Ground cover management is the manipulation of vegetation ground cover within the orchard to maximize its benefits while minimizing its drawbacks. There are many benefits to be gained by managing the ground cover in orchards, including more rapid tree growth, earlier bearing, greater response to fertilizers, reduced tree stress during periods of dry weather, increased fruit size and yield, reduced potential for mouse injury, erosion and insulating against deep cold (frost) penetration. While total ground cover control will eliminate competition for water and nutrients, it does, however, have its drawbacks with regards to erosion, dust, frost penetration and equipment mobility during periods of wet soil conditions.
Orchard grass cover can be managed in few ways:
Each management practice/tool has some advantages and disadvantages, as you can see in the table below.
|Cultivation/hoeing||– effective, especially on small weeds|
– non-selective – controls all emerged growth
– equipment readily available
|– may damage soil structure|
– may spread perennial weeds
– may damage trees/roots
– provides only short-term control
|Mulching||– effective if properly managed|
– non-selective – suppresses all emerging weeds
– holds soil moisture as well
– provides long-term control
|– availability of mulch|
– cost of mulch/application
– attractive to rodents
– may affect tree nutrition
– must be free of weed seeds
|Mowing||– rescue treatment|
– quick suppression
– equipment available
– reduce seed spread
|– weeds may still compete|
– quick regrowth
– several mowings required
– may damage young trees
– easy to apply
– can be selective
|– require 2% soil organic matter|
– directed spray equipment
– effects on pest complex
– cost varies
Tracking of Orchard Maintenance in Agrivi System
Grass cover maintenance requires some human and machinery work, which you can record in Agrivi farm management system.
Under a crop production of certain fruit crop, you can enter all work hours of workers and machinery used in that activity. Each time when someone mows grass or spray with herbicides in the orchard, his work can be entered into that task, as well as a consumption of herbicide.
All work hours and pesticides spent on that activity you can analyze by only one click in Agrivi dashboards and print out in the form of reports.
Weeds in ground cover compete directly with the trees for needed water and nutrients during the growing season. High weed pressure can even stunt tree growth and also significantly reduce fruit size and yield per tree.
Therefore, weed management is important in crop production, as well as tracking of your farm activities with Agrivi system.
