In areas that remain unaffected by industrial pollution soil acidification is mainly caused by
the release of protons (H+) during the oxidation of carbon (C), sulphur (S) and nitrogen (N) …

Publisher Summary This chapter emphasizes on the effects that lime and phosphate
applications have on the soil–plant system. An understanding of such effects is essential for …

Root research under natural field conditions is still a step-child of science. The reason for
this is primarily methodological. The known methods are tedious, time consuming, and the …

This new edition of a bestseller examines plant nutrition's role as one of the most important
limiting factors that must be overcome to optimize food production. Extensively revised and …

Many agricultural soils worldwide in their natural state are deficient in phosphorus (P), and
the production of healthy agricultural crops has required the regular addition of P fertilisers …

This is a completely revised edition of the previously titled Solute Movement in the Soil-Root
System. It describes in detail how plant nutrients and other solutes move in the soil in …

In this book we describe in detail how plant nutrients and other solutes move in the soil in
response to plant uptake. The plants we consider may grow in isolation, or as a crop, a …

Supply and behaviour of NH4 and NO3 in the soil and processes of release, mechanisms of
N uptake in plants, factors affecting NH4 and NO3 uptake, general features of N nutrition and …

Plants that absorb nitrogen as NO 3− tend to raise the pH in the rhizosphere. Those
absorbing nitrogen as NH 4+ or N 2 lower the pH. The change in pH near the root surface …

Under areas where rainfall exceeds evapotranspiration, soil acidification is an ongoing
process that can be either accelerated by the activity of plants, animals, and humans or …
