Compost application and disease suppression

Article Abstract:

Research at Cornell University has proven the fungicidal action of compost on turfgrass root-rotting disease caused by Pythium spp. and other pathogens. The results of field experiments, which focused on creeping bentgrass root-rot, indicate that microbial activity in the compost is responsible for pathogen suppression. Further research is needed to identify the beneficial microorganisms in the compost as well as to characterize their physiology and ecology for optimum fungicidal effects.

Compost application improves soil properties

Article Abstract:

MSW compost is 50% organic matter, which increases the properties of soil. MSW enhances the water-retention property of soil, and reduces soil bulk density. It is neutral to alkaline in pH, and when applied in large doses, MSW increases the cation exchange capacity (CEC) of soil, while in small doses it has little effect. MSW has a low risk value of phytotoxicity, which is further reduced by ploughing and irrigation.

Disease suppression on the links

Article Abstract:

Compost is better than peat for golf courses even though it does comply with USGA standards. Compost, unlike peat, improves the microbial activity and moisture content of the soil. It is well suited to fill divots and costs around 12 US dollars per year to purchase. The course maintenance tasks involving compost at the North Shore Country Club in Illinois and at the Stanley Golf Course in Connecticut are described.
