Compare Us vs Others

We store gypsum inside

  • Gypsum stays dry for best possible spread pattern
  • Moisture content consistent, doesn’t gain weight from rain
  • We have capacity to store 6,000 tons of gypsum inside and out of the rain

They pile in your field

  • Time is wasted
  • Product is lost loading out of and cleaning up piles

We leave a minimal footprint on your soil

  • Gypsum delivered in belt trailers loaded directly to applicator with belt conveyor
  • No pile, no lost product, least possible compaction

They compact your soil

  • Compacted soil in area where loaded trucks dump, turn, and a loader fills applicator
  • Soil is compacted

We don’t leave piles in your field

  • Less waste and clean up
  • More efficient application
  • Double spread for even coverage

They store gypsum outside

  • Exposed to weather rain/freeze that affects how the gypsum spreads
  • Swells as moisture adds weight to pile changing moisture percentage of product

We offer less compaction

  • No heavy loader or semi trailers
  • Lightweight conveyor
  • Floater moves faster across the field

Owners are directly involved

  • Operate the spreader
  • Meet with farmers and land owners
