Plant nutrition is a fundamental discipline combining the physiological processes of element uptake, soil science, and agrochemistry. Understanding the mechanisms of nutrient absorption through the soil solution, the role of the soil adsorption complex, and the influence of light and water regime allows both the agronomist and the gardener to take a well-grounded approach to managing crop growth. Knowledge of the classification of mineral elements, the role of secondary nutrients such as sulfur, and the mechanisms of humic acid action is key to increasing yield and plant adaptability to environmental stress factors.
This selection presents materials covering both the theoretical foundations of the science and practical research methods. The reader will become familiar with the history of the development of agrochemistry through the works of D.N. Pryanishnikov, K.K. Gedroyts, and K.A. Timiryazev, and will trace the evolution of concepts regarding photosynthesis and the humus theory of nutrition. The articles detail modern approaches to the study of mineral nutrition, including flow culture and split-root nutrition methods. The proposed block of materials will help systematize knowledge about the interaction of soil, fertilizer, and the biological characteristics of plants for effective agronomic practice.
