Repeated monitoring

(according to rain events: +/- 7 to 8 time a year) monitoring supported by digital photography and direct measures:

  • Regular soil surface assessment (crusting/surface structure, roughness) year 1 and 2 with quadrat-points and then, with chain.
  • Crop characteristics: height (m), yield.
  • Mulch and vegetation cover fraction, digital analysis using 1m2 frames at sample locations.
  • CO2 respiration (one time a month from 2005 to 2007).
