1. General trends of changes in the biosphere -- 2. Food and drought problems -- The present spread of deserts and arid regions -- The soil cover of arid regions -- Soil formation in autonomous landscapes (without participation of groundwater) -- Soil-forming processes in the hydromorphic landscapes of arid regions -- Human activity and drought -- Land cultivation and increased frequency of dust storms -- Dry farming and the protection of soil against erosion (degradation) -- The improvement of soil structure and hydrophysical properties -- Bare fallow and moisture accumulation -- Field cultivation without turning the soil -- Erosion control -- Forest plantings to protect against erosion -- The problem of shifting sands and their stabilization -- Improved management of arid pastures -- 3. Irrigation and increased biological productivity -- Irrigation of soils in arid areas -- Types of irrigated areas -- Climate, evaporation, and irrigation -- The role of soil and groundwater salinity -- Geomorphological conditions and irrigation -- Effect of irrigation water on soils and landscapes -- Changes in the hydrophysical dynamics of soils -- Changes in the chemical and biochemical dynamics of soils -- Secondary salinization of soil -- Soda-salination -- Quality of irrigation water -- Indices of soil salinity and methods of reclamation -- Saline and nonsaline soils -- Seasonal salinization of soil and how to combat it -- Critical depth of mineralized groundwater and drainage -- Removal (leaching) of salts from soils -- Rice for soil desalinization -- Difficulties and efficiency of drainage -- Control of the water-salt balance in irrigation -- Data required for studying and forecasting the water-salt balance -- Required initial materials -- Flow sheet -- Determination of initial reserves of different salts in designated blocks (in soil-geomorphological reclamation units) -- Evaluation of the role of the irrigation network -- Evaluation of the effect of vegetational irrigation on the fields -- Evaluation of natural groundwater outflow at different levels -- Determination of the expenditure of groundwater by evaporation and transpiration -- Determination of the rate and time of rise of groundwater (without artificial drainage) -- Determination of the possible mineralization of groundwater and soil salinization |
