Role of long-term pasture agroecosystems in the repro-duction of gross energy in the biosphere

Abstract

Based on a new method of energy assessment of meadow agroecosystems, data on the accumulation of gross energy by pasture ecosystems over a 76-year period were obtained. Quantitative indicators are given for the total production of gross energy and its distribution in the aboveground and underground mass of pasture phytocenoses, taking into account changes in the energy intensity of soil fertility.
