Precompression stress and compression index depend on the property used to represent the soil deformation in the compression curve

Autor: Paulo Ivonir Gubiani, Quirijn de Jong Van Lier, José Miguel Reichert, Rafael Ziani Goulart, Eracilda Fontanela

Publikováno v: Ciência Rural, Vol 46, Iss 1, Pp 76-82 (2016)

ABSTRACT: During linear deformation (h) in a soil sample, the variation of the void ratio with respect to deformation (dε/dh) and the respective variation of soil bulk density (dρ/dh) are identical only for a specific value of h. Consequently, if t

Crescimento e produção de milho associados com o intervalo hídrico ótimo

Autor: Paulo Ivonir Gubiani, Rafael Ziani Goulart, José Miguel Reichert, Dalvan José Reinert

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 37, Iss 6, Pp 1502-1511 (2013)

O Intervalo hídrico ótimo (IHO) é muito utilizado como indicador agronômico de qualidade física do solo, contudo pouquíssimas pesquisas relacionaram o IHO com crescimento e produção de plantas. Os escassos resultados são insuficientes para c

Produtividade, qualidade dos frutos e distribuição do sistema radicular da melancia em diferentes sistemas de cultivo

Autor: Marta Rodrigues da Rocha, Flávio Luiz Foletto Eltz, Michele Silva dos Santos, Pedro Vanti da Rocha, Rafael Ziani Goulart

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 35, Iss 4, Pp 1377-1386 (2011)

A melancia é cultivada principalmente por pequenos produtores, em solos arenosos sob preparo convencional, com ocorrência de altas taxas de erosão, já que a cultura não forma dossel vegetativo capaz de cobrir inteiramente o solo. Com o objetivo

Different water management strategies should be investigated to ensure adequate water supply to furrow-irrigated soybean plants in lowlands. This study examined the performance and efficiency of furrow irrigation techniques and related them to the so

Comparing tillage methods for growing lowland soybean and corn during wetter-than-normal cropping seasons

Autor: José Miguel Reichert, Miriam Fernanda Rodrigues, Éderson Diniz Ebling, Rafael Ziani Goulart, Miguel Chaiben Neto

Publikováno v: Paddy and Water Environment.

Rice monocropping underutilizes the productive potential of lowland soils. A major challenge in cropping low-drainage soils, particularly in wetter-than-normal years, is improving drainage conditions of paddy soils to allow rotation with upland crops

Cropping poorly-drained lowland soils: Alternatives to rice monoculture, their challenges and management strategies

Autor: Miriam Fernanda Rodrigues, José Miguel Reichert, Rafael Ziani Goulart

Publikováno v: Agricultural Systems. 177:102715

Lowland areas consist mostly of hydromorphic, poorly-drained soils, constituting an important agricultural frontier in Brazil and around the world. Flood-irrigated rice cultivation has become a monoculture in lowland soils, degrading soil structure a

Furrow Irrigation for Corn Cultivation in Hydromorphic Soils

Autor: Silvana Antunes Rodrigues, Vinício José Bordignon, Jhosefe Bruning, Bruna Dalcin Pimenta, Miguel Chaiben Neto, Yesica Ramirez Florez, Adroaldo Dias Robaina, Elisa de Almeida Gollo, Rafael Ziani Goulart, Marcia Xavier Peiter

Publikováno v: Journal of Agricultural Science. 11:295

The use of crop rotation in hydromorphic soils has been intensified in the state of Rio Grande do Sul, Brazil. Due to the difficult management of these soils, the use of irrigation is fundamental to increase the reliability of these production ecosys
