“…This food product can be an alternative for modern life to change food pattern from chemical substance into organic one to decrease its negative impact caused by chemical substance. In organic agriculture nutrients returned to the soil in manures and composts have to be cycled via the biological life of the soil before they become available to crops (Hodges, 1981).…”

Two field experiments were carried out in clay soil at the experimental farm of Gemmeiza Agriculture Research Station (Middle Delta, Egypt). during the two successive winter seasons of March 2007 and March 2008, to investigate the possibility of spraying compost extract and humic substances as foliar appliocation for maximizing the soil compost addition. For that purpose, kidney bean (Phaseolus vulgaris, L.) was planted in two successive seasons. The compost was added to all treatments except the control (100% mineral nitrogen fertilizer). Both compost extract and humic substances were added each alone twice or alternatively. The results clearly showed a positive effect of compost extract and humic substances on all plant growth parameters. The superior treatment was when compost extract was sprayed alternatively with humic in present of 75% of mineral nitrogen fertilizer with 10 Ton/fed of compost as soil addition, the following treatment was spraying of compost extract alone with 75% of mineral nitrogen fertilizer plus (10 Ton/fed) of compost addition. Generally, results pointed that usage of compost extract and humic as foliar application maximized the utilization of soil compost addition.

“…15 For many years, one of the principal objectives of agricultural research has been to obtain maximum production, with yield tending to take precedence over quality. 16 Yields have been increased by the application of the four most important nutrient elements (nitrogen, phosphorus, potassium and calcium), usually in relatively heavy concentrations.…”

“…Most of these are not provided by modern chemical agricultural methods, and there is thus a tendency for soil nutrient deficiencies to develop and increase, affecting the availability of essential nutrients to plants and animals throughout the food chain. 15 The increase in concentration of nitrate that occurs in crops grown with chemicals also creates physiological problems for the plants. 17 The extra nitrate uptake by the cells creates a high osmotic pressure, which can only be neutralised by an increased water intake to dilute the internal environment, thus reducing the relative concentrations of plant nutrients.…”

The Prevention of Neural Tube Defects: A Public Health Approach

The recent media debate about the MRC trial of vitamin supplementation to prevent neural tube defects has tended to draw attention away from the underlying problem of inadequate micronutrient intake in the diet. From a public health perspective a broader approach must be adopted if we wish to significantly reduce the incidence of neural tube defects in the population. The prescription of vitamins can only be considered as a short-term, partial solution, and the long-term goal must be the elimination of the primary causes of micronutrient deficiencies. Particular emphasis must be placed on the nutrient losses and imbalances that arise from current food production and processing techniques.

“…Although the productivity of land has increased in the short term, concern exists that modern agriculture may not be sustainable in the long term. Central to this concern are such phenomena as pest resistance to pesticides (see, for example, Debach 1974) and soil degradation through erosion, acidity, salinity and compaction (see, for example, Department of Environment, Housing and Community Development 1978;Hodges 198 1;Hodges and Arden-Clarke 1986). Some of the unwanted effects of conventional farming occur on-farm.…”

Towards a Comparison of Chemical‐free and Conventional Farming in Australia

The classes of benefits and costs, private and external, arising from a partial movement from conventional to chemical-free farming are considered. A report is provided on a comparison of physical and financial characteristics of chemical-free and conventional cereal/livestock farming in south-eastern Australia. A key finding is that private net returns were similar for the two types of farmers. A favourable change in net externalities could be expected from a movement towards chemical-free farming. Policy implications relating to the taxation of chemical use in agriculture, and to research, extension and marketing are discussed.
