Nitrogen nutrition is the foundation of crop productivity. Proper management of nitrogen metabolism directly influences not only yield and product quality, but also the ecological state of agroecosystems. For agronomists and plant production specialists, understanding plant nutrition physiology and agrochemical diagnostic methods is a prerequisite for developing effective fertilizer application systems that balance plant requirements with the minimization of risks associated with excess nitrate accumulation.
This selection presents materials covering both the theoretical foundations of domestic agrochemistry, established by the works of D.N. Pryanishnikov and K.K. Gedroyts, and the applied aspects of working with various crops. Readers will find information on the specific nutritional needs of sugar beet, fruit, and flower crops, and will learn about modern methods for determining plant nutrient requirements and the rules for the rational use of mineral fertilizers. The articles also address the impact of agrochemical practices on the environment and human health, offering a comprehensive perspective on organizing the nutrition of agricultural crops in modern conditions.
Agrochemistry For students
The article discloses the agrochemical requirements of sugar beet regarding soil structure, density, and acidity. Data on the removal of primary nutrients and their effect on harvest quality are also presented.
Agrochemistry For students
The article examines the process of forming the domestic agrochemical school and creating the production base for fertilizers in the first half of the 20th century. The reader will learn about the scale of the first field trials and the evolution of specialized scientific journals
Agrochemistry For students
Nitrogen fertilizer is critical for yield; however, its excess leads to nitrate accumulation in produce. The article examines factors of nitrogen migration in soil, health risks, and maximum permissible intake levels
Agrochemistry For students
Rational use of fertilizers allows for reducing farm financial losses and preventing environmental pollution. The article examines methods of precise nutrient distribution and technologies for increasing nitrogen fertilizer efficiency.
Agrochemistry For students
The article examines the features of assessing the nutritional value of greenhouse soil and calculating fertilizer doses, taking into account the type of substrate and laboratory analysis methods. You will learn about the differences in approaches to determining available nutrients for key floral crops
Agrochemistry For students
The article describes the principles of mineral and organic nutrition of fruit trees. You will learn how to consider the type of root system and plant development phases for effective fertilizer application
Agrochemistry For students
Rational fertilizer application requires accurate calculation of nutritional doses based on the biological needs of the crop and the availability of elements in the soil. The article examines formulas for calculating nutrient uptake and methods for diagnosing the state of crops to improve the efficiency of top dressing
Agrochemistry For students
The article is dedicated to the scientific legacy of Dmitry Pryanishnikov, whose research in nitrogen metabolism and plant nutrition became the foundation for modern agrochemical practice and laboratory soil diagnostic methods
Planting and propagation For agronomists
The ability of plants to restore organs depends on genetics, the age of the mother plant, and environmental conditions. Understanding these patterns helps agronomists to effectively manage the rooting process and increase the yield of high-quality nursery plants.
Nutrition and fertilizers For gardeners
Fruit quality and market appeal depend on the concentration of sugars, vitamins, and micronutrients. The article presents a detailed biochemical profile of apples and examines the medicinal properties of pears
Pruning and training For gardeners
Reducing the canopy height to 2.5–3 meters improves tree light exposure and facilitates maintenance. The article discusses the rules for pruning the leader and integrated methods for controlling water sprouts
