Ferti

Ferti-Corn Steep is a water-soluble fertilizer, derived from non-GMO corn, that can be applied directly, or it can be mixed with other liquid fertilizers, growth promoters (seaweed) or dry fertilizer, whether it is sprayed, irrigated, foliar or applied through soil.

ISO 18645:2016 Fertilizers and soil conditioners

ISO 18645:2016 specifies the requirements for testing methods, sampling and preparation of test sample, marking and labelling, as well as package, transport, and storage of water soluble fertilizers.

Water Soluble Fertilizer

This standard specifies the definition, requirements, test methods, inspection rules, marking, packing, transport and storage of water soluble fertilizer.

Corn Fertilization

Table 1 lists specific amounts of each nutrient removed from the soil by corn stover and grain at a yield level of 150 bushels/acre. The nutrients taken up by the plants must be supplied either from soil reserves or by adding nutrients. A deficiency of any of these nutrients can reduce yields.

Technical Requirements for Corn Flour Fermented Water-Soluble Fertilizer

I. Material Preparation

1. Corn Flour: Select fresh, mold-free, and odorless corn flour to ensure quality.
2. Water: Use clean and pure water, avoiding contaminated or hazardous water sources.
3. Fermentation Agent: Choose suitable microbial starters such as yeast or rice koji (koji) based on specific needs.
4. Container: Use airtight ceramic jars or stainless steel containers suitable for fermentation.

II. Production Steps

1. Mix corn flour and water in a specific ratio, ensuring thorough blending.
2. Add an appropriate amount of fermentation agent and mix uniformly.
3. Transfer the mixture into the container and seal tightly.
4. Ferment at an optimal temperature for 1–2 days.
5. After fermentation, filter the corn flour solution to obtain the water-soluble fertilizer.

III. Technical Requirements

1. Corn Flour Selection: Ensure corn flour is fresh, mold-free, and free of off-odors.
2. Water Quality: Use clean water to avoid contamination.
3. Fermentation Agent: Opt for yeast, rice koji, or other microbial agents as needed.
4. Fermentation Time: Typically 1–2 days, adjusted according to temperature.
5. Temperature Control: Maintain fermentation temperatures between 20–30°C; extreme temperatures affect outcomes.
6. Environmental Control: Ensure a dry, well-ventilated environment to prevent contamination.
7. Filtration: Remove impurities by filtering the fermented solution.
8. Storage: Store the finished fertilizer in a cool, dry place, away from sunlight and heat.
9. Usage Guidelines: Dilute before application following recommended ratios.

IV. Precautions

1. Monitor fermentation to avoid over-fermentation and spoilage.
2. Maintain hygiene during production to prevent contamination.
3. Use the fertilizer promptly after fermentation to maintain quality.
4. Handle with care; avoid contact with skin or eyes.
5. Discard and consult professionals if the product develops abnormal odors or discoloration.

V. Application Range

Corn flour fermented water-soluble fertilizer is a high-quality organic nutrient suitable for various crops, including grains, cash crops, and fruit trees. It provides essential nutrients, enhances crop quality and yield, improves soil structure, increases fertility, and boosts water retention.

Note: Terms like "rice koji" (米曲) may require contextual explanation for non-specialist audiences. Adjustments can be made based on target reader familiarity with fermentation agents.
