The inclusion of OCC colloidal nutrients into the nutrient mix of hydroponic greenhouse cultivation of cherry tomatoes raised the maturity uniformity of a producer in Almeria, Spain, and enhanced its weekly Grade A delivery of Cherry Tomatoes.
Including OCC colloidal nutrients into the nutrient mix of aeroponic greenhouse cultivation of butterhead lettuce raised the nutritional value of measured parameters ranging from 1% to 48%, highlighting the improvement in the absorption of minerals and nutrients.
A major European animal feed producer conducted an OCC colloidal nutrient [with amino acid] trial on MESETA Barley by reducing herbicides and nitrogen input by half. The results showed an increase in commercial productivity by 23%, with revenue per hectare improvement by 32%.
In a potato farm in the Avila region in Spain, OCC colloidal nutrients [OCC with amino acids] were applied on VITALIA variety potatoes in combination with crop protection chemicals at various dosage reductions to assess their impact on control and yield.
Three treatments were applied to compare the performance against neighbouring plots which adopted standard cultivation practices. The results showed a significant yield improvement of 62 tons per hectare on the OCC plot over adjacent plots’ yield of 40 to 45 tons per hectare.
A comprehensive study on the use of OCC on a popular tomato variety was conducted in 2009 by a consultation company in Spain. On a five-hectares tomato field, 2.5 hectares used the standard growing protocol with the regular dose of protection and control chemicals as recommended on products’ labels. On another 2.5 hectares plot, OCC was included in the control sprays, but all dosages were reduced by 50%. Results showed a 14% higher yield on OCC plots with 20% higher Brix levels and 50% chemical savings per hectare.
A renowned vineyard in the Ribera del Duero region in Spain conducted a two-year trial with OCC on the Tempranillo variety in 2014 and 2015. The viticulturist applied three applications in both campaigns to compare the efficacy of colloidal protocol against the vineyard’s standard protocol; At 20-40cm sprouting, at the start of flowering, and around 50% veraison. In addition, the vineyard combines nutritional and protection spray in the same tank mix to reduce the application cost. Results showed OCC improved 25% yields in both campaigns despite a 30% reduction in nutrients and chemical input over two harvests.
A rubber plantation in Thailand has many rubber trees over 20 years old with BNS, the Bark Necrosis syndrome, which leads to a sharp fall in latex production and substantial economic losses. Over the years, many of these diseased trees have been eliminated and replaced with young rubber trees that do not produce latex. The plantation manager applied OCC as a foliar spray and soil conditioner weekly on selected trees with the BNS conditions and young, immature trees to observe the outcome. After the application, the BNS conditions were reversed, and young trees also started producing latex.
A trial in Brazil to control common rust (Puccinia sorghi) on DKB 290 PRO3 hybrid corn with fungicides. Results showed that the inclusion of OCC micronutrients allows the reduction of fungicide dosages from 15% to 50%, all of which had no impact on the commercial productivity of the corn and, in fact, with marginally higher yield over a standard labelled dose fungicide treatment.
A major citrus grower in Brazil tested OCC with various dosages of Pyrethroids insecticides to evaluate the control efficacies of psyllids that cause the citrus greening diseases. The results showed that the effectiveness of the Pyrethroids was enhanced, allowing them to have better control over a total labelled dose of insecticide despite dosage reductions by up 50% or more.
OCC was introduced into the management protocol in Vietnam’s Thai variety asparagus farm. The result was a significant increase in output and quality, doubling the growers’ total revenue.
