Potato cultivation is characterized by a high use of
inputs, which results in soil degradation and contamination.
Crop rotation is a good practice to counteract these problems.
This study aimed to assess the sustainability of three rotation
sequences (potato-pea-potato, potato-oat-pea and potato-potatooat)
using the sustainability assessment method...
A variety of established tools are available for agricultural sustainability assessment at global, regional, and farm geographical scales. However, no assessment has been reported in research literature to indicate their ability to provide insights about the most sustainable cropping system at plot level or experimental unit. Despite the environmen...
Many soil quality indicators (SQI) are generally used to evaluate the medium- and long-term variation of soil quality. The possibilities are reduced when this variation is planned to be evaluated through seasonal experiments. The objective of this work was to find the most feasible SQI to be used at the plot scale in seasonal experiments. Five SQI...
Some authors raise concerns about the validity, reliability, and transparency of indicator selection in agricultural sustainability assessments. In this regard, several selection criteria have been put forward for sustainability assessments at the farm, regional, country, or planet levels. However, assessments at the plot or experimental unit level...
Las evaluaciones de sostenibilidad son el mecanismo más adecuado para determinar si un método, alternativa o tendencia de producción de cultivos es viable desde el punto de vista ambiental, económico y social. Estas evaluaciones se realizan por medio de herramientas basadas en indicadores, algunos asociados con las propiedades, la composición, los...
Agricultural sustainability assessments have gained high importance during the last decades. Different tools have been developed for these assessments, such as the Sustainability assessment methodology oriented to soil‐associated agricultural experiments (SMAES). SMAES quantifies the current sustainability of the different treatments evaluated in e...
Despite its low water- and cation-retention capacity, rice husk is the most common substrate in soilless cultures (SLC) in Colombia; however, its availability has decreased due to the diversification of its use. The most relevant chemical and physical properties of eleven organic substrates and seven minerals were characterized to determine their f...
At the farm level, the most common social indicators are hours of work (wages) and the seasonality of labor. The magnitude of physical effort that workers invest in agricultural activities is not used as an indicator. In this sense, the work effort indicator (WEF) is proposed. To calculate WEF, five degrees of work effort (GE) were established; a c...
In potato crops in Colombia, fertilization has low efficiency in terms of absorption of nutrients by the plant due to fixing, leaching or volatilization processes. To counter this phenomenon, we evaluated the effect of the split application of fertilizers on potato plants and soil. Five treatments were evaluated: Control - fertilization used by far...
Andean blackberry is usually sown in soils without salinity limitations, but the use of fertilizers based on sources of chemical synthesis that do not take into account nutritional requirement or the use of chicken manure without composting can cause a long-term salinity effects. In this research, the effect of different concentrations of a saline...
The need to understand and evaluate the quality of soils in agricultural production systems is an issue of increasing importance today because of the determination of impacts from management practices on the sustainability of this resource. The objective of this review is to provide an overview of the concept of soil quality and indicators for its...
The application of organic amendments is a practice that is done regularly in crop systems in order to improve the physical and chemical properties of the soil and provide nutrients such as nitrogen (N). In order for plants to absorb it, much of the N that is contributed through organic amendments must be transformed from its organic form to its in...
RESUMEN En la Granja Experimental ENDESA, localidad de Soacha (Cundinamarca), se llevo a cabo un ensayo bajo condiciones de invernadero con el objetivo de evaluar el efecto de la incorporación de un material orgánico proveniente del humus de lombriz producido en la misma finca, sobre el rendimiento y calidad comercial de un cultivo de tomate (Solan...
