Organic Liquid Manures and Bio-Fertilizers: A Tool for Soil and Crop Productivity

Organic farming is an internationally regulated, legally enforced and standardized alternative agricultural paradigm that relies on ecological processes, biodiversity and cycles adapted to local conditions with the aim of sustaining the health of soils, ecosystems and people. Organic farming utilizes various naturally obtaining substances such as manures, bio-fertilizers. Widely recognized among them are manures and bio-fertilizers. Conventionally they are applied as a solid and carrier based, but modern approach of applying in liquid form is gaining reputation. Application in liquid form facilitates better release of nutrients, enhancement of soil microbial activity, improvement of soil aggregation, soil properties and soil health. Some of the famous liquid manures are jeevamruth, panchagavya, beejamruth, vermiwash, humic acid and sea weed extract. Based on these evidences this paper explores the effectiveness, importance and limitations of most commonly used organic liquid manures. This paper also explains about the usage of liquid bio-fertilizers and their advantages.
