Tea is Bangladesh's second-highest agricultural export earner, and the nation rated 15th among all tea-exporting nations. To develop support tea business in Bangladesh, it crucial to comprehend current nutrient status of soils. The purpose study was examine inherent physical chemical characteristics soils relation effects soil depth, topography cultivation periods. results showed significant de...
in order to study the effects of climate and geomorphology on the development of soils and their physico-chemical peroperties, two transects on the loess parent material were selected in two regions of golestanprovince. the regions were: huttan (maraveh tappeh area) and gorgan with aridic-thermic and xeric-thermic soil moisture and temperature regimes, respectively. four pedons in hutan and fiv...
Surface charge of soils is measured using two different approaches: ion adsorption and potentiometric titration. Most models of surface charge chemistry of soils have been derived from the data obtained by potentiometric titration. The Uehara and Gillmanُs model was used to estimate the surface charges at some soil pH range in three forest soils of Lahidjan region. The selected soils (Typic Udor...
Phosphate sorption by soils is one of the most important processes indicating the buffering power and availability of P for plants. Phosphorus sorption characteristics of eight representative calcareous soil of Isfahan region were evaluated. For this purpose, 3 grams, of < 2-mm soil were equilibrated for 24 hours at 25±l °C in 60 ml of 0.01 M CaCl2 with varying amounts of P. Sorbed phosphorus w...
While grassland restorations have gained recent popularity throughout the United States, few restorations have been initiated on the highly weathered soils of the Mid-Atlantic Coastal Plain; thus potential soil response to grassland management practices, such as prescribed burning, are not clearly understood in this region. The objective of this study was to evaluate the impacts of prescribed b...
