    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Abstract Seasonal controlled traffic farming (SCTF), i.e. CTF without using the permanent traffic lanes for harvesting and primary soil tillage, leads to improved soil structure, higher crop yields, significant reduction of the emission of nitrous oxide and increased uptake of methane. Improved timeliness of operations, easier mechanical weed control and favourable returns on investments are considered practical advantages of SCTF. Further improvements, including reduced tillage, seem possible by avoiding overcompaction of the soil in the cropping beds during harvesting. The objective of the research was to find out what ground pressures can be applied without compromising soil structure and subsequent growth of a green manure crop, i.e. without tilling the topsoil after compression. No driving over the beds (ground pressure = 0) and simulation of harvesting with equipment requiring tyre inflation pressures of respectively 40, 60 and 80 kPa were investigated. Under dry or moist (field capacity) soil conditions support of harvesting machinery on the planting bed with tyres inflated to 0.4 bar did not lead to severe compaction and subsequent yield reductions.
