This chapter reviews proximal soil sensing (PSS). Our intent is for it to be a source of up-to-
date information on PSS, the technologies that are currently available and their use for …

Spatially variable soil compaction often causes inconsistent growing conditions in many
fields. Various soil compaction sensor systems have been deployed to obtain georeferenced …

Measurement of plant and soil indices as well as their combinations are generally used for
irrigation scheduling and water stress management of crops and horticulture. Rapid and …

On-line measurement of soil compaction is needed for site specific tillage management. The
soil bulk density (ρ) indicating soil compaction was measured on-line by means of a …

How to evaluate the compaction quality in real-time, ie how to establish the relationship
between acceleration and dry density, is the key issue in the field of intelligent compaction …

There is a growing concern by governments, retailers and consumers about the safety and
quality of food. Because products are resourced on a on a global scale it becomes important …

A swinging arm type of frame height sensor was designed to measure the distance variation
between the soil surface and the frame of a sensor system developed for the online …

A combined horizontal penetrometer was designed for the on-the-go and simultaneous
measurement of soil water content and mechanical resistance. The maximum sampling rate …

Texture is one of the main properties affecting the accuracy of visible (vis) and near infrared
(NIR) spectroscopy during on-the-go measurement of soil properties. Classification of soil …

Using semivariograms and fractal dimension (D), we identified the spatial variation of
penetration resistance (PR) in variously compacted silty loam in the Lublin region, South …
