[Problem] To keep down the costs required to prevent disease and insect pests when cultivating plants. [Solution] This agricultural mat 1 comprises a bottom plate 2, a cover member 3 covering the bottom plate, a hole 3a penetrating the cover member in order for an internal space 4 formed by the bottom plate and the cover member to communicate with the outside, sulfur powder 5 accommodated in the internal space, and a means 6 for the sulfur powder to be in contact with soil 10 when the bottom plate is placed on the soil. The means for sulfur powder to be in contact with the soil may be formed from an opening 2a formed in the bottom plate and a sheet 7 covering the opening and having the sulfur powder placed thereon. A cup 8 may also be provided, which is configured such that while the sulfur powder is accommodated therein, an open bottom portion of the cup comes into contact with the paper, and which has a hole 8a to cause the space accommodating the sulfur powder to communicate with the internal space formed by the bottom plate and the cover member.
