COOP FERTILIZER USE AND EFFECT ON PLANT

The use of organic materials such as pile farmers have done for a long time, but its use in large numbers causing difficulty in sourcing the supply, transport and application. Organic matter from animal waste can be a pile of chicken, goat, cow, buffalo, either used directly or composted first. Manure can be derived from his own farm, from agricultural land around the site or brought in from other locations. Manure is a source of some nutrients such as nitrogen, phosphorus, potassium, and others. However, nitrogen is one of the main nutrient for most plants that can be obtained from the pile. Potassium deficiency in some particular location can not be corrected with a dose of common pile. Needs some plants may be obtained by application pile> 25 t ha. Nitrogen from the pile is generally converted into nitrate form is available. Nitrate is soluble and moves into the root zone of plants. This form together with a form that can be taken up by plants of inorganic fertilizer sources of plant. Manure contains nutrients concentrations varied depending on the type of livestock, food, life, and health of livestock. Usually farmers seeking land besides also seeking animals, so pile is a component of agricultural fertilizer. Available but insufficient pile needs, so its use is sometimes not give significant improvement and continuous outcomes. The use of pile as a plant fertilizer nutrient cycle which is very useful in optimizing the use of renewable natural resources, on the other hand the use of pile can reduce the nutrients that are toxic to plants. Various research indicates that most land-intensive agriculture has experienced declining productivity and land degradation, primarily associated with a very low content of organic carbon in the soil, which is 2%. Though required to obtain optimum productivity of organic carbon of about 2.5%. Organic fertilizers are very useful for the improvement of agricultural production both in quality and quantity, reduce environmental pollution, and improve the quality of the land in a sustainable manner. The use of organic fertilizer in the long term can increase the productivity of land and prevent land degradation. Source material for organic fertilizer is very diverse, with the physical characteristics and chemical constituents are so diverse that the effect of the use of organic fertilizer to the soil and plants can vary. In addition, the role big enough to repair physical, chemical and biological soil environment. Organic fertilizer added to the soil will undergo several phases of renovation by soil microorganisms to become humus. Organic materials also serve as a source of energy and food soil microbes that can improve the microbial activity in the supply of plant nutrients. The addition of organic matter in addition to as a source of nutrients for plants, as well as a source of energy and nutrients for microbes. The basic ingredients of organic fertilizers derived from crop residues contain less hazardous materials. The use of manure, industrial waste and municipal waste as compost ingredients because many contain harmful heavy metals and organic acids that can pollute the environment. During the composting process, some of these hazardous materials will be concentrated in the final product fertilizer. It is necessary for the selection of materials containing basic compost hazardous materials and toxic (B3). Organic fertilizer granules can act as the primary binder into the soil in the formation of secondary granule fertilizer. This situation affects the storage, water supply, soil aeration, and soil temperature. Organic matter to carbon and nitrogen are many, such as straw or husks greater influence on the improvement of soil physical properties compared with decomposed organic matter such as compost. Organic fertilizers have important chemical functions such as the provision of macro nutrients (nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur) and micronutrients such as zinc, copper, cobalt, barium, manganese, and iron, although relatively few in number. [8] The Elements The macro and micro nutrients needed for plant growth, especially for lovers of ornamental plants. Many actors and lovers of ornamental plants like to ask about the composition and content of fertilizer and percentage content of nitrogen, phosphorus and potassium are appropriate to plant seedlings, juvenile, or adult / adult. Function macro nutrients: Nitrogen (N): • Stimulate the growth of the plant as a whole • Is part of the cell (organ) plant itself • Works for the synthesis of amino acids and proteins in plants • Stimulate the growth of vegetative (green leaves, leaf length, leaf width) and vegetative stem growth (height and trunk size). • Plants that nitrogen deficiency symptoms: slow growth / stunted, leaves yellowish green, narrow leaves, short and tall, old leaves quickly turn yellow and die. Phosphorus (P): • Serves to transport energy metabolism in plants • Stimulates flowering and fruiting • Stimulates root growth • Stimulate the formation of seeds • Stimulate plant cell division and cell tissue enlarge • Plant the phosphorus deficiency symptoms are: formation of fruit / seeds and diminished, stunted, leaves turn purplish or reddish Potassium (K): • Functioning in the process of photosynthesis, transportation of assimilation, enzymes, and minerals ncluding water. • Increasing resistance / immunity of plants against diseases • Plants that potassium deficiency symptoms: stems and leaves become limp / her back, dark bluish green leaves and fresh greens are not healthy, the leaves turn yellow and dry ends, raised brown spots on the leaf. Organic fertilizers also works to increase the cation exchange capacity of the soil and form complexes with metal ions are toxic to plants such as aluminum, iron, and manganese
