⚠️ Tolerated

Solución de aminoácidos obtenida de la queratina de la lana, usada como bioestimulante foliar durante el crecimiento.

Application

Application description: En pulverización foliar, sobre todo durante el crecimiento vegetativo y en cultivos de hoja.

Dose: 1 %: 1 litro en 100 litros de agua.

Tips

La lana contiene hasta un 95 % de queratina, una proteína que el hidróxido rompe en aminoácidos. Producto muy cáustico: manipúlalo con protección, guárdalo etiquetado y nunca lo apliques puro. Su efecto mejora si se combina con sustancias húmicas (hidrolizado de humus). La hidrólisis química de proteínas no está prevista para la agricultura ecológica en la UE.

Preparation process

1) Con guantes, gafas y mascarilla, disuelve el hidróxido en el agua, dentro de un bidón de plástico resistente, removiendo hasta que se disuelva por completo: la mezcla se calienta. 2) Añade la lana y remueve para que se deshaga lo más posible. 3) Deja reposar una noche, tapado. 4) Retira los restos de lana que no se hayan disuelto: el líquido está listo.
