Mineral nutrition is thought to be the key process leading to the evolution of botanical carnivory. This chapter reviews the current understanding of ecophysiological processes associated with mineral nutrition of terrestrial carnivorous plants, with most attention to papers published since 1990 and to integrative studies of Nepenthes. It compares various characteristics of mineral nutrition of terrestrial carnivorous plants under both field and greenhouse conditions and emphasizes processes of the mineral nutrient economy of carnivorous plants: nutrient uptake efficiency from prey carcasses and reutilization of mineral nutrients from senesced shoots. The primary physiological effect of foliar capture of prey is the stimulation of nutrient uptake by roots. The chapter explains the concept of mineral cost of carnivory and highlights open questions associated with mineral nutrition of terrestrial carnivorous plants.

Aquatic Carnivorous Plants

About 60 species of the genera Aldrovanda and Utricularia are submersed aquatic or amphibious carnivorous plants. They all are strictly rootless and take up mineral nutrients for their growth from the ambient water and captured prey through their trap-bearing shoots. These species represent a specific ecophysiological group that are dissimilar in their principal morphological and physiological features from terrestrial carnivorous plants and from rooted and nonrooted aquatic noncarnivorous plants. I review the ecology of habitats of aquatic carnivorous plants; characteristics of their growth traits, photosynthesis, and mineral nutrition; regulation of the investment in carnivory in Utricularia; biophysical and physiological peculiarities of Utricularia traps; and turion ecophysiology. Open questions of the ecophysiology of aquatic carnivorous plants are discussed.

Установлено, что на пойменных почвах использование методов диагностики минерального питания растений моркови «по почве» и «по черешку» в фазу начала образования корнеплодов позволяет значительно (на 36–42%) снизить расход минеральных удобрений, обеспечивая урожайность моркови на уровне 70 т/га с долей стандартной продукции 78–81% без существенного изменения качества корнеплодов.It was found that in floodplain soils, the use of methods of diagnosis of mineral nutrition of carrot plants «on the soil» and «on the petiole» in the phase of the beginning of the formation of root crops can significantly (by 36–42%) reduce the consumption of mineral fertilizers, ensuring the yield of carrots at the level of 70 t/ha with a share of standard production of 78–81% without significantly changing the quality of root crops.

Spring wheat is the main grain crop. Stable production of high-quality wheat grain is the key to the country's food independence. Therefore, the study of the elements of growing spring wheat technology, aimed at increasing the productivity of crops, is important. The study of the interaction of plants and microorganisms depending on the level of mineral nutrition in crop planning is currently ofparticular relevance. The use of biological products, growth regulators improves the mineral nutrition of plants, increases productivity and its quality, and also provides savings in mineral fertilizers. In the upper Volga region, the main spring crops are wheat, barley and oats. To further increase them in the region, it is necessary to study the characteristics of the formation of yields and determine the most productive crops depending on the level of nutrition, biological products and growth regulators. The scientific article presents the results of the study of these drugs on the productivity of spring wheat. In field experiments, it was planned to get 30, 40 and 50 tons of grain per hectare. Fertilizers for the planned harvest were made taking into account the agrochemical properties of the soil. From biological products used Flavobacterin, which has a protective effect against diseases and improves product quality, from growth regulators used agrochemicals HUMATE + 7 (10 % liquid concentrate), which is characterized by high biological activity. The yield level was determined taking into account the average long-term moisture supply and qualitative assessment of arable land. The indicators of photosynthetic activity of crops, crop and its structure, quality characteristics of grain and economic efficiency of growing spring wheat in the upper Volga region are presented. As a result of researches the optimum level of mineral nutrition for wheat, the efficacy of agrochemical diazotroph and programming yields of spring wheat, determined the photosynthetic activity of crops and grain yield, calculated economic efficiency of the studied techniques and established the qualitative characteristics of the crop. The program for obtaining the planned wheat yields in the years of the experiments was completed by 68-91 %. Close to the planned the program was implemented using a biological product and growth regulator-74-91 %.

We review the current knowledge of trap anatomy of carnivorous plants, with a focus on the diversity and structure of the glands that are used to attract, capture, kill and digest their prey and finally to absorb nutrients from carcasses of prey. These glands have diverse forms. Regardless of their structure and origin, they have the same functional units, but there are differences in subcellular mechanisms and adaptations for carnivory. We propose a new type of carnivorous plant trap—a ‘fecal traps—which has unique physiology, morphology, and anatomy for attracting the animals that are the source of excrement and also to retain and use it.

Prey Attraction

The ability to attract prey has long been considered a universal trait of carnivorous plants. We review studies from the past 25 years that have investigated the mechanisms by which carnivorous plants attract prey to their traps. Potential attractants include nectar, visual, olfactory, and acoustic cues. Each of these has been well documented to be effective in various species, but prey attraction is not ubiquitous among carnivorous plants. Directions for future research, especially in native habitats in the field, include: the qualitative and quantitative analysis of visual cues, volatiles, and nectar; temporal changes in attractants; synergistic action of combinations of attractants; the cost of attractants; and responses to putative attractants in electroantennograms and insect behavioral tests.
