Restricted Soil

soil compaction hardpanWe all know the effects of weather - too wet, too cold, too hot, too dry; however, there are many other factors that also can affect your crop yield.  These factors are confirmed year after year by soil analysis, soil probes and net yield.  There are numerous scientific publications providing explicit scientific explanation.

Keep in mind that management decisions and cultural practice as to fertility program, crop variety, seeding rate and depth, crop rotations, straw management, weed and disease control, timing can also have an effect on crop yield.

FACT. The accumulative effect of one or more of the below listed factors will limit crop production.  The weather is changing, the natural fertility of our soils is in decline and the cost of production is increasing; therefore, it is only logical that the present way soil is managed must change.

This is the challenge that all producers face.  Using more fertilizer is not the answer. So what can be done to address these issues?

Start by learning WHY and WHAT you can do to correct soil restrictions or at least minimize the harm caused by them.  Below are some yield restricting factors that affect Canadian farmers:

Soil pH

A soil pH between 6.5 and 7.0 is found to be ideal for agronomic crops.  A pH that is outside of this range represents severe yield limiting situations for most crops.  Learn more pH and their effect on soil fertility.

Soil Salinity

The primary effect of salinity is that it will deprive your plants of water.  Salt affects plant growth because of the osmostic effect; the high salt content makes it more difficult for plants to extract the required water from the soil. Learn more about salinity and plant growth

Soil Compaction & Hardpan

The ideal ratio for crop production should contain 25% water, 25% air and 50% soil particles. The volume of water and air in the soil is referred to as pore space.  When there is a reduction in pore space, the soil density increases resulting in poor internal drainage and reduced aeration.  Find out more about the effects of soil compaction and hardpan.

Residual Chemical Effects

Glyphosate is a strong, broad-spectrum nutrient chelator that inhibits plant enzymes responsible for disease resistance so that plants succumb from pathogenic attacks. Learn more about residual chemical effects on plant growth and fertility.
