Prof. LJIET Ahmedabad, India Abstract—This review paper based on micro nutrients effects and analysis of different methods applied and which type of results are come out. We take overview of nutrients effects on its value. Use data mining methods for getting given result. Keywords—Micro nutrients study, Data mining Methods I. INTRODUCTION In Agriculture sixteen fertilizer nutrients area unit essential for correct crop development that absorb from soil. Everyone is equally necessary to the plant that needed in immensely totally different amounts. These essential components variations have led to the grouping into 3 classes like primary (macro) nutrients, secondary nutrients and micronutrients that all are required to plant or crop for develop. Primary (macro) nutrients are nitrogen (N), phosphorus (P), and potassium (K). They’re the foremost of times needed during a crop fertilization program. All area unit would like within the greatest total amount by plants as fertilizer. The secondary nutrients area unit Ca (Ca), magnesium (Mg), and Sulphur (S). For most crops, these 3 are required in lesser amounts that the first nutrients. They’re growing in importance because of additional tight clean air standards and efforts to boost the atmosphere in crop fertilization programs. The micronutrients area unit boron (B), chlorine (Cl), cooper (Cu), iron(Fe), manganese (Mg), molybdenum (Mo), cobalt (Co), silicon (Si) and Zn (Zn). These fertilizer components area unit employed in terribly little amounts, however they're even as necessary to plant development and profitable crop production because the major nutrients [2] [3]. Especially, they work "behind the activators of the many plant functions. All nutrients area unit required however it's some restricted rating. In step with their restricted rate, each nutrient has its own totally different impact on crops. Macro or primary components area unit importance for the expansion of the plant however small components aren't slighter than those of major components. Because of deficiency of those are leaves, branches and fruits might not properly grow and that they might even are the fruits quality yet as production. Small components conjointly facilitate in development of enzymes, hormones, chlorophyll and within the absorption of major components Nutrient functions, deficiency symptoms, convenience are used for agricultural land that is extremely effectively offer impact on soil. II. NUTRIENT FUNCTION [4][5] Nutrient Deficiency and Excess Nutrient Deficiency Excess Nitrogen (N) Reduced growth, light- weight green to yellow foliage. Reds and purples, Sometimes with pink tints Succulent growth, Thick and brittle; leaves are dark green, Poor fruit set; excess ammonia will induce Ca deficiency Phosphorus (P) Reduced growth; leaves dark green; purple or red in older leaves Shows up as micronutrient deficiency of Fe, Zn, or Co Potassium (K) Reduced growth; Shortened internodes; Older leaves become burn; Poor flowering or fruiting Causes N deficiency in plant and should have an effect on the uptake of alternative positive ions like Mg and Ca Magnesium (Mg) Yellowish, bronze, chromatic color Little death spots in older leaves; Interferes with Ca uptake Calcium (Ca) Inhibition of bud growth; roots will flip black and rot; young leaves are rough structure is weak; Interferes with Mg absorption high Ca typically causes high pH that then precipitates several of the matter so that they become unavailable to the plant Sulfur (S) Rarely deficient; general yellowing of the young leaves Sulfur excess is usually in the form of air pollution Iron (Fe) Interveinal chlorosis, Soil high in Ca, Poorly drained soil, soil high in Mn, high pH, high P, soil high in heavy metals (Cu, Zn), Dryness of branches and leaves, Yellowing of leaves. Rare except on flooded soils Boron (B) Failure to set seed; Internal breakdown of fruit or vegetable; Death of apical buds, Giving rise to witches broom; Corkiness & Dryness of fruits, Internal rotting in plant Tips and edges of leaves exhibit necrotic spots coalescing into a marginal scorch Zinc (Zn) Young leaves are very small, Small size of leaves, Deformed leaves Poor germination; entire leaf is affected by chlorosis Copper (Cu) New growth small, Misshapen, wilted; Gummosis in plants, Dieback in plant, Discolor of leaf Can occur at low pH; shows up as Fe deficiency Manganese (Mn) Poor bloom size and color; induced by excessively high pH. Discoloration of leaves, Yellowing of leaves Reduction in growth, brown spotting on leaves; shows up as Fe deficiency; Molybdenum (Mo) Interveinal chlorosis on older or midstream leaves; Twisted leaves (whiptail); Yellow spots in the leaves, Loss of greenness in leaves Intense yellow or purple color in leaves; rarely observed Chlorine (Cl) Yellowing of leaves and fall from plants, Fading of plant Salt injury, leaf burn, may increase succulence Cobalt (Co) This need by plants recently established; essential for Nitrogen fixation Little is known about its deficiency or toxicity symptoms
