A potted trial was carried out in order to study, using the Chaminade technique, the nutrient deficiencies of eleven of the province of CautÃn. Rye-grass H-1 (short rotation) was planted. The treatments used were: complete fertilization, complete fertilization without one of the following nutrients: phosphorus, potassium, calcium, magnesium, sulfur, micronutrients (B, Cu, Zn, Mn, Mo) and a check without nitrogen.
The intensity of any deficiency was evaluated by measuring the dry matter yield obtained per plant-pot, with respect to the complete fertilization. |
