Fall quackgrass growth.

Pre- and post-harvest weed control

Q & A with CPS

Q: When should I start weed control for my crop? A: A weed-free crop at harvest represents the cumulative effort of field management during the season. To manage many weed species, the season begins the previous fall. Pre-harvest weed control tends to focus glyphosate application on perennial weeds such as quackgrass or Canada thistle. At […] Read more

Choosing that pre-seed herbicide

Choosing that pre-seed herbicide

Q & A with CPS

Q: What are some considerations when selecting a pre-seed herbicide application? A: There are significant benefits to applying herbicides prior to seeding or crop emergence. Pre-seed weed removal reduces competition for valuable moisture and nutrients required for seedling development. When selecting pre-seed herbicides, begin with the crop to be grown. Products available vary considerably by […] Read more


High protein in HRSW

High protein in HRSW

Q & A with CPS

Q: How do I consistently achieve high protein in hard red spring wheat? What’s the optimum protein level to aim for? A: Achieving consistently high protein levels in hard red spring wheat requires annual planning as protein levels are a moving target. Begin by establishing an optimum protein goal. Generally, wheat with a protein level […] Read more

Medicago sativa in bloom (Alfalfa)

Successful forage establishment

Q & A with CPS

Q: What are the top factors for successful forage establishment? A: To grow a productive forage crop, consider important factors like soil, weeds, previous crop and herbicide residues. Identify and consider the impact of soil factors like flooding, drainage, low pH (acidity), texture and salinity that may impede establishment, productivity or species/variety selection. Control winter annual, biennial […] Read more


Growing degree days versus corn heat units

Growing degree days versus corn heat units

Q & A with CPS

Q: What are growing degree days (GDD) and how do they differ from Corn Heat Units (CHU)? A: Temperature plays a significant role in the development and maturity rate of crops. A good indicator of potential maturity is growing degree days (GDD). Corn heat units (CHU) is a measurement of cumulative heat over the growing […] Read more

Safe rates for seed-placed fertilizer

Safe rates for seed-placed fertilizer

Q: How do I determine the safe rate of seed-placed fertilizer for canola, wheat and barley? A: If you’ve bought a new drill, changed openers or changed your fertilizer blends, these changes may have implications on seed safety. Many new drills have moved to wider row spacing and narrower openers. Take the time to investigate […] Read more


Pulse and special crop production

Pulse and special crop production

Q & A with Crop Production Services

Q: What should I consider when planting my soybean crop? A: There are several important factors to keep in mind when growing soybeans. Consider your climatic conditions including heat units and moisture. Soybeans require a full season of cumulative heat to mature adequately. Varieties with maturities ranging from 2350 to 2500 Heat Units are well […] Read more

Get the best yield response

Get the best yield response

Q & A with CPS

Q: Which crop nutrients applied generally provide the most yield response in any given year? What considerations should be made? A: Crop yield response to nutrients depends on many factors. While the most important factor is moisture availability, other factors like crop selection, soil type, organic matter, residual soil fertility, previous crop, tillage, type of […] Read more
