Thank you blairs. But as I said, trees are dying when they are much older. I understand that the first two years are fundamental but it is not feasable for me to irrigate such an enormous area as the topography is quite irregular. Previous to the plantation, land was used for many years to grow cereals. Organic matter was insignificant. Today, after ten years, soil has accumulated a great deal mainly because trees were planted on leveled curves or lines reducing erosion to minimum values. Still, trees continue to die even after a well developed root system.
