Soil Food web – Predator-Prey Protists Bacteria Fungi Microarthropods are some of the main components in soil microbiology. Below is a predator/Prey food/eating chart. Arrows indicate who is eating what. Some of the food materials are organic (meaning they contain some carbon), while other organisms are eating inorganic materials (like NO3, NO and etc…) The tangled [...]
Aquatic Nitrogen Fixers for Fishless Aquaponics Systems. Nitrogen fixing is the way or a process where plants can take up nitrogen from the air and make it absorbable by roots. Plants cannot take nitrogen directly from the air. It first needs to be fixed. The chemical compound is NO3. Or called Nitrate. Nitrate is produced by [...]
In this episode we looking at two Nitrogen Cycles. This is a replacement for chemical pesticides and fungicides. Applications are done as compost teas. And applications are done with Azos bacteria. Nitrogen Cycle part1 from Paul Holowko on Vimeo. For More Information on Nitrogen Cycles, click here. Nitrogen Fixing Cycle Part 2 from Paul [...]
Azotobacteraceae’s purpose is to take food from the plant through the roots, eat it, change it to a protein. Once the protean is released, nitrifying bacteria covert it to a Nitrate. Nitrate is fixed nitrogen. It is the same thing as chemical fertilizer but made by the soil ecosystem. You can buy Azotobacter from any [...]
Rhizobium Bacteria is part of the nitrogen fixing cycle for Legumes. It has a symbiotic relationship with plants where starches are eaten by the bacteria and the bacteria give back proteins to the host plant. The protein is stored in nodules connected to the roots.

Fixed Nitrogen from Nematodes. This nitrogen cycle is mainly appart of late succession plants and forests. For Information on bacterial and mycorrhiza inoculants, click here. For More Information on Nitrogen Cycles, click here.
This is one of the more tricky and interesting Nitrogen Fixing Cycles. The Ammonium comes from the nitrogen eaten of bacteria by nematodes. By default, bacteria bodies have a C:N ratio of 5:1. Bacteria have a very narrow split between Nitrogen and Carbon. Nematodes have a C:N ratio of 100:1. The split between the Nitrogen [...]
Nitrogen Fixation by Cyanobacteria Cyanobacteria are important in the nitrogen cycle. Cyanobacteria are very important organisms for the health and growth of many plants. They are one of very few groups of organisms that can convert inert atmospheric nitrogen into an organic form, such as nitrate or ammonia. It is these “fixed” forms of nitrogen [...]
How is Fixed NO3 Made from Urea (NH2)2CO
Root hairs are thin-walled extensions of the epidermal cells in roots. They provide increased surface area and thus more efficient absorption of water and minerals. Water and dissolved mineral nutrients enter the plant via two routes. Water and selected solutes pass through only the cell membrane of the epidermis of the root hair and then [...]
This cycle exists for converting protists wastes and for synthetic fertilizer absorption by plant roots. Remember synthetic fertilizers are salts. They are made up of NO3NH4. These are two parts to this salt. The NO3 can be directly absorbed into the roots through osmosis. NH4 needs to go through a process of being changed into NO3 [...]
