Fertiliser was also applied across treatments to ensure that nutrient supply did not limit crop growth. Initial measurements of topsoil physical, chemical and biological properties were made in October 2017 and a soil health scorecard was produced. ...
This is well below rooting depth, in the vadose zone far below the topsoil but above the water table. And even in this supposedly inert zone, soil microbes were still playing a role in the cycle of life. ...
On the other hand, the trees react quickly as soon as rainfall resumes normal levels in the following spring, thanks to their complex root system that efficiently soaks water from topsoil and taps it from deep reserves. “There is an immediate response,” says lead author Vanda Oliveira, who conducted the study alongside co-authors Alexandra Lauw and Helena Pereira. ...

They conclude that changing from conventional ploughing to reduced or conservation tillage methods changes the distribution of soil organic content in topsoil and has a positive effect on earthworm populations. These could be important ways of sustaining soil conservation and plant production in agro-ecosystems. ...
