Black Cotton Soils (Vertisols) and the Vetiver System

What follows is a reprint of a note by the late John Greenfield on conservation practices for black cotton soils (vertisols) – It should be an interest too many of you.   I was faced with the problems of managing black cotton soils in the early 50s in Australia while working with the Soil Conservation Service. Overnight, a heavy storm had wiped out a large area of a farmers wheat crop and fence line leaving gullies several meters deep.… Read the rest “Black Cotton Soils (Vertisols) and the Vetiver System”

The Broken Hydrological (Water) Cycle — and Feedback from Vetiver users (NL 2024-08)

The Broken Hydrological (Water) Cycle. Summer is always a rather slow time for exchanging vetiver information –  a time to relax and reflect.  I have been re-reading Charles Massy’s book “Call of the Reed Warbler” (available from e.Books.com). It makes an interesting read (focusing primarily on his own country, Australia) about landscapes that were once in balance with nature, but, since colonization and the introduction of European agricultural methods, have been changed and destroyed, particularly the soils and related water balances.… Read the rest “The Broken Hydrological (Water) Cycle — and Feedback from Vetiver users (NL 2024-08)”

Vetiver Roots as a temporary carbon sink, China Vetiver Network publications, Vetiver and Women, & Vetiver and Regenerative Ag – a bi-national program (NL-2024-07)

Vetiver Roots as a temporary carbon sink Source: Wilson, B., Daniel, H., and Baldock, J.A. 2022. Functional Links between Biomass Production and Decomposition of Vetiver (Chrysopogon zizanioides) Grass in Three Australian Soils. Plants 2022, 11(6), 778; https://doi.org/10.3390/plants11060778 In the broader discussion of the Vetiver System’s relevance in managing the impacts of climate change, this author’s view is that the focus should be on VGT applications for climate change adaptation, with greatest urgency being to support rural communities and smallholder and rainfed farmers in the Global South,  followed by protecting vulnerable lands and making critical infrastructure climate resilient. … Read the rest “Vetiver Roots as a temporary carbon sink, China Vetiver Network publications, Vetiver and Women, & Vetiver and Regenerative Ag – a bi-national program (NL-2024-07)”
