At 167 buffelgrass seeding sites in North America we collected climatic and soils data where the grass:  1) persisted over time and increased in area covered (spreads), 2) persisted over time but does not increase in area covered (persists), and 3) declined over time and all plants eventually died (dies).  At 30 sites in Kenya we collected climatic and soils data in the area where T-4464 seed was originally collected.  Only total soil nitrogen and organic carbon differed among survival regimes.  Total soil nitrogen and organic carbon concentrations were least where buffelgrass spreads, intermediate where the grass persists and greatest where the grass dies.  To predict buffelgrass survival among the 3 survival regimes, and between areas where the grass spreads or dies, we used discriminant function analyses.  A model including organic carbon, total soil nitrogen, sand, clay, potassium and cation exchange capacity correctly classified 78% (r2 = 0.8) of the seeding sites in the 3 survival regimes.  A model including sand, total soil nitrogen, calcium, mean minimum temperature in the coldest month, annual precipitation and winter precipitation correctly classified 88% (r2 = 0.8) of the seeding sites between spreads and dies.  Survival regime selection prior to brush control, seedbed preparation and sowing will reduce planting failure probabilities, soil erosion and economic losses, and enhance long-term beef production.</style></abstract><accession-num><style face="normal" font="default" size="100%">ISI:A1995QA49600007</style></accession-num><notes><style face="normal" font="default" size="100%">Qa496Times Cited:15Cited References Count:37ISI Document Delivery No.: QA496Times Cited: 15Cited Reference Count: 37Cited References: 1954, USDA AGR HDB, V60 1975, SOIL MAP WORLD, V2 1977, SOIL MAP WORLD, V6 1982, CLIMATOGRAPHY MEXICO 1984, AGROCLIMATOLOGICAL D 1985, CLIMATOGRAPHY US 1988, SAS PROCEDURES GUIDE AGOSTINI JJ, 1981, AGRONOMIA, V200, P42 ANDERSON ER, 1972, QUEENSLAND J AGR ANI, V29, P167 ANDERSON ER, 1974, TROPICAL GRASSLANDS, V8, P33 BALL DE, 1964, J RANGE MANAGE, V17, P217 BOGDAN AV, 1961, E AFR AGR FORESTRY J, V26, P241 BRZOSTOWSKI HW, 1962, TROP AGR TRIN, V39, P289 BRZOSTOWSKI HW, 1964, TROP AGR TRIN, V41, P231 CHRISTIE EK, 1975, AUST J EXP AGR ANIM, V15, P239 COALDRAKE JE, 1969, TROP GRASSLANDS, V3, P49 COTA A, 1975, ADAPTATION PRODUCTIO COX JR, 1988, J RANGE MANAGE, V41, P127 DAY PR, 1950, SOIL SCI, V74, P81 DUTOIT J, 1976, 5TH P GRASSL SOC AFR, V8, P107 EBERSOHN JP, 1970, TROPICAL GRASSLANDS, V4, P37 GONZALEZ CL, 1979, J RANGE MANAGE, V32, P305 GONZALEZ CL, 1981, J RANGE MANAGE, V34, P460 HACKER JB, 1989, J APPL ECOL, V26, P213 HANSELKA CW, 1985, BUFFELGRASS ADAPTATI, P53 HOLT EC, 1985, MP1575 TEX AGR EXP S, P1 HUMPHREYS LR, 1967, TROP GRASSLANDS, V1, P123 JACKSON ML, 1958, SOIL CHEM ANAL KHAN SM, 1982, PAKISTAN J FORESTRY, V32, P89 MANNETJE L, 1990, TROPICAL GRASSLANDS, V24, P269 MOLINA SI, 1976, TECNICA PECUARIA MEX, V31, P17 OLSEN SR, 1982, METHODS SOIL ANAL 2 SILCOCK RG, 1990, TROP GRASSLANDS, V24, P65 WALKER B, 1990, TROP GRASSLANDS, V24, P257 WILSON RG, 1964, QUEENSLAND AGR J, V90, P286 WINER BJ, 1971, STATISTICAL CONCEPTS ZAR JH, 1984, BIOSTATISTICAL ANALSoc range managementDenver</style></notes><auth-address><style face="normal" font="default" size="100%">Ibarraf, FaUtah State Univ,Dept Range Sci,Logan,Ut 84322Utah State Univ,Dept Range Sci,Logan,Ut 84322Ctr Invest Pecuaries Estato Sonora,Sonora,MexicoTexas a&amp;M Univ,Agr Ctr Res &amp; Extens,Vernon,Tx 76305Utah State Univ,Dept Range Sci,Logan,Ut 84322Utah State Univ,Dept Fisheries &amp; Wildlife,Ctr Ecol,Logan,Ut 84322Utah State Univ,Us Forest Serv,Forage &amp; Range Res Lab,Logan,Ut 84322Usda Ars,Tucson,AzUsda Ars,Logan,UtUtah State Univ,Watershed Sci Unit,Logan,Ut 84322</style></auth-address></record></records></xml>
