Evaluation of traditional methods for estimating lime requirement in Brazilian soils [PDF]
The optimal soil pH for most annual crops in Brazil varies between 5.7 and 6.0. Numerous methods have been developed for estimating lime requirement (LR), but they vary widely in their predictions and fail to raise pH to desired values for optimum crop ...

Land Clearing Effect on the Variability of some Soil Properties of an Alfisol in South-Western Nigeria [PDF]
The variability of some soil properties of a mechanically cleared plot was compared with an adjacent plot under natural vegetation in an Alfisol of South-western Nigeria. The soil properties studied were pH, total N, available P, exchangeable acidity Ca,

Cation Exchange Properties of Alginic Acid
SummaryAlginic acid possesses sodium and potassium ion exchange properties which compare favorably with those of a carboxylic type cationic exchange resin. Under in vitro conditions alginic acid at pH 7.6 adsorbs 4.2 meq Na+ per g. The total cation adsorption from solutions containing K+ and Na+ is also 4.2 meq/g and the ratio of Na:K combined ...
