“…In the European Union, quality parameters for biofertilizers are not yet standardized and they vary from one region to another (Malusá and Vassilev, 2014). Currently, India seem to have the most standardized and functional legal framework related to biofertilizers (Malusá and Vassilev, 2014;Manashi et al, 2017). 2015, Permission acquired from the author].…”

The production of biofertilizers at industrial level is a bottleneck because bacterial strains are generally developed and managed by research laboratories and not by production units. A seamless transition from laboratory to field application is, therefore necessary. This review provides an overview of the constraints that limiting the application or the implementation of Actinobacteria based biofertilizers especially in agricultural field and suggests solutions to overcome some of these limits. General processes of making and controlling the quality of the inoculum are briefly described. In addition, the paper underlines the opportunity of biofertilizers alone or in combination with chemical fertilizers. This review also, highlights the latest studies (until June 2019) and focuses on P-solubilization microorganisms mainly Actinobacteria. The biotechnology of these bacteria is a glimmer of hope for rock phosphate (RP) bioformulation. Since direct application of RP fertilizer is not always agronomically effective due to its sparse solubility.

“…Agroecological farms also adopted other practices to maintain soil fertility, including the use of compost, biofertilisers, and agroforestry. These practices reduce the need to apply chemical fertilisers and generate other benefits for the soil, such as increased organic matter content, reduced soil erosion and improvement of soil biological and physical quality [46,47]. Alternative practices for biological control were also more common in agroecological farms, such as the use of plant extracts to manage pests and diseases, and the cultivation of repellent plants [48,49].…”

Understanding Farm Diversity to Promote Agroecological Transitions

et al. 2018

Agroecology is increasingly promoted by scientists, non-governmental organisations (NGO’s), international organisations and peasant movements as an approach to foster the transition to sustainable and equitable food systems. The challenges to agroecological transitions are not the same for all farmers, as they can face different social and bio-physical conditions. We developed a farm typology combining participatory and quantitative methodologies to assess and categorise farm diversity and its implications for developing strategies to promote agroecological transitions. The participatory typology was developed during workshops to acquire insights on local farmers’ perceptions and knowledge, and to generate hypotheses on family farm diversity. The participatory-based hypotheses were tested in the quantitative farm characterisation, which provided information on household characteristics, production strategies, land use, participation in public policies and extension services. Farms were located in Zona da Mata, Minas Gerais, Brazil, which harbour a wide diversity of farmers and where different actors have been engaged in agroecological transitions for the past 30 years. Our main findings were: (i) In the face of agroecological transitions, farmers differ in their management strategies, practices and principles; (ii) farmers identified as agroecological typically had stronger engagements in a network composed of farmers’ organisations, universities and NGO’s; (iii) agroecological farms showed great potential to provide a wide range of ecosystem services as they featured a higher crop diversity and a higher number of crops for self-consumption; (iv) to promote agroecology, it is crucial to recognise peasant knowledge, to change the dominant discourse on agriculture through social movement dynamics, and to generate support from public policies and funds; and (v) participatory and quantitative methodologies can be combined for more precise and relevant assessments of agroecological transitions.

“…Recently, biofertilizers are gaining momentum due to its ability to maintain soil health, minimize environmental degradation, and cut down the use of inorganic fertilizers in agriculture. These inputs gained added importance in rainfed agriculture in view of their low cost, as small to marginal farmers across the globe cannot afford expensive chemical fertilizers [4]. Biofertilizers could be an ideal input for cutting the cost of production and for practicing organic and conservation farming [5].…”

At present time, chemical fertilizers are more in practice for crop production, which failed to upkeep soil and environment quality and affected the sustainability of the agricultural production system. Conversely, biofertilizers are ecosystem friendly, one of the best modern tools for agriculture, and are used to improve soil fertility and quality. Biofertilizers have now emerged as a highly potent alternative to inorganic fertilizers and offer an ecologically sound and economically attractive route for augmenting nutrient supply and increasing crop production. These include live cells of diverse genera of microorganisms and have the potential to fix atmospheric nitrogen and solubilize and mobilize plant nutrients from insoluble form through microbiological process. It has also the potential to diminish the gap between nutrient supply through fertilizers and nutrient removal by crops. Hence, biofertilizers can be a feasible option to the farmers to increase crop productivity and should find greater acceptance from the extension workers and commercial biofertilizer manufacturers.

The nitrogen-fixing bacteria work under two conditions, symbiotically (Rhizobium, Frankia) and as free-living bacteria (nonsymbiotic) such as Azotobacter and Azospirillum. The N 2 -fixing bacteria associated with nonlegumes include species of Achromobacter, The most exploited symbiotic N 2 -fixing bacteria are those belonging to the family Rhizobiaceae. Rhizobium inoculants are of greatest importance because of their ability to fix atmospheric N 2 in association with certain legumes [11]. It is estimated that N 2 fixation by Rhizobium in root nodules of legumes is of the order of 14 million tons on a global scale and is almost 15% of the industrial N fixation. Yield of many legumes can be increased substantially by the use of appropriate Rhizobium cultures. For successful nodulation each legume requires a specific species of Rhizobium to form effective nodules. Many legumes may be modulated by diverse strains of rhizobia, but growth is enhanced only when nodules are produced by effective strains of rhizobia [12]. Rhizobium can be used for legumes crop and trees (e.g., lucerne) and is a crop-specific inoculant, for example, Rhizobium trifolii for berseem, Rhizobium meliloti for lucerne, Rhizobium phaseoli for green gram and black gram, Rhizobium japonicum for soya bean, Rhizobium leguminosarum for pea and lentil, Rhizobium lupini for chickpea, and Rhizobium spp. for cowpea. Rhizobium is however limited by cross-inoculation group, and only certain legumes are benefited by this symbiosis.Similar to the Rhizobium, other filamentous bacteria of genus Frankia belonging to the family Frankiaceae are found in the root nodules of nonlegumes such as trees and shrubs. These bacteria live in symbiosis with actinorhizal plants. These actinorhiza...
