Appelhans, Stefania Carolina; Novelli, Leonardo Esteban; Melchiori, Ricardo Jose; Gutierrez Boem, Flavio Hernán; Caviglia, Octavio (Springer, 2021-05-27)Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ... -
Defoliation affects soybean yield depending on time and level of light interception reduction
Gregorutti, Viviana Carolina; Caviglia, Octavio; Saluso, Adriana (Southern Cross Publishing, 2012-07)Light interception (mainly due to defoliation) during the critical growth periods of soybean may be a suitable index for calculating the economic injury level (ELI) rather than measuring the insect population or percentage ... -
Evaluation of Agricultural Production Systems Simulator as yield predictor of Panicum virgatum and Miscanthus x giganteus in several US environments

Forage yield, water- and solar radiation-productivities of perennial pastures and annual crops sequences in the south-eastern Pampas of Argentina
Ojeda, Jonathan Jesús; Caviglia, Octavio; Agnusdei, Monica Graciela; Errecart, Pedro Manuel (Elsevier, 2018-05-15)Livestock production systems of Argentina show an ongoing process of change in the composition of their forage base, with a gradual increase in the proportion of their area assigned to forage crop sequences (FCS) −in ... -
Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms
Gregorutti, Viviana Carolina; Caviglia, Octavio (Elsevier, 2019)In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ... -

Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks
Novelli, Leonardo Esteban; Caviglia, Octavio; Piñeiro, Gervasio (Elsevier, 2017-01)Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ... -
Land use intensity and cropping sequence effects on aggregate stability and C storage in a Vertisol and a Mollisol
Novelli, Leonardo Esteban; Caviglia, Octavio; Wilson, Marcelo German; Sasal, Maria Carolina (2013)The relevant change in land use duemainly to the rapid expansion of soybean cropping towards areas traditionally occupied for livestock purposes or with native grasslands of South America may have negative consequences on ... -
