Effects of conservation tillage on water supply and

Reduced tillage is a practise in which the soil is tilled to some extent but not completely inverted. Zero or Chemical Tillage In this approach, the land is not tilled at all. Because the total and available moisture storage capacities are linked to porosity, the particle sizes texture and the arrangement of particles structure are the critical factors. Organic matter, carbonate levels, and stone content also affect moisture storage. Sustainable approach to improve soil conditions. An unnecessary form of land degradation. Quick and easy way to improve moisture loss of soil. This study assesses the various methods employed in agro-ecological zones of Africa in enhancing soil conservation through no-tillage practices. A reduction of tilling or the adoption of no-till farming combined with plant residues on the field surface soil cover or mulch helps improve the soil texture. Perform tillage at right angles to the prevailing winds usually north and south with a west prevailing wind. Optimised tillage helps to conserve to soil moisture. The new crop is generally planted directly into the stubble of the previous crop. An assessment of the potential for soil-conserving production systems in various agro-ecological zones of Africa Conserving Natural Resources and Enhancing Food Security by Adapting No-Tillage. They are not a set of static rules. on the contrary, they encourage modifications in order to address local needs and circumstances after a cycle of learning, thought and discussion among all collaborators.

Description: Conserving spring moisture to allow seed germination is especially difficult with small seeded crops like canola and in dry, windy conditions. Moreover, the chemicals can cause considerable harm the environment. Contour farming involves aligning plant rows and tillage lines at right angles to the normal flow of runoff. Heavy vehicles can lead to soil compaction and reduce water infiltration by reducing the soil pore volume. Costs Besides the costs for herbicides, tillage adaption requires only little financial investment, but investment in know-how. This factsheet talks about soil compaction and the four key points to prevent it. Because the total and available moisture storage capacities are linked to porosity, the particle sizes texture and the arrangement of particles structure are the critical factors. The costs for reduce tillage are small, but in some cases costs for herbicides are consequently higher. Use of a packer or harrow to fill in and seal the ground during the tillage operation may be important. Less tilling, lesser tillage depth, or no tillage at all has directly positive effects on the agricultural site. Performance Easy to perform, but requires knowledge. It was hoped that the course would give the participants a firm foundation and would stimulate the beginning of programmes for sustainable agricultural production. Strip cropping is the farming of sloping land in alternate, contoured strips of inter-tilled row crops and close growing grasses or other ground cover crop , aligned at right angles to the direction of natural flow of runoff.
