Humus and soil carbon
58% of Humus is carbon

Crop carbon
Exhanged carbon for yield

Crop Profitability can only be achieved by increasing true soil fertility  . .
which is . . HUMUS [soil life, health and carbon], CARBON [crop yeild and soil], WATER HOLDING CAPACITY [water, nutrient and oxygen].

Soil composting plant matter [high in Carbon] or animal matter [high in Nitrogen] produces HUMUS and SOIL CARBON, CROP CARBON and WATER CAPACITY.

The pH Farming Soil System©® produces sustainable carbon in Crop and Soil carbon.

Profit / Humus Program

Soil Fertility assessment approach for Cereal Growers:

Definition: Soil fertility is measured by the amount of humus and by the quantity, balance and type of beneficial micro-organisms present in a soil, in combination with soil nutrients.

Classification Code:

Total Cation Exchange Capacity
20 & >20 meq/100gm = A
17.5 to <20 meq/100gm = B
15 to <17.5 meq/100gm = C
12.5 to <15 meq/100gm = D
10 to <12.5 meq/100gm = E
7.5 to <10 meq/100gm = F
5 to < 7.5 meq/100gm = G
2.5 to < 5 meq/100gm = H

Cation Fertility Ratio: (15% Variation to accepted Range on Ca, Mg, and 20% on K)
Ca 58% to 78% 3
Mg 10% to 14% 3
K 4% to 6% 2
Na <3% 1
Al <3% 1
Total 10

The relationship between organic matter and a soil's fertility is best shown by the following progression:

Organic Matter
Organic matter comprises all plant and animal residues found in a soil, and provides the raw material for the formation of Humus.

Humus is the end product of the decomposition of plant and animal residues under proper environmental and biological conditions.

Soil fertility is measured by the amount of Humus and by the quantity, balance and type of beneficial micro - organisms present in a soil, in combination with soil nutrients.

Soil Activity
The twin aspects of soil fertility, nutrient range and availability, are directly affected by soil activity. Soil micro-organisms are classified into three groups on the basis of their use of nitrogen; those capable of using ammonia nitrogen, those requiring amino acids, and those requiring more complex nitrogenous (organic) compounds. Provided these nitrogens are in good supply, then plant nutrient can come from either released nutrient or applied nutrient, the presence and utilisation of both being directly affected by the level of soil activity.

Carbon Availability is essential for yield potential. The major carbon plant source comes from soil carbon dioxide and humus (58% of humus is carbon). Fulvaplex replaces carbon not found in low fertility soils (low in humus) or low in soil activity. Cation Exchange Capacity (C.E.C.) is considered the best way to measure carbon potential.
