Bio-enhancers: a potential tool to improve soil fertility, plant health in organic production of horticultural crops.

摘要: Indiscriminate use of agro-chemicals during the last 5–6 decades has adversely affected soil fertility, crop productivity, produce quality and particularly environment. Annually India is loosing nearly 0.8 million tones nitrogen, 1.8 millions Phosphorus 26.3 potassium (Annonymous, 2011). Soil organic carbon content in most Indian soils been reduced to > 0.5 per cent. The green revolution exhibiting second generation problem owing over exploitation mis management soil. Under these circumstances, maintenance fertility productivity are major constraints agriculture. Excessive mining micronutrients have led deficiency micro nutrients one or other parts country. As a result fertigation becoming popular part states. It pertinent pinpoint that at present, soluble fertilizers imported country very expensive, beyond reach common farmers. For number nutrients, not available. Hence, this requires change mind set for addressing issue. After closely working with Organic Farming Systems decade, we view “Bio enhancers” could be cheap alternative tool resolve many issues including effective fertigation. In production systems, there always challenge how improve pests by techniques. Use liquid preparations an age old practice India. On farm produced Kunapajala, prepared fermenting animal flesh along herbal products used established technique ancient alternative, farmers devised boosters based on local experiences gave specific names such as Amritpani, Panchagavya, Beejamrita, Jiwamrita etc. Similarly, farming few BD-500, BD-501, Cow Pat Pit, Biodynamic manures Homa Farming: Agnihotra ash enriched water Biosol tools being organizations. interesting note all preparations, basic ingredients cow products. order give generic name, hence forth, named enhancer” which almost new world scientific community. Review available literature bio enhancer indicates immense scope its promotion tried review information objectives communicate community initiate systematic research, extension agencies promote alternatives agro chemicals prepare their own utilize them requirement.
