Characterization of Composted Organic Amendments for Agricultural Use

Initial Development of Melon when Grown in Different Concentrations of Exhausted Peat Organic Compost

“…The availability of nutrients in the initial stages for the melon seedlings was a limiting factor for the growth of the aerial part [6,7], where seedlings cultivated in different concentrations of the exhausted compost generally presented quadratic responses, showing that there is a limit to the availability of nutrients in the substrate. In this way, high concentrations compromise the development of plants, due to the elevation of the levels of salts available in the soil solution which starts to increase its electrolytic and osmotic potential, where the very high concentrations to the seedlings begin to compete with the saturation of the solution of the soil and consequently lose water [5,15].…”

“…The use of organic compounds represents an adequate technique to nourish the substrate that will be used in the initial development of melon seedlings, [5] but you should be aware of the relation between carbon and nitrogen (C/N), where high ratio relationship between these two elements can negatively affect the development of these seedlings as it can cause nutritional deficiencies, mainly nitrogen, for the decomposition of organic matter microorganisms consume the available N in the soil to do all the decomposition reactions [6].…”

“…These organic residues as a source of nutrients become an alternative to reduce expenses with industrial fertilizers [5] and it also provides a better rooting of the seedlings, thus guaranteeing a minimization in post-planting stress, this is due to the greater number of roots, in which they start to seek more nutrients in deeper layers in the substrate profile and in this way greater absorption occurs of nutrients, thus guaranteeing a better development of the plants in the initial stages [7]. In general, plants that receive organic fertilization show greater development of the aerial part mainly of young shoots [8].…”

Microplastics in Soils and Sediment: Sources, Methodologies, and Interactions with Microorganisms

“…In this process, the yard debris is vacuumed through a hose, and all materials, including a significant amount of waste plastic, are also collected. After biodegradation of the yard waste, the community-based compost is distributed on land, including agriculture, suburban, and livestock fields to improve the soil (Epelde et al 2018).…”

Response of corn crop to concentrations of digested bovine manure in humid tropical climate

“…Esto indica que la aplicación de abono líquido bajo un sistema de producción familiar es una alternativa que tiene potencial para incrementar el rendimiento del maíz y evitar el efecto negativo que causa el estiércol de ganado al llegar al agua, en donde se descompone y consume el oxígeno disuelto pudiendo matar por asfixia a peces y otros animales menores (Kumar et al, 2013). El efecto positivo del abono líquido (20 -60%) en el rendimiento se puede explicar de dos maneras (i) el abono aplicado directamente al follaje proporciona nutrientes y metabolitos secundarios producto de la digestión anaeróbica de los microorganismos presentes en el estiércol del ganado (Das et al, 2017) y (ii) el abono líquido que llega al suelo promueve la actividad microbiana nativa, permite el reciclaje de nutrientes y mejora las propiedades químicas del suelo (Eghball et al, 2004;Epelde et al, 2018). En ambas explicaciones, es probable la interacción del maíz con microorganismos nativos que tienen la capacidad de inducción de resistencia o promoción de crecimiento de plantas como reportado por Gond et al (2015) y Lobo et al (2019) en el cultivo de maíz, respectivamente.…”
