BroadMan 20

BroadMan 20 is a low analysis, highly water-soluble, uniformly granulated manganese fertilizer specially designed to overcome the limitations of traditional broadcast manganese fertilizers.

IT IS WELL KNOWN THAT MANGANESE IS AN ESSENTIAL PLANT NUTRIENT. Deficiency disrupts plant enzyme functions and reduces yields and quality.

Broadcasting traditional granular manganese fertilizers is generally less effective than banding or foliar sprays, especially on high-pH soils. When manganese fertilizer is broadcast, reactions with the soil convert much of the fertilizer manganese to unavailable forms, reducing the effectiveness of the application.

Manganese is immobile in the soil and generally moves only a fraction of an inch from the point of application. Because root interception is the primary uptake mechanism for manganese, increasing granule density in the soil improves availability. Broadcasting traditional high-analysis, low water-soluble granular manganese reduces the probability of roots contacting the fertilizer. BroadMan 20 is specially manufactured to increase granule distribution and maximize root contact and nutrient uptake.

Most manganese fertilizers are insufficiently water soluble to provide adequate plantavailable manganese. Generally manganese fertilizers that are highly water-soluble are high-analysis (32% Mn or higher) products that do not provide adequate granules for maximum root contact.

To improve the performance of broadcast manganese applications, AAT introduces BroadMan 20, a new product that provides low manganese analysis, more granules per acre, and high water-solubility. With BroadMan 20, fall and pre-plant broadcast applications of manganese become a more effective option for preventing manganese deficiencies. BroadMan 20 can reduce the need to make in-season “rescue” treatments with foliar manganese.
