Quality Fertilizer is the middle tier of the fertilizers that raise crop quality. Mixed into tilled soil before a seed sprouts, it gives the crop a much better chance of coming up silver or gold at harvest. Higher-quality crops sell for more, so a field treated with it earns noticeably more than bare soil. The recipe arrives late in the Farming skill, and Pierre's General Store sells it from the second year. For iridium-quality crops, only the top tier, Deluxe Fertilizer, will do.
The in-game description reads: Improves soil quality, increasing your chance to grow quality crops. Mix into tilled soil.
Recipe
Reaching Farming level 9 teaches the recipe. Crafting Sap with any one fish makes a pair of Quality Fertilizer. The fish can be anything at all, so the cheapest catch in the chest is the sensible choice. Saving a few low-value fish from each fishing trip keeps a steady supply ready for planting day.
There are several ways to get it without crafting. Pierre's General Store keeps it in stock from the second year onward. The Traveling Cart sometimes has some. A Bone Mill can produce it too. Mystery Boxes and Golden Mystery Boxes sometimes contain a handful, and one of the Community Center bundles rewards a large stack.
These are the ingredients one batch needs.

Use
The fertilizer goes on tilled soil, either before planting or after the seed is sown but before it sprouts. Once the first shoot shows, the chance has passed. Each tile holds only one fertilizer, so it cannot be combined with Speed-Gro or Retaining Soil on the same square.
The effect shows at harvest time. A crop grown in Quality Fertilizer is far more likely to come up silver or gold than one grown in plain soil. The chance climbs further as the Farming skill rises, so the same bag does more on a high-level farm. Quality Fertilizer never produces iridium crops. Those need Deluxe Fertilizer, which Qi's Walnut Room on Ginger Island sells.

Notes
Quality only pays when the crop is sold raw or used where quality matters. Kegs and Preserves Jars ignore the quality of what goes in. Crops meant for Wine or Jelly gain nothing from the fertilizer, so it is best saved for crops sold straight from the field.
It pairs well with sprinklers. An Enricher attached to a sprinkler holds a stack of fertilizer and spreads it automatically on new plantings within the sprinkler's reach. That saves placing each bag by hand across a large field.
Choosing between fertilizer types depends on the crop. A slow, valuable crop gains a lot from extra quality. A crop raced against the season may be better off with Speed-Gro instead, since a tile only takes one.
