Company of the Week - Pacific Grading Service

Most
vegetable
and
melon
row crops
benefit
from density grading.

The
cut flower
and
garden flower
industries can boost yields from uniform growth.

Density grading separates seed by its weight instead of its size. This gives you the uniform seed performance you expect.

Pacific Grading Service uses small, air-forced gravity tables that allow for specific seed separation.

Heavier seed stays on the deck and moves to the high end of the table while lighter seed rises to the top and falls to the lower end

Since seed flows over the deck, internal machinery damage to the seed is nominal. Germination enhancing chemical treatments are not used with our grading procedure. This means there is no concern with drop in germination or limited shelf life.

Density grading deals with the weight of the seed, not the size, therefore, belt changing is not required.

Density grading has shown improvements in plant population and quicker emergence while reducing costs in both direct seeding and greenhouse transplanting environments.

Density grading seed is an effective, low risk, minimal loss process.

Density grading can be used as an effective substitute to priming for some types of seed, but Pacific Grading Service suggests using density grading in addition to priming to insure optimum uniform emergence.
