Soluble Amino Acid Nitrogen derived from soybean meal is a powdered product that can be dissolved in water and used as a high-nitrogen liquid feed.

It's our top choice for drenching or foliar feeding nitrogen. While it doesn't contain other nutrients in the same concentrations as liquid fish, it's much higher in nitrogen.

We suggest applying it in small quantities in liquid feeds through the entire season when nitrogen is needed.

When plants uptake amino acid nitrogen instead of ammonium or nitrate, there are multiple metabolic effects that are preferrable to inorganic nitrogen.
