The data presented on this page and in the attached Information Sheets show the Deep Seedbed Conditioner dramatically:
The creation of a deeper, loose, structurally stable root zone soil:
The UNDISTURBED crop root systems in DSC soils INCREASED in mass by > 30 % and depth (> 85 % of this increased root mass occurred between 100 – 300 mm soil depth), and were shown to:
A stand-alone DSC machine requires only ONE rapid, low energy operation prior to seeding.
A DSC machine attached to the front of a seeder requires NO extra operation prior to seeding.
AND, occasional deep ripping and/or gypsum applications are no longer required.
Easily readable details of these findings are presented in Information Sheets attached to the Green Bars below.

This Information Sheet describes the location, soil type, number and type of crops, seedbed type and seasonal conditions (rainfall and irrigation) under which the DSC machine was tested. It also draws attention to the distinction between soil and field productivity increases. Across all soil types, seedbed types, crop types and seasonal conditions, DSC always produced increased yields, even on highly fertile black self-mulching soil.
This Information Sheet outlines the detailed data that explain the extent to which the looseness of DSC root zones is stabilised and root growth is increased and deepened. The consequences of conserving/preserving the extra root growth is shown to be increased soil carbon and nitrogen, plus a large amount of extra income from the sale of carbon credits.
This Information Sheet explains why deep ripping provides only a temporary and unsatisfactory fix for soils with compact subsoils and uses data collected from a DSC treated site with compact subsoil to illustrate how and why it is the best way to rehabilitate compact soils. Compared to a no-tillage treatment the DSC soil
(i) maintained its looseness to 250 mm depth with no discernible consolidation throughout three variable rainfall growing seasons;
(ii) had a water holding capacity that was 35 per cent larger and
(iii) had plant water extraction that was 65 per cent greater.
This Information Sheet explains why gypsum applications are unreliable and basically an ineffective means of rehabilitating sodic soils. Comparatively, sodic soils subjected to DSC practice have their structure stabilised by enlarged and conserved root systems and increased soil biological activity. In turn, the stabilised and porous root zone is rarely saturated, which prevents dispersion occurring and makes these soils more productive.
