Abstract/ Executive Summary:

Terrace soil samples collected from Tangail District, Bangladesh, were analyzed to ascertain chemical properties and nutrient status. The study was conducted in the Tejgaon soil series, which is one of the dominant soil series of terrace soil. The soil is acidic and non saline. Fertility status of the topsoil is moderate but sub soil is low in fertility. The soil contains optimum amount of K, Fe, Cu and Mn but the amount of Ca, Mg, N, S, and B are not in optimum level. The fertility status of the soil is gradually decreasing. Phosphorous deficiency of soil is very much below critical level.

Program Area: Chemical Analysis

Commodity: Terrace soil, Nutrient status

Objectives:

This study was intended to find out the present status of chemical properties and nutrient status of terrace soils.

Methodology:

Topsoil (0-7cm) from 10 places were collected, mixed thoroughly to make a composite sample and 1 kg dry soil was taken from that mixture in a polybag. Pits of standard size (1m X 1m X 1m) were dug at 10 places with the help of spade for collecting horizonwise samples. Soil samples were collected from various horizons and kept in polybags separately. Thoroughly mixed the soils of same horizons. These samples were taken to laboratory, air dried in room temperature, grounded, passed through a 2 mm sieve and stored for analysis. Chemical properties of the soil samples were analyzed in the laboratory.

Achievement/Findings:

Terrace soil occupies about 8% area of the country and it has a great potential for supporting vegetation specially Shorea robusta. But it is degrading with the passage of time and becoming less suitable for the growth and development of vegetation. The fertility status of the soil particularly the top layer has already been aggravated and it will reach a critical level very soon. The following steps can be taken for the upliftment of the fertility status of soils of the study area: projects for afforesting the terraces should be undertaken to improve the vegetation cover, tree containing a large amount of leaves should be planted and all litters and twigs should be allowed to decompose in the forest for improving the fertility status of the soil. The moisture-holding capacity of the soil needs to be improved by providing vegetation cover and mulching. Different types of soil conservation practices can be adopted on the basis of Physico-chemical properties of soil.
