Agricultural liming is a central issue in tackling soil acidity problems in tropical soils. A study on liming in a 1,845.2 ha sub-watershed Kemuning, Jember employing Exchangeable Alumunium (Al-dd) and Effective Cation Exchange Capacity (eCEC) methods. Our results showed that the average need for lime is 0.26-3.2 tons/ha in calcite and 0.9-3.5 tons/ha in dolomite form based on the Al-dd method. Furthermore, using the Effective CEC method, the average need for lime is 1.2-3.2 tons/ha. Based on the Al-dd way, there is an area of 336.4 ha that requires lime of 470.9 tons, while using the effective CEC method, there is a 676.2 ha area that takes lime 946.7 tons. There are differences in the location and amount of lime required in the two calculation methods. [ABSTRACT FROM AUTHOR] |
