
CLIMATE
Low Temperaturea	Length of growing period (number of days) defined by number of days with daily average temperature > 5 °C (LGPt5) or	≤ 180 days
	Thermal-time sum (degree-days) for Growing Period defined by accumulated daily average temperature > 5 °C	≤ 1 500 degree-days
Dryness	Ratio of the annual precipitation (P) to the annual potential evapotranspiration (PET)	P/PET ≤ 0.5
CLIMATE AND SOIL
Excess Soil Moisture	Number of days at or above field capacity	≥ 230 days
SOIL
Limited Soil Drainagea	Areas which are water logged for significant duration of the year	Wet within 80 cm from the surface for over 6 months, or wet within 40 cm for over 11 months or Poorly or very poorly drained soil or Gleyic colour pattern within 40 cm from the surface
Unfavourable Texture and Stoninessa	Relative abundance of clay, silt, sand, organic matter (weight %) and coarse material (volumetric %) fractions	≥ 15 % of topsoil volume is coarse material, including rock outcrop, boulder or
		texture class in half or more (cumulatively) of the 100 cm soil surface is sand, loamy sand defined as: Silt % + (2 × clay %) ≤ 30 % or
		[X1 Topsoil texture class is heavy clay (≥ 60 % clay) or]
		Organic soil (organic matter ≥ 30 %) of at least 40 cm or
		Topsoil contains 30 % or more clay, and there are vertic properties within 100 cm of the soil surface
Shallow Rooting Depth	Depth (cm) from soil surface to coherent hard rock or hard pan	≤ 30 cm
Poor Chemical Propertiesa	Presence of salts, exchangeable sodium, excessive acidity	Salinity: ≥ 4 deci-Siemens per meter (dS/m) in topsoil or
		Sodicity: ≥ 6 Exchangeable Sodium Percentage (ESP) in half or more (cumulatively) of the 100 cm soil surface layer or
		Soil Acidity: pH ≤ 5 (in water) in topsoil
TERRAIN
Steep Slope	Change of elevation with respect to planimetric distance (%)	≥ 15 %
