The Almond tree is gradually colonizing the Lands of the Sierra Norte de Cádiz, specifically from the Los Remedios de Olvera cooperative, the implementation of 50 hectares, being the Lauranne-Avijor and Constantí varieties the chosen ones, for different reasons, among which stands out:
- High Productivity
- Low Oversight
- Late flowering
- Resistance to diseases and pests
- Adapted to dry land.
Currently the Almond trees found in the Sierra Norte de Cádiz region, are in the fruit filling phase.
The weather conditions of 2021 are affecting plantations with different degrees of importance, mainly due to the rainy winter we have had. We have been able to verify how the almond tree, either in frank foot or hybrid foot GF-677, does not support conditions of ponding, either on the surface or in deep layers of the soil. The most direct influence we have encountered is the plant death, due to these conditions motivated by the incidence of fungi present in the soil type Brotriosfaeria, Neofusicocum y Phytophthora, in those areas of the soil with the presence of higher clay content or presents a water table that is in the zone of influence of the roots.

For this reason, the Technical Services of the cooperative tries to evaluate the soil conditions for the implantation of almond cultivation., evaluating its possible impact on it. Regarding flowering, because the implanted varieties are Late Flowering, we have been able to rid the late frosts of this year, getting a more than acceptable curd.
Regarding the sanitary state, the incidence is due to Aphid (Myzus Persicae) in sheets, being very important the observation of the first colonies for their control, since by its arrangement in the sheets (underside), when sucking the sap they roll up the leaves protecting them from phytosanitary treatments.
