An Introduction to Agrowplow

Keith Ryan

Agroplow Wellington Pty Ltd, Wellington

The equipment we design and manufacture is a range of specialised Agrowplows used for both primary and secondary tillage, without soil inversion and minimising moisture loss, whilst allowing deep working with tractor horsepower requirements reduced substantially.

Agrowplow, due to the low angle digging tool and narrow shank, ensures that the previous crops' root systems are fully retained in the soil thus improving structure, adding humus, increasing infiltration and holding moisture whilst allowing greater utilisation of nitrogen created by legume rhizobium bacteria.

Agrowplows can be successfully applied in most situations. It has been used extensively in the farming of cereal, cotton, sugar, vegetables, vineyards and orchards, under both dry land and irrigation farming methods. It is particularly efficient in pasture renovation and control of water run-off, allowing infiltration and storage within the soil system. Wind erosion is reduced and salination problems can be overcome. Hard pans and barriers created by fine particles moving downwards in the coarse soil structures, creating an almost impenetrable layer, can be eliminated.

Agrowplows are made in linkage and trailing models incorporating hydraulic jump, rigid and spring jump shank units. Conversion shanks are also available for fitting to conventional chisel ploughs. Linkage models up to 5 metres and trailing models up to 9 metres with 812mm underframe clearance are available.

When working in pasture it is advisable to use disc coulters in front of each tyne. This will allow the tyne to pass through the matt of root systems thus allowing less clod problems, and also gives you a perfect finish on top. We have had a lot of mixed feelings about the results in pasture renovation. Some say it does not work, others are getting 5-9 fold increase in pasture. If you aerate your pasture around the first break in spring, and get follow-up rain, this is when the best results are achieved, If you work the machine in dry conditions or winter-time, the pasture will decrease for some time, giving farmers the wrong impression of soil aeration.

In a cropping situation, I find the best time to work the Agrowplow is either in pasture fallow or straight after the header has been through. When doing this you will get all of your summer rains into your soil and not running off your paddocks into gullies. The results we have been getting by doing this, either in self-mulching black soils in Queensland or sandy soils in Western Australia, have been from 50-l00% increase on yields.

The deep underground furrows Increase the moisture holding capacity of the soil, absorbing all of the rainfall -whilst ensuring deeper penetration of the plant’s vital life-support systems. With root systems aerated in this way, access Is gained to the limitless quantities of oxygen and nitrogen from the air With minimum soil inversion, seeds can be sown behind the shank into existing root systems. Thus humus provides optimum conditions for germination and rapid, health growth. In cropping work. With a drill attached, the Jump Agrowplow can reduce cereal seed sowing to a one-pass operation.

The above is a utility stump jump model and also available is a ridged model and a hydraulic stump jump model.

MANY AND VARIED NEEDS

All components of Agrowplow products are designed and built with the many and varied needs of the worlds farmers in mind-crop growers and pasture renovators, with either dry-land or irrigation conditions.

The ancient, minimum tillage method of farming gave way to mouldboard and disc plows, with cultivation becoming an exercise of turning over the soil leaving it exposed to water and wind erosion. Whereas Agrowplows, using a low-angle digging profile and assisted by round-nosed shanks and rounded contour shape digging tools, dig much deeper, loosening and aerating the soil and leaving a series of undulating valleys deep in the soil-yet the surface remains virtually undisturbed.
