PROBLEM TO BE SOLVED: To provide a film for farming capable of bringing a ground temperature equal to or less than the bare ground temperature, raising crops in a good cultivation environment, accelerating growth and reducing damages caused by other plant diseases by using the film for cultivating the crops during a high temperature period difficult to cultivate the crops. SOLUTION: This agricultural film is a multi-layer film comprising a polyolefin-based resin and specific in that one surface is a black color layer and the other surface is a white color layer, the product of the value of titanium dioxide concentration (wt.%) and the value of the thickness (μm) of the white color layer is >=500, holes having <=1 mm hole diameter are substantially uniformly made on the film surface and the whole area of the holes is >=1000 mm2 per 1 m2 of the film.
