This product is recommended for foliar application and hydroponic systems. While soil application is possible, foliar feeding is preferred.  

Soil Application  

In soil conditions, manganese in the EDTA complex can be easily replaced by iron. Therefore, optimal results are achieved when iron levels in the soil and irrigation water are low; otherwise, foliar application is advised. Dissolve the product in water and apply it close to the plants or trunks. After each application, water thoroughly to enhance nutrient absorption. Ensure the solution reaches the roots for effective uptake. Dissolvine Manganese EDTA 13% is fully water-soluble, making it highly suitable for fertigation.  

Hydroponics  

In hydroponic systems, Dissolvine Manganese EDTA 13% enhances the effectiveness of iron chelates. Although the irrigation water's pH is typically around 6, the fertilizer tank's pH can be much lower. This product remains stable within a pH range of 3 to 10. Avoid direct contact between Dissolvine Manganese EDTA 13% and concentrated acids.  

Vegetable crops such as tomatoes and cucumbers require 10 µmol Mn/l (0.55 ppm) consistently, while flower crops need 5-10 µmol Mn/l (0.27-0.55 ppm). Refer to Table A for equivalent quantities in grams.  

Foliar Application  

Foliar feeding ensures a rapid response and is recommended when immediate correction is needed, or when soil application is impractical, expensive, or impossible due to conditions like extreme soil wetness. Repeated applications may be necessary. To improve leaf coverage, it is advisable to add a wetting agent, with efficacy further enhanced by adding urea. Dissolve the product to an appropriate concentration and apply it using spraying equipment. The final solution's pH should be below 6.5, and the EC should be below 1. Test dosage rates for specific crops on a small scale first. For severe manganese deficiency, repeat the application after two weeks. Begin treatment promptly.
