The basic objectives of site-specific management of agricultural inputs are to increase
profitability of crop production, improve product quality, and protect the environment …

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 …

The driving force behind putting this book together was twofold. First, the world's population
has reached the 7 billion mark and is set to increase to around 9 billion by 2050, pressure …

Soil and plant sensing can be separated into remote sensing, which is discussed in Chapter
8, and proximal sensing, where an instrument is placed within 2 m of the target (Viscarra …

The intimate knowledge of soils with regard to their nature, extent, spatial distribution,
potential and limitations is a prerequisite for sustainable development of natural resources …

In this review, we have evaluated several methods and recent technologies to determine the
soil nitrogen, phosphorus, and potassium (NPK) content to increase yield production …

Abstract Development of simple and economical sensors to measure the soil physical
properties is of great importance in precision agriculture. Building on a previous study with a …

Precision agriculture is drawing widespread attention and increasing interest in the use of
on-the-go sensors to extract soil and plant information. This new trend is evident from an …

One of the most significant soil parameters affecting root growth is soil compaction. It is
therefore important to be able to determine the presence of compacted layers, their depth …

Although the first prototype of a soil compaction profile sensor (SCPS) developed at the
University of California Davis performed well in terms of sensing variation in soil compaction …
