The main objective of this study is to describe soil pore systems by entropy concept derived from the soil water retention characteristics related to soil structure modification. The proposed approach was evaluated with data from literature regarding to soil structure changes due to 1) compaction and 2) planting or irrigation cycles. While parameters of soil pore size distributions estimated from the soil water retention data responded variously depending on the type of soils, soil entropy for compacted soils from all data considered decreased as bulk density values increased. Similarly, soils after applying a series of irrigation or planting showed the consistent trend in the response of soil entropy. The advantage of soil entropy over other parameters derived from water retention curves is that it combines in one measure the two statistics defining a pore size distribution (i.e., geometric mean and standard deviation). Processes in soil such as compaction affecting pore system and their distribution could be effectively characterized by entropy. However, a potential disadvantage is that entropy cannot separate the effects of texture from the effects of soil structure making difficult the comparison across soil types.
