Why do plants produce far more sugar than they need?
to which @canadianer responded , "Yes, plants require oxygen to generate ATP from sugar. However, they generate far more sugar (and O2) than they use." Why do plants produce all that extra sugar, especially given that sugar is thermodynamically expensive? One reason, I believe, is to produce fruit and so recruit animals to help with reproduction.

Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.
Why do plants need nitrogen phosphorus and potassium?
Nitrogen is used by plants for lots of leaf growth and good green color. Phosphorous is used by plants to help form new roots, make seeds, fruit and flowers. It's also used by plants to help fight disease. Potassium helps plants make strong stems and keep growing fast.
How do plants take nutrients?
Plants take nutrients by 2 ways: passive and active. It is very important to differentiate between passive and active nutrients, so you can correctly fix nutrient deficiencies.
What is the key factor in plant growth?
Plant nutrition is a key factor in growth and yield. But how can we know which nutrient is missing? Or which is the best fertilizer for our crop?
What are passive nutrients?
Passive nutrients are chemicals moving in plants by mass flow and ion diffusion. The nutrients moving by mass flow will be directly related to plant transpiration. If plants have a proper transpiration, then there will be no issue with the movement of these nutrients, but if transpiration is affected, then even having the nutrient present in your fertilizer will not help plants be able to move passive nutrients efficiently and nutrient deficiency symptoms can appear. Some passive nutrients are: Calcium (strongly related to mass flow), Magnesium (strongly related to mass flow), Sulfur, Iron, Copper and Boron. On the contrary, active nutrients can always be taken up by the plant when available in our fertilizer.
When do plants need nutrients?
Plants do not need nutrients during all the seasons of the plant's growth. They need nutrients only when they are in growing phase. Most of the flowering plants and vegetables grow in the spring season. In India, the spring season refers to February to March. Apply manures before the onset of the spring.
What are the nutrients that plants need to grow?

Do people know how to grow plants?
Most of the people know how to grow plants. But they are not sure about the problems that plants face while growing. So keep on reading to get more information about essential nutrients and plant's unusual behavior regarding their growth and some of the visual symptoms that plants show.
Why is plant nutrition important?
Implementing proper plant nutrition is a critical step to crop management that enables growers to address common problems while achieving – and often exceeding – production goals.
What nutrients do plants need to grow?
Plants receive limited nutrients when soil temps drop below favorable zones. Fertilizers with proper levels of nitrogen, phosphorus and potassium can supplement a seedling with the right nutrition, promoting growth and increased plant vigor.
Why is it important to include macronutrients in crop management?
Including a blend of macronutrients along with specially crafted compounds early in your crop management program can increase the plant’s uptake of nutrients and go a long way toward improving plant mass, seedling vigor and uniform emergence, even during stressful times.
Why is grain fill so poor?
Seeing poor grain fill and retention? You may have a pollination problem, extreme heat and/or a boron deficiency. Late in a plant’s life cycle, the highest nutrient demand comes right at grain fill. If nutrients aren’t available during this critical time, your yield may suffer. Boron is essential for proper plant development. During pollination, it opens up pollen tubes and moves sugars to aid in fruit quality and development throughout the plant. Boron also protects against pod abortion, increasing flowering and grain retention.
Why are my plants' leaves yellowing?
Seeing slow plant growth, yellowing leaves or stunted plants early in your plants’ life cycle? You may have a nitrogen-loss problem, otherwise known as leaching. Nitrogen is essential to plant growth, and your soil composition could be contributing to nitrogen loss. Nitrogen management aids can help protect your nitrogen, make nitrogen available to plants for longer and reduce leaching. When inputs are kept in the root zone, plants are likely to grow faster. For best results, choose an aid formulated for your crop and preferred application method to ensure you get the most out of your nitrogen.
Why is nitrogen loss important?
You may have a nitrogen-loss problem, otherwise known as leaching. Nitrogen is essential to plant growth, and your soil composition could be contributing to nitrogen loss. Nitrogen management aids can help protect your nitrogen, make nitrogen available to plants for longer and reduce leaching.
What does boron do to a plant?
During pollination, it opens up pollen tubes and moves sugars to aid in fruit quality and development throughout the plant. Boron also protects against pod abortion, increasing flowering and grain retention. Plant Nutrition Products. POOR ROOT DEVELOPMENT.
Why add organic matter to plants?
Fresh organic matter added at the bases of plants – or in between rows – gives a little extra nutrition in the form of green manure. It also helps with keeping weeds down, maintaining moisture, and forestalling erosion and runoff.
What do gardeners learn?
.Experienced gardeners – and farmers, too – learn the exact nutrients needed at any stage of growth, for health, beauty, and even tastiness. Further, they can pick up on what plants need through various signs and indicators, diagnosing illnesses, pest issues, and nutrient deficiencies.

Make sure to take note of the important insights and tips ahead before selecting what plant nutrients you need.
Does composting increase microbial activity?
Further, the addition of composted organic matter revs up microbial activity in the soil, increasing nutrient output in large amounts, though much more slowly than fertilizers.
What are the nutrients that plants need?
Plant cells need essential substances, collectively called nutrients, to sustain life. Plant nutrients may be composed of either organic or inorganic compounds. An organic compound is a chemical compound that contains carbon, such as carbon dioxide obtained from the atmosphere. Carbon that was obtained from atmospheric CO 2 composes the majority of the dry mass within most plants. An inorganic compound does not contain carbon and is not part of, or produced by, a living organism. Inorganic substances, which form the majority of the soil solution, are commonly called minerals: those required by plants include nitrogen (N) and potassium (K) for structure and regulation.
How do plants absorb nutrients?
Plants can absorb inorganic nutrients and water through their root system, and carbon dioxide from the environment. The combination of organic compounds, along with water, carbon dioxide, and sunlight, produce the energy that allows plants to grow. Inorganic compounds form the majority of the soil solution. Plants access water though the soil. Water is absorbed by the plant root, transports nutrients throughout the plant, and maintains the structure of the plant. Essential elements are indispensable elements for plant growth. They are divided into macronutrients and micronutrients. The macronutrients plants require are carbon, nitrogen, hydrogen, oxygen, phosphorus, potassium, calcium, magnesium, and sulfur. Important micronutrients include iron, manganese, boron, molybdenum, copper, zinc, chlorine, nickel, cobalt, silicon and sodium.
Why is nitrogen important for plants?
Nitrogen is an important macronutrient because it is part of nucleic acids and proteins. Atmospheric nitrogen, which is the diatomic molecule N 2, or dinitrogen, is the largest pool of nitrogen in terrestrial ecosystems. However, plants cannot take advantage of this nitrogen because they do not have the necessary enzymes to convert it into biologically useful forms. However, nitrogen can be “fixed,” which means that it can be converted to ammonia (NH 3) through biological, physical, or chemical processes. As you have learned, biological nitrogen fixation (BNF) is the conversion of atmospheric nitrogen (N 2) into ammonia (NH 3 ), exclusively carried out by prokaryotes such as soil bacteria or cyanobacteria. Biological processes contribute 65 percent of the nitrogen used in agriculture. The following equation represents the process:
What are the two essential elements?
The essential elements can be divided into two groups: macronutrients and micronutrients. Nutrients that plants require in larger amounts are called macronutrients. About half of the essential elements are considered macronutrients: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. The first of these macronutrients, carbon (C), is required to form carbohydrates, proteins, nucleic acids, and many other compounds; it is therefore present in all macromolecules. On average, the dry weight (excluding water) of a cell is 50 percent carbon. As shown in Figure 2, carbon is a key part of plant biomolecules.
Why do plants need microbial partners?
Plants may also enlist the help of microbial partners in nutrient acquisition. Particular species of bacteria and fungi have evolved along with certain plants to create a mutualistic symbiotic relationship with roots. This improves the nutrition of both the plant and the microbe. The formation of nodules in legume plants and mycorrhization can be considered among the nutritional adaptations of plants. However, these are not the only type of adaptations that we may find; many plants have other adaptations that allow them to thrive under specific conditions.
How do fungi help plants?
Mycorrhizae help increase the surface area of the plant root system because hyphae, which are narrow, can spread beyond the nutrient depletion zone. Hyphae can grow into small soil pores that allow access to phosphorus that would otherwise be unavailable to the plant. The beneficial effect on the plant is best observed in poor soils. The benefit to fungi is that they can obtain up to 20 percent of the total carbon accessed by plants. Mycorrhizae functions as a physical barrier to pathogens. It also provides an induction of generalized host defense mechanisms, and sometimes involves production of antibiotic compounds by the fungi.
Why do plants need fungi?
These conditions are very common; therefore, most plants rely on fungi to facilitate the uptake of minerals from the soil. Fungi form symbiotic associations called mycorrhizae with plant roots, in which the fungi actually are integrated into the physical structure of the root. The fungi colonize the living root tissue during active plant growth.
Why do plants need potassium?
Plants use potassium to regulate the stoma’s opening and closing on the leaves’ undersides. This reduces water loss, increases drought tolerance , and is essential for the fruiting and flowering of all plants. It’s mainly present in soil and is derived from clay particles. Soils that have a low clay content, such as sand, may be low in this nutrient.
Why is nitrogen important for plants?
In other words, it encourages green vegetative growth, so it’s good for foliage. Nitrogen deficiency leads to stunted plant growth and leaf yellowing (chlorosis).
How does poor soil affect plant growth?
Poor soil structure can affect plant growth in many ways. When the soil is too compact it contains very little oxygen, which can cause the plant to suffocate. Furthermore, rain water will sit on its surface and not penetrate into the ground. Not only does this cause puddling and eventual rotting of plants above the soil, it can cause drought underneath and dehydration to the plant root system.
What is organic matter?
Organic matter is something that was once alive but is now dead— such as compost (made from plants, vegetables, and grass cuttings), leaf mold, well-rotted farmyard manure, and fauna.
Why do my plants turn purple?
Phosphorus deficiency shows through the plant’s leaves and stems, which become very dark green with purple veins. Prolonged deficiency can also cause stunted plant growth.
Why is phosphorus needed in soil?
This is required in smaller quantities than nitrogen, and needed for the conversion of light energy to chemical energy (ATP) during photosynthesis. It’s also used for cell signalling and the formation of flowers and seeds. Phosphorus quantities are usually adequate in most soils apart from those with no or little organic matter.
What happens if you don't eat the right foods?
With a continued lack of the right foods, we will become susceptible to all manner of health issues. Viruses, diseases, and brittle bones are just a few issues we may suffer, affecting long-term health and quality of life. Read on to learn how to spare your plants a similar fate by ensuring they have the balanced nutrition they need.
How does pH affect nutrient management?
Because plants can only take up nutrients that are dissolved in the growing medium, and pH affects nutrient solubility (Figure 2) , then the media pH affects nutrient management. For example, iron solubility (and uptake) generally decreases with increasing pH because iron precipitates out of the soil solution at higher pH levels. Phosphorus also precipitates out of solution at higher pH levels. Phosphorus uptake will be further reduced above pH 7.2 because any phosphorus left in solution is converted into a less available form. Nitrogen uptake can be indirectly affected by media pH because low pH decreases nitrification (conversion of ammoniacal nitrogen to nitrate nitrogen) or the conversion of urea to ammoniacal nitrogen.
How much water is in a plant?
Most plants are about 90 percent water and 10 percent dry matter.
