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.

Yes, it does make sense. Fertilizers are nutrient combinations that plants require for growth. The three primary elements in fertilizers are nitrogen, phosphorus, and potassium, often combined in a blend called NPK. Phosphorus specifically provides energy for plants and helps improve their growth. Most commercial phosphate fertilizers are made using rock phosphate as the raw material. The manufacturing process typically begins with the production of phosphoric acid. In the past, ground phosphate was used as a phosphorus source for acidic soils, but nowadays, due to low phosphorus availability, rock phosphate is less commonly used in agriculture.

Yes, the statement you provided does make sense. It explains that fertilizers contain nutrients that are necessary for plants to grow, with nitrogen, phosphorus, and potassium being the primary nutrients. These three elements are often combined into an NPK blend. In the specific case of phosphorus, it provides energy for plants to thrive and promotes plant growth.

The statement also mentions that rock phosphate is the raw material used in the production of most commercial phosphate fertilizers. Phosphoric acid is produced as an intermediate step in the manufacturing process. Previously, ground phosphate was used to provide phosphorus for acid soils. However, due to low availability of phosphorus, the use of rock phosphate in agriculture has significantly decreased.
