Organic foods are the new craze amongst today 's generation of environmentally conscious. Around the world the safety of food is more and more questionable. This led to the world 's population gradually turning to organic farming and products to fuel themselves. Currently, in the United States, much of the intellectual and health conscious populace invest their time and money into finding reliable organic food options. Organic markets are establishing themselves within numerous U.S. cities, and in which makes it easier for consumers to buy such foods.
It helps to enrich and regenerate the soil for better growth and development of the plants. It also helps the soil to retain water and nutrients better to minimise irrigation and fertilisation in areas with compost. This helps to reduce the cost for fertilisers or irrigation systems in farms/gardens and balances a tight budget. In addition, no chemical fertilisers will be used because leaching of such components to surrounding environment can be harmful to any using the surrounding water bodies. Without the use of chemical fertilisers, fruits and vegetables can be grown organically.
These 3 elements are provided to the plant in the form of fertilizers. With every harvest, the soil loses its nutrition and thus, the quality of the yield is also compromised. Fertilizers restore these nutrients back to the soil for the plants. Fertilizers of different kinds have been in use since a few centuries now. Earlier, farmers used organic fertilizers by mixing manure (plant and animal waste) in the soil
Organic minerals suh as nitrogen, phosphorus and potassium with symbiotic relation with fungi are available only in soil and soil organisms. Therefore, farmers need to ensure that crop roation and green manure help in providing nitrogen through legumes. Crop residues can be ploughed back to the soil generating potential orgnic fertilizers. Mixed farms with livestock and crops serve as ley farms. In this, the land gathers ferrtility through growth of nitrogen-fixing forage grasses suh as white clover and cash crops or cereals.
However the soil needs to have additional nutrients for successful plant grow. These can be provided by adding earthworms or compost. Earthworms and compost are both natural; they can both be used by the rural population as alternatives to provide nutrition to the soil and produce healthy crops and they are affordable. Spinach is a one of the few healthiest vegetables containing 20 measurable nutrients (Livingstone contributor, 2012). It has a very short development time and can be grown twice a year.
However it is sometime considered that the soil health is depends on biological activities held in the soil. There are few controversies about role of soil in plant growth and yield, as few belifs on its direct effect on plant growth and yield, while rest consider that it mere provide physical support and the growth and yield are the result of non-soil components, such as fertilizer and pesticide. Soil organisms contributes significantly in soil health through various ways such as, humus formation, decomposing dead plant and animal residues, enrichment of soil organic matter, etc. They produces carbon dioxide in soil to be dissolved in water and further converted in carbolic acid, which breakdowns insoluble rock minerals (Edwards et al. nd.).
Additionally, it improves the soil's quality and enhances its management by directly or indirectly promoting crop rotation, plant conservation, waste recycling and biological pest control. EM products create an antioxidant effect which enhances the immune system of plants and
What Is Nitrogen Fertilizer? Nitrogen is a major nutrient needed by all plants to grow. Although nitrogen exists abundantly in the atmosphere, relatively some plants are able to convert atmospheric nitrogen to a form they are able to use. Typically, nitrogen is used as commercial fertilizer supplement for depleted soil. Fertilizers are classified as “organic" fertilizers, which are naturally occurring substances such as manure, and "inorganic" fertilizers, which are manufactured through a chemical process.
