Estaciones de plantación / Zai / Tassa

“Zai” es un término que los agricultores del norte de Burkina Faso utilizan para referirse a pequeños pozos de siembra que normalmente miden entre 20 y 30 cm de ancho, tienen entre 10 y 20 cm de profundidad y están espaciados entre 60 y 80 cm. En la región de Tahoua en Níger, se usa la palabra haussa “tassa”. Los términos en español utilizados para describir los pozos zai incluyen “hoyos de siembra”, “cuencas de siembra”, “micropozos” y “pequeños pozos de recolección de agua.” Las semillas se siembran en los hoyos después de llenarlos con uno a tres puñados de material orgánico como estiércol, compost o biomasa vegetal seca.

    20/10/2013 ¿Hace una cuenca de siembra, como el pozo zai, una gran diferencia en cuanto a la humedad del suelo en un suelo arenoso? Debido a que el agua se filtra bastante rápido a través de la arena, usted podría esperar que las depresiones de siembra no tendrían un impacto significativo sobre la humedad...

    "Runoff farming" is identical with "Water Harvesting but for Irrigation Purposes". When the harvested runoff water from un-cropped areas is directed to a cropped area, this technique is called runoff farming. Soil profile acts as a water storage container, but storage in ponds or cisterns is also...
