Shading a rundown green panic pasture stimulated greater growth and higher nitrogen (N) concentration of the green panic compared with adjacent plots in full sunlight. The pasture was 16 years-old and located on a grey, brown and red clay Brigalow soil in southern Queensland. The shades ("sarlon" cloth transmitting 37% light) were in place over two growing seasons.
