7. 1860 Law of the Minimum
1828 - Carl Sprengel formulates the Law of the Minimum stating that growth is limited not by the total of resources
available, but by the scarcest resource.
•Justus von Liebig (1803 - 1873) was a German
chemist who made major contributions to agricultural
and biological chemistry, and worked on the organization
of organic chemistry.
•As a professor, he devised the modern laboratory-
oriented teaching method, and for such innovations, he
is regarded as one of the greatest chemistry teachers of
all time.
•He is known as the "father of the fertilizer industry" for
his discovery of nitrogen as an essential plant nutrient,
and his formulation of the Law of the Minimum which
described the effect of individual nutrients on crops.
•The nutrient in the soil that is most deficient or “the NPK mentality”
lacking the necessary level for plant growth will be
the limiting factor for the yield of a particular crop

10. Law of the Maximum
•Elements in the soil above and beyond certain levels will
limit yields
•The prominent French chemist and farmer, Andre Voisin gets
the credit for this concept. Neal Kinsey, in his book, Hands on
Agronomy (pg. 54) states the case best; Andre Voisin...distilled
his years of research into the Law of the Maximum.
•It means that if you put on too much of a given nutrient, it is
going to tie up something else that is needed. He found that if
you put on too much potassium, it ties up boron.
•If you put on too much phosphorus, it ties up zinc and copper.
•If you put on too much nitrogen, it ties up copper and
sometimes some of the other elements, even zinc.
•If you put on too much calcium [as with over- liming], it could
tie up all the other nutrients, depending on their presence.
•Nature also invokes the law of the maximum.
“The living organism is

• Cations are positively charged ions
• Soil, clay and Humus are negatively charged
• All soils have ion sites, a nutrient holding capacity for
cations only (CEC is in milliequivalents Units or ME)
• You can fill up the sites with the good guys
• It’s called Base Saturation, the soils ratio or percentages
of nutrients held out of solution
• If your base saturation is out of balance, insects and
disease are a problem

testing method CEC Test w/Base Saturation
The test of choice for Dr. Reams and International Ag Labs is the weak acid
test. This test uses a chemical extract that was patterned after the exudates
that roots give off. It is called the Morgan Extract. The Morgan extract is a
"universal" extractant, meaning all major nutrients (including phosphorus) and
many micronutrients can all be measured in the one extract. Dr. M.F. Morgan
developed the Morgan extract in the 1930's and 40's at the University of
Connecticut.

27. Oxisol profile
Oxisols are best known for their occurrence in tropical rain forest, 15-25
degrees north and south of the Equator. The main processes of soil
formation of oxisols are weathering, humification and pedoturbation due to
animals. They are defined as soils containing at all depths no more than 10
percent weatherable minerals, and low cation exchange capacity.
Oxisols are always a red or yellowish color, due to the high concentration of
iron(III) and aluminum oxides and hydroxides. The word "oxisol" comes from
"oxide" in reference to the dominance of oxide minerals such as bauxite. In
the FAO soil classification, oxisols are known as ferralsols.
As rainfall passes through the litter on the forest floor the rain is acidified and
leaches minerals from the above soil layers. This forces plants to get their nutrition
from decaying litter as oxisols are quite infertile due to the lack of organic
matter and the almost complete absence of soluble minerals leached by the wet and
humid climate.
Oxisols are often used for tropical crops such as cocoa and rubber. In some cases, rice
is grown on them. Permanent cropping of oxisols in low-income areas is very difficult
because of low cation exchange capacities and high phosphorus fixation.
However, many oxisols can be cultivated over a wide range of moisture conditions. On
this account, oxisols are intensively exploited for agriculture in some regions which
have enough wealth to support modern agricultural practices (including regular
additions of limestone and chemical fertilizer).
Oxisols are divided into the following suborders:
Aquox - oxisols with a water table at or near the surface for much of the year
Perox - oxisols of continuously humid climates, where precipitation exceeds evapotranspiration in all months
Torrox - oxisols of arid climates. Because the present climate can never produce enough weathering to produce oxisols,
torrox soils are always paleosols formed during periods of much wetter climates. They occur mainly in Southern Africa.
Ustox - oxisols of semiarid and subhumid climates
Udox - oxisols of humid climates

30. 1. Ultisols are strongly leached, acid forest soils with relatively low native fertility.
They are found primarily in humid temperate and tropical areas of the world,
typically on older, stable landscapes.
2. Intense weathering of primary minerals has occurred, and much Ca, Mg, and K
has been leached from these soils. Ultisols have a subsurface horizon in which
clays have accumulated, often with strong yellowish or reddish colors resulting
from the presence of Fe oxides.
3. The 'red clay' soils of Palawan are examples of Ultisols.
31. Inceptisols profile
1. Inceptisols are widely distributed and occur under a wide range of
ecological settings. They are often found on fairly steep slopes, young
geomorphic surfaces, and on resistant parent materials
2. Land use varies considerably with Inceptisols.
3. A sizable percentage of Inceptisols are found in mountainous areas
and are used for forestry, recreation, and watershed.
32. Vertisols profile
1. Clay soils with unusual and interesting properties. They
cover more than 350 million hectares of land in the
world and in tropical Africa alone there are over 100
million hectares.
2. Because of their very small particle size and high
surface area, these soils have higher physical and
chemical reactivity than other soils.
3. Their interaction with agrochemicals/industrial wastes,
has been, increasingly, the subject of research
especially in the last two decades. Vertisols create
special problems when used for engineering purposes.
4. They are difficult to manage for agriculture. If they are
tilled when dry, then they can form large clods that are
difficult to break down. On the other hand, if tilled
when too wet, they smear and become impenetrable to
water and plant roots.
5. The high CEC/clay ratio suggests montmorillonitic and mixed
mineralogy. Calcium (Ca) should be the dominant cation
followed by magnesium (Mg), potassium (K), and sodium (Na)
in all the soil profiles. Meq. can range from 30-50+

Albolls — wet soils; aquic soil moisture regime with an eluvial horizon
Aquolls — wet soils; aquic soil moisture regime
Cryolls — cold climate; frigid or cryic soil temperature regime
Gelolls — very cold climate; mean annual soil temperature <0° C
Rendolls — lime parent material

Ustolls — subhumid climate; ustic moisture regime
Xerolls — Mediteranaean climate; xeric moisture regime
Soils which are in most ways similar to Mollisols but contain either continuous or discontinuous permafrost
and are consequently affected by cryoturbation are common in the high mountain plateaux of Tibet and
the Andean altiplano. Such soils are known as Molliturbels or Mollorthels and provide the best grazing
land in such cold climates because they are not acidic like many other soils of very cold climates.
Other soils which have a mollic epipedon are classed as Vertisols because the presence of high shrink
swell characteristics and relatively high clay contents takes precedence over the mollic epipedon. These
are especially common is parts of South America in the Parana River basin that have abundant but erratic
rainfall and extensive deposition of clay-rich minerals from the Andes. Mollic epipedons also occur in
some Andisols but the andic properties take precedence.take prec
Mollisols form in semi-arid to semi-humid areas, typically under a grassland cover. They are most commonly found latitudinally in a band of 50 degrees north of
the equator, although there are some in South America, South-Eastern Australia (mainly South Australia) and South Africa. Their parent material is generally
limestone, loess, or wind-blown sand. The main processes that lead to the formation of grassland Mollisols are melanisation, decomposition, humification and
pedoturbation.
Mollisosls have deep, high organic matter, nutrient-enriched surface soil (A horizon), typically between 60-80 cm thick. This fertile surface horizon, known as a
mollic epipedon, is the defining feature of Mollisols. Mollic epipedons result from the long-term addition of organic materials derived from plant roots, and
typically have soft, granular, soil structure. Mollisols occur in savannahs and mountain valleys (such as Central Asia, or the North American Great Plains). It was
estimated that in 2003, between 14 and 26 percent of grassland ecosystems still remained in a relatively natural state (that is, they weren't used for agriculture
due to the fertility of the A horizon). Globally, they represent ~7% of ice-free land area. Because of their productivity and abundance, the Mollisols represent one
of the more economically important soil orders.
Mollisols are geologically by far the youngest soil order in USA Soil Taxonomy. Their development is very closely associated with the cooling and drying of the
global climate that occurred in the past.

• There is a movement for high quality food
• High vitamins, high minerals, high sugar
• This food has healing powers
• Brixo as an indicator
• The refractometer
42.
43. The Brix Scale
A relative index of food quality
Within a given species of plant,
the crop with the higher
refractive index will have a:
•higher sugar content
•higher mineral content
•higher protein content
•greater specific gravity or
density
This adds up to sweeter taste,
Poor Average Good Excellent higher mineral density and more
nutrition as well as food with
6 8 10 12 lower nitrate and water content,
a lower freezing point, and better
storage attributes.
44. Oxygen Radical Absorbance Capacity
ORAC rating is a laboratory analysis that provides an overall measure of a
food's antioxidant activity. The higher the ORAC score, the greater is the
food's antioxidant capacity. ORAC tests are often used to compare the
antioxidant activities of different foods (fruits, vegetables, juices, wines, etc.).

55. Why Mineralize?
Silicates are necessary in building plant protein and in the synthesis of certain vitamins in
plants. Silicates function as a vital element in protecting plants against insects and fungi
attack, strengthening qualities and have been found to influence other minerals useful in
plant metabolism.
Calcium - Plants need calcium for normal cell division, as a component of cell walls, as a
component of the salts inside the cells and as a part of the genetic coding materials.
Magnesium is a key component of the chlorophylls, the green colored cells in the plant. It is
therefore vital as chlorophylls are the cells which perform photosynthesis. Also, plants need
magnesium before they can make use of phosphorous and magnesium also activates several
different enzyme systems.
Iron is a constituent of many compounds in plants that regulates and promotes growth. It
is especially important to the function of chloroplasts, the plant cells that contain chlorophyll,
which are the particles that perform photosynthesis.
Potassium strengthens plant stalks and helps undo the stress induced by excess nitrogen.
Phosphorus is the "Go" food for plants.
1. Potassium - stalk strength
2. Phosphorous - Cellular growth
3. Calcium - Insect resistance, trucker of all minerals
4. Magnesium - cell formation
5. Sulfur - N utilization
6. Sodium - Potassium pump
7. Boron - N uptake
8. Zinc - Germination
9. Copper - Anti fungal, Prevents disease
56. •Within silicate rocks are a broad spectrum of up to 100 minerals and trace elements
necessary for the well being of all life and the creation of fertile soils.
•Glacial moraine or mixtures of single rock types applied to soils create a sustainable
and superior alternative to the use of ultimately harmful chemical fertilizers,
pesticides and herbicides.
•SR has been shown in scientific studies to increase yields as much as two to four
times for agriculture and forestry (wood volume), and to have immediate results and
long term effects with a single application

60. Dr. Julius Hensel (1894)
•This book was the first work to
attack Von Liebig’s salt fertilizer
thesis.
•Translated from the German, the
book introduced people to the idea
that plants require healthy food in
order to flourish, just as a human
being does.
•It describes a then new and rational
system for fertilization which has
become science today — fertilizing
with stone dust.
•Hensel went searching for food for
plants and found it in the rocks. Fed
on such foods, plants will yield
healthy, wholesome and life
sustaining food that escapes disease
and parasites.
