The object of the present invention is to maintain a high light transmittance, while maintaining the growth of crops and the internal visibility by growers, and the growth promotion effect by keeping the ground temperature is good, and the excessive infiltration of rainwater can be suppressed. In addition, the present invention provides an agricultural covering material that has excellent uniformity such that there is no unevenness in strength and good prevention of insect pests, and also has appropriate air permeability, and (i) a light transmittance of 80% or more, (Ii) An agricultural covering material comprising a nonwoven fabric laminate having an air permeability in the range of 50 to 400 cm 3 / cm 2 / sec and (iii) a basis weight in the range of 10 to 30 g / m 2 .本発明の課題は、高い光線透過率を維持することにより、作物の成育促進や栽培者による内部視認性を維持しつつ、地温の保温による成育促進効果が良好で雨水の過度な浸入を抑制でき、かつ、強度ムラが無く害虫の飛来防止も良好といった均一性に優れ、合わせて適切な通気性も兼ね備えた農業用被覆材を提供することであり、（ｉ）光線透過率が８０％以上、（ii）通気度が５０～４００ｃｍ3／ｃｍ2／ｓｅｃの範囲、および（iii）目付けが１０～３０ｇ／ｍ2の範囲にある不織布積層体からなる農業用被覆材である。
