Brazilian consumers’ perception of edible insects Ciência Rural
Schardong,Igor Sulzbacher; Freiberg,Joice Aline; Santana,Natielo Almeida; Richards,Neila Silvia Pereira dos Santos.
ABSTRACT: It is estimated that by 2050 the world population will be 9 billion people; and therefore, the need for alternative sources of protein is inevitable, since conventional sources, such as beef, pork and poultry, will not be sufficient to meet the demand of population growth. Food that includes alternative sources of protein, such as insects, is a reality in countries of Latin America, Asia, Australia, Europe and Africa. This research presents the results of an exploratory study that analysed the food profile of 1,619 consumers in the five Brazilian regions (North, Northeast, Midwest, Southeast and South) as well as their perception, motivation and preferred form of edible insects. The data were analysed by cross-tabulation and expressed as...

Cattle Manure Bioconversion Effect on the Availability of Nitrogen, Phosphorus, and Potassium in Soil Rev. Bras. Ciênc. Solo
Eckhardt,Daniel Pazzini; Redin,Marciel; Santana,Natielo Almeida; Conti,Lessandro De; Dominguez,Jorge; Jacques,Rodrigo Josemar Seminoti; Antoniolli,Zaida Inês.
ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: soil without fertilizer (control); soil + beef cattle manure vermicompost; soil + beef cattle manure/straw compost; soil + beef cattle manure; soil + dairy cattle manure; and soil + vermicompost produced...

Differential behavior of the summer cover crops in the absorption and translocation of copper Ciência Rural
Vendruscolo,Diogo; Santana,Natielo Almeida; Souto,Kelen Müller; Ferreira,Paulo Ademar Avelar; Melo,George Wellington Bastos de; Jacques,Rodrigo Josemar Seminoti.
ABSTRACT: Phytoremediation is an alternative technique used to treat copper-contaminated soils. The objective of this research was to explore the behavior of nine summer cover crops regarding the growth, absorption and translocation of copper in soils with contamination levels exceeding the Value of Prevention, with a view to selecting plants for phytoremediation programs. In the experiments the Cambisol was contaminated with copper, added in doses of 0, 100, 200, 400, 500 and 600mg kg-1, in which the following nine plants were cultivated under greenhouse conditions: Canavalia ensiformis, Cajanus cajan, Dolichos lablad, Mucuna cinereum, Mucuna aterrima, Crotalaria juncea, Crotalaria spectabilis, Pennisetum glaucum and Paspalum notatum. At 90 days after...

Effects of pig slurry application on the diversity and activity of soil biota in pasture areas Ciência Rural
Silva,Danni Maisa da; Jacques,Rodrigo Josemar Seminoti; Silva,Diego Armando Amaro da; Santana,Natielo Almeida; Vogelmann,Eduardo; Eckhardt,Daniel Pazzini; Antoniolli,Zaida Inês.
ABSTRACT: The successive application of pig slurry to pastures is a common practice in southern Brazil, serving as a method of waste disposal as well as an important alternative to chemical fertilization. Although there are economic benefits to the use of manure as fertilizer, it may be associated with environmental hazards and cause changes to composition and activity of soil fauna. This study aimed to study the effects of pig slurry on the soil biota of pastures. Composition and biological activity of pastures where manure was applied successively for 2 years (A2) and 14 years (A14) were evaluated, and native forest (NF) was analyzed as a reference area. Successive application of pig slurry to the soil changed its biological characteristics according to...

Soil Biological, Chemical, and Physical Properties After a Wildfire Event in a Eucalyptus Forest in the Pampa Biome Rev. Bras. Ciênc. Solo
Santana,Natielo Almeida; Morales,Cedinara Arruda Santana; Silva,Diego Armando Amaro da; Antoniolli,Zaida Inês; Jacques,Rodrigo Josemar Seminoti.
ABSTRACT Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed to assess the effect of a wildfire event on chemical, physical, and biological properties of the soil in a eucalyptus forest in the Pampa biome. Part of a seven-year-old eucalyptus forest was affected by a wildfire event that lasted for two days. Soil and plant litter sampling was performed in three areas: in the forest that was not affected by the fire, in the forest affected by it, and in an adjacent natural pasture area (the original vegetation). Seven samples were collected from the 0.00-0.05 and 0.05-0.20 m layers of each plot for biological analysis, and three samples were collected for chemical...
