Optimization Of Plant Development In Case Of Soil Salinization

Аннотация

This article discusses the improvement of the development of biotests in saline soils with the addition of zeolite, phosphogypsum, organic fertilizers. The development of biotests on seawater with a concentration of 1-10 g / l improved when humates, KNO3, and water extracts from crop residues were added to the water. A decrease in the salinity of the upper soil layer is shown when an interlayer with large pores from high moor peat is created at a depth of 25 cm.

INTRODUCTION countries.The study methodology consisted of assessing soil properties by conventional Comparative dynamics of soils light chestnut saline soils, red sulfate soils, saline brown semidesert soils, saline soils of Asian methods, assessing soil salinity [4]. In model experiments, the development of biotests The US A Journals Volume 03 Issue 02-2021 24 The American Journal of Agriculture and Boimedical Engineering IMPACT FACTOR (ISSN – 2689-1018) 2021: 5. 554 Published: February 28, 2021| Pages: 24-29 Doi: https://doi.org/10.37547/tajabe/Volume03Issue02-05 OCLC - 1121105746 was assessed when zeolite, phosphogypsum solubility of their precipitation, the processes [4], and organic fertilizers [9] were introduced of ion exchange and complexation and does into the soil. The effect on the development of not fully characterize their content in the solid biotests of adding 5-10 g / l of stimulants, N, P, phase of soils. For a more correct assessment K to sea water was studied [8, 9]. of soil salinity, it is necessary to determine the kinetics of their transition from soil to In field conditions, the effect of watering soils solution, the depositing ability in relation to with a mixture of sea, rain and river water on them, the content of positively and negatively the yield of rice on acidic sulphate soils was charged complex compounds, associates. assessed [8]. Agroecological assessment of soil salinization THE MAIN FINDINGS AND RESULTS is characterized by additional processes and An increase in the yield of agricultural crops regimes occurring in landscape components. on saline soils is of great economic The experiments have shown the presence of importance. However, for different types of salt components in the form of complexes, salinity, individual groups of soils, associates, precipitates, absorbed by the solid recommendations for optimizing the situation phase by the type of ion exchange. Depending have not been developed. They vary on humidity, temperature, рСО2, composition depending on the hydrothermal conditions of of migrating (ascending, descending and the territory and differ for individual crops lateral flows) soil solutions, there is constant grown. The transformation processes of the competition between the transition of some salt regime in the soil-plant system have been cations and anions from one state to another, insufficiently studied. The nature and degree as well as competing complexation, of soil salinity, as a rule, change in time and sedimentation, and competing processes of space [8]. ion exchange in soils and in metabolic The permissible indicators of soil salinity differ processes of plants and microflora [6, 7, 9, 11]. for different components of the landscape: The presented work proposes new methods soils, plants, water environment. They depend for regulating the combination of properties on the hydrothermal conditions of the of saline soils, the promising use of which has territory and change for individual been confirmed in our studies [4, 7, 8, 9]. geomorphological territories, microrelief in seasonal and long-term dynamics.
