What grows green grass and Healthy Crops in Western Soils?

Often our western soils have a problem with many of the 42 essential elements of plant nutrition being inhibited by the alkaline chemistry of the soil.  This simply means that the elements such as iron, zinc, copper, calcium, etc, etc, etc, are cemented into the matrix of the soil by way of a precipitation reaction called concretion.   This is where the term ‘Concrete’ comes from, where the mineral elements are not soluble with just water.  The process of getting these elements available for plant uptake requires a “solutioning” of the elements from the concreted soil, which is provided by the supramolecular chemistry of the organic matrix of humic molecules, and by the mycorrhizal fungi that are hopefully also present.    It’s one of the Mechanisms of Action for the Humic Molecules and the Mode of Action for the Mycorrhizal fungi. 

Another limiting factor is the availability of nitrogen in the form of amino acids, caused by a slow or weak Soil Food Web.   The SFW is the Terrestrial Biosphere of Micro-organisms and soil animals of all sizes, which all contain protein.    The largest most abundant part of this terrestrial biosphere should be coming from the cycling of mycorrhizal hyphae as they are constantly being replaced.   It’s been reported that the individual hyphae of mycorrhizal fungi only function for 5 to 7 days before they are replaced!  The cellular tissues of the hyphae have huge amounts of protein, which breaks down into amino acids, which accumulate in the soil and eventually get picked up by functioning hyphae of other mycorrhizal fungi and delivered to the plants as a major source of the nitrogen budget needed by the host plant.  Much of the protein organic substances of the cycling microorganisms also gets consumed by the grazers of the soil (other microbes) where the caloric value of the protein is used to multiply into more microbes.  
This is where we screw up in landscaping or farming, when we supplement our crops or urban landscapes with high analysis fertilizers rather than find a way to instigate a better functioning Soil Food Web.  Sure plants can use the 16% (plus or minus) analysis of nitrogen found in such products, but the best way for a plant to get nitrogen is by way of up-taking amino acids from the soil’s biosphere and not from acidified high salt index fertilizers.   The high analysis fertilizers don’t provide a protein caloric value to the soil microbes and most of the nitrogen never gets used by the plant as it’s too easily lost.  The result is a feast-or-famine-cycle!

Here’s another way of looking at the situation.   The plant needs the nitrogen in order to build important proteins and enzymes (also proteins), which is the same reason why we animals also need protein, for the nitrogen.  However what we really need are the amino acids, which are the molecular building blocks of protein and which on a molecular scale contain the nitrogen.  Think of it like building a brick wall, where the wall is the protein and the bricks are the amino acids.  It’s better and more efficient for a plant to build the wall with bricks that already exist rather than to need to manufacture the bricks before it can build the wall.   This is how Nature’s molecular biology of plant nutrition and soil building works, so for us its prudent to apply bio-mimicry as our method of growing any urban landscape or farm crop than it is to just crank the N-P-K into the fertilizer system.

Really! It is good news for all farmers and gardeners. Cultivation and plantation is very essential to get foods and other necessary products. There are several geographical areas where shortage of water takes place in regular basis. In such situation we can avoid this problem by suing fertilizer. This is an insightful blog and creates a benchmark in agriculture progress and development.

Understanding the Importance of Cation Exchange Capacity

I was recently asked to provide a simplified explanation on the importance of Cation Exchange Capacity (CEC) values. My Response:  CEC is the ability of a soil to hold onto plant nutrients.   The finer the particle size the higher CEC value, generally speaking. For example sand particles are course and visible to the naked eye, where as clay particles are fine and are not visible to the naked eye. So clay will have a higher CEC value than sand. It is obvious to most of us that sand cannot hold onto water or nutrients as well as a soil with a finer texture. Therefore, soils rich in Clay and Loam size particles are universally recognized as being better for farming - CEC explains this.  The numerical value for CEC represents how much nutrition can be held by a given amount of soil. For example one pound of a clay loam soil with a CEC value of 20 will hold 4 times as many nutrients as a sandy soil with a CEC value of 5. 20/4 = 5 .  It's all about math, for example Nitrogen in

Growing Pecan Trees in Western Alkaline Soil

It's common to see nutrient and water inhibition compromise the production of pecans in the arid western states, particularly where the soils are high pH, which can tie up nutrients such as zinc, iron, phosphorus and more. Keeping soils moist is also a problem because the regions were we grow pecan are not wet bottomland soils where pecan is native, but are high and dry desert soils where irrigation is essential. If the irrigation water is high in dissolved solids, the problem is made worse. There are many good things Soil Secrets can offer pecan growers that can overcome these obstacles, by improving the moisture management of the soil, improving nutrient solutioning and availability of both the native minerals as well as the purchased minerals, and improving the porosity of the soil so that water and oxygen can penetrate meters deep without the need to subsoil with machinery. How's this done? By using the power of Nature's own bio-chemical called the Carbon Matrix. Starti

Food Nutrient Density and Why our BIOpack is so important

Can you  tell the difference?  The first image shows a field that was not sprayed with your Consortium Soil Probiotic called BIOpack.  The second image field was sprayed.  Look at the difference in color and the overall biomass increase   the treated field.    BIOpack is ATCC Certified (American Type Culture Collection) and  USDA  Biobased Certified.  All 20 species included in the BIOpack are exact species that will perform a known Mode of Action which will provide a specific benefit to the crop you are growing.   For example if your lawn, trees, or crop are not getting enough iron pulled out of the soil to satisfy the needs of the crop or plant, than BIOpack can fix that problem by provided a microbe for that particular nutrient.   Bottomline is that BIOpack will improve the Nutrient Density of any crop you grow as it improves the solutioning of the mineral element in the soil from a normally not water soluble into a water solution so the plant can drink it.   This is important
