Fertilizers add nutrients in soil, that well influences growth of trees, vegetables, medicinal grasses, bushes and colours. Various kinds of fertilizers depend on your soil (alkaline, sandy, clay, stony and so on). Fertilizers as a whole are subdivided on organic and inorganic (or chemical fertilizers). Organic fertilizers are the most convenient form of fertilizer. They are safe and easily accessible. Manure, dung water, a peat moss, sea seaweed etc. good examples of organic fertilizers. Vegetative materials are called mulches, such as, hay, a peat moss, leaves, a grass, a bark, a wood chip, a peel of sunflower seeds - all it helps to protect the earth from change of temperature and add necessary nutrients. Kinds of fertilizers: - Green fertilizer are specially grown up plants for addition of nutritious and organic substances in soil. This kind of a crop is used for soil preparation before crops of grain crops. Roots of some green fertilizer sprout deeply in soil and lift nutrients which are not present at small grain crops. Siliculose grain crops well approach as green fertilizers because they add nitrogen in soil.
- Compost - leaves, plants and a waste of animals which are used as fertilizer here enter. Compost is stored in a crude kind to prolong activity of organisms which are in it.
- Peat - consists of plants and improves soil structure.
Advantages of organic fertilizers - Improvement of structure of soil.
- Keep humidity of soil.
- Allocate nitrogen slowly and consistently.
- Do not burn a plant, as some chemical fertilizers
Lacks of organic fertilizers - Often organic fertilizers, especially what contain animal and vegetative substances, are infected by pathogenic organisms.
- The structure of organic fertilizers is various, therefore is the diluted and incomplete source of nutrients in comparison with an inorganic kind of fertilizers.
Inorganic or chemical fertilizers, first of all, are received as a result of chemical compounds, such, as nitrate of ammonium, ammonium, phosphates and chloride potassium. Sodium nitrate, phosphate and limestone rocks are examples of inorganic fertilizers. Advantages of inorganic fertilizers - The correct quantity of the nitrogen which has been picked up in inorganic fertilizers, promotes growth of stalks and leaves.
- The phosphorus considerable quantity promotes growth of colours, improves growth of fruits, and improves health of roots and tubers.
- Potassium and the potash protein promotes development of stalks and leaves.
- Nitrogen release occurs fast rates.
- Sufficient source of nutrients.
Lacks of inorganic fertilizers - Inorganic fertilizers if they are used carelessly, can spoil your plants and deform quality of the earth with its subsequent poisoning.
- At use of inorganic fertilizers it is necessary to use a considerable quantity of water with a view of moisture preservation in soil.
