Organic production systems are system which promotes and enhances agroecosystem based on specific and precise standards of production health, including biodiversity, biological cycle and soil which aim at achieving optimal agro-ecosystems which biological activity, and this is accomplished by using are socially, ecologically and economically sustainable.

Organic used in an effort to describe the organic system more farming is the best choice we can make for our clearly. Requirements for organically produced foods environment, animals and our own health.

It aims to differ from those for other agricultural products in that produce food while establishing an ecological balance production procedures are an intrinsic part of the to prevent soil fertility or pest problems.

Soil building identification and labeling of, and claim for, such practices such as crop rotations, inter-cropping, products. Organic production systems avoid or symbiotic associations, cover crops, organic fertilizers minimize the use of synthetic fertilizers, pesticides and and minimum tillage are central to organic practices.

Well managed organic soil properties [2]. Organic farming practices aim to systems with better nutrient retentive abilities, greatly increase sustainability by reducing pesticide residues on reduce the risk of groundwater pollution.

Organic crops Figure 1: Organic agriculture leaching losses and runoff environmentand reducing contributes to mitigating the greenhouse effect and soil erosion by enhancing soil structure productivity, global warming through its ability to sequester carbon in environment [5].

It has to be stressed, however, that the soil. The impact of organic agriculture on natural alternative farming systems are not sustainable per resources favors interactions within the agro-ecosystem definitionem.

Incorporation of leys, legumes or animal those are vital for both agricultural production and manures, for example, can lead to a nitrate surplus and nature conservation.

Most authors have come to broadly similar conclusions, as follows: Organic agriculture, problems, prospects - There is inconsistent evidence regarding the impact of and environmental issues organic farming on soil structure.

Introduction animal or green manures, crop residuewhich is Organic agriculture is holistic production management beneficial for soil microbial biomass and activity.

Organic farmers do not use: Although nitrate losses can be increased after ploughing of ley phases and Productivity incorporation of green manure crops, it has been suggested that nitrate losses are similar from both systems when assessing the organic rotation as a whole instead of this one aspect [18].

Most of these findings are relative depending on their Environment Human health assessment on a per area unit e.

Soil quality and the three related concerns [5] diversity or organic management systems were observed when assessing the parameters per unit of Ecological dimensions yield [20].

The flow of energy that involves biological and non- There is evidence for high variability within the findings biological agents drives the carbon, oxygen, nitrogen presented above as a larger variety of different and phosphorus cycles. Nutrients are pumped through management practices are employed under the labels of the system by the action of photosynthesis and are again organic and, especially, conventional farming.

This made available for recycling by the action of makes it problematic to identify trends when comparing decomposers. Nutrients are constantly being removed or management systems and many benefits of one or the added; adding more natural substances or synthetic other system will depend on the individual farming materials than the ecosystem is able to handle upsets practices used by the farmers [7].

In addition, most of bio-geochemical cycles [12]. This causes difficulties to include extrapolate results and make statements for other areas Soil forming and conditioning: A substantial amount of the world, which means it is necessary to validate the of invertebrates earthworms, millipedes, termites, conclusions for different environments including New mites, nematodes, etc.

Overall, more information and research upper soil layers through decomposition of plant litter, are needed to resolve outstanding questions, especially making organic matter more readily available, and regarding the effects of farm management practices on creating structural conditions that allow oxygen, food biodiversity in general, the diversity of the soil and water to circulate.
