Farmers/farming

Bioavailability from Environmental Media. Diazinon can be absorbed following inhalation, dermal, or oral exposures. Absorption through the skin is of major concern for exposures of farmers, farm workers, commercial applicators, or homeowners related to the use of diazinon as an insecticide or nematocide (Davis et al. 1983). Absorption via inhalation is a major concern particularly with respect to indoor exposures to diazinon within 2 days postapplication of the compound as a pest control agent in commercial buildings and homes (Currie et al. 1990 Jackson and Lewis 1981 Lenhart and Kawamoto 1994 Williams et al. 1987). Additional information on the concentrations of diazinon in indoor air and in groundwater from domestic wells, particularly from environments near hazardous waste sites, is needed to determine the bioavailability of diazinon in these media. 

Berry has never claimed that farmers of the past, conventional or organic, have ever achieved true harmony with nature or sustainability. He simply states that harmony in nature, as with harmony in society, must be achieved through loving relationships. The permanence of food and farming systems depends upon personal relationships of integrity and trust among farmers, farm workers, eaters and citizens within local communities. 

Although the benefits of transgenic crops to consumers are somewhat abstract, as the level of agrochemical residues on crops is already very low, the benefits to farmers include higher profitability as a result of reduced chemical input and reduced toxic exposure. For example, farmers in some nations experienced a 75% reduction in exposure to the toxic effects of agrochemicals when growing transgenic cotton (46). Reductions in chemical exposure are clearly beneficial to the farmer, farm workers, and wildlife. 

Farmer Farm Family Exposure. Last year, the U. S. Environmental Protection Agency warned women of childbearing age to avoid farm fields recently treated with the herbicide dinoseb because the chemical might cause birth defects. Another study, conducted by a team of medical scientists, found that Kansas farmers exposed to a widely-used corn and wheat herbicide for 20 days or more a year had a sixfold increase in a certain kind of lymph cancers compared to non-farmers. And a third study from Wisconsin noted possible immune-system suppression due to aldicarb exposure. 

Because the farm enterprise will require more technical service, it is reasonable to assume that our sales representatives will become more technically oriented in order to provide farmers, farm managers, and distributors the technical information required. They will have to be crop specialists because they will be selling crop programs, not just products. Support of these personnel and services will require more sophisticated educational and communication techniques to insure effective and safe use of pesticides. 

Where possible, survey results were compared to similar data for all farmers/farms (including conventional and organic farmers/farms) in South Africa. This reference data was obtained from the Abstracts of Agricultural Statistics (Abstract, 2001), an extensive study of the Buro vir Markte en Media (1997) and Van der Westhuizen and Viljoen (1999). The latter was used, although not representative for South African farmers, since no recent data were available from the Statistics South Africa. The most recent data from the Agricultural Census dated back to the 1980s and was thus not expedient. It is therefore limited in its representativeness for the whole of South Africa.

Transportation and Distribution Cost. Although much ammonia serves as feedstock for other processes, the largest single use in the United States is as a direct appHcation fertiliser without further processing. This direct appHcation consumption is mosdy in the farm belt and ammonia produced in the Gulf Coast states is shipped to terminal faciUties and then distributed by retail outlets to the farmer.

When the trial site is not on a special research facility, the evaluation and selection of held investigators (farmers) may be difficult. The best trial results are normally obtained from those trials conducted on farms where the farmers or techni-cians/agronomists involved with the normal application of pesticides on the farm are involved in the conduct of the trial, and are aware of the objectives so that they avoid treating the trial area with products likely to interfere with the analysis. 

One of the most important aspects of designing a successful worker exposure or re-entry study is the selection of the agricultural site at which to perform the study. One must first define the growing region in which the pesticide is to be used to the widest extent possible. This is important since this region would have the most farms, farmers, commercial applicators, or re-entry workers which would have work habits, equipment, and land, which would best represent the use of the product. 

Major registrants typically conduct as many residue trials as possible on their own research farms and contract the remainder to independent contract research companies. These contract research companies range in size from those that have several research farms to husband and wife teams with only one site. They also may include independent researchers who do not own a permanent test site but contract small plot test areas from farmers inside commercial production acreage. The goal of these trials is to conduct the smdy in a cropping system environment that represents commercial production systems, thereby ensuring that the raw agriculture commodities harvested represent commercially available commodities. 

One purpose of this book is to help the organic farmer define how much milk or meat or cereal he can produce from clay or chalk land, and how this will vary according to temperature, rainfall and altitude. Farmers like to do better than their neighbours, or at least as well, producing more bales of hay per ha for example. But, particularly with organic farming, this is likely to be the case only if the... 

The monitoring of organic farms in Europe and North America is relatively well-established. However, as Herrmann and Heid (2000) pointed out, several European member states are voicing doubts about the reliability of control mechanisms among groups of small farmers in Latin America, Africa and Asia. 

Similar findings on dairy farms in Canada were reported by Stonehouse, et al. (2001). The superior economic performance on organic dairy farms was attributed to lower costs of production for almost all material inputs, including dairy herd replacements and livestock feeds. The organic dairy farmers used more land for feed crop production for the dairy cows in order to be as self-sufficient as possible. The conventional dairy farmers imported crop seeds, synthetic chemical fertilisers and pesticides, feedstuffs and herd replacements, with more of their land being devoted to cash crops.
