Micronized limestone and dolomite
Lately there has been significant increase in demand for micronized limestone and dolomite because the same are used for the improvement of natural, ecology friendly breeding of plants and cattle. At the same time, there is no need for use of the artificial fertilizers that are also more expensive. Company Japra AD is well known in the region as the only company that has quality raw materials and technology capacities for the production of the micronized grains. The quality of these products is verified through own laboratory but also through authorised Intitutes so all products have Quality Certificates. In year 2011 the interest for these products is increasing rapidly in the country but also abroad (Republic of Croatia, Holland etc.).
KALCIT - limestone, 25 kg bags
It is used for neutralization and activation of acid soil (granulation 0 - 1 mm). It is dispersed to the soil by using standard equipment for fertilizing. On smaller fields it is possible to disperse it manually. Besides that it improves the quality of the soil and decreases the acid level, it also regulates the humidity of the soil and prevents the plants to get dry in reasonable time frame. Because it is rich with calcium, it is used as an addition for the livestock food (cattle, poultry, pets, etc.).
KALCIT - micronized limestone, 25 kg bags
It is used for foliar fertilization of plants by spreading vapor cloud to the leaves of plants. For that purpose the size of the limestone has to be less than 0.025 mm. In that way total yield is increasing, the fruits are in average bigger, the time for storaging fruits is extending, the needs of the plants for water is reduced as well as usage of expensive pesticides, etc.
Products are 100% human, animal and plants friendly.
