Soil fertility is typically assessed by chemical analysis, which is expensive and time-consuming, and hence impractical for site-specific fertilizer management. Visible and near infrared (Vis–NIR) spectroscopy has been used for determining soil properties and chemically extractable plant nutrients. However, the suitability of Vis–NIR for...

A portable near infrared spectroscopy (NIRS) instrument was evaluated for the discrimination of individual Iberian pig carcasses into the four official quality categories (defined by a combination of genotype and feeding regime). Spectra were obtained scanning four anatomical locations (live animal skin, carcass surface, fresh meat and...

Este trabajo presenta el manejo básico de un prototipo acuapónico así como resultados preliminares sobre el crecimiento de tencas y lechugas en dicho prototipo. El sistema consta de una instalación de recirculación de agua con cuatro elementos en el siguiente orden de dirección del agua: depósito de peces, del que parten dos ramas: una de ellas...

Aquaponics involves the simultaneous production of plants and fish and it is increasingly being used with a self-consumption purpose. However, there are uncertainties and little information about the economic sustainability of small-scale self-managed aquaponic systems. The objective of this study was to obtain economic information about these...

Aquaponics is emerging as an interesting alternative for sustainable agriculture which meets the philosophy of circular economy, decreasing not only the need of external resources but also increasing their use efficiency. Several studies can be found dealing with the analysis of different fish species combined with a great variety of crops in...

Aquaponics is a developing technique that combines the simultaneous production of plants (hydroponics) and fish (aquaculture). With it, the use of resources (i.e., water, nutrients, land) is reduced whilst at the same time minimising residues' discharge to the environment. Among its benefits, it allows the production of healthy vegetables and...

Dataset acquired for the study published in the article: "Suitability and optimization of FAO's small-scale aquaponics systems for joint production of lettuce (Lactuca sativa) and fish (Carassius auratus)". This study evaluated the performance of three different small-scale aquaponic systems for the joint production of lettuce and Carassius...

Payoya es una raza caprina andaluza de aptitud lechera que actualmente se encuentra en peligro de extinción. Se ubica, principalmente, en la Sierra de Cádiz y la Serranía de Ronda (Málaga) y se explota en sistemas semiextensivos o semiintensivos donde el pasto natural y en ocasiones cultivado, constituyen la base de su alimentación. En este...

En algunos países del entorno mediterráneo existe tradición de consumo de carne de conejo silvestre procedente de la caza. Sin embargo, las características de la canal y de la carne de esta especie cinegética han sido escasamente investigadas. Los objetivos de este estudio fueron analizar la composición química de la carne de conejo silvestre...

Aquaponics is a sustainable food production system combining hydroponics and aquaculture. Although the domestic/small-scale aquaponic production has proliferated worldwide, there is scarce knowledge about how it is performed. The objective of this study was to determine the profile and motivations of aquaponic producers, the characteristics of...

Elephant grass is a tropical forage widely used for livestock feed. The analytical techniques traditionally used for its nutritional evaluation are costly and time consuming. Alternatively, Near Infrared Spectroscopy (NIRS) technology has been used as a rapid analysis technique. However, in crops with high variability due to genetic...

Aquaponic facilities allow the joint production of fish and plants in a reduced space. This hydroponic technique, combined with vertical farming, is not well studied. The main objective of this work was to compare basil production between horizontal and vertical decoupled aquaponic systems and assess the utilization of supplemental lighting in...

Waterborne diseases pose a significant risk in hydroponic crops, especially those caused by some species such as Fusarium, Pythium and Phytophthora. However, there is evidence of an increase in suppressiveness when using aquaculture effluents, as is the case with aquaponic systems. In this work, the incidence of diseases in hydroponic and...

Apenas hay trabajos sobre el consumo de pastos arbustivo-mediterráneos y su relación con la calidad de los productos caprinos. El objetivo del presente trabajo fue estudiar el efecto del nivel de pastoreo sobre la calidad de la leche de cabras de raza Payoya. Se seleccionaron 16 explotaciones situadas en la Sierra de Cádiz. De enero a mayo se...

Near Infrared (NIR) spectroscopy was evaluated as a fast and easy method for identifying the most interesting cocoa genotypes according to chemical composition, including bioactive compound contents, in more than 80 samples of cocoa beans from the Mexican Germplasm Bank, which were harvested over three years. Clear dif ferences in chemical...

Los sistemas caprinos lecheros tradicionalmente han tenido un manejo basado en el máximo aprovechamiento de los pastos, haciendo coincidir el periodo del año de máximas necesidades de las reproductoras con aquel en el que ofrecen un mayor rendimiento. Con la intensificación de la ganadería, este manejo había tendido a desaparecer, pero, con la...
