“…The great importance attributed by farmers to TN content could be due to a lack of knowledge regarding the compost nutrient contents in general [52]. As confirmed by many authors [53][54][55], compost should be considered as an organic amendment affecting several soil characteristics.…”

Reuse of Animal Manure: A Case Study on Stakeholders’ Perceptions about Pelletized Compost in Northwestern Italy

2018

Abstract:The present study aimed at investigating perceptions and preferences about the use and the chemical characteristics of pellets made from composted animal manure in a sample of Italian farmers and agricultural advisors (Piedmont region, Northwestern Italy). The study encompassed two different steps: At first, the participants were administered a questionnaire about their actual use of pellets and preferences about their chemical characteristics. Then, a subgroup participated into a hands-on experience with different pelletized animal manures and some final questions. Concerning the use of pellets made from composted animal manure, even if the participants affirmed to be interested in using organic pellets and declared to own the appropriate equipment needed for their application, the results indicated that pelletized compost utilization had not yet become a common practice for agricultural crops. The obtained results highlighted a lack of knowledge, especially among farmers, about the importance of some chemical properties of this pelletized organic material. The participants, both farmers and advisors, were particularly attracted by the total nitrogen content of organic pelletized fertilizers, probably because the supplying of nutrients, nitrogen particularly, is the function of fertilizers they were interested in the most due to its direct connection with crop production. The hands-on session allowed the participants to better understand the benefits of the principal chemical properties-organic matter and carbon to nitrogen ratio-of pelletized animal manure compost. On the other hand, organic matter content and carbon to nitrogen ratio, more related with biological fertility and biodiversity of soils, are immediately less interesting and, as the hands-on experience pointed out, require more effort to be appreciated by agricultural operators. Targeted information campaigns and training activities may be developed among the agricultural community to make them aware of the importance of increasing soil organic matter content, and the possible use of pelletized composted animal manure. Further studies should be addressed toward gaining more insights into the beneficial effects of the information and training activities for pelletized compost adoption.

“…In Denmark, the barriers selected by farmers in terms of manure use as organic fertilizer were evaluated by Case et al (2017). The most important problems were odor nuisance, unreliable nutrient content, difficult planning, expensive machinery, and the absence of a quality certification.…”

“…Similar studies have been carried out by Blok et al (2015), who stated that this methodology allows a better understanding of the needs and perceptions of stakeholders, facilitating successful innovations for sustainable production and consumption. In a study in Denmark, Case et al (2017) assessed the impacts of new legislative requirements for the processing of organic waste through the evaluation of the perception of producers toward the use of organic waste, while Hou et al (2018) focused on how manure management is likely to be affected by a wide range of diverse socio-political and environmental factors.…”

“…The second section addressed an option that allowed the respondents to choose whether manure or slurry should be reused as fertilizer. There were also five options in terms of "needs" and five in terms of "barriers, " and the respondents could choose one or multiple answers (Bernal, 2017;Case et al, 2017;Hou et al, 2018). The response options were selected based upon previous studies and tested by experts in the field of manure management (Salazar et al, 2007(Salazar et al, , 2010Asai et al, 2014;Palhares, 2014;Vankeirsbilck et al, 2016;Charlón et al, 2017b;Palhares et al, 2017).…”

“…This situation was an incentive for the evaluation of the perception of producers toward the use of organic waste (Case et al, 2017). It is important to carry out studies to understand the decisions of farmers, professional consultants, and policy makers regarding the adoption of alternative organic crop fertilizers, especially against the background of no regulatory incentives or no history of using these techniques.…”

Milk production is important in South American countries being based mainly on grazing systems. Dairy slurry management has become an important issue in these production systems because of the large volumes produced and the environmental effects. Thus, manure management regulations are emerging in the region. This research aims to identify priorities for management strategies and technology transfer by assessing perceptions, needs and barriers toward dairy manure management by stakeholders in South American countries. A questionnaire was prepared and distributed in Spanish and Portuguese in different formats: on paper and online (PDF format and SurveyMonkey TM platform) between March 2015-November 2017. It was divided into two sections, the first addressed issues related to water quality and pollution, odor generation, fertilizer value, pathogens impact and biogas production. Responses were measured across a standard 5-point Likert type scales. Section two addressed needs and hindrances concerning about manure application. A total of 593 surveys were completed: Argentina (n = 308, 52%), Brazil (n = 217, 37%) and Chile (n = 68, 11%). The majority of respondents were dairy farmers (31%), professional advisors and consultants (29%) and representatives of public institutions and researchers (31%). Some differences appear according the country. Overall, a large majority perceive that manure is a good fertilizer (91%), also they believe that it contributes to pathogen's transmission and groundwater and shallow aquifers 'contamination. Stakeholders (60%) perceived biogas production as a good option for manure treatment. Most of respondents (79%) would use manure to replace mineral fertilizers, with little differences between countries (Argentina 79%, Brazil 80% and Chile 68%). The most selected needs were: a management handbook, increased investment in equipment and technologies and better access to laboratory analysis. The most chosen barriers were: cumbersome management, lack of knowledge and of specific laws, with differences between countries and respondents. The survey showed interest in dairy manure management as a source of nutrients for grassland and crops, especially among farmers and advisors whom requested Herrero et al.South American Dairy Manure Management Perceptions guidelines for responsible management. Policymakers and stakeholders should focus on promoting manure reuse on dairy farms through incentives, technologies and/or appropriate strategies, in order to improve nutrient use and reduce pollution to the wider environment.
