The principle of resource conservation of the technological process of producing liquid-waste biosubstances at all stages
of realization of the technology is substantiated. Zero waste of the technology based on investigating the composition of
by-products and determination of the method of converting them into a marketable product and purposes of use is proved. 相似文献

Tissues of Angiospermae (deciduous arborous and herbaceous plants) were found to take part in the formation of humus in the agrogray soils. The proportions of lignic phenol contents between the soils did not change neither upon their plowing, no their drainage. Within the catenas studied, the maximal accumulation of phenol compounds takes place in the soils of the mesodepressions with long-term reduction conditions and in the soils of the microdepressions with spring perched water on two levels. In the Fe-Mn nodules of the agrogray soils, lignin of higher plants was found. Its fractional composition was correlated with the predominant vegetation. With the increasing size of the nodules, the amount of products of lignin oxidation in the nodules decreased due to its mineralization. Drainage caused a deep transformation of lignin in the Fe-Mn nodules, especially in the coarse fractions of concretions. The mineralization of lignin aromatic compounds under aerobic conditions was accompanied by the significant increase in the share of phenol acids. 相似文献

The complex effect of multipurpose compost (MPC) on the system soil-associative microflora-plant, increasing the numbers of
soil microorganisms, their enzymatic activity, and NPK content and promoting an increase of celery yield by 1.5–2 times, is
revealed. In this case, the content of nitrates in organs is within the limits of the maximum allow concentration. 相似文献
