Plant nutrition

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.

Agrochemistry For students

Effective biofertilizers for increasing yield and soil fertility

The use of biologically active preparations allows for optimizing crop nutrition, reducing the need for mineral nitrogen, and improving soil structure. The article examines the mechanisms of action and practical specifics of applying popular biofertilizers in open and greenhouse soil.

Agrochemistry For students

The role and deficiency of sulfur in the mineral nutrition of agricultural crops

Sulfur is a critical nutrient, the reserves of which in soils are rapidly depleting due to the intensification of agriculture. The article examines the causes of sulfur deficiency, current methods for diagnosing soil availability, and the biological characteristics of this element's uptake by plants.

Agrochemistry For students

The effect of soil solution reaction on crop yield

Soil solution reaction determines plant nutrient conditions and directly influences their productivity. The article examines the mechanisms of pH impact on crops and presents optimal acidity values for major plant species

Agrochemistry For students

The contribution of Lawes, Sachs, and Knop to the development of agrochemistry

The article describes the key stages in the formation of agrochemistry through the lens of classic field studies and the development of the water culture method. You will learn how scientists identified the essential mineral nutrients for plants and laid the foundation for modern fertilizer production
