Abstract

An experiment was conducted at the college of Agricultural and Environmental Science – Gedaref University demonstration farm – Sudan, to study the effect of humic substances (Elixir) on the soil salts content (electrical conductivity) and soil pH. Elixir 90 ml and 190 ml were applied to soil at two incubation periods (15 and 30 days). At the end of each period, the readings of soil EC and pH were measured. The results show that the average of soil EC obtained after 15 days by using Elixir 95ml (E1) and 190ml (E2) was 1.32 and 1.42 dS/m respectively, compared with control (E0) 1. 71 dS/m. The average of soil EC obtained after 30 days by using Elixir 90ml (E3) and 190ml (E4) was 1.11 and 1.32 respectively. The statistical results indicated that the application of Elixir reduced the soil EC and E4 has a good value in lowering soil EC than other treatments. On the soil pH, the average was 8.07, 8.27, 7.05 and 8.16 for E1, E2, E3 and E4 respectively compared with control (E0) 9.01, the statistical results showed that the addition of Elixir also reduced the soil pH. The E4 showed a high efficiency in reducing the soil pH. It can be concluded that the addition of Elixir 90 ml can be recommended for reducing the soil salts and pH.
