Phosphorus, like nitrogen, is a member of the pnictogen group and was the thirteenth element to be discovered and the first element that was chemically discovered by Hennig Brand in 1669. It is one of the three major essential elements needed by plants simply because of the amounts that are utilized by the plant. Phosphorus is the only element that was discovered through a disgusting process involving the concentration of urine.

Ferti-Facts: Nitrogen - A Change in Tradition


Daniel Rutherford discovered the existence of nitrogen by first depleting oxygen from air. He accomplished this by asphyxiating a mouse in a closed jar, burning a candle until it went out in the jar, and burning phosphorus until it would not burn. The remaining gas was passed through a carbon dioxide absorbing solution.     The remaining gas (which is now almost pure nitrogen gas) did not support the burning of a candle or life of a mouse. He referred to this gas as noxious or phlogisticated air (Phlogiston was a postulated element that was released from combustible bodies when burned).

As any farmer or agriculturalist knows, nitrogen is a critical food for any crop or plant in every growing condition. Tough growing conditions in particular demand Grower’s Secret organic nitrogen products, a readily available plant food source containing high levels of amino acids to increase growth and vitality of growing plants.


Microbial Weapons for Agricultural Production

During the early 20th century, soil microbiology and ecology studies led to the identification of many microorganisms that act as antagonists or hyperparasites of pathogens and insect pests. This was the origin of a popular research topic, biological control, the use of an organism or organisms to reduce disease (caused by plant pathogens) or damage (caused by insect pests). This often resulted in the release of several predators, parasitoids, and pathogens of insects and plants until the mid 1900’s. Many showed promise in field-scale inoculations, but few were developed commercially because of the rapid adoption of less expensive and more consistently performing chemical pesticides.
