Amelioration of salt affected soils in rice paddy system by application of organic and inorganic amendments
Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...
متن کاملManagement of Salt-affected Soils for Sugarcane Production
To evaluate the effect of gypsum and manure on the yield and quality of sugarcane and properties of sodic soils, an experiment was conducted on farmer’s field at Dosehra area, District Charsadda during Kharif 2004. Ten treatments comprised of control (T1), gypsum @ 25 % of the soil requirement (T2), gypsum @ 50 % (T3), gypsum @ 75 % (T4), gypsum @ 100 % (T5), farm yard manure (FYM) @ 20 tons ha...
متن کاملRESEARCH, REVIEWS, PRACTICES, POLICY AND TECHNOLOGY Crop Response in Salt-Affected Soils
Salt-affected soils, those on which plant growth is limited by an excess of salts, are of three types: (i) saline soils in which electrical conductivity is > 4 dSm 1; (ii) sodic soils in which the exchangeable sodium percentage (ESP) is > 15; and (iii) saline-sodic in which the electrical conductivity (EC) is > 4 dSm 1 and ESP is > 15. Salt-affected soils are most common in aridic moisture regi...
متن کاملEffectiveness of spectral data reduction in detection of salt-affected soils in a small study area
Data reduction is used to aggregate or amalgamate the large data sets into smaller and manageable information pieces in order to fast and accurate classification of different attributes. However, excessive spatial or spectral data reduction may result in losing or masking important radiometric information. Therefore, we conducted this research to evaluate the effectiveness of the different...
متن کاملChemical Amelioration of Expansive Soils
Expansive soils swell when they absorb water and shrink when water evaporates from them. Hence, lightly loaded civil engineering structures founded in these soils are subjected to severe distress. Therefore, there is a need to ameliorate or improve these swelling soils through some innovative methods. This paper discusses chemical stabilisation of expansive soils, a technique in which chemical ...
