What are the 3 ingredients in fertilizer? Understanding the Fertilizer Label These three numbers represent the primary nutrients (nitrogen(N) – phosphorus(P) – potassium(K)). This label, known as the fertilizer grade, is a national standard. A bag of 10-10-10 fertilizer contains 10 percent nitrogen, 10 percent phosphate and 10 percent potash. What are the two main […]

What are the characteristics of metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust.
