¿Qué áreas del conocimiento me pueden <br> aportar a la ejecución del proyecto? para un huerto
tensa zangetsu [6.8K]

Answer:

Conocimientos que pueden resultar muy útiles al momento de planificar un huerto:

- biología vegetal (características de las plantas que queremos producir)

- agronomía (características del terreno utilizado)

- condiciones ambientales (meteorología), como así también la disposición del lugar

Explanation:

Para iniciar un huerto en casa es necesario tener en cuenta una serie de factores que pueden influenciar en gran medida el éxito del proyecto:

-Tener en cuenta las características de las plantas que queremos producir es fundamental para lograr un óptimo crecimento. Por ejemplo, plantas que no resisten las heladas podrían morir en ciertas regiones, con lo cual las plantas deberían encontrarse en estos casos protegidas durante su desarrollo (por ejemplo, mediante un invernáculo).

- Buscar lugares bien iluminados. La presencia de luz es un factor fundamental para el crecimiento de las plantas.

- Riego y/o precipitaciones: tener en cuenta las necesidades hídricas de las plantas que queremos producir.

- Suelo: utilizar tierra abonada suele ser la mejor opción para brindarle a las plantas la mayor cantidad de nutrientes y así garantizar un óptimo crecimiento. En el caso de usar macetas, la presencia de huecos o el uso de vermiculita puede ser de gran ayuda para permitir la escorrentia del agua.

- Espacio: es necesario tener en cuenta el espaciado entre plantas para que puedan crecer normalmente.

-Tener en cuenta las plagas (insectos, nemátodos, etc) que podrían afectar el crecimiento de las plantas.
