Diamond Grow® Organic Nitrogen is a form naturally sourced organic hydrolyzed proteins containing amino acids and plant origin hydrolyzed enzymes.

Adding Organic Nitrogen to your soil allows the microorganisms there to cleave the protein molecules into amino acids, then separate the amino acids to form ammonium ions, and, finally, nitrate ions.

Proteins are the building blocks of all plant life and they are formed by the sequence of amino acids. The addition of amino acids directly affects the physiology of plant activities resulting in proven increased quality and yield.

Organic Nitrogen contains Hydrolyzed proteins. Organic Nitrogen protein hydrolysate is suitable for all plant types as a foliar or soil application. For best results, Organic Nitrogen should be used as a part of a crop or turf management program.

Content Analysis

Importance of Organic Nitrogen

Amino Acid Role in Root Development

Plants partition nutrients and energy for growth to adapt to environmental conditions. Nitrogen, an element common in all types of Amino acids, plays an important role in growth distribution. When the plant is supplied with large amounts of Nitrogen, which is usually the case in chemical fertilization, the plants tend to decrease nitrogen uptake. This usually directs growth allocation for shoot growth with consequent decrease in root growth. Plants fed with high levels of nitrogen increase its shoot length but not the lateral length of its roots. Introduction of excess amount of nitrates from chemical fertilizer inhibits the flow of auxins. Auxins are plant hormones responsible for growth and has an essential role in root development. Plants with poor root system will survive if there is abundant supply of water. However, when plants are subjected to stress due to water scarcity, the under developed root system cannot hold enough water to sustain development. This is one of the reason why heavy use of chemical fertilizers decreases the tolerance of crops to drought.

Methionine, a type of amino acid plays an important role in the synthesis of auxins. Application of amino acid can improve elongation of roots and improve nutrient absorption. Cysteine, another type of amino acid, plays a vital role in the development of hairy roots. A study by has shown increase in secondary roots and morphological changes in maize root architecture after application of both plant based and meat-based amino acid from protein hydrolysates. A study by Walch Liu, et. al (2006) has shown convincing evidence that the amino acid L-glutamate can act as an external signaling molecule to trigger changes in the root development by increasing the plant's ability to compete with neighboring plants and resident soil microorganisms for local organic nitrogen in the soil.

When subjected to environmental stress, amino acids can help improve the root system of crops to improve its foraging mechanism. Plants adapt to stress by increased growth of lateral roots to help scavenge heterogeneously distributed nutrients in the soil.

Role of Amino Acids in Osmotic Regulation

Availability of water is a major factor affecting yield of many agricultural crops. Water scarcity limits cell expansion and reduces cell rigidity due to water loss. These cellular effects of water stress is manifested through restricted shoot and leaf growth.

Free amino acids are osmotically active substances that contribute in osmotic pressure adjustments during water scarcity stress, thus keeping the cell wall rigid and keep cells from shrinking due to dehydration. Externally sourced amino acids can help in regulating membrane permeability and ion uptake which is how amino acids mitigate drought or even salt stresses.

Amino Acids as Chelating Agent

Enhanced Nutrient Absorption:

Besides the Macro nutrients like Nitrogen, Potassium and Phosphorus, plants also need Micro nutrients like Iron, Calcium, Magnesium, Copper, Zinc and Manganese especially when subjected to environmental stress. Amino acids can act as chelating agents. Chelating agents can form several bonds with metal ions. Chelated nutrients has increased mobility and absorption in plants.

The Benefits of Amino Acids

Action of Amino Acids on the Stomata of Plants - Beyond external factors such as light, humidity and temperature, the stomata of the plant open and close with the help of internal factors including, you guessed it, amino acids. This opening and closing helps control the moisture balance within the plant, but maybe most importantly, it also helps with the facilitation of gasses like carbon dioxide, which is required for extreme continuous growth.

Amino Acids and Their Effect on Pollination and Fruit Formation - Amino acids help with the fertility of pollen and thus are essential for pollination. They increase pollen germination and the length of the pollinic tube, which improves fruit set, strengthens cell walls for longer shelf life and helps improve the ripening stage of fruits, benefiting flavor and terpene production.

Amino Acids and Stress Resistance: - Stress factors such as high temperatures, low humidity, frosts, pest attacks, hail storms or floods have a negative effect on plant metabolism with a corresponding reduction in crop quality and quantity. The application of amino acids before, during and after stressful conditions supplies the plants with components directly related to stress physiology and thus has both a preventative and recovering effect.

Amino Acids and Improved Photosynthesis - Amino acids are fundamental in chlorophyll production; chlorophyll being the driving force behind photosynthesis. Amino acids help to increase chlorophyll concentration in the plant, leading to a higher degree of photosynthesis, which in turn leads to even more available energy.

Usage Instructions

Directions for Use:
Add Organic Nitrogen slowly into a 3/4 full spray tank with agitators running until completely dissolved. Organic Nitrogen is compatible with most agricultural and turf products; however, a simple “Jar Test” is highly recommended prior to mixing large batches. When using a tank mix, add Organic Nitrogen first and then add additional products. Organic Nitrogen can be used for both foliar and soil applications. This product is recommended as a supplement to a well balanced fertilizer program, and will not supply all necessary nutrients required by the crop.

Mixing instructions:

  1. Mix 1 kg. Organic Nitrogen into 20 liters water.
  2. Agitate/dissolve Organic Nitrogen in water.
  3. Further dilute with 80 liters of water & apply liquid.
  4. Apply diluted Organic Nitrogen to soil in fall and early spring up to 4 applications per grow season.

*Use a minimum of 2.5 GALLONS (10 liters) of water per pound (0.45 kg) of Organic Nitrogen.


Agronomic Crops: Organic Nitrogen is safe to use on all crops. For new plantings, apply 2 to 9 pounds (1-4 kg) of Organic Nitrogen per acre. Begin applications at or just prior to planting and continue applications (4-5 applications per year).


Fall Fertilizer Applications:100-1,000 Ibs./acre
Spring Pre Plant:100-200 Ibs./acre
