METHOD OF APPLICATION
HUMAC Agro can be applied to all commonly grown staple and specialty crops/ including ornamental greenery and lawns/ except those that require significantly different soil pH compared to neutral e.g. blueberries. The basic dosage of the product is 200-500kg /ha.
Humic acids require some time to fully reveal their positive effect on soil and plants. Therefore, the best to apply the product is in the period from autumn to early spring before planting. However, it can be applied at any time during the growing season. For best results, it is recommended to work in the product into the top 10cm layer of soil. If conditions do not allow this type of application, the product can be easily spread on the soil surface.
Repeat applications are recommended after every 3-4 years.
During this whole period, we recommend reducing the volume of all mineral fertilizers and especially nitrogen fertilizers by up to 30-50% in the area where HUMAC Agro was used, compared to regular application rates based on the standard fertilizer application calculations.
HUMAC Agro has a positive effect on soil fertility, production quality and overall profitability of crop production. However, in addition to its use, it is necessary to observe the generally applicable principles for sustainable agriculture
