Agronomy Facts

  1. Soil Science
    • Soil is a mixture of mineral and organic particles, water, and air.
    • Soil texture refers to the proportion of sand, silt, and clay particles.
    • Soil pH affects nutrient availability and microbial activity.
  2. Crop Science
    • Photosynthesis is the process by which plants convert light energy into chemical energy.
    • C3 plants (e.g., wheat, rice) produce 3-phosphoglycerate (3-PGA) as the first product of photosynthesis.
    • C4 plants (e.g., maize, sugarcane) produce 4-carbon molecules as the first product of photosynthesis.
  3. Fertilizers and Nutrients
    • Nitrogen (N), phosphorus (P), and potassium (K) are the three main macronutrients for plant growth.
    • NPK ratio refers to the proportion of these nutrients in a fertilizer.
