Elj. Watkin et al., Identification of tolerance to soil acidity in inoculant strains of Rhizobium leguminosarum bv. trifolii, SOIL BIOL B, 32(10), 2000, pp. 1393-1403
The acid-soil tolerance of six strains (WU95, NA3001, WSM409, TA1, NA3025 a
nd NA3039) of Rhizobium leguminosarum by. trifolii was assessed in a three-
year cross-row field experiment in an acid sandy soil of pH 4.2. Strains WS
M409, NA3039 and WU95 were more acid-soil tolerant than strains NA3025, TA1
and NA3001. Strains WSM409 and NA3039 colonised and persisted in acid-soil
to a greater degree than strains TA1 and NA3001. The data from this study
clearly identified strain WSM409 as a strain with outstanding potential for
improving the production of clovers on acid soils. (C) 2000 Elsevier Scien
