The ProShot™ Advantage

Overcomes Cool Temperatures

Low temperatures can tie up valuable soil nutrients. In-furrow positioning at planting provides young root systems with an immediately available source of 100% water-soluble nutrients.

Versatile Application

PROshot can be safely placed in-furrow with the seed in most soils or positioned 2x2 from the seed during planting without fear of reduced germination.

Improved Yields

Young plants emerge stronger, plants move quickly through the vegetative stage, earlier and more uniform tasseling occurs, and plants mature faster producing the highest quality crops with top yields.

Plus, ProShot™ can be foliar applied without fear of leaf damage.

ProShot™ Plus

ProShot™ Plus 6-24-6 is a formulation of NPK with a shot of micronutrients, including copper, manganese and zinc. This special formulation provides the macro and micronutrients crops need to reach maximum yield potential.

Banding ProShot™ during planting is more effective and can reduce broadcast P and K rates by one-third to one-half. Banding puts nutrients into the root zone and reduces nutrient fixation. Growers can save just by changing from broadcast to banding.

98G by Calcium Products

Soil pH is the foundation of nutrient availability and critical to maximizing crop yield. The availability of all nutrients is impacted by soil pH levels, especially phosphorus (P).

When soil pH is below 6.0, it can reduce your yield by as much as 30%. Calcium Products’ 98G pelletized limestone is the most effective and consistent product to correct and maintain soil pH.

SO4 by Calcium Products

SO4 supplies a strong initial release of sulfur followed by a steady supply throughout the growing season, perfectly matching plant needs. Averaged over 67 trials across the Midwest, SO4 increases corn yield by 15.4 bushels/acre compared to no sulfur.

ContaiN is a nitrogen management product that pairs with Xcelerated Nitrogen Technology with the urease inhibitor, NBPT, creating a powerful nitrogen management aid that works above and below the soil.

Ideal for pairing with urea or UAN to efficiently increase nitrogen usage and reduce loss due to volatilization and improve below ground efficiency. ContaiN can be used with multiple sources of fertilizer.

Product Advantages

  • Provides above ground protection and below ground efficiency
  • Manages nitrogen availability during key growth stages
  • Improves nitrogen availability and uptake as an additive
  • Helps control volatility
  • Doesn’t harm soil
  • Applies easily thanks to properties that reduce sticking and bridging in blenders and spreaders with urea
