Agronomy
Agronomy is the science and practice of managing crops and soils to improve agricultural production and sustainability.
Soil fertility: Soil fertility is a soil’s capacity to supply plants with essential nutrients in available forms. Fertility management supplies nutrients while limiting losses and damage to soil.
Precision agriculture: Precision agriculture uses spatial data and technology to tailor farm management to variation within fields. It applies agronomic measurements to vary inputs where crops and soils differ.
Soil science: Soil science studies soil formation, properties, classification, and functions. Agronomy draws on soil science to diagnose field conditions and guide management.
Soil erosion: Soil erosion is the removal and transport of soil by water, wind, or other forces. Poorly matched field practices can accelerate the loss of fertile topsoil.
Jethro Tull: Jethro Tull was an English agricultural innovator who promoted horse-drawn seed drilling and intensive cultivation. His seed drill made crop establishment more precise and mechanized.
Crop rotation: Crop rotation is the planned sequence of different crops grown on the same field over time. Changing crops can disrupt pests, balance nutrient demands, and improve soil condition.
Conservation agriculture: Conservation agriculture combines minimal soil disturbance, soil cover, and crop diversification. It offers a management framework for protecting soil while producing crops.
Plant physiology: Plant physiology studies the functions and processes that sustain plant growth and development. Knowledge of plant responses explains how crops react to management and stress.
Nutrient pollution: Nutrient pollution is environmental harm caused by excess nitrogen or phosphorus entering air and water. Fertilizer management influences nutrient runoff, leaching, and emissions.
Justus von Liebig: Justus von Liebig was a German chemist whose work helped establish modern agricultural chemistry. His theories shaped scientific debate about plant nutrition and soil fertility.
