does this make sense?

Fertilizers are combinations of nutrients that plants need to grow. The primary nutrients of fertilizers are three different elements which are nitrogen, phosphorus, and potassium. These elements are often combined into a NPK blend. Phosphorus in the fertilizers provides energy for plants to thrive. It improves its plant growth. Rock phosphate is the raw material used in the manufacture of most commercial phosphate fertilizers. . The manufactures of most phosphate fertilizers start with the production of phosphoric acid. In the past, ground phosphate was used as phosphorous for acid soils, but now, because of low availability of phosphorus, very little rock phosphate is used in agriculture.

Phosphorus in the fertilizers provides energy for plants to thrive. I found where you copied this, however, I assure you it is incorrect. Phosphorous provides for complex energy transport and conversion in plants. The sun provides the energy.

I wonder what is the purpose of the opening three sentences? The paragraph is about phosphorus in plants, and the sources of phosphorus fertilizer. Grammar is ok (except two periods on the fifth line), but the paragraph seems to need a theme sentence.
