Farming In The Sustainable Triangle: Human, Natural and Physical Environments

Here’s a new way to visualize your goal as a farmer: “Keep your operation within the Sustainable Triangle,” advises Farm Journal Field Agronomist Ken Ferrie.

Here’s a new way to visualize your goal as a farmer: “Keep your operation within the Sustainable Triangle,” advises Farm Journal Field Agronomist Ken Ferrie.

You operate in three environments, he explains:

  • The physical environment is each farm or field’s individual properties — slope, topography, soil type, fertility, drainage, etc.
  • The natural environment is the climate and weather for your area.
  • The human environment is your ability to adapt to change, your financial resources, equipment, manpower, landlords, farm managers — and the government (which is made up of people).

Think of these environments as overlapping circles — a change in one environment affects each of the others. That overlapping area is the sustainable triangle, where you satisfy human, natural and physical requirements.


Cover Crop Decisions: Thorough Planning Increases The Odds For Success

Never is the human environment more significant than when you begin cover cropping, says Farm Journal Field Agronomist Ken Ferrie.


Real-World Cover Crop Decisions

Evaluate cropping choices on physical, natural and human factors. Let’s see how two real farmers applied sustainable triangle principles to decisions about no-till and cover crops.

Understanding your nutrient goals will keep you inside the Sustainable Triangle.


Transform Nutrient Regulations from Headaches to Opportunities

Concern about water quality has spurred nutrient reduction incentive programs and, in some cases, regulations. If you haven’t been affected by one, you probably soon will be.


Stack The Odds For Soybeans this Spring

No crop is more influenced by the natural environment (weather) than soybeans. That’s why you’ll see soybean yields vary by only 5 bu. per acre or so over a wide area, despite a range of field conditions (physical) and management practices (human).


The New Art of Hybrid Selection to Overcome Field Stresses

Choosing hybrids for their ability to overcome the stresses in individual fields is several steps removed from simply looking at neighborhood plots and talking to neighbors, says Farm Journal Field Agronomist Ken Ferrie.

Some hybrids require nitrogen early, some require it late.


How to Combat Soil’s Silent Yield Robbers

A simple step can create a major yield jump. At least that’s what a Farm Journal Test Plot study revealed. The research shows removing layers before switching to no-till can add 20 bu. to 30 bu. of corn per acre.
