Soil compaction refers to the formation of dense layers of well packed soil, often at the bottom of the cultivated
layer.The most common causes of soil compaction are tractors, harvesting equipment and implement wheels
travelling over moist, loose soils. Soils tend to be more compacted deeper into the soil profile due to the weight of
overlaying soil above.
Tractor power and weight have increased 60 - 80% since the
mid-sixties, while the tyre area in contact with the soil has only
increased on average 20%. This means that compaction is
occurring deeper in the profile, and is therefore becoming more difficult
to repair once it occurs

COMPACTION FROM TYRES IS RELATED TO
TECHNOLOGIES PVT. LTD.
Compacted soil has smaller soil pores, less pore continuity and greater strength. This makes the soil less suitable
for growing crops. The soil has fewer spaces that contain air and water needed for plant growth, is less permeable,
can store less soil water and is harder for roots to penetrate. In their virgin state soils can be productive and
characterized by excellent physical condition. They allow rapid movement of air and water through the soil,
providing an ideal environment for maximum root growth and high yields. However, soils are fragile and easily
restructured, especially during cropping. Compaction is an example of this restructuring. If compacted badly
enough, a soil does not provide adequate space for root growth and soil animal activity, or allow for rapid
movement of air and water. In severe cases, roots are unable to penetrate into deeper soil layers, tending to grow
along the top of the pan.
The best way for water and air to move through the soils is in large pores created by decaying plant roots or soil
insects and earthworms. External pressures, such as from tyres or tillage tools, cause the large pores to collapse to
form smaller pores that are less efficient conductors of air or water. The result is slower water infiltration, poor
drainage or poorly aerated soils that limit root growth and nutrient uptake needed for maximum yields. However,
some soil consolidation or "firmness" is beneficial. In very loose, uncompacted soils we could not be able to drive
over a paddock pulling an implement without becoming bogged. Firming the soil around the seed (also a form of
compaction) is necessary for creating good seed-soil contact at planting. This is why press-wheels are important
for ensuring even crop emergence. Some crops, like barley, actually seem to prefer strong seed-soil contact and a
more densely packed root zone than a very loose one. However, compaction must not be allowed to become
excessive and should be minimised in the plant root zone.
EFFECTS OF SOIL COMPACTION ON PLANT GROWTH
In some years compacted soil will affect yields, while in others it will have no impact. In seasons when there is
steady rainfall that occurs throughout the season and the optimum number of plants is established, compaction will
IMPORTANCE OF COMPACTION DETECTION AND SOIL ANALYSIS

TECHNOLOGIES PVT. LTD.
We understand the importance and significance of the soil compaction recording device and how its important for
long term soil conservation. weiber offers a unique GPS based soil compaction recorder with computer interface to
effectively record the soil compaction in real time, analyze the data and log in the data to the host computer for
detailed and comparative analysis of data taken from different locations. This equipment is a very important tool
real time soil compaction analysis and to generate computer drawing and maps of the given area.

tend not to influence yields. In other seasons, compaction can limit yields though reducing the soil’s ability to store
soil moisture or to make available stored moisture during extended dry periods. Compaction can actually increase
yields in some years, by slowing the rate of crop growth and exploitation of stored soil moisture until follow up rain
occurs. This means better use can be made of late season rainfall - particularly if the rain coincides with flowering or
grain-fill. However, the situations when this occurs are rare.
In the long-term, if compaction leads to higher rates of soil erosion than would normally occur without compaction, it
will eventually decrease the potential yield of a paddock. Similarly, if compaction becomes severe enough to greatly
restrict root activity, the number of seasons in which crops will perform well will rapidly decrease and the paddock
becomes more drought prone.
