Table 2 Reference matrix for the percentage reduction of land use type-related value points with respect to (a) the nitrogen retention potential and (b) the yield potential

From: Assessing hydrological and provisioning ecosystem services in a case study in Western Central Brazil

(a)  
Land use-specific value points Nitrogen retention potential
  Value classes High Intermediate Low
Land use types   1 2 3
Coffee 0–10 0 −10 −20
- 11–20 0 −10 −20
Arable land, cotton; 21–30 0 −10 −20
Irrigated land 31–40 0 −5 −10
- 41–50 0 −5 −10
Vegetables; Fruits 51–60 0 −5 −10
Arable land, corn tillage/no tillage 61–70 0 0 −5
Arable land, general, no tillage 71–80 0 0 −5
Arable land, bean 81–90 0 0 −5
Cerrado; Campo; Arable land, sorghum; tillage/ no tillage 91–100 0 0 0
(b)     
Land use-specific value points Yield potential
  Value class High Intermediate Low
Land use types   1 2 3
All arable land use types 0–100 0 −10 −20
  1. The figures in the right column refer to the percentage (%) reduction of initial value points (e.g. -10%).
