*2.1.2 Land preparation using perfect tillage carried out by farmers*

The process of harvesting rice in paddy fields using combine generally compacts the soil, making it difficult to plant soybeans using the zero tillage method. To fertilize their land, some farmers use tractors. The use of 4-wheel tractors for tillage is only carried out by farmers who have a lot of farming costs. This is because the cost of cultivating the land using a 4-wheel tractor costs Rp. 1,350,000 per hectare. Meanwhile, planting soybeans using the zero tillage method only costs around IDR 450,000–600,000 per hectare.
