IntroductionAerWay
rolling tines
Ontario-based Holland Equipment
Create pockets on the groundLow soil disturbanceReducing runoff and erosionSlide3
Objectives
Study pocket characteristics of

Site descriptionsClay loam soil
57% sand, 22% silt, and 21% clay
located in Piney, Manitoba
Sandy soil
75% sand, 18% silt, and 7% claylocated in Menisino, ManitobaSlide5

Results and discussionSlide9
Pocket opening
Clay loam
significant interaction effects
penetration depth and offset anglefor both tines, pocket length increased with a greater penetration depthpocket width increased with a greater tine offset anglethe greatest length, width, and area - 150 mm depth and 5° offset angle, regardless of the type of tine usedSlide10
Pocket opening Sandy soil not significant interaction effects
penetration depth and offset angle
pocket length was affected by penetration depth for shatter tines only
with the same penetration depth and offset angle pocket opening created by Shatter tine was greater than that created by Leaf tineSlide11
Pocket volume in the clay loam soil for different combinations of penetration depth and offset angleSlide12
Pocket volume of AerWay rolling tines in the sandy soil Slide13
ConclusionCharacteristics
of the soil pockets
varied
type of soil, type of tine, penetration depth, and offset angleShatter tines created larger pocket openings than Leaf tines
Pockets openings shorter and wider in the clay loam
soil
longer
and narrower in the sandy
soil Slide14
ConclusionThe greater penetration depth resulted in a bigger pocket opening
length
The larger offset angle increased pocket volume
Pocket volumes sandy soil smaller than clay loam soilGreater injection depth, large offset
angle, heavier soil, and Shatter tines types favour large pocket volumes and openingSlide15
