Pesticides: perception of environmental risk and quantification of glyphosate in atmospheric deposition (Entre Ríos, Argentina)
(Ediciones INTA, 2023-09)In Argentina there has been a growing conflict about the use of pesticides and their impacts, mainly with regard to the air compartment and areas with close proximity between agricultural and residential land uses. The ... -
Plant emergence and maize (Zea mays L.) yield across multiple farmers’ fields
(Elsevier, 2023-10)Context: Uneven crop stands result from natural variation in emergence time that is related to soil moisture and temperature, and variation of within-row plant-to-plant distance caused during planting operations. Understanding ... -
Processing Pipeline of Sugarcane Spectral Response to Characterize the Fallen Plants Phenomenon
(IOP Science, 2016)Nowadays, in agronomic systems it is possible to make a variable management of inputs to improve the efficiency of agronomic industry and optimize the logistics of the harvesting process. In this way, it was proposed for ... -
Characterization of multispectral aerial images of sugarcane
(IOP Science, 2013)In this paper we present a implementation and characterization the status of sugarcane plantations based on the analysis of multispectral aerial images. Currently there are no precise techniques to estimate objectively the ... -
Gestión de cuenca: plan integral para el área de conservación de suelos de la Aldea Santa María
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Rios, 2019)La erosión hídrica constituye una de las principales limitantes de la producción agropecuaria en la Provincia de Entre Ríos.
