Green House Agriculture
Green houses have become a preferred way of farming in many parts of the world. Farmers have turned away from depending on the natural environment because it is not very predictable as it was some time back. The environment has been tampered with and the farmers who rely on rain based agriculture expectations are not very promising. Global warming has contributed to poor harvests in agriculture. Most countries are not food sufficient.
Green houses are structures made to suit the crop growing conditions of the specific plant. The conditions work well protecting the crop from extreme weather conditions, pests and diseases. The structures are made from polythene papers, glass or other locally available materials.
Advantages of the green house farming outweigh the disadvantages. Planting is not based on seasons but it can be done any time all year round. The weather is regulated from inside the green house. Time spent working in the green house is less. In this type of farming the space used is not much thus little time used working on the land. Labour requirement is minim ore because the land is not that big to ask for many people to work on it.
Pests and diseases can also be arrested without much strain because land being used is limited and enclosed fully. Crops grown in the green houses mature a bit faster than other crops because most of the factors are regulated physically to ensure maximum output. Sunlight passes through the polythene to warm the greenhouse and facilitate quick growth.
Green houses are a sure way of providing food security as long as the farming is practiced properly to avert the problem of convective cooling commonly known as green house effect. People should be encouraged to practice it in an environment friendly way to avoid excess green house gases.
