Relaciones fósforo-zinc en tres suelos ácidos de Costa Rica, 2: absorción de los elementos por tomate [Lycopersicon esculentum] en el invernadero.

In a greenhouse experiment with tomato as indicator plant and using three acid, low Zn soils from Costa Rica the effects were studied of four P levels (zero, sufficient to supply 36 ug/ml of available P, twice and four times this amount) and four Zn levels (zero, sufficient to supply 4.5 ug/ml of av...
