our land resources‚ has taken a heavy toll on our soils. What are the causes of this issue? e.g land degradation‚ salinity and overgrazing Firstly‚ land degradation is any change in the land that reduces its existing or potential productivity. It commonly occurs wherever the natural balance in the landscape is changed by human activity‚ through misuse or overuse. This is the result of land when using it beyond its capabilities. As we know‚ soil is a natural resource vital to the well-being of

food yield. Soil fertility maintenance is essential in achieving and maintaining high crop yields over a period of time. Fertilizer application has usually been the major means of supplying plant nutrients. Use of mineral fertilizers has proven to be more convenient than the use of organic fertilizers that have traditionally been used since pre- industrial age. The impact of increased use of mineral fertilizers has been high but the resulting soil physical degradation‚ and increased soil acidity level

The hole should be no deeper then the root ball or container to prevent the tree from settling or being planted too deeply. 2. Tree Preparations: For a container tree; remove the container. For a balled and bur lapped (B&B) tree‚ remove the rope around the trunk and loosen the burlap. If the root flare is not visible‚ gently remove soil from the top of the ball until the tree is again at proper soil level. On both types

an excellent medium for growing plants. The process of composting ensures the waste that is produced in the kitchens is not carelessly thrown and left to rot be a home for flies and give foul smell. It recycles the nutrients and returns them to the soil as nutrient. Apart from being clean‚ cheap‚ and safe‚ composting can significantly reduce the amount of disposable garbage. Compost pits not only produce the benefit of suitable degradation of waste but even:- Helps reduce the adverse effects of

Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and

St. Helens‚ a stratovolcano in western Washington‚ erupted. The eruption scoured the slopes of the volcano removing vegetation and soil from the vicinity of the mountain. 32 years after the eruption‚ vegetation has returned to the mountain. The author’s main interest in this field is the methods by which vascular plants re-establish themselves after cataclysmic‚ soil-removing volcanic eruptions‚ and if some plants are better suited than others to re-establishing on volcanic tephra and other eruptive

While thinking of these ideas to help improve my property I went back to the things I learned in the soil and agriculture chapters in my wonderful ecology class. I remembered how important finding out the pH of soil was. With this information one of my measures is to test the soil for the pH. By finding this out it can be adjusted‚ show if there is good availability to the plants foods‚ and is an important indicator of air pollutants. A second
