Optimal fertilizer application rates in container nursery crop production

Excess fertilization is not only costly but can also injure plants and cause unnecessary nutrient runoff, resulting in environmental damage. However, insufficient fertilization can result in plants showing symptoms of nutrient deficiencies, reduce crop productivity, and eventually reduce the efficiency of other resource inputs during nursery crop production.

Evaluation of turf fertilization run-off impact and mitigation techniques

A comparison of the effect of four different maintenance programs on turfgrass quality, nutrient losses through runoff and leaching, and soil fertility level. Twelve plots evaluated five different maintenance regimes that included aerification, topdressing, weed control and fertilization. Results suggest that fertilized turf uses less water than unfertilized turf.
