Granular Humic Acids for Fields and Gardens
Granular Humic Acids for Fields and Gardens
Granular Humic Acids is a highly concentrated source of humic substances ideal for use on fields, turf, and vegetable gardens. Carefully mined from one of the world's richest deposits, it is derived from the ancient remains of decomposed organic plant materials and may increase micronutrient uptake by plants. Naturally occurring, unaltered oxidized lignite, crushed, screened and graded to a particle size of 1-3 mm.
For vegetable gardens and flower beds, use 1-2 lbs per 100 sq ft and thoroughly mix into the soil. Containers and potting mixes use 2 Tbsp/gallon of soil or 1-2 lbs/cu yd for new plantings and soil mixes; 1-2 tsp/gallon applied every 6-8 weeks for established plants. Lawns and turf use 10 lbs/1000 sq ft in spring and fall. Row crops/acreage use 75-150 lbs/acre, either in early spring - pre-plant - or in the fall - post-harvest. 50% humic acids derived from leonardite.

from 74 reviewsGreat product and delivery
Really nice soil and awesome service
Never used because I ordered the wrong Water Filter. Mike was very helpful with the return and refund. Excellent Customer Service.
Great service. Soil is what I wanted and it off loaded exactly where I asked.
Plants are doing really well with this soil. Deep and rich looking soil, plants seem really happy. Much more cost effective (and no plastic bag waste) compared to buying bags of soil mix from a store.
Thank you for shipping so soon. Great service
The quality of the craftsmanship is superb! My formula one fan absolutely loves it!!!!
Worked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
