Pasture site

Knapweed litter, collected from a severely infested site, was air-dried and ground to pass a 20-mesh screen. To determine the phytotoxicity of the litter, the ground material was applied to m plots on a pasture site in 1981 and on two rangeland sites in 1982. Sand (650 g) was combined with each knapweed treatment to produce an even dispersal of litter. The litter was applied in November and grass yields, estimated on a dry matter basis, were determined in the following June. 

In an initial study at the pasture site, replicate samples of dyed polyester, undyed wool, undyed cotton, and synthetic indigo-dyed denim were placed above (30 cm depth) and below (60 cm depth) cadavers and at 30 cm and 60 cm depth in control graves. When exhumed at 24 months, cadaver B was still actively decomposing with extensive adipocere formation at the base of the grave. This was confirmed by determination of carbon dioxide respiration rates for soil samples taken at the time of recovery (Wilson 2002). It was clear that decomposition of the cadaver had influenced the decomposition rates of the textiles depending on location in the grave after 24 months of burial (Table 7.6).

However, the most interesting of the Baccharis species is most certainly B. coridifolia. This plant is well-known in Brazil as being one of that country s most toxic plants (49) and is a serious hazard to livestock who graze in pastures populated by B. coridifolia (49). Four separate collections were made of B. coridifolia (48). Three of these collections were "From several miles outside Curitaba and a fourth collection in a pasture near Santa Maria, the site of an earlier collection of 13. coridifolia (47), and several hundred miles away from Curitaba. ThTs latter collection and two of the three former collections contained appreciable quantities of roridins A and E. A third collection from near Curitaba appeared to contain no macrocyclic trichothecenes. From a 20 g sample of one of the collections of B. coridifolia...

Copper absorption is depressed by ascorbic acid, dietary phytuies. cadmium, mercury, silver, and zinc. It appears that metals impede copper absorption through competition lor meml-hinding sites. Dietary copper, molybdenum, amt sulfur arc closely interrelated in optimum copper und molybdenum nutrition of ruminants. Increase pasture molybdenum content and low-pasture copper result in a condition known as "peat scours. ... 

Based on these results, Burger and Fajardo returned to the Aymaraes region in July 2004. Discussions with a farmer from near Chalhuanca, the provincial capital of Aymaraes, provided a lead to obsidian outcrops along a west-to-southwest winding road in the Huayllaripa drainage. The first outcrop was found at a site named Potreropampa or plain of pasture land about 32 km from Chalhuanca at an altitude of 4128 masl. Obsidian nodules were embedded in volcanic tuff and the nodules were mostly 3-6 cm in diameter but a few were up to 10-15 cm. A fair quantity of lithic debris was observed. 

Sometimes it seems like everyone wants you to put your baby down on plastic. So many things come wrapped in it—from conventional crib mattresses to pack-and-plays to bouncy seats. Our alternative to the ever-present vinyl waterproof pad is to use Pure Grow Wool as a wetness barrier. This wool is made from animals who grazed on pesticide-free pasture and ate chemical-free feed. Puddle pads can be found on many of the sites listed below. 

A series of experiments were set up in West Yorkshire, U.K., to test the relationships among the decomposition of buried hair, textiles, metal, and cadavers (pig) under a range of conditions relevant to regional depositional environments (Holland 2000 Wilson et al. 2007). Replicated cadaver and control graves (i.e., graves with experimental materials but without cadavers) were dug and exhumed after 6,12, and 24 months. Three experimental sites were used pasture, moorland, and woodland. These were chosen to complement each other in terms of altitude, soils, and drainage (Wilson 2002).

Fennel has become naturalized along roadsides, in pastures and in other open sites in many regions, including northern Europe, Cyprus, the USA, southern Canada and in much of Asia and Australia. It is propagated by seed and is considered a weed in Australia and the USA (Bown, 2001).
