| dc.description | This document details the analysis of nutrient absorption curves in corn and rice crops. The conclusions determine that during the tillering phase, it was observed that nitrogen and potassium were the nutrients with the highest absorption capacity. While potassium exhibited continuous uptake throughout all developmental stages, nitrogen showed no uptake in the stem elongation and grain development phases. It stands out that potassium was the nutrient with the highest overall absorption rate. Phosphorus and calcium exhibited absorption capacity in all phases of the process, unlike magnesium, which did not show absorption during the stem elongation phase. Sulfur and iron do not present absorption during the stem elongation stage. The absorption of copper and boron is not observed during the seedling and flowering stages, while zinc does not present absorption during the stem elongation stage. In corn production, the primary micronutrients that are assimilated in significant concentrations are iron and manganese. Likewise, they are the micronutrients that are found in higher concentrations when using the entire plant and removing it from the ground. To achieve high yields, corn must reach an optimal physiological state at each stage of development, with adequate availability of nutrients, particularly when these are required in greater quantities (approximately when 5-6 leaves develop). This guarantees robust leaf growth and high efficiency in the conversion of intercepted radiation. | es_ES |

| dc.description.abstract | El presente documento detalla el análisis de curvas de absorción de nutrientes en cultivo de maíz y arroz. Las conclusiones determinan que durante la fase de macollamiento, se observó que el nitrógeno y el potasio fueron los nutrientes con mayor capacidad de absorción. Mientras que el potasio exhibió una absorción continua a lo largo de todas las etapas de desarrollo, el nitrógeno no mostró absorción en las fases de elongación del tallo y desarrollo del grano. Destaca que el potasio fue el nutriente con la mayor tasa de absorción en general. El fósforo y calcio exhibieron capacidad de absorción en todas las fases del proceso, a diferencia del magnesio, el cual no evidenció absorción durante la fase de elongación del tallo. El azufre y el hierro no presentan absorción durante la etapa de elongación del tallo. La absorción de cobre y boro no se observa durante las etapas de plántula y floración, mientras que el zinc no presenta absorción durante la etapa de elongación del tallo. En la producción de maíz, los micronutrientes primordiales que se asimilan en concentraciones significativas son el hierro y el manganeso. Asimismo, son los micronutrientes que se encuentran en concentraciones más altas al emplear la planta completa y retirarla del terreno. Para lograr altos rendimientos, el maíz debe alcanzar un estado fisiológico óptimo en cada etapa de desarrollo, con una adecuada disponibilidad de nutrientes, particularmente cuando estos se requieren en mayores cantidades (aproximadamente cuando se desarrollan 5-6 hojas). Esto garantiza un crecimiento foliar robusto y una alta eficiencia en la conversión de la radiación interceptada. | es_ES |
