Pero existe una gran incertidumbre sobre las características que debe reunir un brinzal para aumentar sus probabilidades de éxito en el campo. Algunos estudios han mostrado que la fertilización en vivero permite una mayor supervivencia y crecimiento en campo. Sin embargo, en estos experimentos, las variaciones en el estado nutricional no se pueden desligar de los cambios morfológicos que promueve la fertilización. Para evaluar la importancia del estado nutricional, frente a las variaciones morfológicas inducidas por éste, hemos evaluado el comportamiento en el campo de brinzales de una savia de Quercus ilex subsp. ballota no fertilizados y brinzales a los que se aplicó fertilización tardía (posterior a la parada otoñal de crecimiento de la parte aérea). Nuestras hipótesis son: (i) la fertilización tardía permite mejorar el estado nutricional de los brinzales sin variar su tamaño y (ii) con ello, se aumenta la supervivencia y el crecimiento de los brinzales en el campo. La fertilización tardía no afectó al tamaño de los brinzales, pero mejoró su estado nutricional. En campo, la supervivencia fue muy elevada antes del primer verano (&gt;98%), disminuyendo después del mismo hasta un rango de valores de 65-100%. En ningún caso la supervivencia estuvo relacionada con la fertilización en vivero. Por el contrario, la tasa de crecimiento antes del verano fue inferior en plantas no fertilizadas, invirtiéndose esta tendencia durante el verano. La tasa anual de crecimiento fue superior en las plantas fertilizadas, confirmando parcialmente nuestra hipótesis. La fertilización tardía representa una técnica sencilla para reducir el uso de fertilizantes en vivero, produciendo brinzales de pequeño tamaño pero elevada capacidad de respuesta en campo.

Biosolids had a positive effect on P. halepensis growth, and a negative effect on Q. ilex growth at the highest rate when seedlings were in contact with biosolids.
