### sch.3-sec.4 Meaning of waterlogged layer A waterlogged layer , for soil in land, is a layer in its profile with any of the following— a dominant soil colour that is gleyed; a dominant soil colour that— is grey; and has at least 10% distinct or prominent mottles of an orange or rusty colour; any other dominant soil colour that has at least 10% distinct or prominent mottles of a gleyed colour; a conspicuous bleach at least 100mm thick not directly overlying bedrock or weathered rock. For this section, a soil’s colour must be worked out by visually comparing it with a standard soil colour chart. In this section— conspicuous bleach means a white or almost white colour— that is the dominant colour of the layer; and that contains 10% or less mottles; and for which its closest match (when dry) is to a colour chip with a value of 7 or 8 and a chroma of 4 or less on a standard soil colour chart’s 5YR, 7.5YR or 10YR chart. gleyed , for a soil colour, means— it is bluish-grey to greenish-grey; and its closest match (when moist) is to the colour chips of a standard soil colour chart of any colour chip— on a gley chart; or with a value of 7 or 8 and a chroma of 3 or less on a standard soil colour chart’s 2.5Y or 5Y chart. grey , for a soil colour, means— it is not gleyed; and its closest match (when moist) is to a colour chip with a value of 4 or more and a chroma of 2 or less on any chart of a standard soil colour chart. mottles means clear patches or streaks of sub-dominant colour (when moist) within a differently coloured soil matrix. orange , for a soil colour, means its closest match (when moist) is to a colour chip with a value 6 or 7 and a chroma of 6 or more on a standard soil colour chart’s 5YR or 7.5YR chart. rusty , for a soil colour, means its closest match (when moist) is to a colour chip with a value of 3 or more and a chroma of 3 or more on a standard soil colour chart’s 2.5YR, 5R, 7.5R or 10R chart. (sch.3-sec.4-ssec.1) A waterlogged layer , for soil in land, is a layer in its profile with any of the following— a dominant soil colour that is gleyed; a dominant soil colour that— is grey; and has at least 10% distinct or prominent mottles of an orange or rusty colour; any other dominant soil colour that has at least 10% distinct or prominent mottles of a gleyed colour; a conspicuous bleach at least 100mm thick not directly overlying bedrock or weathered rock. (sch.3-sec.4-ssec.2) For this section, a soil’s colour must be worked out by visually comparing it with a standard soil colour chart. (sch.3-sec.4-ssec.3) In this section— conspicuous bleach means a white or almost white colour— that is the dominant colour of the layer; and that contains 10% or less mottles; and for which its closest match (when dry) is to a colour chip with a value of 7 or 8 and a chroma of 4 or less on a standard soil colour chart’s 5YR, 7.5YR or 10YR chart. gleyed , for a soil colour, means— it is bluish-grey to greenish-grey; and its closest match (when moist) is to the colour chips of a standard soil colour chart of any colour chip— on a gley chart; or with a value of 7 or 8 and a chroma of 3 or less on a standard soil colour chart’s 2.5Y or 5Y chart. grey , for a soil colour, means— it is not gleyed; and its closest match (when moist) is to a colour chip with a value of 4 or more and a chroma of 2 or less on any chart of a standard soil colour chart. mottles means clear patches or streaks of sub-dominant colour (when moist) within a differently coloured soil matrix. orange , for a soil colour, means its closest match (when moist) is to a colour chip with a value 6 or 7 and a chroma of 6 or more on a standard soil colour chart’s 5YR or 7.5YR chart. rusty , for a soil colour, means its closest match (when moist) is to a colour chip with a value of 3 or more and a chroma of 3 or more on a standard soil colour chart’s 2.5YR, 5R, 7.5R or 10R chart. - (a) a dominant soil colour that is gleyed; - (b) a dominant soil colour that— (i) is grey; and (ii) has at least 10% distinct or prominent mottles of an orange or rusty colour; - (i) is grey; and - (ii) has at least 10% distinct or prominent mottles of an orange or rusty colour; - (c) any other dominant soil colour that has at least 10% distinct or prominent mottles of a gleyed colour; - (d) a conspicuous bleach at least 100mm thick not directly overlying bedrock or weathered rock. - (i) is grey; and - (ii) has at least 10% distinct or prominent mottles of an orange or rusty colour; - (a) that is the dominant colour of the layer; and - (b) that contains 10% or less mottles; and - (c) for which its closest match (when dry) is to a colour chip with a value of 7 or 8 and a chroma of 4 or less on a standard soil colour chart’s 5YR, 7.5YR or 10YR chart. - (a) it is bluish-grey to greenish-grey; and - (b) its closest match (when moist) is to the colour chips of a standard soil colour chart of any colour chip— (i) on a gley chart; or (ii) with a value of 7 or 8 and a chroma of 3 or less on a standard soil colour chart’s 2.5Y or 5Y chart. - (i) on a gley chart; or - (ii) with a value of 7 or 8 and a chroma of 3 or less on a standard soil colour chart’s 2.5Y or 5Y chart. - (i) on a gley chart; or - (ii) with a value of 7 or 8 and a chroma of 3 or less on a standard soil colour chart’s 2.5Y or 5Y chart. - (a) it is not gleyed; and - (b) its closest match (when moist) is to a colour chip with a value of 4 or more and a chroma of 2 or less on any chart of a standard soil colour chart.
