What is Hi-Nitrogen Kelp-Humic Blend 32-0-0?

GS Plant Foods Hi-Nitrogen Kelp-Humic Blend 32-0-0 is a professional-grade, eco-friendly liquid fertilizer designed to correct nitrogen deficiencies and promote rapid greening. Unlike standard synthetic fertilizers, this formula combines three forms of immediate-release nitrogen with organic kelp and humic acid to support both instant plant growth and long-term soil health. It is ideal for all grass types, gardens, and hydroponic systems.

Key Ingredients & Active Properties

  • 32% Nitrogen (Three Forms): Provides highly soluble, easily absorbed nitrogen to fuel rapid leaf growth, resulting in dense, vibrant turf and foliage.

  • Organic Kelp: Delivers essential micronutrients, botanical extracts, and enzymes that enhance root vigor and increase plant resistance to environmental stress.

  • Humic Acid: Acts as a soil conditioner to improve soil structure, increase beneficial microbial activity, and unlock trapped nutrients for better root absorption.

Primary Benefits

  • Rapid Green-Up & Recovery: Visibly transforms dull, thinning, or yellowing grass into vibrant turf within 3 to 7 days.

  • Enhanced Nutrient Efficiency: The combination of kelp and humic acid maximizes nitrogen uptake, reducing fertilizer waste and preventing soil depletion.

  • Eco-Safe & Non-Toxic: Formulated with biodegradable, organic components that minimize environmental runoff, protecting local waterways.

  • No-Burn Guarantee: The balanced liquid formula ensures completely safe application with no risk of root or leaf scorch when used according to instructions.

  • Versatile Application: Safe and effective for all lawn varieties (including Bermuda, Kentucky Bluegrass, and St. Augustine), as well as vegetables, flowers, trees, ornamentals, and hydroponic setups.

Application Guide & Best Practices

  • Coverage Area: 1 quart of concentrate treats upwards of 3,000 square feet.
  • Application Method: Dilute according to package instructions. Apply evenly across the target area using a standard hose-end sprayer or pump sprayer.
  • Optimal Timing: Apply during the cooler hours of the day (early morning or late evening) to maximize foliar absorption and prevent evaporation.
  • Post-Application: Lightly irrigate the treated area immediately after application to water the nutrients into the root zone and prevent runoff.
  • Compatibility: Can be seamlessly mixed with other GS Plant Foods products—such as Root Ruckus, Liquid Kelp, and Cal-Mag Extreme—to further amplify nutrient uptake.

What Our Customers Are Saying

Thank you so much for Orchid Love. I bought mine on Amazon.com. I have been using it for the last five months. My orchids haven't looked better. Then I discovered a secret using your Orchid food. I have been dripping it down the old spikes of my 14 orchids not in flower for the last month. Now I have 5 of my orchids sending up new spikes that should be blooming around Christmas and 3 shooting secondary spikes off the old spikes. Even my other house plants love it. Thank you so much.

I received this product in a very timely manner. After the first application this seems to be working on my fall garden in zone 7. The lettuce, cauliflower, and broccoli all responded to a foliar spray of 1 Tbsp mixed in a half gallon of water. I also applied it to my tomato plants that had slowed down due to the colder weather and was surprised to see all of the plants start setting new blooms and fruit. I was at the point of actually pulling the tomato plants out for the year but look to maybe get a few more tomato's off each plant now!

Hi, just received your kelp and humic acid per Amazon.I scoped them at 40 and 100x shortly after opening and could not believe the diversity compared to a competitor's similar products.I provide the most thorough organic lawn/soil treatments in the Gainesville Fl area, and looking forward to continuing business."Thanks for your product

— Chad Freeman

So far, my plants and microgreens seem to respond well--new growth and deeper color--to the spray I mixed with water and store in the refrigerator.
My only complaint is that the bottle could be designed better so that the liquid doesn't drip everywhere and get a little messy even when using a funnel to catch extra liquid.
It smells strong & stains, so prepare your mixture outside or on a plastic covered table.

FAQs

Please read our FAQs page to find out more.

Why do organic fertilizers like yours have lower NPK values than synthetic fertilizers?

Synthetic fertilizers artificially spike NPK levels far beyond natural amounts, much like vitamin pills overload the body with nutrients it can’t fully absorb. Organic fertilizers, however, workwithnature—enhancing plants’ ability to uptake nutrients efficiently without excess runoff. This means lower NPK numbers deliverhigher effectivenesswhile protecting ecosystems from pollution caused by synthetic waste.

How should I store your products to maximize shelf life?

Store products in a cool, dry place away from direct sunlight and extreme temperatures. Ensure lids are tightly sealed after use. While most formulas have an indefinite shelf life, always mix only what you need for immediate use to maintain potency.

Do I need to water my lawn after applying your liquid fertilizers?

No watering is required! Our liquid formulas absorb quickly into the soil. For best results, apply early in the morning to allow 2-3 hours of soaking time before rain or irrigation. This ensures maximum nutrient retention without runoff.

Is it safe to harvest vegetables right after using your products?

Yes! Most of our products have a zero-harvest interval, meaning you can pick produce immediately. However, we recommend waiting 2-3 days after application for optimal nutrient absorption and flavor development.

How do organic fertilizers reduce environmental harm compared to synthetics?

Synthetic fertilizers overload plants with nutrients they can’t fully absorb, leading to harmful runoff that pollutes waterways. Organic formulas, like ours, mimic nature—delivering balanced, bioavailable nutrients that plants use efficiently. Think of it as feeding your garden a wholesome meal instead of forcing it to “overeat” synthetic additives.
