| Abstract:
The primary concern of golf course superintendents is the maintenance of turfgrass quality on facilities subjected to regular close grass mowing and high traffic levels. Combined, these factors create stress on plants. The problem is compounded by the use of inert sand based media, which in contrast to sand/soil greens have a poor buffering capacity and require high quantities of nutrients and irrigation. Several products such as seaweed extracts have been developed to help turfgrass managers to maintain high turfgrass quality in the face of these many problems. This research was initiated to study the impact of applying a seaweed extract onto a turfgrass sward grown under reduced nutrient input rates. Tissue and soil nutrient measurements, grass growth, colour and stress tolerance levels were measured. The application of seaweed extract significantly increased grass growth, leaf tissue N, P, K and Fe, grass colour and stress tolerance levels. | |
