Soil compaction influences soil hydraulic properties water flow and solute movement. The objective of this study was to investigate the movement of the added fertilizers to soil as affected by soil compaction. In the experimented soil four compaction levels were used. Each column of soil was divided in to six equal parts where the elements in the columns were measured. The data were then analyzed using the statistical software SAS. Results showed that as the compaction is increased the downward movement of nitrogen N and potassium K downward were reduced but increased for phosphorus P. The reason for this was because the movement of N in low compaction was due to the existence of macropores for preferential flow and suitable conditions for nitrification. The movement of K in low compaction is due to movement through macropores and preferential flow. The increase in P movement in high compaction was caused by high moisture and diffusion.

Abstract

Soil compaction influences soil hydraulic properties water flow and solute movement. The objective of this study was to investigate the movement of the added fertilizers to soil as affected by soil compaction. In the experimented soil four compaction levels were used. Each column of soil was divided in to six equal parts where the elements in the columns were measured. The data were then analyzed using the statistical software SAS. Results showed that as the compaction is increased the downward movement of nitrogen N and potassium K downward were reduced but increased for phosphorus P. The reason for this was because the movement of N in low compaction was due to the existence of macropores for preferential flow and suitable conditions for nitrification. The movement of K in low compaction is due to movement through macropores and preferential flow. The increase in P movement in high compaction was caused by high moisture and diffusion.
