Abstract:
Iron deficiency is often a serious problem in common bermudagrass ( Cynodon dactylon L.) grown on calcareous soils. This study was carried out in order to determine the effects of applications of sulfuric acid, an abundant material from the copper industry, on bermudagrass grown on calcareous iron‐deficient soils. Cave (Typic Paleorthid) and Stewart (Typic Nadurargid) soils were placed in pots and sulfuric acid was applied 1) to the soil surface, 2) mixed with the soil, 3) as a band, or 4) localized as spots prior to seeding. Ferrous sulfate, iron chelate (Fe‐EDDHA), and an iron‐bearing copper refining byproduct, “jarosite”, were included for comparison. The 93% H 2 O 4 was the most effective material in increasing growth of the plant material by alleviating iron deficiency, the effect decreasing for the first four of seven harvests over a 1‐year period. There was no difference between H 2 SO 4 application methods at equivalent rates. Surface‐applied H 2 SO 4 increased chlorophyll concentrations in the plant with increasing rates but was not as effective as either FeSO 4 7H 2 O or Fe‐EDDHA. Application of 3% H 2 SO 4 in the irrigation water was as effective as these materials in alleviating chlorosis on a series of previously untreated pots. Results indicate that H 2 SO 4 may be useful for treating iron‐deficient bermudagrass, a common turf and seed crop in the Southwest.
