Product of Poland Product made in FuelCal® technology 
OrCal® are modern and smart, Polish organic and mineral products with a triple formula of action.
They contain active calcium hydrate and an organic substance, thanks to which they work comprehensively: they deacidify the soil, improve its fertility and supply the plants with essential nutrients.
OrCal® – a recipe for bigger yields!
… dissolves in water. The essence of quick and effective OrCal® treatment is calcium hydrate and its water solubility – 1.7g/1000ml, which is an excellent, nearly 100 times better result in comparison with the solubility of calcium carbonates (chalk and dolomite) – 0.02g/1000 ml.
Speed of action – effects in the first crop!
The fast solubility of OrCal® in water and the content of organic matter make it work instantly. Deacidified soil and improved soil structure cause thatthe effects are visible in the first crop from application.

Product of Poland Product made in FuelCal® technology We invite you to read the opinions of farmers who use OrCal® products
Soil not fertilized with OrCal®: medium-powdered, pH 4.3, class 4, low plants, showing micro-and macro-nutrient deficiencies, cultivation does not even predict average yields.
Soil fertilized with OrCal®: moderately rich, pH 7.0, 4th class, OrCal® 1.2t/ha dose, stately, healthy, well-rooted plants.
Soil not fertilized with OrCal®: medium-powdered, pH 5.2, class 3 (low, poorly propagated plants, short ears, root system poorly developed).
Soil fertilized with OrCal®: medium-powdered, pH 6.5, class 3, OrCal® 1t/ha before seeding, autumn 2016), higher plants, well-propagated, stately, long, larger number of “floors”, root system proved, well developed, estimated wheat yield – above average.
Soil not fertilized with OrCal®: medium-powdered, class 2-3, pH 5.5.Assessment of overwintering: approx.18-20 plants/m2, weak vigour, root neck with a smaller diameter, weak root system, low silique.
Soil fertilized with OrCal®: medium-powdered, class 2-3, pH 6.5 (OrCal® 1t/ha dose top-dress, autumn). Assessment of overwintering: approx. 25 plants/m2 +20% relative to the control field, visibly better vigour, root neck with a larger diameter, stronger root system, greater thickness of the field (dense rape), large silique, plants clearly more resistant to periodic droughts.
Farm: corn growing
Voivodeship: Warmian-Masurian, near Lidzbark Warmiński
Soils: Classes 3-5, medium rich, pH 5.0-6.0
OrCal® pHregulator application: in loose form
Fertilization period: spring 2015
OrCal® dose: 0.7 t/ha
Effects: well-nourished corn in spite of drought, nicely stained leaves, good vigour, even field (stable crop), well-grained cobs. Increase in pH to 6.8-7.1
OrCal® dose: 0t/ha
Effects: maize clearly in a weaker condition, poorly tolerated periodic droughts, lower yield of green mass and starch content in the grain.
Farm: winter wheat cultivation
Voivodeship: Warmian-Masurian, area: 2.5 thousand hectares
Soils: moderately rich, pH 5.0-5.5
OrCal® pHregulator application: in loose form
Fertilization period: autumn 2016
OrCal® dose: 1t/ha
Autumn 2016: in relation to the control field (OrCal® 0t/ha) we observed clearly better emergence, wheat intensively spread, good preparation for winter, better wintering
Spring 2017: When compared to the control field (OrCal® 0t/ha) we observed better overwintering of the plantation, wheat that intensively propagated in the spring, better color of leaves, better spring vigour
Farm: growing oats
Voivodeship: Lubuskie, area of 140 hectares
Soils: medium-rich, pH up to 5.5
OrCal® pHregulator application: in loose form
Fertilization period: autumn 2015, prior to seeding
OrCal® dose: 1 t/ha
Grain on the fertilized bed OrCal® pHregulator (1t/ha) – clearly better developed root system, straw and grain yields clearly higher, compared to the plantation not fertilized with OrCal® (control field – OrCal 0t/ha.
The yield on the test field fertilized with OrCal® – about 5.5-6t/ha compared to 1-1.3t/ha in the control field.
Farm: seed farm, cultivation of beets, 300 hectares
Voivodeship: Lower Silesian, Jawor district
Soils: lack of information
OrCal® pHregulator application: in loose form
Fertilization period: autumn 2016
OrCal® dose: 0.7 t/ha
Beet at a low initial pH stand – 5.4 pH
Fertilizing with OrCal® pHregulator dynamically adjusted the pH of the soil to 6.5.
The launch of phosphorus resources from the soil, very good vigour of plants, with large underground (root) as well as aboveground (leaves) parts. Extremely good yield (number and quality of seeds). Very good condition of plants.
Farm: agricultural farm, Medicago crops, 290 hectares
Voivodeship: Warmian Masurian, Grajewo district
Soils: lack of information
OrCal® pHregulator application: in loose form
Fertilization period: autumn 2017
OrCal® dose: 1 t/ha Medicago culture in clean sowing 40ha, 24ha fertilization OrCal® pHregulator – 1t/ha pre-sowing, 16ha control – without OrCal® fertilization.
Medicago in the field fertilized with OrCal® showed a dynamic growth and definitely higher yield of green matter. Medicago is dense, rich, forming a very high quality protein feed. In the control field (0t/ha) – medicago was definitely weaker, with significantly lower rate of growth, lower yield of green mass, visible greater weeds (in places with lower pH weeds clearly compete with medicago (+ acidophilic weeds).
According to the estimate of the farmer one should expect (+1) additional cut from the OrCal® fertilized plantation, compared to the part of the field where no fertilization was applied.
With such a high medicago yield, farm expenses for other protein feed (post-extraction rapeseed meal, soybean meal) will be much smaller.
Using a digger we made excavations in the field where OrCal® pHregulator was sown and in the field where OrCal® was not used. See what turned out…
