Models of Duricrust Formation in Tropical and Subtropical Areas

2022
<div>Ferruginous duricrust formation takes place by dissolution and accumulation of iron during the wet season and precipitation during the dry season. However, the formation of iron duricrusts has always been the centre of much debate. They commonly form as hard iron layers in tropical and subtropical environments with strong climatic ...

Comparing Models for Duricrust Formation in Tropical and Subtropical Areas

2023
Duricrusts are hard elemental layers forming in tropical and subtropical regions. Different types of duricrusts exist, including calcretes, silcretes and ferricretes (or iron duricrusts), that differ by their composition and, most likely, their formation mechanism.

The Impact of the Green Revolution on Plant Protection in Tropical and Subtropical Areas

Bulletin of the Entomological Society of America, 1972
The earliest use of the term “integrated control,” at least in its pest control sense, dates from June of 1954 (Smith and Allen, 1954). Thus, the history of integrated control would appear to have spanned little more than 17 years. Until now, most discussions of the origins of integrated control have emphasized the over-dependence on and the over-use ...
