Effects of Agriculture on the Environment Introduction: Agriculture has changed dramatically‚ especially since the end of World War II. Food and fibre productivity rose due to new technologies‚ mechanization‚ increased chemical use‚ specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre. Humans‚ like all other species‚ exploit their surroundings for the resources they

metalloids in high amounts in the soil. Some of the major sources of these pollutants are mining‚ smelting‚ mellaurgical industries‚ sewage sludge treatment‚ fertilizers‚ warfare and military training‚ electronic industries etc. (Padmavathiamma and Li 2007). There are several ways to remediate the soil chemically‚ physically‚ or biologically. However‚ chemical and physical treatments may seem to affect the soil properties heavily‚ affect biodiversity‚ make soil less fertile for plant growth and can

Using Compost Composting upcycles organic kitchen ‚ yard and agro-industrial waste and manures into an extremely useful humus-like‚ soil end product‚ permitting the return of vital organic matter‚ nutrients‚ and particularly bacteria‚ that are vital to plant nutrition to the soil. Long used in subsistence farming and home gardening for creating garden-ready soil‚ composting is becoming increasingly important and better understood as a tool for reducing municipal and industrial solid waste‚ and

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

into the surrounding soil. The sides of the planting hole should be sloped. 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
