DSC Machine

Deep Seedbed Conditioner (DSC)

Deep Seedbed Conditioner (DSC)

The patented DEEP  SEEDBED  CONDITIONER  is a world-first breakthrough in farming technology.  It  SUBSTANTIALLY  INCREASES  soil and water productivity  WITHOUT  the need to change no-tillage or one-pass seeding, controlled traffic and stubble retention practices.

Its development was based on the truism:                                                                                                                         Once the physical condition of plant root zones is optimised, improved root growth, soil biology,                                                     fertility, water use efficiency and crop productivity will follow.

Deep Blade Loosener
A one and two-halves bed machine made for small irrigated fields in Pakistan. DSC machines can be up to 24m wide, or wider, for towed operation on large dryland cropping fields.

                             ______________________________________________________________________________                                              Farmers have  NEVER  BEFORE  been offered a machine that nurtures and  protects crop roots                                                 and soil biology whilst creating a deep seedbed that sustainably increases                                                                                                       crop production and benefits the  environment.

               ALSO, farmers have  NEVER  BEFORE  been offered a machine that has been specially designed                                  and thoroughly evaluated for its  ABILITY  to :                                                                                                                                                                               (i)   IMPROVE  soil, water & crop productivity;                                                                                                                                    (ii)  MINIMISE  DRAFT  (even when a seeder is attached) ;  and                                                                                                (iii)  be EASILY OPERATED.

DSC  has  NEVER  failed, and  will  never fail, to increase productivity and profitability.

  NOTE :                                                                                                                                                                        Deep seedbed conditioning  DOES NOT  compete with deep ripping or chisel ploughing – it complements           them.  DSC preserves and improves the loose soil they create and  INCREASES  the  benefits.                            

        WHY ?                                                                                                                                                                                                                  –   The  DSC  machine is  NOT  a primary tillage implement.  It has been designed to operate in soil that               has only  PARTIALLY  re-consolidated after having been  FIRST   ripped, or chisel ploughed.         

        HOW ?                                                                                                                                                                                                                  –    The  DSC  machine loosens soil uniformly  to a depth of 300 mm  (in which > 80  % of crop roots grow) over  100  %  of the sown area  WITHOUT  DAMAGING  EXISTING  ROOT  STRUCTURES.   This stimulates  increased root growth and soil biological activity.  Its continued use preserves and increases both, and the increased root mass acts as a reinforcing mesh that stabilises the looseness and minimises soil re-consolidation.                                                                                                                                                                                             ________________________________________________________________________________                       

Data on the magnitude and range of soil, water,  production and operational benefits that derive from the  DSC  machine’s ability to increase and preserve crop roots are given in the other Technology pages.

                         _________________________________________________________________________________                         

The Deep Seedbed Conditioner machine has been developed for  BOTH  broadacre  dryland  and  bed-and-furrow  irrigation  or waterlog-preventative  cropping  and the benefits of its use are produced at all operational scales.

For  ALL  crops, the DSC machine:                                                                                                                                          creates and preserves a deep, loose seedbed of ~ 300 mm depth  over  100 % of the sown area  by                  SLICING  through soil and plant roots at ~ 300 mm depth;                                                                                          with specially designed wings that gently  lift, open and drop soil and intact root structures  and                      their associated soil organisms;                                                                                                                                      with minimal draft force and no smeared soil beneath its wings; and so                                                                  stimulates deeper and enlarged root growth;                                                                                                                    WITHOUT  INVERTING  or  HORIZONTALLY  DISPLACING  ANY  SOIL  or  ROOTS .                                                                                                                                                                                                                                                                                            For BED-and-FURROW   cropping, the DSC  machine is fitted with specially designed furrowers that have:                         easily replaced side plates of varied lengths that:                                                                                                       ensure furrow bases match tyre widths, and so prevent the treads and walls of tyres compacting                           bed shoulders;                                                                                                                                                                 efficiently divide and gently lift and separate the spoil of furrow excavation                                                            with minimal draft force; and                                                                                                                          MINIMAL  SOIL  INVERSION  and  EXPOSURE  of  ROOTS  and  SOIL  BIOLOGY.                                                                                    ____________________________________________________________________________

The enlarged, retained root structures and associated soil organisms in DSC seedbeds reinforce the loose tilth and minimise or prevent  soil consolidation, to the extent that 

             –  > 70  %  of the  EXTRA  porosity   created by DSC  lasts  BEYOND  the next seeding season.                                             ______________________________________________________________________________                     

Note: These attributes deliberately avoid the cultivation-caused destruction of roots and the inversion, exposure and breakdown of organic matter and death of soil organisms – the consequences of which impoverish soils and make them difficult to manage and less fertile.                                                                   (See Info Sheet No. 1, below.)                                                                                                                                                                  _____________________________________________________________________________

The DSC machine can be used for:                                                                                                                                        dryland farming,                                                                                                                                                                                                 waterlog-preventative farming and                                                                                                                                bed-and-furrow irrigation farming.                                                                                                                                                     (See Info. Sheet No. 3, below.)                                                                                                                                                                                                  _____________________________________________________________________________             

The DSC can be manufactured for towed operation, either:                                                                                                 attached to the front of seeders for a one-pass seedbed-renovation-and-seeding operation,                           or as a                                                                                                                                                                                                                       stand-alone, separate operation machine.                                                                                                                           And, it can be manufactured as a                                                                                                                                             3-point linkage machine for separate or tandem operation.                                                                                                                              _____________________________________________________________________________

To maximise operational efficiency and reduce the number of passes, the Deep Seedbed Conditioner can be manufactured in widths from 8m to 24m, or wider if desired, with standard shank spacings of 800 mm.                                      ______________________________________________________________________________

The DSC machine is narrow.  The wheel bases (front-to-back) are:                                                                                            DRYLAND  DSC :                  transport mode – 2,500 mm;    operational mode – 2,900 mm;                                               BED & FURROW DSC :        transport mode – 3,000 mm;    operational mode – 3,400 mm.

The DRYLAND DSC  machine  has three bars, with wheels and disc coulters mounted on the front bar, shanks with wings on the second bar, and wheels and seeder tow-bars on the rear bar.

The BED & FURROW DSC  machine  has four bars, with wheels and disc coulters mounted on the front bar, shanks with wings on the second bar, furrowers on the third bar, and adjustable-angle crumble rollers, wheels and seeder tow-bars on the rear bar.                                                                                                                                                                ______________________________________________________________________________

The  design and operation of the DSC machine ensures its  DRAFT  and  the  DRAFT  of  SEPARATE  or TANDEM  SEEDERS  will  ALWAYS  be VERY  SMALL,  because: 

                i )    The soil and roots in front of the shanks are  CUT  and  LOOSENED   by 50 mm amplitude wavy coulters, and the soil and roots between the 800 mm-spaced shanks are  SLICED   by horizontal blades spanning 750 mm mounted at the base of the shanks.  These lift, open and drop soil and undisturbed root structures : 

          AND 

                ii )    Both machines will  ALWAYS  operate in root-reinforced , LOOSE  tilth from the previous  DSC  crop.
