conventional farming efficiency

Crop rotation, along with natural fertilization, allows farmers to often harvest generous crops from healthy soil. Seed treatment is clearly the most targeted application for fungicides against seedborne diseases such as bunts, smuts, leaf stripe of barley, seedling damping-off diseases, Fusarium spp., and many others. For this reason, soil and seed treatment applications of fungicides against foliar diseases have been discouraged by the Fungicide Resistance Action Committee (FRAC, Most organic poultry production is currently based on the same breeding stock as conventional farming and the principal problems (see above) are the same. A search for alternative breeds/hybrids has not yet produced the ideal ‘organic hen’. A higher soil water content in conservation agriculture can buffer for short drought periods during the growing season. This will have to change in the future, especially with regard to our diminishing reserves of phosphorus that’s currently being wasted to sewage! Manure and compost are regularly used in both organic and conventional farming as a soil amendment to provide vital minerals and organic matter aiding in soil structure and plant growth. Birds should be able to cope with different feed compositions. In addition, adoption of no till or minimal till in organic farming systems can lead to increased retention of SOM (Six et al., 2002), and increased bacterial and faunal diversity.

Therefore, all of our organic waste should be collected seperately and composted. Soil and soil amendments are necessary for most farm operations, however inattention to the quality of material going into the system can pose a food safety risk.

Examples of tolerance to important crop pathogens achieved by GM have been few, however, and, to the author′s current knowledge, except for control of papaya ring spot virus of papaya in Hawaii and watermelon mosaic virus of cucurbits in the eastern USA, none have been commercially introduced. There may, however, be some limitation of this technology, for example, in the requirement for quite high water volumes to ensure distribution of some fungicides, or the potential for spray drift; and it may not be the most appropriate time in the life cycle of the pathogen to target. (2017) clearly demonstrated that some of bacterial phyla (i.e., Firmicutes, Actinobacteria, Chloroflexi, Verrucomicrobia, Armatimonadetes, Crenarchaeota) are independent on farming system and its abundance remains similar both in conventional as organic system. Manure from extensive conventional farms can be used; manure from intensive livestock units or from farms growing genetically modified crops is forbidden (EC,1991, 2092/91). Examples of such diseases include downy mildews of corn and peas (Perenosclerospora spp. Birds should show resistance to diseases and parasites, even if selecting for a certain trait means poorer performance in another area. The discussion group agreed that poultry breeds and breeding programmes for organic farming should have the following characteristics (Hirt et al., 2001): The animals should show normal social behaviour in large groups (no or low levels of feather pecking and cannibalism). So the choice of strain is for marketing/consumers, not for the layers welfare! Excess water can be removed from the root zone by lowering the water tables with drainage. Ideally, the difference between input and output would be zero: you take as much nitrogen away from the field as you previously put in, making sure that nothing is wasted and nothing is washed out into the groundwater. U.S. consumers have come to expect abundant and inexpensive food. Lupatini et al. These treatments can be either passive or active, ranging from the least labor intensive processes of “aging,” where manure piles are simply stored before use, to more intensive treatment involving physical or microbial activity: pasteurization, aerobic digestion, or composting (FDA, 1998). Moreover, there is growing worldwide concern regarding the emission of greenhouse gases and their effect on our climate, which is directly related to the use of fossil energy. Finally, we can use output/input ratios to compare the efficiency of animal farming with that of … Table III. Helen Hirt, Esther Zeltner, in Handbook of Organic Food Safety and Quality, 2007. and soilborne Phytophthora spp. a) Leftovers from the food we bought (such as peels, leaves, fruit stones etc.) This manifests itself in an excessive tendency for feather pecking and cannibalism, and, independent of flock size, many mislaid eggs. Muscle diseases and breast blisters may affect slaughter performance negatively. There is therefore a need for ‘robust’ slower growing breeds that are flexible and can adapt to a wider range of husbandry and feeding conditions (Hirt et al., 2001). Cereal yields in organic production are typically 60–70% of those under conventional management although vegetable yields are often just as high as under conventional management (Offermann and Nieberg, 2000). Apart from monitoring soil amendment application, farmers should also scrutinize the layout of the farm operation such that there are sufficient barriers between raw manure and finished compost piles, crop production areas, and wildlife habitats to minimize dissemination of pathogens by rainfall, leachate, or intrusion. Interestingly remains the fact reported by Birkhofer et al. Conventional Farming: Resource Efficiency … Also observed is a widening disparity among the income of farmers and the escalating concentration of agribusiness—industries involved with manufacture, processing, and distribution of farm products—into fewer and fewer hands. In that context, the fact that considerably interferes the soil biological balance becomes of secondary importance (Gomiero et al., 2011; Pershina et al., 2015). According to them organic farming used only about a third of the energy per unit area of land than conventional farming did. What’s missing, even in organic farming? It is probable that even if disease tolerance becomes successfully implemented in major economic crops such as cereals, potatoes, or soybeans, these traits will themselves require protection through the integrated approach of using chemical fungicides in programs to manage the diseases and avoid the tolerance breaking down. Both positive and negative consequences have come with the bounty associated with industrial farming. Despite the availability of improved crop varieties with increased yield potential, the optimum production is not attained generally because of poor crop management (Reynolds and Tuberosa, 2008). Only through creative and informed use of the different characteristics of catch crops and green manures, can stockless systems ensure their sustainability. This is due to the marketing facts: the consumer learns that brown eggs are laid in animal-friendly strawyard systems, and that white eggs come from battery cages! Comparing Organic vs. Some success has also been achieved with the resistance-inducing compounds such as acibenzolar-S-methyl, which are able to activate the plant′s natural defense mechanisms including those against fungal and bacterial plant pathogens. Another fertilizer that conventional farming depends on is phosphorus, an essential element for growing plants.
