3. USE OF INOCULUM IN BIODIGESTERS WITH CATTLE MANURE UNDER CONVENTIONAL AND ORGANIC PRODUCTION SYSTEMS
ABSTRACT One way of making livestock farming a more sustainable practice is to raise cattle organically. However, regardless of the production system, there is a generation of residues that can be converted into energy resources using biodigesters. This study aimed to evaluate the addition of inoculum in the anaerobic biodigestion of cattle manure under orga

4. PAPAYA SEEDLING PRODUCTION UNDER DIFFERENT SHADING LEVELS AND SUBSTRATE COMPOSITIONS
ABSTRACT Papaya is characterized as one of the most important crops in Brazil. Thus, good quality seedlings are essential for formation of orchards in agricultural production. This study aimed to evaluate shading levels and substrate compositions for production of papaya seedlings. Growing environments were evaluated with 0, 18, 35, and 50% shading and subst

6. Utilization of bedded cattle confinement for organic manure of maize crop
RESUMO O uso de resíduos orgânicos, provenientes de sistema de confinamento no modelo ‘Compost Barn’ poderá suprir grande parte da demanda por adubo na propriedade. Além disso, com o aumento do consumo de alimentos oriundos da pecuária sustentável, a utilização de adubo gerado na própria propriedade se torna economicamente viável. Este trabalho

8. Ammonia Volatilization from Soil-Applied Organic Fertilizers
ABSTRACT: A reliable quantification of nitrogen (N) losses by ammonia (NH3) volatilization can contribute to identifying optimized strategies of fertilizer management. The objective of this study was to quantify ammonia volatilization from several organic N sources incorporated into or applied onto the soil surface. Two cultivation areas, under snap bean and

9. Humic Substances and Chemical Properties of an Acrisol Amended with Vermicomposted Vegetal and Animal Residues
ABSTRACT Vermicomposted vegetal and animal residues are rich in nutrients and humic substances and thus can be applied to the soil as a source of functionalized organic matter (OM) and as an alternative to chemical fertilizers. In Southern Brazil, many animal and vegetal residues are easily accessible. Therefore, this study aimed to evaluate alterations in s

12. Organic Fertilizer for Production of Toona ciliata Seedlings
ABSTRACT This study evaluated the effect of different sources of organic fertilizer and their most appropriate proportions to produce Toona ciliata seedlings. Broiler litter and cattle manure were used as organic fertilizer at four proportions in the substrate (0, 15, 30, and 45%). A control treatment was adopted with 6 kg controlled-release fertilizers (m-
