The Big 3 - Nitrogen, Phosphorus, and Potassium (2)

It is the cultivated agricultural land of the earth that sustains human life and prosperity. Plants provide food, fibre, shelter, and many other benefits, and fertilisers play a key role in this process. Fertilisers are needed more than ever to increase the production of corn and keep people nourished and healthy.

  1. TheBig3-Nitrogen,Phosphorus,andPotassium It is the cultivated agricultural land of the earth that sustains human life and prosperity. Plants provide food, fibre, shelter, and many other benefits, and fertilisers play a key roleinthisprocess.Fertilisersareneededmorethanevertoincreasetheproductionof cornand keep people nourished andhealthy. Every growing plant needs 17 essential elements to reach its full genetic potential. Of these 17, 14 are absorbed by plants from soil and the remaining 3 are absorbed by air and water. Generations of soil science have given us knowledge of how to test soil for nutrients,howplantsabsorbthem,andhowtooptimallyexchangethosenutrientsafter harvest. Nitrogen,phosphorus,potassium,orNPKfertiliserarethe"bigthree"macronutrientsin commercial fertilisers. Each of these basic nutrients plays an important role in plant nutrition. Nitrogen is considered the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to ensure that plants are healthy during developmentandnutritiousafterharvest.Belowisapictureofnitrogen-deficientcorn.
