Cambridge University Press & Assessment would like to apologise for errors in the above article. There was an incorrect data value with two occurrences, in which ‘163% (P < 0.01)’ should be replaced with ‘62% (p value = 0.02)’.

The abstract originally contained the following sentence:
‘In treatment fields, 162mm of rainfall per year was saved as soil moisture and on average 13,090 kg per hectare of soil was lost from farm fields without CB, and CB implementation significantly reduced the soil loss by 163% (P < 0.01).’
This should have been:
‘In treatment fields, 162mmof rainfall per year was saved as soil moisture and on average 13,090 kg per hectare of soil was lost from farm fields without CB, and CB implementation significantly reduced the soil loss by 62% (p value = 0.02).’

The original text in the first paragraph under the heading ‘Environmental aspects’ was given as:
‘Data records for 2 years (2016 to 2017) showed that in treatment fields, on average, 162mm of rainfall per year was saved as soil water and soil loss was reduced by 163% (P < 0.01).’
This should have been:
‘Data records for 2 years (2016 to 2017) showed that in treatment fields, on average, 162mm of rainfall per year was saved as soil water and soil loss was reduced by 62% (p value = 0.02).’
