COMPARATIVE STUDY OF THE VARYING EFFECT OF MOISTURE DEFLECTION AND BULK DENSITY ON SOIL RESISTANCE TO PENETRATION ON TWO AGRICULTURAL SOIL IN FEDERAL POLYTECHNIC, BAUCHI.
Abstract
This study investigates the comparative effects of moisture deflection and bulk density on soil resistance to penetration in two selected agricultural soils within the Federal Polytechnic Bauchi environment. The research aims to determine how differences in soil moisture and compaction influence the ease with which roots and agricultural implements penetrate the soil, thereby affecting crop performance and tillage efficiency. Soil samples were collected from two distinct locations representing different textural classes and moisture regimes. Laboratory and field analyses were conducted to determine soil moisture content, bulk density, and penetration resistance using a cone Penetrometer. The results revealed that soil resistance to penetration increases with higher bulk density and decreases with rising moisture content. However, the magnitude of this relationship varied between the two soil types due to differences in texture and structure. Statistical analysis confirmed a significant correlation between soil moisture, bulk density, and penetration resistance. The findings suggest that managing soil compaction and moisture balance is essential for optimizing tillage operations and promoting better crop root development in the study area.
