EFFECT OF THE DISTANCE BETWEEN THE CUTTING DISC AND FURROW OPENERS EMPLOYED IN ROW CROP PLANTING ON SOIL MOBILIZATION
Provedor de dados: Engenharia Agrícola
Autores: Francetto,Tiago R.; Alonço,Airton dos S.; Becker,Rafael S.; Scherer,Vitor P.; Bellé,Mateus P.
ABSTRACT The objective of this study was to determine the effect of the longitudinal distance between a cutting disc and a fertilizer furrow opener on the operational performance of the furrow opener working at different forward speeds during soil mobilization. The soil in the experimental area was classified as Typic Hapludalf with a loam soil texture. The experiment involved 24 treatment combinations in a 2 × 3 × 4 factorial scheme. These combinations were formed by the interaction of the following factors: furrow opening mechanisms, longitudinal distance from the center of the cutting mechanism to center of the furrow opener, and forward speeds. The effects of the tools on the soil mobilization variables were characterized in three phases: analysis of...

Composition and diversity of bees (Hymenoptera) attracted by Moericke traps in an agricultural area in Rio Claro, state of São Paulo, Brasil
Provedor de dados: Iheringia Série Zoologia
Autores: Souza,Luceli de; Campos,Maria J. de O.
The composition and diversity of bees in an agricultural area in Rio Claro, state of São Paulo, Brazil, were studied from May 2003 to June 2004, using Moericke traps. The collection site, an area with 58.08 hectares, is characterized by grain production and direct planting, with 70% of the surrounding area planted with sugar cane. During the study, 456 bees were collected, distributed among 20 genera, pertaining to the families Andrenidae (4.8%), Apidae (40.8%) and Halictidae (54.4%). Specimens of genera Dialictus (38%) and Diadasia (30%) predominated in this area. The species diversity, assessed using the Shannon and Simpson indices, were H’=1.88 and 1/ D= 4.15, respectively, and the Evenness index was 0.61.

Population fluctuation in soil meso- and macrofauna by the successive application of pig slurry
Provedor de dados: Revista Ciência Agronômica (RCA)

ABSTRACT Pig farming has increased in recent years, resulting in the production of a large quantity of liquid manure, which can be used as a source of organic fertiliser. The aim of this work was to determine the influence of pig slurry on the community of soil fauna in a system of direct seeding. The study was carried out in an experimental area in the town of Taquaruçu do Sul, in the state of Rio Grande do Sul, Brazil. The experimental design was of randomised blocks in a (4 + 1) x 4 factorial scheme, comprising five fertilisation treatments, 0 (no fertiliser), 20, 40 and 80 m3 of pig slurry ha-1 and one additional treatment (mineral fertiliser), with four evaluations corresponding to the number of slurry application (1st, 2nd, 3rd and 4th application),...
