Nitrogen and iron fertilization of bentgrass1

  1. V. Snyder and
  2. R.E. Schmidt

Abstract

Fall-winter applications of nitrogen increased spring clipping yields and root growth of creeping bentgrass (Agrostis palustrus Huds.), and improved turf grass appearance. Applications of iron made in combination with nitrogen further enhanced appearance, chlorophyll content, and early spring shoot growth, and appeared to offset the injurious effects of heavy fall-winter nitrogen.

Root growth was influenced by rate and time of application of nitrogen and iron while differences due to iron sources were noted. Spring and summer applications of nitrogen were beneficial to turfgrass color and further enhanced turf vigor when coupled with iron fertilization. Additional index words: Iron chelate, Fall fertilization, Foliar application, Plant growth, Winter desiccation, Agrostis palustrus Huds.
