Plants need sunlight, carbon dioxide, water and food (nutrients) for growth. There are a variety of nutrients in plant tissue but only 16 nutrients essential for the growth and yield. Nutrients can be divided into macro and micro nutrients.
Macro nutrients consisting of carbon, hydrogen, oxygen, nitrogen, fosforas, potassium, calcium, and sulfur maknesium. Micro nutrients are made up of iron, zinc, manganese, kuperam, boron, molybdenum and chlorine.Lack of nutrients carbon, oxygen, hydrogen does not occur at the plant is easy to tap the nutrients available to the plants from the air and water. Macro nutrients that the crop is probably less nitrigen, fosforas, potassium, calcium, and sulfur maknesium.
Macro nutrient deficiencies affect the part of the plant and the signs of his lack of simple and clearly visible on the leaves. Macro nutrient deficiencies often result in changes in form and color in plant leaves. In the early stages are often all or some of the surface of the leaves will change color from green to yellow (klorosis) and then dry up and die (necrosis if the situation worse.
Packet is intended to guide the lack of recognizing the signs of the dicot and monocot plants. The signs will look the same event at the lack of other crops.
Signs of malnutrition Macro In dicot crops (Rubber)
NitrogenLack of nitrogen nutrients to plant growth and reduce the size of the rubber canopy. The signs of a lack of first place in the old leaves, particularly in the leaves exposed to sunlight. Leaf color changes from pale green to yellow. In severe deficiency symptoms also occur in young leaves.
Fosforas Fosforas shortage will cause the bottom of the rubber leaves change color from green to yellow, bronze, is divided from the leaf tip and then spread throughout the leaf. This color change occurs in the leaves of young and middle aged and clearly in the leaves exposed to sunlight. Fosforas shortage will result in loss of rubber leaves.
Potassium In the spring rubber, potassium deficiency symptoms usually occur on older leaves exposed to sunlight. In severe conditions, the signs of deficiency also occurs in middle aged leaves. The leaves will show signs klorosis is divided end of the leaf and the leaf edges and signs of necrosis will be formed.
CalciumLack of calcium will affect the young leaves and shoots the rubber. End and the side leaves will show signs of burns white to light brown. The situation will cause severe impairment died during the shoot.
MagnesiumIn the rubber leaves the area between the leaf veins start from the sides of the leaves become yellowish when magnesium deficiency. These signs occur in older leaves and the leaves start yasng exposed to sunlight. Signs of magnesium deficiency is also known as the "Herring-bone pattern.
SulfurSulfur deficiency signs in the leaves is similar to the signs of Nitrogen. The difference is the lack of sulfur usually in young leaves. In the spring rubber, and necrosis klorisis sign is divided from the leaf tip and then spread happiness side of the middle leaves. Throughout the next leaves will turn yellow to brown and finally dry.
Signs of malnutrition Macro In monocots Crops (Corn / Rice)
NitrogenThe lack of nitrogen in the corn crop will result in growth retardation and yellowish (klorosis). This was followed by signs of necrosis, starting from the leaf tip. These signs will spread happiness all the bones and leaves the leaf. The leaves will change color to colkat and dry ends.
FosforasGrowth will be stunted the corn crop shortage Forforas. The sides or the entire surface of older leaves will change color to purple.
PotassiumSigns of potassium deficiency in maize occurs in older leaves. Yellow signs (Klorosis) first occurs at the end of the leaf and the leaf edges and then spread to the middle of the leaf. In severe conditions, the signs of necrosis will occur is divided tip and leaf edge.
CalciumLack of calcium in the plant to prevent the production of shoots and young leaves of gulungannya opening. In rice plants, young leaves will change color to yellow and the tip-end of the leaf will die.
MagnesiumMagnesium Deficiency in the corn crop will show signs of Klorosis between the leaf veins and leaf veins remain green. These signs occur in the leaves you and at the next level and end turn brown and dry.
SulfurSulfur Deficiency causes stunted growth and the stem are small and narrow Otis. The entire surface of the leaves change color and become light brown mark like a lack of Nitrogen. In contrast to nitrogen deficiency Sulfur deficiency signs starting on young leaves.
