Frequently Asked Questions

What is N-Ext Humic12 and how does it benefit your lawn?
N-Ext Humic12™ is a liquid humic acid bio-stimulant containing 12% humic acid. It helps make naturally available nutrients more accessible to turfgrass roots and can support root growth, chlorophyll content, nutrient uptake, soil structure, water retention, and overall plant quality.

How do you apply Humic12 to a lawn?
For backpack or pump sprayers, mix 6 ounces of Humic12 per gallon of water and apply evenly across 1,000 square feet of lawn. For hose-end sprayers, add 12 oz in the sprayer, fill the rest of the bottle with water and spray evenly across 2,000 sq ft. Water the product into the soil within 24 hours using approximately ¼ inch of rainfall or irrigation. Always follow the product label for complete application instructions.

How often should you apply N-Ext Humic12?
Humic12 can be applied every 30 to 45 days during the growing season. It can be used as part of a regular fertilizer and soil health program. Humic12 may be applied on its own or alongside compatible lawn-care products, including granular fertilizers and other N-Ext products. Always check product labels before combining applications.

Can Humic12 be used on all grass types?
Yes! Humic12 can be used on common cool-season grasses, including Kentucky bluegrass, turf-type tall fescue, and perennial ryegrass. It can also be applied to warm-season grasses such as Bermuda, St. Augustine, zoysia, centipede, and Bahia.
