COMPARISON OF TINE

AND DISC SEEDER

COMPARISON OF TINE AND DISC SEEDER IMPLEMENTS IN A MINIMUM TILL APPLICATION

Summary

Crop residues, or stubble, can potentially play an important role in contributing to soil
health and nutrient cycling in broadacre cropping. Further positive factors such as
improved rainfall infiltration and soil moisture retention make stubble retention
desirable. The challenge however is that, while the benefits of stubble retention are
widely recognised, growers are faced with significant issues that can arise when
stubble is retained. These issues include problems with weed, pest and disease
control, crop nutrition and the logistics of sowing the following years crop into
potentially high stubble loads.
The so called disc (seeding) and strip (harvesting with a stripper front) system is
gaining popularity in Australian broadacre cropping. Understanding the implications
of changing to such a system is vital to growers in lower rainfall areas in particular. As
a general rule, disc seeders are better able to handle higher stubble loads than tine
and press wheel implements. The proposed demonstration trial will compare the two
types of seeding implement in terms of both productivity (speed and fuel usage) and
agronomic benefit.
