Abstract

In Indonesia, soil carbon stock is very important managed on dry land that used to cultivate soybean. Conservation farming systems including various village and cropping system can be used to increase soil organic carbon content. The objective of research was to evaluate soil carbon stock on difference stage of soybean growth in various tillage and cropping systems. The research was arranged in randomize block design with 5 (five) treatments and 4 (four) blocks. The treatments were no tillage (NT) with mulch and soybean monoculture (P1); NT with mulch and mixing soybean-corn (P2); minimum tillage (MT) with mulch and soybean monoculture (P3); MT with mulch and mixing soybean-corn (P4); and intensive tillage and soybean monoculture (P5). The blocks were determined based on slope. Data were statistically analyzed with analysis of variance and Duncan New Multiple Range Test (α =0.05). The result of research indicated that on the planting stage, combination of difference tillage and cropping systems effect on soil carbon stock was no significant. Meanwhile, on early vegetative stage, NT with mulch and mixed of soybean-corn was better than conventional farming system to increase soil carbon stock on soybean farming. The result of research indicated that on maximum vegetative stage, NT with mulch and soybean monoculture was better than conventional farming system to increase soil carbon stock on soybean farming.
