In the farm technology, some plants not only have corresponding planting soils (for example: sugarcane requires sand/red sand, hell warts require soul sand), but also attractives (for example: iron leaf grass needs iron ore).The crops that are generally required to be "bottom" are under the soil, and the scope of crops (for example: mercury flower seeds need silver trees) with "nearby".Plants in this range can grow (except for factors such as water, light source and other factors).
