By time of harvest, will your organic fields and crops be free of prohibited materials applications for at least 36 months?

Have you taken care to avoid using prohibited fertilizers and soil amendments in organic production?

When applying fertilizers and amendments, are you using only allowed inputs?

If you apply raw manure to a food crop in which the edible portion makes contact with the soil, do you wait at least 120 days after incorporation before beginning harvest?

If you apply raw manure to a food crop in which the edible portion does not contact the soil, do you wait at least 90 days after incorporation before harvest?

If you are applying composted manures to food crops and the time intervals between application and harvest are shorter than the 90-and 120-day requirements specified for raw manures, is the initial carbon:nitrogen ratio of the feedstock mixture between 25:1 and 40:1?

If an in-vessel or static aerated pile system is used to make the manurebased compost, is the temperature maintained between 131°F and 170°F for at least 3 days?

If a windrow composting system is used to make the manure-based compost, is the temperature maintained between 131°F and 170°F for at least 15 days and are the materials turned a minimum of five times?

If you are using potassium chloride (muriate of potash of KCl), or a formulated fertilizer that contains it, is it derived from a mined source?

If you are using potassium chloride (muriate of potash of KCl) fertilizer, is it applied in a manner that minimizes chloride accumulation in the soil?

If you are applying sodium nitrate as a fertilizer, are you limiting its use to no more than 20% of the cropís total nitrogen requirement?

Are you applying all fertilizers and amendments at rates and in ways that do not cause ground or surface water pollution?

Are all the fertilizers and amendments you use free of contamination by heavy metals and residues of prohibited substances?
