During its existence the Department „Iand improvements and Phisica” carried out activities not only teaching, but alco scientific, contributing to the development of land improvement works in Moldova.
This report analyzes land issues in Sri
Lanka, which cannot be seen in isolation from the ethnic and
political conflict and, at the same time, even though land
conflict is often linked with the ethnic conflict in Sri
Lanka, a large number of land conflicts in the North and
Necessity of the increment of the milk and meat production along with other agricultural products has caused the need to engage in an intensive agricultural use of new land, including flood areas that have been drained through the construction of polder systems. A total number of protective systems, fencing drained land from the influx of surface water compose over 3,900 miles of dikes.
The objective of researches was approbation of concept of the recreational biogeosystem engineering by example of phosphogypsum recycling in soil upon simultaneously rotary ameliorative tillage in the soil layer from 30 to 60 cm.
Soil change at management of its dispersed system by means of three-tier and rotor-milling tillage is studied. After single soil-meliorative rotor-milling plowing the processed soil layer consists of small units homogeneous for the size. There are no morphological signs of a solonetz pedogenesis restoration.
The state of soil cover and pedogenic rock in the farm Raygorod of theVolgograd region was investigated. The plot had an area of 1000 ha. The aim of the study was to justify the suitability of the plot for irrigation and develop the measures for increasing soil fertility.
The paper considers the influence on chernozem soil properties after the autumn application of calcium chloride as an amendment at the rate of 2.4 t/ha. At the end of the first year of aftereffect the results of soil analyses have shown the influence on such indices as pH, alkalinity and content of chloride, exchangeable cations and carbonates.
Studied was the impact of phosphogypsum and phosphogypsum-containig amendments on the properties of ordinary chernozem degraded due to irrigation with mineralized water (1.7-2.0 g/l), as well as on the crop yield.
In the conditions of the Republic of Belarus there were presented theoretical statements and methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use. There were formulated the notion and tasks of improvement of the use of lands of agricultural organizations.
There are around 400,000 hectares of soils with heavy mechanical composition, and the greatest part of the production area is under crops. The long term soil tillage by conventional methods (using plough) and a large number of passages of mechanization in this type of soil causes a subarable waterproof layer, with a lot of negative consequences in a crop production.
Water erosion is the most important degradation process of the 10 degradation processes distinguished by the European Union. The impact of rain drops on the soil surface causes splash of soil particles
The influence of application of various soil ameliorants (lime, manure and phosphorus fertilizers) to increase fertility of extremely acid soil type Pseudogley was investigated. The greatest fertility increase of studied soil was obtained by combined use of lime, manure and complex NPK fertilizer.
