Natural intoxication caused by protodioscin in lambs kept in Brachiaria pastures
Tropical Animal Health and Production, 2021Protodioscin poisoning of Brachiaria spp. has been a serious problem for lambs in grazing systems. The defoliation process can stimulate the appearance of new leaves and, the younger leaves have a lower concentration of protodioscin. Thus, it was aimed to assess the effect of different leaf offerings on the protodioscin content in forage and if ...

Grazing management of natureal pastures at Trangie, NSW
Australian Journal of Agricultural Research, 1956Results of a 5-year grazing experiment on Stipa-Chlaris natural pasture are presented. Treatments were three rates of stocking each tested with continuous grazing, autumn deferment, and spring deferment. These were studied in relation to: (a) body weight and wool production of Merino wethers; (b) available feed; (c) density and basal area of the ...

Effects of Lime and Fertilizer on Natural Pastures in Brazil
Experimental Agriculture, 1975SUMMARYThe application of lime to natural pastures in Rio Grande do Sul, Brazil, did not increase herbage yields, but nitrogen fertilizer, alone and in combination with phosphorus fertilizer, enhanced dry matter productivity significantly. Dry matter yields of the natural pasture were more than doubled at the highest fertilizer rate, though the ...

The role of natural disturbances in a pasture.
2023Seedling survival of species Trifolium pratense and Achillea millefolium was observed in microsites, such as molehills, anthills, wild boar disturbances, and artificial gaps at a pasture. In this thesis, we observed the influence of vegetation, litter, mosses, stones, bare soil cover, moisture, and temperature on seedling survival.

The effect of environmental factors on the growth of a natural pasture
Agricultural Meteorology, 1975Abstract In order to study the dependence of growth curves of a natural pasture on environmental factors, logistic equations in which the growth rate R is a function of soil moisture or temperature are used. The parameters that appear are optimized by a nonlinear least-squares technique. Soil moisture is an important variable.

The communities and diversity of the beneficial insects on jujube trees were studied in jujube sites intercropped with pasture in Taigu, Shanxi province of China. The results showed that 8 orders, 25 families, 64 species and 5112.33plusmn30.65 individuals of insect natural enemies were found in the jujube sites intercropped with pasture site, while the

Molecular Diversity of the Rumen Microbiome of Norwegian Reindeer on Natural Summer Pasture
Microbial Ecology, 2008The molecular diversity of the rumen microbiome was investigated in five semi-domesticated adult female Norwegian reindeer (Rangifer tarandus tarandus) grazing on natural summer pastures on the coast of northern Norway (71.00 degrees N, 25.30 degrees E). Mean population densities (numbers per gram wet weight) of methanogenic archaea, rumen bacteria and

Soil as a factor of vegetation regeneration in natural pastures
Russian Journal of Ecology, 2011Data are presented that show the significance of the humus state of chernozem soils, their amphiphilic (hydrophobic-hydrophilic) components, and related physical properties (density, structural condition, and water permeability) for regeneration of natural vegetation and restoration of its species com-position in pasture ecosystems.

Management of natural Kentucky bluegrass-white clover pasture
American Journal of Alternative Agriculture, 1997AbstractManagement recommendations are needed f or low-input (no N fertilizer) Kentucky bluegrass-dominant/white clover swards, particularly to increase or maintain white clover content. We applied treatments involving different amounts of forage present pre- and postgrazing, with and without harrowing and soil aeration, to a well-established ...

EFFECTS OF IRRIGATION AND NITROGEN ON A NATURAL PASTURE SWARD
Canadian Journal of Plant Science, 1978Irrigation and nitrogen (N) requirements of a natural pasture sward were studied on a Charlottetown sandy loam soil over a 5-yr period. The soil moisture content at the 0-to 15- and 15- to 30-cm depths was determined at from 7- to 10-day intervals, while irrometer soil moisture readings at 15-, 30-, and 45-cm depths were recorded more frequently ...
