Relationship between soil water content and crop yield under sahelian climate conditions: case study of Tougou experimental site in Burkina Faso
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 2017, Vol 13, Issue 10
Abstract
This study aims at assessing the relationship between soil water stock and the yield of agricultural practices in Tougou catchment located in northern Burkina Faso. It is a region that has experienced a significant and continuous degradation of its natural resources, especially soils, due to the climate variability and the rapid increase of the population. Areas allocated to subsistence agriculture are increasing at the expense of pastoral land. This degradation causes a change in processes and mechanisms that control ecological systems. In order to provide solutions to this issue, some agricultural practices have been implemented to improve crop yield. This is particularly the case of traditional techniques:za, stony line and half-moon, which can significantly improve the soil infiltration capacity and yield. Daily monitoring of soil moisture and pressure in experimental plots based on these agricultural practices show that half-moon and Za¯ provided good yield with 2180kg / ha and 1070 kg / ha respectively compared to that of the control plot with about 480 kg/ha. These important yields are due in large part to the improvement of the retention capacity of these soils, thus giving to crops the necessary water need for their development even in drought periods

Similarity in Analytic Behavior Intermediate Radial States of the Hydrogen Atom & Production of Radionuclides and Gamma Decay
The purpose of this paper is to show that analytic behavior of ground and intermediate states of the Hydrogen atom is similar to Gamma decay in molybdenum-99 (99mTc → 99Tc + γ).
Analysis of flow of polar and non polar incompressible ferrofluids
In this paper, flow between two parallel plates is analyzed for both polar and non polar ferrofluids. Velocity is obtained without pressure gradient for polar fluid and with pressure gradient for non polar fluid. The sol...
