Plant Uptake of Mineral Nutrients from the Soil​

How do plants overcome these tradeoffs in order to absorb nutrients from soil water into their root hairs? This process relies upon proton pumps, cation channels, and anion cotransporter channels present in the membranes of the root hairs as follows:

  • The epidermal tissue of root hairs is lined by proton pumps (H+ ATPases), which use ATP as an energy source to pump protons out of the cells and into the soils, against their electrochemical gradient. These proton pumps create a strong electrochemical gradient with a high concentration of protons and a strong positive charge outside of the cell, and a low concentration of protons and relatively negative charge inside of the cell. These protons pumped into the soil by the proton pumps cause two direct outcomes:
    • The positively-charged protons bind to the negatively-charged clay particles in the soil, releasing the cations from the clay in a process called cation exchange. The cations then diffuse down their electrochemical gradient into the root hairs through cation channels. (The soil environment is highly positively charged, so it is energetically favorable for cations to move into the root hairs and out of the soil environment).
    • The high concentration of protons in the soil creates a strong electrochemical gradient that favors transport of protons back into the root hairs. Plants use co-transport of protons down their concentration gradient as the energy source to also move anions against their concentration gradient into the root hairs. This process occurs through anion cotransporter channels. (The soil environment is highly positively charged, so it is energetically unfavorable for anions to leave the soil, but highly energetically favorable for protons to leave the soil).

🤷‍♂️ not that this is in anyway new news

Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters (lakes, rivers and coastal waters), in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth.[1]

FORMS OF FE IN THE NATURAL ENVIRONMENT​

The most abundant form of Fe in soils is ferric oxide (Fe2O3) or hematite, which is extremely insoluble and imparts a red color to the soil. The oxide form is commonly hydrated. In aerobic soils, the oxide, hydroxide, and phosphate forms control the concentration of Fe in solution and its availability to plants. In typical aerated plant production systems of acceptable reaction (pH) of +/- 6.0, the concentrations of ferric (Fe+++) and ferrous Fe++ iron are on the order of 10-15 molar (very low concentration). As pH increases by one unit, activity of Fe+++ decreases by 1000-fold due to the formation of insoluble Fe +++hydroxide. Under reducing conditions—addition of H+ or other reductants—Fe solubility increases. Under such situations, Fe can be adsorbed on soil as an exchangeable ion.

In certain soil situations, carbonate or sulfide compounds may form with Fe. Commonly in waterlogged situations, ferric iron is reduced to the ferrous state. If sulfates also are abundant in the soil, these become oxygen sources for bacteria and black-colored ferrous sulfide is formed

Where organic matter is present in soils, Fe may be present in its reduced state as Fe++ in the soil solution or adsorbed onto soil particle surfaces. Organic matter in soils plays a major role in the availability of Fe to plants. Biochemical compounds or organic acids (aliphatic acids or amino acids) and complex polymers (humic and fulvic acids) can form soluble complexes with Fe, or act as chelating agents and thereby increase Fe availability to plants (chelating agents are organic compounds that complex with Fe and help hold Fe in more soluble forms).


Ferromagnetism is an unusual property that occurs in only a few substances. The common ones are the transition metals iron, nickel, and cobalt, as well as their alloys and alloys of rare-earth metals. It is a property not just of the chemical make-up of a material, but of its crystalline structure and microstructure.

Electromagnetic interactions are responsible for the glowing filaments in this plasma globe.

It also underlies many properties of organic compounds and molecular solids, including their solubility in polar and non-polar media.

  • Nanomaterials in agriculture:
    Researchers are exploring the use of nanomaterials in agriculture, such as nanostructured fertilizers or pesticides, where understanding crystal structures of nanoparticles could be important for designing their properties and delivery mechanisms.
  • Biomineralization:
    Certain biological processes in plants and animals involve the formation of mineral crystals, like calcium carbonate in seashells or silica in plant cell walls. Understanding the crystal structures of these minerals could be relevant in studying their formation and potential applications in agriculture.
  • Soil structure and porosity:
    The arrangement of soil particles can be considered analogous to a crystal structure, and the porosity or spaces between particles can affect water infiltration and root development, which are key factors in agriculture.
By definition, type of structure describes the form or shape of individual aggregates. Generally, soil technicians recognize seven types of soil structure, but here only four types are used. They are rated from 1 to 4 as follows:

1 Granular and crumb structures are individual particles of sand, silt and clay grouped together in small, nearly spherical grains. Water circulates very easily through such soils. They are commonly found in the A-horizon of the soil profile;
GR000139.JPG
2 Blocky and subangular blocky structures are soil particles that cling together in nearly square or angular blocks having more or less sharp edges. Relatively large blocks indicate that the soil resists penetration and movement of water. They are commonly found in the B-horizon where clay has accumulated;
GR000136.JPG
3 Prismatic and columnar structures are soil particles which have formed into vertical columns or pillars separated by miniature, but definite, vertical cracks. Water circulates with greater difficulty and drainage is poor. They are commonly found in the B-horizon where clay has accumulated;
GR000137.JPG
4 Platy structure is made up of soil particles aggregated in thin plates or sheets piled horizontally on one another. Plates often overlap, greatly impairing water circulation. It is commonly found in forest soils, in part of the A- horizon, and in claypan* soils.

  • Montmorillonite (smectite) – (Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·nH2O (clay sheets verm)
  • The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.
  • Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500 million years by various forms of life, such as coral and shellfish.
  • Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers.[1] The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases.

Plant roots can be used as anodes and cathodes in microbial fuel cells (MFCs) to generate electricity:

1729048954814.png

  • Anode
    The anode is placed in the soil, where the roots of the plant release organic compounds that are oxidized by bacteria. This process releases electrons that are transferred to an electrode to generate an electric current.

    1729049116255.png
  • Cathode
    The cathode is exposed to oxygen in the air-water interface above the soil. The cathode is the electrode where electricity is given out or flows out.
Plant-microbial fuel cells (P-MFCs) are a sustainable and renewable way to produce electricity. They can be used in gardens, on green roofs, and indoors. P-MFCs are an attractive option for remote applications or locations with limited electrical infrastructure.


Here are some other things to know about plant roots and anodes and cathodes:


  • Root electrotropic response
    Roots can respond to electric fields and grow towards the cathode or anode. The typical response of uninjured roots is growth towards the cathode.


  • Cathode working patterns
    The relative locations of the plant roots and the cathode can affect the cathode's working pattern. Laying plant roots directly on the air-cathode can improve the cathode's working pattern.


  • Anaerobic and aerobic metabolism
    The type of metabolism of the microorganisms in the MFC affects the voltage generation. Anaerobic metabolism occurs in the absence of oxygen, while aerobic metabolism involves oxygen.

Origin of biofilms​

Biofilms are thought to have arisen during primitive Earth as a defense mechanism for prokaryotes, as the conditions at that time were too harsh for their survival. They can be found very early in Earth's fossil records (about 3.25 billion years ago) as both Archaea and Bacteria, and commonly protect prokaryotic cells by providing them with homeostasis, encouraging the development of complex interactions between the cells in the biofilm.[3]

Taxonomic diversity​

Many different bacteria form biofilms, including gram-positive (e.g. Bacillus spp, Listeria monocytogenes, Staphylococcus spp, and lactic acid bacteria, including Lactobacillus plantarum and Lactococcus lactis) and gram-negative species (e.g. Escherichia coli, or Pseudomonas aeruginosa).[88] Cyanobacteria also form biofilms in aquatic environments.[89]

Biofilms are formed by bacteria that colonize plants, e.g. Pseudomonas putida, Pseudomonas fluorescens, and related pseudomonads which are common plant-associated bacteria found on leaves, roots, and in the soil, and the majority of their natural isolates form biofilms.[90] Several nitrogen-fixing symbionts of legumes such as Rhizobium leguminosarum and Sinorhizobium meliloti form biofilms on legume roots and other inert surfaces.[90]

Along with bacteria, biofilms are also generated by archaea[51] and by a range of eukaryotic organisms, including fungi e.g. Cryptococcus laurentii[91] and microalgae. Among microalgae, one of the main progenitors of biofilms are diatoms, which colonise both fresh and marine environments worldwide.[92][93]

For other species in disease-associated biofilms and biofilms arising from eukaryotes, see below.

  • Amyloid – Insoluble protein aggregate with a fibrillar morphology

Electrochemically active biofilms​

Electrically active microorganisms create electrochemically active biofilms (EABs) which have been used in microbial fuel cells to generate an electric current.[22] These fuel cells have also been paired with wastewater treatment by taking advantage of the many biodegradable organic components in wastewater. It has been considered as an alternative to conventional wastewater treatment methods, or as a step before the membrane reactor, or to reduce the amount of solid sludge produced. Researchers have looked at treating dairy, animal carcass, brewery, winery, and domestic wastewater, to name a few, with microbial fuel cells. This technology, however, has yet to be fully successful on a large scale due to low power density and the fluctuating temperature and composition of real wastewater.[23] EABs have also been looked at to produce hydrogen, which is currently produced from mostly non-renewable fossil fuels. In the new technology of microbial electrolysis cells, EABs on the anode break down organic substrates to CO2, electrons, and protons. Furthermore, EABs have been used for the synthesis of metal nanoparticles and metal semiconductor composites as an alternative to traditional chemical methods.[22]

From the perspective of biochemistry, ATP is classified as a nucleoside triphosphate, which indicates that it consists of three components: a nitrogenous base (adenine), the sugar ribose, and the triphosphate.

Microorganisms have shown to use nanowires to facilitate the use of extracellular metals as terminal electron acceptors in an electron transport chain. The high reduction potential of the metals receiving electrons is capable of driving a considerable ATP production.[18][3]


Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4. It is one of the oxides of iron, and is ferrimagnetic;[6] it is attracted to a magnet and can be magnetized to become a permanent magnet itself.[7][8] With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.[7][9] Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism.[10]

Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak.[7] Small grains of magnetite are very common in igneous and metamorphic rocks.[11]

The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide.[12]

The most ancient example of biomineralization, dating back 2 billion years, is the deposition of magnetite,

Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP), and uridine triphosphate (UTP)—throughout the cell for the many cellular functions that demand energy, including: amino acid, protein and cell membrane synthesis, moving the cell and cell parts (both internally and intercellularly), cell division, etc..[2] In addition, nucleotides participate in cell signaling (cyclic guanosine monophosphate or cGMP and cyclic adenosine monophosphate or cAMP) and are incorporated into important cofactors of enzymatic reactions (e.g., coenzyme A, FAD, FMN, NAD, and NADP+).

Prebiotic synthesis of ribonucleosides​

In order to understand how life arose, knowledge is required of the chemical pathways that permit formation of the key building blocks of life under plausible prebiotic conditions. According to the RNA world hypothesis free-floating ribonucleosides and ribonucleotides were present in the primitive soup. Molecules as complex as RNA must have arisen from small molecules whose reactivity was governed by physico-chemical processes. RNA is composed of purine and pyrimidine nucleotides, both of which are necessary for reliable information transfer, and thus Darwinian natural selection and evolution. Nam et al.[5] demonstrated the direct condensation of nucleobases with ribose to give ribonucleosides in aqueous microdroplets, a key step leading to RNA formation. Also, a plausible prebiotic process for synthesizing pyrimidine and purine ribonucleosides and ribonucleotides using wet-dry cycles was presented by Becker et al.[6]

Jiffy has those little pucks everyone loves. Not surprising they have a good seedling starter mix.

Have a couple bags of Fox Farm Light Warrior seed starter waiting for next round of starts next spring.

We also have a local mulch and media mixing place which sells media to nurseries and retail. They can custom blend media and you can even buy in bulk totes! They may have a seedling germination media. I usually just use the regular unfertilized media and amend.

Need to give those little seeds the best chance. My homegrown big seeds germinate and become seedlings quick with less issues than the small ones which are common for purchase.

Temperature is hugely important during germination and early seedling development. Don't let them drop below 65-70F I think it was.
