Welcome To PHD Maximum Crop


Your Source for Nutrients, Seed, and Improved Crop Production

Improving Plant & Crop Vitality Without Chemicals

At PHD MaximumCrop LLC, we recommend a combination of liquid Humic and Fulvic acids to repopulate the soil with beneficial microbes and to encourage the reactivation of the existing microbial population in the soil. Selecting a product which will add real long term value to the soil will enliven both the soil and the plant. PHD Maximum Crop LLC programs work below the soil surface, allowing the plant to grow a healthier roots and to receive more nutrition from nutrient processing microbes. Since our products contain a healthy balance of microorganisms, the root zone, compaction levels, and overall soil health will be considerably improved.
