Manure management in dairy herds and perception of its emissions and interest in developing organic fertilizers

Abstract

The manure generated in dairy farms can cause negative environmental impacts if not properly managed, as its components are potential producers of greenhouse gases. The objective was to evaluate manure management on dairy farms and understand producers' perceptions regarding emissions and their interest in producing organic fertilizers. A descriptive study was conducted through a questionnaire administered to livestock producers to gather data on their manure management practices and appreciate their perceptions. It was found that generally, manure is collected daily, stored outdoors, and treated through solarization; it is primarily used for corn planting and maintaining cultivated pastures as it improves soil texture and helps retain moisture. Regarding perceptions, very few acknowledge that manure emits greenhouse gases; however, there is agreement on implementing good management practices to reduce emissions, as many rate their manure management on their properties as poor to fair, and most producers are interested in learning to produce organic fertilizers. The current manure management practices are contributing to greenhouse gas emissions, and through training programs and technical assistance, proper management should be promoted using efficient storage and treatment methods.
