Types of fertilizers
Plant nutrients can be provided by mineral, organic or organo-mineral fertilizers, as well as through natural processes such as biological nitrogen fixation or the weathering of soil minerals.
The fertilizer industry produces mineral or manufactured fertilizers. Nitrogen, phosphorous and potassium, or NPK, are the primary nutrients in manufactured fertilizers.
Plants absorb more nitrogen than any other element. Nitrogen is essential in the formation of protein, and protein makes up the tissues of most living things.
Phosphorous supports a plant’s ability to use and store energy, this includes the process of photosynthesis. In manufactured fertilizers, phosphorous comes from phosphate rock, which is mined from the ground in certain parts of the world.
Potassium helps plants resist disease and has an important role in increasing crop yields and quality. Potassium also protects the plant in cold or dry conditions, strengthening its root system.
A wide range of products supplying one or more essential mineral nutrients are available to farmers.
Growers can combine their fertilizer applications with plant biostimulants—a tool for sustainable agriculture.
Plant biostimulants are products that contain substances or micro-organisms that stimulate the natural processes of plants and soils that lead to benefits such as better nutrient uptake, more resistance to abiotic stress such as high temperatures, and improved yield and crop quality.

An Introduction to Biostimulants
What are plant biostimulants?
Plant biostimulants are products that contain substances and/or micro-organisms whose function when applied to plants or the rhizosphere is to stimulate natural processes independently of the product's nutrient content to henhance/benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, yield, and crop quality.
