“…Perennial lupin in both experiments became the dominant species at the lower fertiliser rates and is maintaining itself under the various stocking rates and methods, particularly the laxer sustained grazing management. The success of perennial lupin in acid, low P and high Al soils as well as its low P accumulation rates and preferential accumulation of Mn without toxic effects has also been reported by Davis (1981). The present trial has also shown its value on low S soils.…”

Species dominance and sheep grazing days relative to fertiliser costs are given for the first 6 years of 2 trials at Lake Tekapo. Both were sown in a multiple species mixture. Trial I examined 27 different annual P and S levels; Trial II examined 30 combinations of 5 superphosphate levels, 3 sheep grazing intensities and 2 stocking methods. Pastures were mostly legume dominant, and species differences were related to P fertiliser and stocking method. Perennial (Russell) lupin (Lupinus poflyphyllus) dominated at all low to medium fertiliser rates, alsike clover (Trifolium hybridum) at intermediate rates, and cocksfoot (Dactylis glomerata) and white clover (T repens) at high ferttliser rates. The stocking rate achieved was related to both S and P rates. Greatest fertiliser efficiency (returns v. costs) was at low annual rates of 4-5 kg P plus 16-25 kg S/ha. Keywords: lupin, cost-benefit, cocksfoot, alsike clover, phosphate, sulphur, sheep grazing management, fertiltser efficiency.

“…Moreover, there is a lot of evidence showing pasture growth depression when soils with pH greater than 6.0 are limed. These negative effects mainly result from lime-induced P and Mg deficiencies (Sumner et al 1978), or a decrease in the availability of micronutrients (Davis 1981;Manselletal. 1984).…”

Linz-Donawitz (LD) slag, containing 29% calcium (Ca), 21% iron (Fe), and 5% magnesium (Mg), is a by-product of the iron and steel-making industry. It is produced in large quantities in Europe and poses a substantial disposal problem. A field trial was conducted to study whether LD slag could be used as a dolomitic liming agent for pastures. The effects of six LD slag rates (0, 1000, 1500, 3000, 5000, and 7500 kg LD slag/ha), with or without NPK fertiliser, on soil properties, pasture yield, and botanical composition were investigated at two locations, Derio and Abadiano (Bizkaia, northern Spain). Soil at Derio was a fine silty, mixed (acid), mesic Typic Udorthent and at Abadiano a fine loamy, mixed (nonacid), mesic Aquic Udifluvent. At Derio, the 3-year trial was laid out on a newly established pasture of perennial ryegrass (Lolium perenne L.), cocksfoot (Dactylis glomerata L.), and white clover (Trifolium repens L.), whereas at Abadiano the trial was on a resident pasture dominated by yorkshire fog (Holcus lanatus L.) and browntop (Agrostis tenuis Sibth.). Application of LD slag increased the soil pH linearly at both sites. At A94050 Received 2 May 1994; accepted 15 November 1994Derio, the 7500 kg slag/ha rate increased the soil pH from 5.3 to 6.4, whereas at Abadiano the pH was raised from 5.7 to 6.5 and from 5.8 to 6.7 with and without NPK fertilisation respectively. The increase in pH was accompanied by a decrease to less than 5% in the percentage of Al saturation in the cation exchange complex. At Derio, soil exchangeable Ca increased in comparison with the control, by a factor of 1.8 and 2.3, with and without NPK fertilisation, respectively. At Derio, pasture yield increased with slag application, the second year responses being the largest (41% increase with 3000 kg slag/ha). At Abadiano, pasture yield did not respond to slag, but the botanical composition changed, with the contribution of browntop and yorkshire fog decreasing, and the contribution of red fescue (Festuca rubra L.) and ribwort (Plantago lanceolata L.) increasing. According to the results, LD slag appears to be a useful liming material for correcting soil acidity on pasture soils. As a consequence, the agronomic use of LD slags will contribute towards solving the environmental problem of their disposal.

. 2006. A review of research progress on cicer milkvetch (Astragalus cicer L.). Can. J. Plant Sci. 86: 49-62. This review of cicer milkvetch includes both published and unpublished information regarding crop and seed characteristics, seed treatments, breeding, agronomic practices and nutritional value for livestock. Cicer milkvetch is a long-lived perennial, acid-and drought-tolerant crop providing high-quality forage throughout the growing season. It does not cause bloat in ruminants. Although it has caused photosensitization in ruminants, this was apparently due to specific environmental conditions and the cultivar used. Cicer milkvetch is compatible with other forage crops in mixed stands and is particularly suitable for pasture. Although the crop has many good qualities and was introduced in North America approximately 75 yr ago, it has not been utilized extensively, primarily due to slow establishment. However, stand establishment has been improved by elucidation of seed and seedling characteristics, followed by selection for heavy seed, rate of emergence, and mature plant vigor. Improved cultivars, developed through recurrent selection for rapid establishment, are now available. Seed scarification, inoculation with rhizobia, and shallow seeding into a pre-packed, warm seedbed are of great importance in cicer milkvetch establishment. Seeding later in the spring (without a companion crop) increases the probability of successful establishment of genetically improved cultivars. Development of cultivars with upright growth characteristics and long-term persistence under grazing stress, improved scarification techniques (to reduce seed loss), and a seeding protocol for successful establishment of the crop, have the potential to substantially increase utilization of this important forage legume. Cette revue bibliographique englobe l'information connue et inédite sur les caractéristiques de la plante et de la graine, les traitements grainiers, l'hybridation, les pratiques agronomiques et la valeur nutritive de cette culture pour le bétail. L'astragale est une vivace longévive qui tolère bien les sols acides et la sécheresse; elle produit un fourrage de haute qualité pendant toute la période végétative. Elle n'entraîne pas le météorisme chez les ruminants. La photosensibilisation qu'elle engendre à l'occasion chez eux semble résulter de certaines conditions environnementales ainsi que du cultivar employé. L'astragale est compatible avec d'autres plantes fourragères dans les peuplements mixtes et se prête particulièrement bien aux pâturages. En dépit de ses nombreuses qualités et de son introduction en Amérique du Nord il y a près de 75 ans, l'astragale n'est pas énormément utilisée, principalement parce qu'elle prend du temps à s'implanter. On peut néan-moins améliorer l'établissement de la culture en triant les semences et les plantules d'après leurs propriétés puis en sélectionnant les plants pour une production abondante de graines, le taux de levée et la vigueur des plants adultes. On trouve désormais sur le ma...
