Abstract/ Executive Summary:

Inositol phosphate, phospholipid, ribonucleic acid and deoxyribonucleic acid along with their derivatives decreased gradually with depth in the profiles, while their variable amounts were jointly correlated with organic phosphate, total phosphate, organic matter, total nitrogen, pH and clay content of the soil. However, individually inositol phosphate was significantly correlated with phosphate, organic phosphate, organic matter, pH, and clay content at the 0.1% level, and ribonucleic and deoxyribonucleic acids and their derivatives with organic phosphate and organic matter at the 5 and 10% level respectively while phospholipids with none of the factors studied.

Program Area: Crop-Soil-Water Management

Commodity: Soil fertility

Objectives:

To determine the relationship of organic phosphate compounds in some soil profiles with selected soil properties of Bangladesh.

Methodology:

Six soil series selected randomly were identified on the basis of the parent material, drainage condition, sub-surface texture and colour. pH was measured electromagnetically by using a pye glass electrode the soil : water ratio being 1:2, 5. Mechanical analysis was done by their hydrometer method, organic matter was calculated by multiplying the values of organic carbon by 1.72 where as organic carbon was estimated, The different method was used for determining organic and total phosphate, Inositol phosphate, ribonucleic acid and its derivatives, deoxyribonucleic acid and its derivatives, etc.

Achievement/Findings:

In order to assess the reasons for varied amounts of these compounds in the profiles, single and multiple correlation studies were made. These studies suggested that all these factors contributed together for their varied distribution in the profiles. However, individually inositol phosphate was significantly correlated with organic phosphate, organic matter, pH and clay at the 0.1% level. Ribonucleic and deoxyribonucleic acids and their derivatives were significantly associated with organic phosphate and organic matter at the 5 and 10% level respectively. However, phospholipids were found to be significantly correlated with none of these factors under investigation.
