Major Nutrients

Of the major nutrients, nitrogen (N) is often required in the greatest quantity by crops, primarily for vigor and yield. Nitrogen plays a key role in chlorophyll production and protein synthesis. Chlorophyll is the green plant pigment responsible for photosynthesis. When nitrogen is deficient, plants develop yellow or pale leaves and their growth is stunted.

Phosphorus (P), is...

Secondary Nutrients

Of the three secondary nutrients needed at lower levels than NPK, calcium (Ca) is perhaps the most important. Calcium strengthens cell walls, helping to reduce bruising and disease in fruit, salad and vegetable crops. This means that a good supply of calcium produces food crops that are less prone to damage and have a longer shelf life. Crops short in calcium will have growth disorders such as corky skin.

Fruit and vegetables containing higher levels of ....

Micronutrients

Micronutrients reinforce and supplement the strong plant growth and structures provided by major and secondary nutrients.

Most micronutrients influence growth.  For example, manganese (Mn), iron (Fe) and copper (Cu) all influence photosynthesis, the process whereby plants use sunlight for growth.
Iron deficiencies are ....

Crop Needs and Amino Micro Power®

Each crop needs a different range of nutrients at every critical stage of its development.

For example, nitrogen and phosphorous are often more critical at early stages of growth to fuel root and leaf development, whereas zinc and boron are important during flowering.

Cereal crops use nutrients for growth, progressively moving them from the roots, leaves and stems into the ear prior to the dying off and harvesting of the grain.

Tree crops have....
