Nitrogen (N) — Did you know that about 80 percent of the air you breathe is nitrogen? It's true. In fact, every acre of land in the world is covered by about 75 million pounds of N...37 thousand tons. Not a pound of that N can be used by crop plants until it is changed by natural processes or by commercial fertilizer production. Through various processes of 'fixation,' gaseous atmospheric N is changed to a plant-usable form... either ammonium or nitrate. It can be fixed by lightning and carried to the Earth's surface in rain or snow. It can be fixed by certain organisms in the soil and nodules on legume roots. Industrial fixation supplies the millions of tons of commercially produced N fertilizers required to grow crops around the world. Nitrogen is required in greater quantities by crops than any of the other essential nutrients, except potassium. Some crops take up more K than N.  Learn More

 

Phosphorus (P) — There is no way around it: phosphorus is essential for plant growth. The element P is present in every living cell, both plant and animal. No other nutrient can be substituted for it. Phosphorus is one of the 16 essential nutrients that plants need for growth and reproduction. Phosphorus is considered one of the three major nutrients. They are termed major nutrients because of the relatively large amounts utilized by plants and the frequency with which their deficiencies limit plant growth.  Learn More

 

Potassium (K) — Potassium is a mineral nutrient essential to both plants and animals. For example, it is the third most abundant mineral in our bodies, surpassed only by calcium and phosphorus. More than 85 percent of K in the human body is found in major organs such as muscles, skin, blood and the digestive tract. Neither animals nor plants can survive without adequate supplies of K...its effects are real. Plants require more K than any other nutrient except nitrogen. Agronomic crops contain about the same amounts of N and K, but K content of many high-yielding crops is even higher than that of N. Unlike other nutrients, K does not form compounds in plants, but remains free to 'regulate' many essential processes...including enzyme activation, photosynthesis, water use efficiency, starch formation and protein synthesis.   Learn More

 

Calcium (Ca) — Don't let your calcium guard down. This low-key essential nutrient carries a heavy load in plant growth. Too often, however, it takes a back seat as soil fertility programs are developed for many high yield and high quality crops. There are some exceptions. Peanut and tomato growers, for example, emphasize good Ca nutrition. Do they know something about Ca that others do not? The answer comes with a better understanding of Ca contributions to soil fertility and to crops under intensive management or stress.   Learn More

 

Magnesium (Mg) — It's a rule that for proper germination, a bushel of wheat seed needs the amount of oxygen contained in 900 cubic feet of air. Oxygen is required to release chemical energy in seeds. During germination, that bushel of seeds produces the same amount of energy needed by a tractor to plow an acre of land. Magnesium is required for crops to capture the sun's energy for growth and production. Magnesium is classified as a secondary nutrient, but it has a major effect on crop and animal production.   Learn More

 

Sulfur (S) — Everyone knows that a chain is only as good as its weakest link. The weak link in many fertility programs is often overlooked- sulfur. Why has sulfur become the weak link? Today, Sulfur is becoming more of a limiting nutrient in crop production than in the past. The reasons for this increasing need include: higher crop yields which require more sulfur; increased use of high analysis fertilizers containing little or no sulfur; reduced amounts of atmospheric sulfur fallout in rainfall; and reduced soil sulfur reserves from organic matter losses due to mineralization and erosion.

Boron (B) — It's a fact that boron is required by crops for their growth and reproduction. Boron deficiencies are widespread across North America. Responses to B fertilization have been documented in 43 states in the U.S. and throughout Canada. Alfalfa frequently responds to B, but responses also occur in a large number of fruit, vegetable, and field crops. Learn More

 

Copper (Cu) — Copper is a micronutrient. That means plants contain less Cu than other nutrients, like nitrogen. In fact, plants contain 2,500 times less Cu than N, yet Cu is as necessary for the plant growth as is N. Plants need Cu to complete their life cycle- it's for certain.  Learn More

 

Iron (Fe) — Iron is essential for crop growth and food production, even through only small amounts are required compared to some of the other nutrients such as nitrogen, phosphorus, and potassium. For example, a 150 bushel corn crop removes only about 0.10 pounds of Fe from the soil; 1,000 pounds of lint cotton removes about 0.07 pounds. However, these small amounts of Fe must be available to the crop if it is to grow normally and produce the corn and cotton or other crops. Without Fe, the benefits of all other good management practices would be of little or no value.  Learn More

 

Manganese (Mn) — Manganese is one of the 16 essential elements and is mandatory for plant growth and reproduction. Manganese is considered a micronutrient because plants require only small amounts. This designation, however, is unrelated to its relative abundance in soils or its importance as a plant nutrient. Relatively large quantities of Mn can occur in soils, but only a small fraction is normally available at any one time.  Learn More

 

Molybdenum (Mo) — An essential plant nutrient. Only a few ounces of Mo per acre can correct yield-limiting deficiencies. Molybdenum is needed by the plant in the synthesis and activation of nitrate reductase, an enzyme which reduces nitrate to ammonium in the plant.  Learn More

 

Zinc (Zn) — It's not just a good idea that the speed of light is 186,000 miles per second- It's the law. Without this law of physics it would be impossible to precision level a farm field with a laser, for example. Crop plants require zinc. Zinc is one of the 16 essential nutrients that plants need for growth and reproduction. Zinc is a micronutrient and is required in smaller amounts than some other nutrients, but it is essential. If Zn is limiting or in short supply, crop yields and farm profits will suffer, and crop utilization of other fertilizer nutrients, such as nitrogen, will decrease. Poor nutrient utilization from an imbalanced fertility program is an environmental concern...and cuts profits.  Learn More

 

Chloride (Cl) — Until recently, chloride was thought to be unimportant as a plant nutrient. We now know Cl increases crop yields by correcting deficiencies and by suppressing many disease organisms.   Learn More

 

Cobalt (Co) — Although cobalt has not been proven essential for higher plant growth, modulating bacteria need it for fixing atmospheric N in legumes.   Learn More

 

Vanadium (V)  — Although it is relatively obscure, vanadium has been shown to have a role in plant nutrition. Foliar application to cotton has increased lint cotton yields, both dry land and irrigated, by 50 pounds per acre without increasing the crop's water requirements. Vanadium also increased cotton grade.  Learn More
