Standard Fertilization and Liming as Factors in Maintaining Soil Productivity

The basaltic soils of SE Nigeria: properties, classification and constraints to productivity

“…However, some crop plants growing on acid soils are presumed to be tolerant to the acidity condition. Such plants are believed to possess a higher feeding power than those growing in neutral or alkaline soils, and are better able to utilize the small quantities of readily soluble plant nutrients present in such acid soils (Aslander, 1952). Although liming is a common agricultural practice to neutralize exchangeable Al and increase soil pH, this measure was not considered appropriate for the basaltic soils examined for the following reasons: (a) Danger of overliming by the largely illiterate farming population, and the attendant ill-effects on crop growth and yield.…”

Opening History: Gaining Perspectives

“…Next in the mid-twentieth century, especially Chaminade [106][107][108][109][110][111][112] studied many aspects. Independently it was studied by Åslander, a Swedish researcher who focussed at phosphate fertilisation of the acid peat lands common at Northern latitudes [113][114][115][116]. Composted fertiliser with rather small amounts of phosphate sufficed, and no chalk was needed.…”

Mineral nutrition of forest tree seedlings

“…In an earlier paper, Wilde (1934) concluded that soil reaction affects the growth of tree seedlings primarily by in fluencing the availability of nutrients, potency of toxic agents, ac tivity of useful and parasitic soil organisms, and physical conditions o of the soil. Aslander (1952) also has concluded that it is a lack of plant nutrients and not an acid reaction that makes an acid soil un productive.…”
