Soil fertility is essential in increasing yields and profitability while supporting
sustainable agriculture production. We discuss the value of investing in an organic
soil health program which includes organic amendments, cover crops, crop rotation,
conservation tillage practices, integrated nutrient management (INM), and pH management
strategies.

Plants require various sources of nourishment – some mobile and others immobile.
The key is keeping these immobile nutrients close to the roots for maximum efficiency.

## 1. Add Organic Matter

Soil organic matter plays an integral part in supporting soil processes and plant
growth, playing an especially crucial part in global and regional cycles such as
nitrogen cycling.

Soils contain layers known as “horizons.” At the surface is topsoil, usually dark
in color with less clay content than subsoil – receiving greater climate influence
than its lower layer – known as the A horizon where maximum soil organic accumulation
takes place.

Addition of organic material to soil increases A horizons, which improve its ability
to retain nutrients. This occurs because the humus fraction of organic matter can
hold onto positively charged ions found in clay particles; thus preventing leaching
during rainstorms.

An increased presence of organic matter in soil can also help improve its structure,
leading to enhanced aggregation and permeability, thus decreasing erosion, runoff,
while creating an ideal environment for microorganisms. One effective strategy for
building up this organic matter is through reduced tillage as this reduces carbon
loss from soil while delaying decomposition of its organic matter content.

## 2. Keep Irrigation to a Minimum

Soil fertility depends on a complex web of organic matter, structure, pH and microbial
life to thrive, but when this balance is interrupted by factors like topography 
or agricultural practices or irrigation, the results can be disastrous. One key 
way to protect and enhance soil health is keeping irrigation flows as low as possible.

Overwatering damages soil structure, reduces rooting depth and increases disease,
as well as diminishing drought resistance. To maximize efficiency of irrigation 
water usage and save resources, irrigation should follow ET or crop water requirements.

An optimal irrigation and nitrogen fertilizer application strategy must simultaneously
address soil organic matter, total salt, nitrogen and pH targets while meeting high
fertility levels. We implemented this ideal strategy using a 6-hidden layer preference
neural network. For comparison purposes, we compared its performance against that
of support vector regression, linear kernel functions as well as traditional back
propagation neural networks.

As planting season arrives, now is an opportune moment to take advantage of lower
crop prices and build your soil’s nutrient reserves through an in-depth fertility
program. By conducting proper soil tests and creating an appropriate plan, you’ll
soon be on your way to reaching maximum yields and maintaining a solid bottom line
this year.

## 3. Keep Soil Moisture Levels High

Soil moisture levels are essential to plant health; too little results in poor yield
while too much can lead to root disease and wasted water. Experienced farmers can
quickly assess the moisture level in their crop’s root zone with remarkable accuracy
by simply feeling and looking at it; however, for systematic monitoring across an
entire root zone and use of this data for irrigation decisions requires measurement
devices, computers and networked communication equipment.

Soils are complex mixtures of inorganic salts, air, water and organic matter that
come together in fertile soils to provide all the essential nutrients for healthy
crops. Maintaining high soil moisture levels enables plants to access these essential
nutrients easily and increase yields.

Soil fertility depends on many factors, including topography, climate conditions,
human activities and management practices. Cultivation practices including crops,
land-use patterns and agricultural practices such as tillage, grazing and irrigation
can either improve or degrade soil fertility; deforestation reduces organic inputs
which accelerates depletion of essential nutrients while increasing erosion; excessive
use of fertilizers or pesticides also degrade soil fertility while increasing climate
risks such as drought, floods, wildfires or heatwaves – hence why implementing an
efficient steady soil moisture strategy can significantly postpone signal emergence
related to GHG-induced warming induced warming effects associated with climate risks
caused by GHG warming due to global warming effects from GHG emissions while increasing
soil moisture content can significantly postpone signal emergence associated with
GHG warming impacts that will accompany GHG-induced warming and associated climate
risks over time.

## 4. Keep Tillage to a Minimum

Soil fertility is a complex process, dependent on many variables including soil 
type and climate conditions. Fertilizer is defined as providing plant nutrients 
in sufficient amounts and form for stable crop yields year after year, as well as
protecting living organisms against diseases or pests.

Fertile soil is comprised of both macronutrients (nitrogen, phosphorus and potassium)
and micronutrients, both essential elements in terms of crop production but also
helping preserve its integrity, improve water infiltration rates and carbon storage
capabilities. Furthermore, such elements also facilitate biological processes which
recycle and reuse nutrients back into the environment.

Textured soils such as loams and sandy loams are ideal for growing crops; however,
their texture can vary across fields or even within individual fields.

Keep tillage to a minimum to improve soil fertility by limiting organic matter breakdown
and nutrient cycling, thus improving soil health. However, when making fertilizer
applications it’s essential to consider how much tillage has taken place as excessive
tillage can result in significant losses of soil carbon and phosphorus while increasing
nitrogen and phosphorus needs due to this reduction in organic matter levels.

## 5. Keep Nutrients in the Soil

As soil fertility increases, its benefits ripple throughout other aspects of crop
health and production. Soluble calcium strengthens plant cell walls while nitrogen
fuels metabolic functions that promote growth while mitigating environmental stresses
and pests. With world population expected to surge 70-100% by 2050, we must reclaim
and protect our precious soils – this means shifting to diets rich in nutrient-efficient
diets as well as intensification techniques to restore soil fertility, stability
and resilience while strengthening resilience against global change.

Soil nutrients are finite resources, and are quickly lost from an ecosystem through
intensive farming practices. Plant harvest transports these resources out, with 
insufficient nutrient returns coming back through plants or livestock to sustain
healthy soils. Degradation and depletion accelerate when we interfere with natural
balances for organic matter, soil structure, nutrients supply, pH balance and microbial
life in an ecosystem.

Start the journey toward healthy soil by beginning with a comprehensive 4R Nutrient
Stewardship program utilizing Oceanic and SeaPhos products to maintain fertile, 
functioning soil. Your test results should then be combined with this comprehensive
approach that ensures appropriate source, rate, timing, and placement of fertilizer
to maximize crop growth and yield potential. When planting season arrives, get your
fields prepared to maximize success using Oceanic and SeaPhos to build strong nutrient
banks that will support high-yield crops for years to come.

## 6. Add Fertilizer at the Right Time

Accurate fertilizer applications depend upon knowing exactly when and what nutrients
are required, and conducting a soil test can provide this insight. Based on the 
results, an accurate fertilizer application plan can then be created using this 
information.

Fertile soil contains all of the major elements necessary for plant growth – nitrogen,
phosphorus and potassium) in sufficient amounts for healthy plant growth. It also
boasts organic matter, has a pH range between 6-7 and adequate water availability.

Organic material rich with nutrients decomposes in soil to release essential elements
into solution; this process is called mineralization. However, when these elements
become tied in microbial biomass they cannot be released and thus become unavailable
to plants; this condition is known as immobilization.

Fertilizers are one of the primary tools a farmer has at their disposal for increasing
crop yield, but amending the soil should never replace sound agronomic management
practices such as crop rotations, selection of adapted varieties, tillage, cover
crops and weed control. Otherwise, using the Four R’s of Nutrient Stewardship will
minimize risks of nutrient loss while simultaneously decreasing additional input
costs.

## 7. Don’t Over-Nitrate

Farm soil conditions dictate both crop quality and quantity, so effective nutrient
management programs must include 4Rs principles – right source, right rate, right
time and right place – to optimize yield potential and ensure maximum harvest potential.
However, many factors influence soil health and fertility. Parent material and climate
have an enormous influence on soil nutrients; tillage, cropping and deforestation
alter microbial activity and physical properties; deforestation reduces organic 
matter inputs, accelerates erosion rates and disrupts nutrient cycling cycles – 
when these natural and human influences erode soil fertility, the results can be
devastating for humanity as a whole. Maintaining soil health and fertility requires
care, wisdom and stewardship by all those involved – the consequences can be immense!
