1. Chemical Factors Controlling the Adaptation of Weeping Lovegrass and Tall Fescue to Acid Mine Spoils

Author:
A. L. Fleming; J. W. Schwartz; C. D. Foy
Source:
Agronomy journal 1974 v.66 no.6 pp. 715-719
ISSN:
0002-1962
Subject:
Eragrostis curvula; Festuca arundinacea; aluminum; exchangeable aluminum; interspecific variation; land restoration; manganese; mine spoil; nutrient solutions; pH; plant response; root systems
Abstract:
... Successful revegetation of acid mine spoils can be facilitated by the use of plant species which can tolerate the existing growth-limiting conditions. Although species differences can be determined by growth on the particular spoil, specific knowledge of the plant response to each of the potential stresses will increase the reliability of the selection process. The objectives of this study were to ...

Abstract:
... Observations of weeping lovegrass (Eragrostis curvula (Schrad.) Nees) strains growing on a calcareous soil at Woodward, Okla., indicated differing degrees of susceptibility to a chlorosis tentatively attributed to Fe deficiency. To test this hypothesis thoroughly, we grew 41 strains in greenhouse pots containing a mixture of calcareous Millville and Quinlan soils, both of which were known to produ ...

Subject:
Eragrostis curvula; chlorosis; calcareous soils; acid soils; genotype
Abstract:
... Plant genotypes having greater tolerance to mineral stress are needed for use on problem soils. Two examples of such stress are mineral element toxicity (excess Al, Mn, etc.) in strongly acid soils and mine spoils, and Fe-related chlorosis in certain calcareous soils. Previous studies showed that genotypes of weeping lovegrass (Eragrostis curvula (Schrad.) (Nees) and Lehmann lovegrass (Eragrostis ...

Abstract:
... Moisture was the most important factor influencing the emergence of common bermudagrass (Cynodon dactylon (L.) Pers.) and weeping lovegrass (Eragrostis curvula (Schrad.) Nees.) in a clay soil over the range of bulk density and soil water pressure investigated. Both grasses exhibited approximately the same emergence at the −1/3 and −1-bar soil water pressures. Of those soil strengths and oxygen dif ...

Abstract:
... Yield responses by native range to fertilization has often been disappointing in the tall grass prairie, and the results were confounded by changes in species composition. This study evaluated the response to N and P fertilizer by monocultures of three native species ‘Kaw’ big bluestem (Andropogun gerardi Vitman), ‘Caddo’ switchgrass (Panicum virgatum L.), and indiangrass [Sorghastrum nutans (L.) ...

Abstract:
... Prescribed burning is a common management practice applied to weeping lovegrass [Eragrostis curvula (Schrad.) Nees], but little is known about tiller density and demographic response to burning. Our objectives were to determine fire effects on weeping lovegrass tiller density and demographics on a site, seeded in 1989, in western Texas. Tillers were sampled at 14-d intervals in 1996 and 1997 to de ...
