PrimAgro P

Phosphate Biofertilizer for Soil Conditioning and Plant Growth

PrimAgro P™ is a phosphate biofertilizer combining macronutrients, micronutrients, secondary nutrients and biologicals. With PrimAgro P, you not only restore essential phosphorus in your soil, but you also add other essential nutrients as well as beneficial bacteria. These substances all work together to build up the soil and optimize nutrient uptake and growth in plants.

Soil biology is an essential part of a healthy orchard, though it is often overlooked. Years of pesticides, fungicides and fertilizers which keep trees and vines healthy also damage the natural microbial activity in the soil. This makes natural processes, such as nitrogen fixation and the breakdown of organic matter more difficult. Restoring the soil biology helps these natural processes resume. 

PrimAgro P phosphate biofertilizer puts microbes back into the soil to help restore the nutrient profile. These microbes play important roles in the natural production and storage of macronutrients in the soil. This means the soil retains more nutrients naturally, reducing the chance of deficiencies and making more nutrients available to plants at all stages.

PrimAgro P is safe for trees, vines, and many other permanent crops. You can easily apply PrimAgro P with the processes you already use, including broadcast, topdress, fertigation, foliar, and more. PrimAgro P contains nitrogen, phosphorus, potassium, and sulfur in addition to essential soil microbes.  Allowing you to restore your orchard or vineyard’s soil while also providing essential nutrients to your plants.

Have us design a custom nutrition plan for you

An AgroLiquid nutrition plan is dependent on your location, climate, soil conditions, and goals with your crop. All of our tailored programs start with reviewing your soil samples with one of our expert agronomists. After our analysis, our team will provide you with a couple options that will help you meet your goals on a budget that won’t break the bank.

AgroLiquid Scientific Advancements

PrimAgro biological fertilizers were created to improve plant growth while restoring the soil. Two of our proprietary technologies, Nutriq Technology and PrimAgro biologicals, work collaboratively in our biological fertilizers to provide sustainable nutrients in environmentally friendly ways. The Nutriq Technology slowly releases nutrients to plants and provides a steady source of nourishment throughout the growing season. The PrimAgro biologicals support beneficial microbial growth, which prevents leaching and keeps the soil, water, and air cleaner.

Nutriq Technology

This bonds with your nutrients and creates a protective layer that makes up to 80% more of your nutrients available to plants. It sounds like magic, but it’s just science.
