Full textIntegrated into international economic networks and produced in some countries of the South, cotton is more and more cultivated in the western parts of Burkina Faso where soils and weather conditions are favourable. After some field observations and interviews carried on with the farmers of Mouhoun, the area seems to be affected by dynamics mechanisms of water and wind erosion which are visible in the landscapes, active at various scales and variable according to the different topographical units. The cultivation of cotton has developed in traditional farming systems of savanna areas, these systems being based on moving farming and the pratice of fallowing land. However, the specific logics of cotton growing have gradually changed the traditional systems through the intensification and mechanization they involve, thus simultaneously causing a differenciation among farmers. As the modernization of technical practices is not always adapted to the local environments which are by nature vulnerable to erosion, the land is increasingly weakening and the damage process is made worse owing to overexploitation of resources and misuse of imported farming methods. Aware that the land is “getting tired” and eroding, the farmers in Mouhoun are spontaneously implementing erosion management, the latter being associated to national and international programmes for sustainable preservation of the environment

Full textSoil salinity extension in Northeast of Thailand is a huge problem for the farmers and the Thai authorities. It endangers both the agriculture and the environment, and is cause to almost irreversible. Soil degradation. Low fertility sandy soils were however reported long time before the salinity started to spread, and explained by the ferrolysis process. Both salinization and ferrolysis seem to be the important soil genesis processes forming the lowland soils. The first process leads to alkaline soils, whilst the second leads to acid soils. This study therefore focuses on the interactions between the two processes, namely sodication and ferrolysis, and particularly on the role of sodium and ferrous iron on clay weathering. It is driven in a paddy soil sequence in Phra Yun basin, Northeast of Thailand. This work was carried out in three steps. The first step is the study of clay tlocculationdispersion behaviour in sodium and ferrous iron electrolytes in the laboratory. The second step is the in situ characterization of the soil solution compositions, during rice cropping and rainy season. The third step is the description and analysis of the soil sequence. Finally, these different results are compared and conclusions are taken. The results show that the effect of ferrous iron on the tlocculation of clay is quite identical to calcium. The flocculated clays are well-crystallized kaolinite and dispersed clay is smectite and disordered or small kaolinite. A maximum ferrous iron concentration of 0. 67 mmol L-1 is necessary to flocculate the clays whatever the other cations in the electrolyte. Such a concentration is currently reached in rice-cropped soil solution, thus suggesting that rice cropping may prevent clays to disperse. The field soil solution monitoring shows that ferrous iron concentration increase upon reductive dissolution of oxides during rainy season, and other cations are leached due to heavy rainfalls and tlooding in rice fields. Both reductive dissolution and salt leaching are enhanced by rice cropping. The clays are likely to disperse in the non cropped and non saline profiles or leached surface horizons, and to flocculate in saline deep horizons or rice-cropped and reduced surface horizons. Thus rice cropping is likely to both enhance the conditions for the fust step of ferrolysis, and balance the dispersive effect of sodium by increasing the ferrous iron content of the soil solution. The description of the soil sequence shows that the soil clay and silt content increase from top to bottom of sequence and profiles. Many clay dispersion and clay precipitation features, such as clay cutans, appear in the horizons. Clays seem to mostly accumulate in the medium, compact horizons of the bottom part of the sequence. The soil and clay analyses agree with these observations. The mean particle size continuously decreases with depth and topography. Conversely, the reactivity of the clay increases, smectite being the major clay type down the sequence. All results agree to show that ferrolysis has a limited effect in forming these soils, though they belong to soil series that are typically considered as ferrolysed. The role of ferrolysis might thus be overestimated is assessed oruy by hydromorphic conditions and profiles wit low CEC and contrasting textures. The soils of the sequence form by clay and silt translocation, which is mostly controlled by sodium and ferrous iron content in the soil solution. Rice cropping has thus a great impact on soil forming

Full textThe thesis focuses on sandy soils of Northeast Thailand. A compact and resistant layer developed at low depth is a main constraint for agriculture. The thesis follows a sequence of studies that investigates (i) the physical properties of these soils in various situation natural or cultivated, (ii) the main mechanisms explaining the different physical states recorded and (iii) the research of methods for rehabilitation of damaged soils. Results highlighted the aeolian origin of the soils. This origin gives them a striking textural homogeneity and unique mechanical characteristics. Very sensitive to compaction, they collapse at low water content and under low mechanical pressure. Conventional tillage practices are not suitable as they induce structural instability. However alternative techniques as slotting or biological drilling are efficient
