Description
Phosphorus is a fundamental element for plant metabolism and an essential component of many of the most important molecules in the cell (DNA, phospholipids, ATP, etc.), but often, the phosphorus present in common fertilisers is not very effective: phosphorus in soluble chemical form, as soon as it is released from fertilisers, is almost immediately immobilised in the soil and rendered unusable by plants.
There is therefore a need to use a form of phosphorus that can remain completely mobile and therefore absorbable by the plant, regardless of soil type and pH.
Optimus PK is a phosphorus-based fertiliser in which the element is present in a particular chemical form, which allows it to be extremely effective in all types of soil, including calcareous soils or those with high pH.
To further increase the effectiveness and availability of phosphorus, we recommend applying Optimus PK together with Sun rooting pro®: with this technique, the phosphorus is complexed by the humic substance and remains available to the plant even in the most unfavourable conditions.

Instructions for use
A soluble powder product (the product is highly soluble even in cold water) with extremely high nutritional effectiveness. This product has been designed to address the widespread problem of low phosphorus availability in soils (very often significantly lower than the requirements of different crops).
