Not all soils are created equal. Chemistry helps agriculture succeed in a variety of environments. This video explains how soils (often negatively charged) interact with nutrients (often positively charged) through cation exchange. The cation exchange capacity (CEC) of a soil determines how frequently and in what doses it should receive fertilizer. © 2016, NMSU Board of Regents.

E.12.3 Discuss the effects of soil pH on cation-exchange capacity and availability of nutrients. Note: the equation for the reaction of the Ca2+ ion and the PO43- ion isn't balanced correctly; there should be a 3 in front of the Ca2+ ion. Nitrogen is missing from this video, so I've included it here: Nitrogen is most available when the pH is nearly neutral. In highly acidic or alkaline soils, there is little breakdown of nitrogen. Plants become starved of nitrogen in these conditions, even with lots of added fertilizer.

This is a continuation of the soil talks in the last to videos. I will continue to dive deeper into this material as the months of winter go on. It is important to note that nurtured soils will always grow better grass than those that are neglected. Knowing your starting point and correcting what your soil is capable of first will allow for less NPK inputs over time.

Topic: pH value Why is pH value important to a farmer? What is happening to the tree? Is it merely because of pH? Yes, you are right. pH is the measure of acidity or basicity of a substance. It is expressed by positive numbers ranging from 0 to 14 where 7 indicates a neutral value, that is, neither acidic nor basic. When the pH value of a substance is below 7, it is termed as acidic and when it is above 7, it is termed as basic. The pH value of ideal soil is usually close to neutral. It ranges from about 6.5 to 7.5. If we don't maintain this pH, growth of most of the plants is adversely affected. Are you shocked? Did the white marble just turn yellowish brown due to acid rain? Yes, you are right. The pH of rainwater is about 5.6. This means that rainwater is slightly acidic. This slightly acidic nature of rainwater does not really cause any damage. But, in last few years, many harmful substances are being released into the atmosphere. Addition of these substances drops the pH of rainwater. In certain cities, the proportion of these harmful substances is so high in the atmosphere that it drops the pH of rainwater to a much lower level making it strongly acidic. When this strongly acidic rainwater falls down, it is termed as acid rain. This acid rain not only discolors white marbles, but also harms human beings and animals in several ways. Did the plant just turn yellow? Why do you think this happened? The plant turned yellow due to increase in pH value of the soil. A pigment named chlorophyll gives a plant its green color. The plant prepares chlorophyll with the help of iron. When the plant absorbs water from soil, it also takes in iron present in that soil and prepares chlorophyll. However, when the pH of soil increases, that is, when it becomes more basic, the availability of iron decreases. As a result, the plant does not get the required amount of iron to make chlorophyll and hence, it turns yellow. Also, besides the availability of iron, pH value of soil also affects the level of toxic substances, growth of bacteria and roots, etc. Thus, when a farmer has to grow any crop, he has to know the value of pH of his soil for a good yield. Otherwise, his crop will face undesirable consequences and ultimately, he may suffer a great loss.

In this episode, Octavia takes a look at Cation Exchange Capacity. Soil is made up of a combination of organic matter and mineral particles. The mineral particles are split into three distinct groups based on size: sand, silt and clay. Every soil has a different composition; some have more clay, some more sand. But it’s the unique blend of these components that determines the properties of soil – this is termed soil texture. In this video, we talk about the unique properties of clay; the fact that it has a huge surface area and that fact that the particles are usually negatively charged, and how this has relevance to plant biology. At 59 Degrees we are paving the way forward for a healthier soil community. We believe that in order to promote healthy, happy plants, we need healthy, happy microorganisms. We grow communities of these unique soil microorganisms that you can use directly in your soil and on your plants – from salad crops to mighty oaks. By adding this beneficial life to your soil you will transform the health of your plants. For more information visit www.59degrees.se

This comment about the video lecture explains about ion exchange chromatography principle. It also explains the step-by-step process of ion exchange chromatography. That includes the the cation exchange chromatography and anion exchange chromatography. Ion exchange chromatography involves using positive and negative in charge ions to separate charged molecules from a mixture. In the positive this is a problem was in video.

This video lecture talks about Ion exchange chromatography in Hindi, Ion Exchange chromatography, cation exchange chromatography, anion exchange chromatography, ion exchange chromatography practicle, lab procedure, PI of Protein, Zwitter ion, Ph of buffer solution in ion exchange chromatography. Ion exchange chromatogram This lecture explains about the instrumentation, principle of Ion exchange Chromatography. Ion chromatography is a chromatography process that separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids. However, ion chromatography must be done in conditions that are one unit away from the isoelectric point of a protein.The two types of ion chromatography are anion-exchange and cation-exchange. Cation-exchange chromatography is used when the molecule of interest is positively charged. The molecule is positively charged because the pH for chromatography is less than the pI. In this type of chromatography, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. Anion-exchange chromatography is when the stationary phase is positively charged and negatively charged molecules (meaning that pH for chromatography is greater than the pI) are loaded to be attracted to it.It is often used in protein purification, water analysis, and quality control. The water-soluble and charged molecules such as proteins, amino acids, and peptides bind to moieties which are oppositely charged by forming ionic bonds to the insoluble stationary phase.The equilibrated stationary phase consists of an ionizable functional group where the targeted molecules of a mixture to be separated and quantified can bind while passing through the column—a cationic stationary phase is used to separate anions and an anionic stationary phase is used to separate cations. Cation exchange chromatography is used when the desired molecules to separate are cations and anion exchange chromatography is used to separate anions.
