New olive groves and pistachio rootstocks (Pistacia Terebintus and Atlántica), are at the beginning of maximum root development. So, any difficulties they have will lead to roots with less vigor and less volume, causing less accumulation of reserves. In this way, plants would be more susceptible to harsh summer conditions and would have less adaptability to our soils.
We have floors with very diverse textures, but they all agree on an alkaline pH (ph > 8), and with a clay percentage higher than 30%. With those characteristics, the possibilities of micronutrient blocking (Five, Magnesium, Boron and Molybdenum) and lack of soil structure (less aeration), will result in less growth, both root and, so, foliar.
To counter the aforementioned negative effects, We recommend that farmers apply short and frequent irrigations during the summer (5-10 liters of water per foot and with a frequency of 15 days) adding in the same application Humic and Fulvic Acids (10-25 ml / tree) plus a Rizostim root (1 liter / 1000 liters of water).
