Controlled traffic farming: A review of the environmental impacts

European Journal of Agronomy, 2013
Abstract Controlled traffic farming (CTF) is a strategy to minimise soil compaction, which is being implemented worldwide. The aim of this study was to review and analyse the state-of-the-art regarding the environmental impacts of CTF. CTF, when compared with random traffic farming (RTF), was able to reduce environmental issues, such as soil ...

Controlled traffic farming effects on soil emissions of nitrous oxide and methane

Soil and Tillage Research, 2018
Soil compaction affects soil aeration and gas diffusivity, and thus has a major impact on the release of greenhouse gases (GHGs) from fertilised soils. Controlled traffic farming (CTF) systems reduce the area of compacted soil by confining all field traffic to permanent traffic lanes, and a pilot trial at one long-term CTF site provided evidence of ...

Soil compaction and controlled traffic considerations in Australian cotton-farming systems

Crop & Pasture Science, 2016
A literature review was conducted to collate best practice techniques for soil compaction management within cotton-farming systems in Australia. Universally negative effects of traffic-induced soil compaction on the whole-farm system and the wider environment include: (i) increased gap between attainable and potential yields, (ii) increased costs of ...

Tramline establishment in controlled traffic farming based on operational machinery cost

Biosystems Engineering, 2010
This paper presents a targeted approach for the estimation of the operational machinery costs on an annual basis in controlled traffic farming (CTF) systems. The approach combines four sub-models based on existing algorithmic approaches, to evaluate the consequences in terms of machinery performance of different driving directions when establishing ...

Building and Testing Traffic Lanes for Controlled-Traffic Farming

Transactions of the ASAE, 1989
ABSTRACT Atire and wheel load like those on a new wide-span research machine were used in two soil bins to compact and test simulated field traffic lanes. Soil strips with initial heights of 0, 13 and 25 cm were compacted into lanes that were recessed, level and elevated, respectively, relative to adjacent simulated crop zones.

Controlled Traffic Farming

2009
The cycle of traffic-induced soil compaction and tillage is a major inefficiency of current mechanised agriculture, where random field traffic wastes energy, damages soil structure and imposes other negative consequences. Controlled traffic farming (CTF) restricts compaction to precise traffic lanes, where it improves wheel performance, allowing ...

Controlled traffic farming in precision agriculture

2018
In the past few decades, there has been a continuous drive towards the development and adoption of larger, and more powerful, agricultural machinery (Kutzbach, 2000; Jorgensen, 2012). Larger machinery is often related with timeliness, higher work rates and lower labour requirements, which has led to significant improvements both in efficiency and ...

Auto-Steering and Controlled Traffic Farming – Route Planning and Economics

2017
Agriculture nowadays includes automation systems that contribute significantly to many levels of the food production process. Such systems include GPS based systems like auto-steering and Controlled Traffic Farming (CTF). These systems have led to many innovations in agricultural field area coverage design. Integrating these advancements, two different
