Large-scale field evaluation of driving performance and ergonomic effects of satellite-based guidance systems

Autor: Oliver Hensel, Zdenek Kviz, Monika Sauter, Martin Holpp, Thomas Anken, Milan Kroulík

Publikováno v: Biosystems Engineering. 116:190-197

Positive driving performance and ergonomic effects are ascribed to satellite-based automatic guidance systems. Although the literature had provided some information on working-width utilisation, turning-time requirement and steering accuracy, the rel

Spatial Variability and Pattern of Selected Properties of Agricultural Soils in the Czech Republic Measured by Indirect Proximal and Remote Sensing

Autor: Milan Kroulík, M. Zlinsky, J. Kumhálová, V. Prosek, Zdenek Kviz, M. Mimra

Publikováno v: Proximal Soil Sensing ISBN: 9789048188581

Spatial and temporal variabilities of soil properties were monitored within a 12-ha field over several consecutive years. Particle-size distribution, total carbon content (Ct), and pH were monitored. Soil samples were taken from points on a regular s

Influence of Overall Straw Management on Next Crop Germination, Growth and Final Yield when Using Conservation Tillage Technologies

Autor: Zdenek Kviz, František Kumhála, Pavel Prochazka

Publikováno v: 2008 Providence, Rhode Island, June 29 - July 2, 2008.

For the purpose of simulation of straw and chaff distribution quality across working width of a combine harvester after its passage, different straw management variants with even and uneven plant remains placement were established. It has to be state

Capacitance Sensor for Forage Mass Determination

Autor: Zdenek Kviz, V. Prošek, František Kumhála

Publikováno v: Scopus-Elsevier

Non-contacting methods for material properties determination and crop yield determination are the best solution especially for rough conditions in agriculture, however, it requires reliable and durable sensors as a source of primary data. The capacit

Reliability and Accuracy of Astronomical Observations by Amateurs

Autor: Zdenek Kviz

Publikováno v: International Astronomical Union Colloquium. 98:134-137

Who is an amateur-astronomer? We would certainly find several definitions if we tried to get answers from the audience. I am not trying to force anyone to accept my definition, in fact I do not know if I really have one. Someone who likes to read boo

Machinery guidance systems analysis concerning pass-to-pass accuracy as a tool for efficient plant production in fields and for soil damage reduction

Autor: J. Chyba, Zdenek Kviz, Milan Kroulík

Publikováno v: ResearcherID
Scopus-Elsevier

Machines without satellite navigation in fields have a tendency to pass-to-pass errors, especially unwanted overlaps, resulting in waste of fuel and pesticides, longer working times and also environmental damage. This paper evaluates the accuracy of

The measurement of plant residues distribution quality after harvest by conventional and axial combine harvesters

Autor: František Kumhála, J. Mašek, Zdenek Kviz, P. Procházka

Publikováno v: Scopus-Elsevier

This paper concerns the evaluation of the husk and straw distribution quality measurement on different commonly used combine harvesters. The plant residues can significantly influence the next plant germination and growth, espe cially when they are u
