Description

Uniform and wide distribution of straw and chaff residues is essential in direct seeding systems. You must spread residues evenly to avoid or reduce problems such as: equipment plugging; poor seed placement; disease, weed and insect infestations; nutrient tie-up; and cold soil under straw piles and heavy residue mats.

Description

Integrated weed management (IWM) is a sustainable cost-effective approach to weed control that is constantly evolving. The approach combines many agronomic principles to favor crop competitiveness, create diversity in cropping patterns and prevents the introduction of new weed species. Using IWM creates an opportunity to use herbicides more judiciously, increasing economic returns and slowing the development of weed resistance to herbicides.

Crop rotations in direct seeding

Description

Crop rotations are a vital part of direct seeding systems. Rotations maximize the benefits of moisture conservation and reduce the impacts of diseases, weeds and insect pests.

Description

High crop yields and unusual weather often leave hard-to-handle crop residue conditions. These include: crops not harvested due to hail, severe frost or other damage; * lodged or snow-flattened crops not picked up by the windrower or combine; crops producing heavy residues such as viny pea crops, sunflowers and flax; *very tall stubble left by straight-cut or stripper-header operations.

Description

Crop residues - straw plus chaff - are the byproducts of harvesting annual grain crops. Retaining crop residues on a field improves or maintains soil quality and moisture. The economic value of retaining or removing crop residues from the field depends on the following: present level of soil organic matter; field's soil erosion risk; nutrient levels in the residues and soil; soil's moisture content; value of using the residues for other purposes such as bedding, coarse feed or industrial uses such as fibreboard; effects of any problems caused by poorly spread or heavy residues (such as the need for extra field operations)

Description

Grasshoppers are a major pest of both cultivated crops and rangeland grasses in the world’s semi-arid regions. Traditionally drier areas like southern Alberta are more prone to recurring problems, but serious grasshopper infestations can occur in cropland throughout the province. Although the majority of grasshopper damage has been to cereal grains, other crops can be seriously affected. This fact sheet provides information on significant species of grasshoppers in Alberta, including each specie’s significant food supply. Information is also provide on grasshopper control and the economic threshold at which control measures become viable.
