Abstract: The invention relates to crop netting materials, crop cover materials, and ground cover materials that transmit solar radiation in the visible wavelength range of about 420 to 720 nm at a level similar to the level that the materials transmit solar radiation in the infra red wavelength ranges of about 700 to about 1000 nm and 1500 to about 1600 nm. The materials also absorb solar radiation in the UV wavelength range of about 300 to about 380 nm.

Abstract: The invention relates to crop netting materials, crop cover materials, and ground cover materials for agricultural applications, which is knitted, woven or non-woven, from a synthetic monofilament, multifilament yarn, or tape or combination thereof, formed from a resin comprising at least one pigment such that the monofilament, multifilament yarn, or tape, transmit solar radiation in the visible wavelength range of about 420 to 720 nm at a level similar to the level that the materials transmit solar radiation in the infra-red wavelength ranges of about 700 to about 1000 nm and 1500 to about 1600 nm. The materials also absorb solar radiation in the UV wavelength range of about 300 to about 380 nm.

Abstract: A fabric roll up core for carrying rolls of sheet material such as ground covers or canopy sheet materials including netting materials, used in agriculture or horticulture, such as bird, insect, hail, shade, wind barrier netting materials, comprises a profile formed in an outer surface that assists in maintaining the sheet material on the fabric roll up core when rolling the sheet material onto the fabric roll up core and which may be effective to work with roll up drive means. The core may be formed in one piece or as multiple connected parts.

Abstract: The present invention relates to ground cover sheet materials and to ground cover sheets comprising such materials. The ground cover sheet material absorbs more solar radiation than it reflects in the UV range of about 280-400 nm, and reflects more solar radiation than it either transmits or absorbs in the visible range of about 400-700 nm and near infrared range of about 700-800 nm, and transmits at least part of solar radiation in the range about 800-2500 nm and at least part of solar radiation above about 2500 nm.

Abstract: A ground cover sheet material for use in agriculture is described. The sheet material has a greater length than width and is woven from at least two different types of tapes. The two different types of tapes have different reflecting, absorbing or transmission properties. Each type of tape forms at least 5% or 10% of the surface area of the ground cover material.

Abstract: The present invention relates to ground cover sheet materials and netting materials, and to ground cover sheets and netting comprising such materials. The materials comprise a green pigment derived from one or more pigments, and at least one additional pigment which does not significantly decrease the amount of solar radiation transmitted by the polymer-pigment mixture in the range of about 700 nm-2500 nm, and/or at least one additional pigment which decreases the amount of solar radiation transmitted by the material in the blue light range of about 440 nm-490 nm and in the red light range of about 620-700 nm.
