Application
A lot of farmers consider compost only as a source of nutrients for their soils. The truth is that Bio Agro Oliva provides a lot more than just nutrients by inoculating the soil with various microorganisms and through the high content of organic matter. Apart from fertilizing, it contributes to the health of the plants and the retention of soil nutrients and water, as well. Bio Agro Oliva can be considered as a sort of "yeast" that even in small quantities can give remarkable results.
The dosage mentioned further down is indicative and may be increased or decreased depending on soil, irrigation, spacing of plants, age, condition and yield of the crop, climate, etc. For professional use, an initial soil analysis is recommended, in order to calculate with accuracy the quantity of required Bio Agro Oliva and possible complementary nutrients from other sources.
Superficial incorporation of Bio Agro Oliva with appropriate machines or tools is proposed (disc harrow, cultivator, digging), depending on the case. Bio Agro Oliva should not be buried deeper than 10cm, as microorganisms need air to work.
The best time for fertilizing is just before the starting of the cultivation period. When plant growth starts, Bio Agro Oliva should be close to their roots.
For olive trees, vines and perennial plants, fertilizing is carried out late in winter (at the start of pruning). For annual crops, the time of fertilizing coincides with the cultivation of the soil before seeding or planting. In case Bio Agro Oliva is only used on the soil surface, without incorporation into the soil (for example, in a ditch around the plant), the results take some months to become evident.
Bio Agro Oliva can be used as a substrate component in seedbeds and pots, together with other materials (soil, peat, perlite, etc.). The percentage in the final mixture varies, depending on the use of the substrate.
There are no problems if Bio Agro Oliva is overdosed. Plants can grow even in a substrate composed of 100% Bio Agro Oliva. However, the European Union has enforced a peak application limit for the protection of ground waters from nitrogen pollution. This limit (17kg of nitrogen/1000m2 or 1080kg/1000m2 of Bio Agro Oliva) applies to some crops (for example, organic agriculture in some EU countries) or to certain sensitive regions.
