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

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
