Ferttybyo and Orgaplant Organic assay in olive tree

Agriculture has so far been one of the most important human activities contributing to the increase of chemical contaminants in the soil. This contamination was unavoidable because crops must be treated to avoid pests and achieve optimal production.

In recent times, biofertilisers have become a very interesting option due to their capacity to boost the natural production of crops and adapt it to the quality standard set by the industry without compromising the environment.

At Arvensis we have been specialists in plant nutrition for two decades and that is why we believe that an ecosystem-friendly and highly efficient agriculture is not only possible, but also an obligation to the future.

Products

Two organic soil products were tested in this assay:

FERTTYBYO

A product of which we have already spoken to you on some occasions. Formulated with the exclusive ARV20 strain which has a great biofertiliser and biostimulant potential.

ORGAPLANT ORGANIC

It is specially formulated to improve the soil of our crop and consequently increase its performance.

ORGAPLANT ORGANIC not only improves the plant substrate, but also prepares the soil with structure and nutrients suitable for the FERTTYBYO bacteria. They are a very suitable combination if we want to revitalise our soil.

Assay data

The products were applied together and compared with a control plot. In the treated plot 40 nitrogen fertiliser units (30% of the usual fertilisation) were reduced. In this trial, the different macronutrients and micronutrients present in the leaves of the trees of the treated plot and the control plot were evaluated by means of foliar analyses carried out every two months (28 May, 28 July and 28 September).

In addition, some qualitative parameters of the olives were also assessed, such as the fat content of the olives and the proportion of fat in the dry extract (7 October, 20 October and 24 October).

Results

This study produced an increase in the different nutrients in the treated plot in relation to the control plot, specifically in the case of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S), boron (B), zinc (Zn) and manganese (Mn).

This effect was quite visible in nitrogen, which, although at the beginning of the trial was lower in the treated plot and with a reduction of 30% in relation to the control, two months after the application of the trial products it presented a higher value than the control plot, in which no fertilisation reductions were made.

Thus, it is concluded that the application of these products completely covered the fertilisation reduction needs of the treated plot.

In terms of yield, there was also an increase in the plot treated with the two test products compared to the control. This increase was more than 500 kg of olives per hectare as can be seen in the graph.

Figure 2 Final result of olive production measured in (kg/ha) in both the treated and control plantations.

There was a considerable saving in fertiliser, around 80 €/ha. Apart from these savings, the application of these products led to an increase in productivity and a significant increase in fat content, resulting in an increase in yield per hectare of approximately €2,600. This is shown in the graph below.
