Available for both In-Furrow or On-Seed treatment, Pivot Bio’s Proven® 40 provides a unique and highly-advanced option for your operations nitrogren management program. Proven® 40’s microbes form a symbiotic relationship with the corn plant to be able to take nitrogen from the air and create the ammonia that plants need to grow and thrive. Dependent on your operational history, with the addition of Proven® 40, you could possibly reduce your nitrogen applied by 40 units. It’s simple to use, requires no additional trips accross the field, has a lower leachability than synthetic nitrogren, and can help lower your carbon footprint.  

Advanced-Cal *NEW*


Have you ever heard of liquid lime? Call Tony to learn more about this option we can provide!


Advanced-Cal is a blend of liquid calcium for nutrilizing soil acidity. This blend also contains amino acids, humic acid, root growth stimulators, germinators, seed starters, and other micro-nutrients.

Phosphorus (P) is essential for crop growth. No other nutrient can be substituted for it. The plant must have phosphorus to complete its normal production cycle. It is one of the three major nutrients: the other two being nitrogen (N) and potassium (K).


Potassium (K) has a great impact on crop quality, including increased kernel weight and kernels per ear in corn. It also improves oil and protein content in soybeans. Potassium is vital to photosynthesis. Sufficient levels of potassium also improves plant health, stalk strength, and tolerance to drought stress.


Aglime, Pell Lime, Adv-Cal (NEW)

Aglime is crushed limestone used for soil treatment, primarily to reduce soil acidity. Pell Lime and Adv-Cal are other options we provide that provide similar achievemnts. Contact Tony to discuss the differences and the options best suited for you and your ground. Using aglime to change the soil from acidic to nearly neutral benefits crops by maximizing availability of plant nutrients. When solids are very acidic, over half of the applied nutrients can be tied up in the soil and not available to the plant. The optimum range of pH for corn is 5.5 to 7.5. For soybeans, the optimum range is 5.0 to 8.0. 



Micro-nutrients are essential plant mineral nutrients taken up and utilized by crops in very small quantities.

Traditionally, we have relied on what was naturally present in the soil in combination with added impurities in fertilizers and pesticides as the main source of micro-nutrients for crop growth. Now, deficiencies of micro-nutrients have been diagnosed more frequently, and many farmers are beginning to take a look at their general availability.


Bollmeyer Inc. has cutting edge technology and equipment that has allowed us to stay competitive in the industry. Our 4 box spreaders are being utilized to spread not only fertilizer, but micro-nutrients as well.
