Document Summary

Outline: a nutritional network: every organism is an open system linked to its environment by a continuous exchange of energy and materials. In fact, soil, water, and air all contribute to plant growth: plants extract mineral nutrients from the soil. About 95% of the dry weight of a plant consists of organic molecules. Plants require nine macronutrients and at least eight micronutrients: plants can be grown in hydroponic culture to determine which mineral elements are actually essential nutrients, plants are grown in solutions of various minerals in known concentrations. In a trial in relatively unproductive seas between. Concept 37. 2 soil quality is a major determinant of plant distribution and growth. Soil conservation is one step toward sustainable agriculture. In natural ecosystems, mineral nutrients are recycled by the decomposition of dead organic material. In contrast, when we harvest a crop, we remove essential elements.
