YaraVita® POWERBOR™ Ca
YaraVita® POWERBOR™ Ca
The fluid formulation makes it easy to measure, pour and mix the product in the spray tank, while giving the highest nutrient content.
The product is specifically formulated to provide maximum crop safety. This helps to ensure that application will not cause damage to the crop which can reduce it's market value.
The purity of raw materials selected for this product makes it safe for application to the crop and helps ensure that the harvested produce will not be rejected at any point in the supply chain.
A controlled particle size gives quick uptake and long lasting effect. This reduces the need for repeat applications saving both time and money.
A broad tankmixability makes it easy to co-apply the products with agrochemicals, saving both time and money. Just as important, free access to Tankmix information online or via smart phones makes it quick and easy to check whether products can be co-applied.
