For over 40 years Agro-K has been a pioneer in the development of science-driven nutritional products for commercial agriculture

Agro-K products evolve from a comprehensive understanding of plant physiology.

This basis in the science of cellular-level plant development means our products are fine-tuned to help crops receive the nutrients they need precisely when that need peaks. Agro-K products are based in extensive knowledge of the interactions – positive or negative for plant development – of various chemistries within distinct crops and their soil environment. Data from decades of trials by leading universities, crop consultants, cooperators, and high-level producers have proven the sound science, efficacy, and value of Agro-K technologies for improving soils and for the rapid-uptake and bio-availability of nutrients.

By using the Agro-K plant physiology-based system for full-season nutrition, producers can achieve faster, more profitable payback from the living investment their plants and trees represent.

Agro-K soil conditioning and foliar plant nutrition technologies can assure that crops are growing in balanced, complex microbial soils and then receive the minerals needed for more robust root growth, more effective leaf area development, and stronger stalks or trunks to support more efficient vascular systems. These are the foundations for more effective nutrient uptake, photosynthesis, and translocation of minerals, water, and other building blocks of healthy plants. These plants – whether row crops, vegetables, tree fruit, nuts, or vines – are better able to tolerate the inevitable stresses of the growing season to produce more abundant, higher-quality harvests.

In any crop, the Agro-K systemic, season-long approach to nutrient enrichment can help producers meet their objectives – longer/thicker roots, more uniform stands, transplant hardiness, earliness, disease resistance, faster bearing, long-term orchard and field sustainability, improved fruit set, desired fruit structure, profitable sizing, great texture with more flavor, the right color, more dense meats, better pack-out and travel, longer shelf-life, greater consumer confidence, leading to more retailer confidence/loyalty. Whatever the combination a producer, packer, retailer, or consumer may seek, Agro-K products are a key component of making that happen.
