Nut and Pecan Trees Plantation
Taking good care of our Nut and the Pecan Trees is fundamental to obtaining an exquisite fruit that will reach consumers in an excellent state. For this, we have considered essential aspects such as the farm’s agronomic conditions, which are exceptional, a privileged area in Andalusia, such as the Guadalquivir valley, next to the river bank that bears its name, which implies that the progress of the tree and the fruit in all its vegetation period is unbeatable, resulting in high quality nuts.
Another fundamental factor is choosing quality plants, so that we selected these plants among plant nurseries in Spain and several countries around the world.
Cutting-edge technologies have been followed to level the land, which is essential in every planting initiation. To achieve this as accurately as possible, we used a laser beam equipment to avoid damaging the soil’s physical and chemical composition.
Another state-of-the-art technology that we are using is the stomatal pressure chamber. A device to apply air pressure to a leaf, where most of it is inside the chamber, but a small part of the petiole is exposed to the outside of the chamber through a seal. The amount of pressure needed to make the water appear on the cutting surface of the petiole will depend on the pressure of the blades.
We also use the Diviner 2000, a moisture measurement system for soils, which records moisture at the different depths of the crop’s root zone. It incorporates the cutting-edge EnviroSCAN technology.
The soil’s texture and structure determine its capacity to retain water. We use an irrigation system that has 4 dripper lines; a very efficient and respectful method, in terms of water consumption.
Fertilizers are placed directly in the area of influence of the root system, perfectly dissolved and therefore more easily absorbable by the plant, thus we obtain optimal conditions for its development.
When designing the plantation, we took into consideration a series of things, such as geographical orientation in order look for as much solar irradiation as possible, the cropping operations and the distribution of pollinators. Planting density is appropriate to optimize maximum treetop development, allowing proper access to the amount of light required.
We use small little low ridges. With this technique, we get the water to circulate or remain in the lower part of the soil, being accessible by the roots, but without flooding the neck of the plant and thus not causing fungal diseases due to humidity. This way, the first roots will be protected to facilitate immediate root development.
With a manual planting system, we plant our trees with great care adjusting the plant to the size of the hole. Hole opening is proportional to the size of the root system. In the settlement, we have considered that the grafting point must be above ground level. Once planted, we place the training in the direction of the prevailing winds.
Application of mycorrhizae in nut and pecan trees
When planted in the soil, mycorrhizae, which is a product of natural origin isolated from strains of endo-mycorrhizal fungi or arbuscular Vesicular Fungi, usually present in the world’s soils, are also added to the roots. This fungus colonizes the roots, without causing any damage to the plant and subsequently developing a network of external hyphae that extend and branch in the soil. They vitalize plants for life in one single application. Helping to improve nutritional deficiencies. Reducing the stress resulting from transplanting and final planting, they act as a biological control for the stress caused by extreme temperatures, intense droughts, salty, contaminated, damaged soils, extreme Ph and other factors.
It generates better resistance against pathogenic organisms (less applications of pesticides and fungicides). It increases the tolerance of the roots against the attack of pathogenic microorganisms and nematodes. It reduces the possibility of being infected by Phytophthora, Aphanomyces, and Pythium, decreasing vascular damages such as Fusarium and Verticillium, and parasitic nematodes forming nodules, gills that cause lesions such as Meloidogyne and Pratylenchus among others, and reduces chemical applications throughout the plant’s life, so that it is considered as a “vaccine effect.”
