Boron Deficiency

Boron deficiency       Boron (B) exists primarily in soil solutions as the BO33- anion — the form commonly taken up by plants. One of the most important micronutrients affecting membrane stability, B supports the structural and functional integrity of plant cell membranes. Interestingly, while higher plants require B, animals, fungi and microorganisms don’t. Micronutrients Read More

16 ESSENTIAL NUTRIENTS IN CROP DEVELOPMENT

Sixteen plant food nutrients are essential for proper crop development. Each is equally important to the plant, yet each is required in vastly different amounts. These differences have led to the grouping of these essential elements into three categories; primary (macro) nutrients, secondary nutrients, and micronutrients. PRIMARY (MACRO) NUTRIENTS Primary (macro) nutrients are nitrogen, phosphorus, Read More

Sulfur deficiency

Sulfur deficiency   Sulfur (S) is a part of every living cell and is a constituent of two of the 20 amino acids that form proteins. Unlike the other secondary nutrients like calcium and magnesium (which plants take up as cations), S is absorbed primarily as the S042- anion. It can also enter plant leaves Read More

Potassium deficiency

Potassium deficiency Potassium (K) is one of the essential nutrients and is taken up in significant amounts by crops. Potassium is vital to photosynthesis, protein synthesis and many other functions in plants. It’s classified as a macronutrient, as are nitrogen (N) and phosphorus (P). Plants take up K in its ionic form (K+). While potassium Read More

Phosphorus deficiency

Phosphorus deficiency One of three primary nutrients, phosphorus (P) is essential for plant growth. No other nutrient can be substituted for P — a plant must access it to complete its normal production cycle. Phosphorus is a vital component of adenosine triphosphate (ATP), the “energy unit” of plants. ATP forms during photosynthesis, has P in Read More

Oxygen

Oxygen Oxygen (O) is responsible for cellular respiration in plants. Plants acquire O by breaking down carbon dioxide (CO2) during photosynthesis and end up releasing the majority of it as an unnecessary byproduct, saving a small portion for future energy.   Post Views: 11

Nitrogen deficiency

Nitrogen deficiency Nitrogen (N) is essential for plant growth and is part of every living cell. It plays many roles in plants and is necessary for chlorophyll synthesis. Plants take up most of their N as the ammonium (NH4+) or nitrate (No3-) ion. Some direct absorption of urea can occur through the leaves, and small Read More

Molybdenum deficiency

Molybdenum deficiency Molybdenum (Mo) is a trace element found in the soil and is required for the synthesis and activity of the enzyme nitrate reductase. Molybdenum is vital for the process of symbiotic nitrogen (N) fixation by Rhizobia bacteria in legume root modules. Considering Mo’s importance in optimizing plant growth, it’s fortunate that Mo deficiencies Read More

Manganese deficiency

Manganese deficiency Manganese (Mn) functions primarily as part of enzyme systems in plants. It activates several important metabolic reactions and plays a direct role in photosynthesis. Manganese accelerates germination and maturity while increasing the availability of phosphorus (P) and calcium (Ca). Manganese (Mn) is taken up by plants as the divalent cation Mn2+. It functions primarily Read More

Magnesium deficiency

Magnesium deficiency   Hidden in the heart of each chlorophyll molecule is an atom of magnesium (Mg), making the nutrient actively involved in photosynthesis. Magnesium also aids in phosphate metabolism, plant respiration and the activation of many enzyme seasons. Plant growth requires energy, and lots of it. During germination alone, a bushel of wheat seed Read More

Iron deficiency

Iron deficiency Iron (Fe) is essential for crop growth and food production. Plants take up Fe as the ferrous (Fe2+) cation. Iron is a component of many enzymes associated with energy transfer, nitrogen reduction and fixation, and lignin formation. Iron (Fe) is involved in the production of chlorophyll, and Fe chlorosis is easily recognized on Read More

Copper deficiency

Copper deficiency   Copper (Cu) activates enzymes and catalyzes reactions in several plant-growth processes. Vitamin A production is closely linked to the presence of Cu as well, and it helps ensure successful protein synthesis. Classified as a micronutrient, only a small amount of this essential nutrient is needed for plant survival. Copper (Cu) is necessary Read More

Chlorine deficiency

Chlorine deficiency Plants take up chlorine (Cl) as the chloride (Cl–) anion. It’s active in energy reactions in the plant. Most Cl- in soils comes from salt trapped in parent materials, marine aerosols and volcanic emissions. Classified as a micronutrient, Cl- is required by all plants in small quantities. Research has shown that chloride (Cl-) Read More

Carbon

 Carbon Carbon (C) is responsible for all life on earth. Carbon dioxide (CO2) released into the atmosphere is recycled endlessly as part of the carbon cycle. Plants take CO2 from the air and use the C for energy, helping to build essential biological compounds such as carbohydrates and proteins.   Post Views: 14

Organic Fertilizers

Sooner or later, every gardener discovers that for good results — whether in the vegetable garden, perennial border, or lawn — replenishing soil nutrients is necessary. And one of the key choices is whether to use organic or synthetic fertilizers. Synthetic fertilizers are manufactured. Organic fertilizers are derived from plants and animals, and from naturally Read More

Nutrient Deficiencies in Plants

Nutrient Deficiencies in Plants Sometimes plants look unhealthy and we assume they have been attacked by pests. This could however be early signs of nutrient deficiency. If plants do not receive adequate proportion of essential minerals or they fail to thrive despite of proper growing conditions it signifies they are suffering from malnutrition. There are Read More
