This design has a single bead wire, which creates greater tension and uniformity in the tyre, offering more flexibility that provides the option for tyres to be run at lower pressures. However, a reading of more than 1.6g limits root growth and a 1.8g reading will severely restrict root growth, causing issues for crop yields and soil health. “Most agricultural rotations, in the absence of controlled traffic farming, traffic more than 70% of the field, where the first pass could cause 85-90% of compaction,” he reports. Measuring compaction Soil compaction can be measured using a root penetrometer and understanding of bulk density. When roots are unable to penetrate the soil, the grass will stop growing, and your lawn will start to look thin and unhealthy and become more susceptible to weeds, diseases and pests. Compaction can also be caused by wheel traffic and equipment, increasing with the amount of soil moisture. Compacted soils impede root development which can reduce yields Don’t stand or walk in your garden beds. This is a particular risk where soil cover has been damaged. For longer-lasting results, consider adding humate-rich, gypsum-based amendments to the soil.  These amendments will foster earthworm populations to support natural, biological aeration of the soil. [1] Compaction can adversely affect nearly all physical, chemical and biological properties and functions of soil. This is due to the development of horizontal layers of dense soil aggregates in the soil profile, which can lead to increased run-off, soil erosion and nutrient losses. Therefore, producers must pay more attention to soil compaction than they have in the past. Soil compaction is made worse when agricultural tyres slip – to avoid this it is essential they have good traction! This site requires a JavaScript enabled browser. “Be careful where you put weight, as this can be damaging to both soil health and machines,” says Mr Purdy. Minimising pressure per unit area on the surface is especially important, given the large size of machinery within the industry, he says. In this fact sheet we will discuss the effects of soil compaction and briefly identify ways to avoid or alleviate it. Darker soil is more porous. Retail food and drink sales hit a record £8.1bn during the 2020 Christmas period, according to the AHDB and market analyst Kantar Worldpanel. To avoid soil compaction, it is important to employ remedial measures that can contribute to better soil structure in the long term. Both have worked in the grain market field for over 20 years and will share their in-depth, specialist knowledge with you. Nature has built-in processes that reduce soil compaction, including cycles of wetting and drying, freezing and thawing, as well as plant growth and microbial activity. Use of good agronomic practices can help reduce compaction caused by wheel traffic. For larger lawns, you can use a core aerator, a gas-powered machine that will remove small plugs of soil from the ground. To reduce or minimize soil compaction: Avoid working wet soil. How to reduce soil compaction? Compacted soils can typically yield 10-20% lower than healthy soils, which is why growers could benefit from a range of measures to cut compaction risks and avoid costly yield losses. Reduce tillage . Significant soil compaction can also reduce forage yields and slow forage establishment which, in the long run, costs money. Mr Williams says that soil damage does not solely have an impact on the economics of a farm business, but can also have a negative effect on soil drainage and infiltration. This is something you must minimise because it means lower yields come harvest time. How in-depth testing helps Yorks farmer crop variable soils, Online grain trading made easy with Farmers Weekly Graindex. Addressing these issues with techniques that limit soil compaction such as optimising tyre pressure, reducing axle load and increasing organic matter levels can, therefore, help minimise soil damage. Basis points will be available for this session. You will find that reducing soil compaction is well worth the effort. Love Your Soil® will also feed soil microbes, make the soil more alive and porous, enhance root development, and offers about 25% more soil-loosening power than MAG-I-CAL® Plus. It should be able to easily penetrate at least six inches deep. Managing soil structure and avoiding degradation by building resilience is paramount. The firm’s UK agricultural sales manager Richard Hutchins explains how the company has developed novel and very high flexion (VF) tyres. Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Hard, compacted soil is a major deterrent to healthy grass growth.  Easy penetration of air and water into the ground helps roots grow deeper. Find out how to reduce soil compaction from the knowledgeable team at Jonathan Green and help your lawn flourish. Maximum soil compaction occurs when soil moisture is at or near field capacity because soil moisture works as a lubricant between soil particles under heavy pressure from field equipment. It takes just a couple of minutes to create a listing on Farmers Weekly Graindex and you’ll get a range of prices to compare from active buyers who want your grain. Learning how to improve compacted soil can make a world of difference in your lawn. Remember to hold off tillage operations until soil conditions are drier than field capacity and remember the benefits of conservation tillage systems. Compaction develops where hooves press into the soil – this is known as poaching. Fuel consumption also rises sharply when working in poor soil conditions, with fuel usage more than doubling in some situations. If the soil is very compacted, use Jonathan Green Love Your Soil®  to loosen and aerate it. This being said, compaction can still have significant negative effects on the productivity of no-till soils. Tyre pressure is dependent on the load of the machine, speed and its application, but as rule of thumb Mr Purdy recommends keeping pressure below 10psi, if tyre technology allows. Where appropriate, organic matter levels should be enhanced in order to build soil resilience to create naturally healthier soils. As with many home improvement issues, an ounce of soil compaction prevention is worth a pound of expensive roto-tilling cure. A compacted soil has a reduced … ompaction in the topsoil is dominated by tyre pressure, while vehicle axle load and weight affects compaction deeper down in the subsoil. • Soil compaction – Decrease in soil volume and porosity, or increase in soil bulk density, due to mechanical stress on soil, for example, from traffic of agricultural machinery. Such technologies can carry up to 40% more weight at identical pressures than standard radial tyres or carry the same weight at 40% lower pressure, minimising risks of soil damage while also benefiting tractor and fuel economy. Compaction can be relieved by aerating and if the cause is poor soil, top dressing with a soil amendment. To prevent soil compaction, avoid wheel traffic and tillage of wet soils; use wider tires, dual tires, or tracks; minimize tractor weight; maintain the minimum tire … Compaction is the application of mechanical energy to a soil to rearrange the particles and reduce the void ratio. Tracked Tractor vs Wheeled Tractor. How to make your own soil mix and reduce soil compaction Roots require oxygen and water for optimal growth. You can also remove a chunk of soil from the turf and dig into the soil below with a spade. Soil compaction is a common problem that many producers face but that is often overlooked. From a practical standpoint, conducting field operations at the lowest Our tires are able to support very heavy loads at very low pressure. Uncompacted soils have a bulk density measurement below 1.3g/cu cm. No-till fields are more resistant to soil compaction than deep-tilled or subsoiled fields. The company also recently introduced a digital tyre-pressure checking sensor that monitors the pressure and temperature of tyres. Nature has built-in processes that reduce soil compaction, including cycles of wetting and drying, freezing and thawing, as well as plant growth and microbial activity. Jonathan Green MAG-I-CAL® Plus is a natural, humate-rich, three-in-one “soil food” that will loosen hard soil, stimulate soil microbes, and adjust soil pH. It breaks up compacted soil for better air, water, and root penetration. “VF tyres carry 40% more load than a standard tyre at the same pressure. However, if you can’t jump on the no-till wagon just yet, there are other ways to address this problem. Soil compaction can be measured using a root penetrometer and understanding of bulk density. This will have a positive impact on water relations, aggregation, structure, carbon store, nutrient cycling and soil biology. The company’s Green Horizons scheme is designed to help…, Visit our Know How centre for practical farming advice. Wider and taller tires will carry more load per pound of inflation pressure, which decreases soil compaction. This can be achieved by optimising cultivation methods, tyre pressure and soil organic matter levels. Uncompacted soils have a bulk density measurement below 1.3g/cu cm. Soil compaction is often a major concern for many farmers as they make the risky decision to start working the field or not during the rainy spring. Soil compaction in the upper part of the soil profile is greatly influenced by the contact pressure, so lower tire inflation pressure can help reduce compaction. Otherwise, growers risk unnecessary compaction risks and additional expenditure on fuel, as broadly speaking, 1t of additional unrequired ballast equates to 1 litre of additional fuel usage per hour. “Remember that 50-60cm is the limit for which metal can be used to relieve compaction. Hold the handle with both hands while you drive it into the soil. Vehicle traffic when supplementary feeding livestock is also a common cause of soil compaction which can also lead to soil erosion. Light (or gray) soil is harder and less porous. This is effective in increasing surface permeability, but does not address compaction in deeper soil layers. Reduce soil compaction through no-till farming Naturally, farmers who practice no-till farming will find themselves in an advantageous position. Wheels vs Tracks. The principal reason for compacting soil is to reduce subsequent settlement under working loads. “Visual soil assessments are important for guiding management decisions by going out and digging holes to assess what soils need and what cultivation strategy is optimal,” he adds. Pressure in the tire is close to the average pressure exerted on the ground (example: pressure in the tire is 15 … It can also be done manually with a manual core aerator which has a handle and a foot bar with several hollow tines or spikes attached. Poor soil structure restricts root growth and limits nutrient availability, exposing crops to weed and disease attacks. However, too high pressures can cause unnecessary soil compaction. The system, named ContiPressureCheck, can be specified to new tyres or retrofitted, and provides the operator with information to prevent tyre-related issues, such as underinflation or overloading. Gypsum-based amendments will assist in natural, chemical aeration of the soil. Structural damage below this depth can cause real issues,” he warns. For the four weeks ending 27 December…, After months in the making, the government has launched its latest consultation (PDF) on the next stages of its strategy to eradicate bovine TB in England by 2038. Grass plants depend on their root systems for water and nutrients. The amount of compaction depends on the very nature of the soil, its water content, types of the crop in the soil, and the amount of load applied to the surface. Soil is most susceptible to compaction when it’s saturated and cannot absorb any more water. Another indication of compacted soil is the soil color. We see many new gardeners and garden visitors breaking this rule, so it bears repeating: do NOT stand or walk in your garden beds where you intend to grow plants! Soil specialist Mark Tripney explains how to correct soil compaction and when's the best time Correcting compaction can be done all-year-round: the best time to aerate is whenever ground conditions allow and you have the time! In soil, water and air are held in pore spaces between soil particles. Visit Jonathan Green online or visit your nearest independent retail store for reliable lawn care advice. With surveys suggesting 40-60% of UK soils are in a “moderate condition” and 0-30% “severely degraded”, there is considerable scope for the improvement of our soils, he explains. Soil compaction can quickly eat into gross margins, with losses ranging between £600/ha and £1,200/ha, explains John Williams, principal scientist at independent crop research firm Adas. The majority of soil functions are driven by biological processes, underpinned by soil organic matter decomposition. A sandy soil normally is less prone to compaction, in comparison to clay soil, which becomes very fragile in the presence of humidity; Soil structure. German tyre manufacturer Continental has recently invested in a new research and development facility in Portugal to develop tyres that help to offset the potential damage that heavy machines can cause. To find out if you have compacted soil, try pushing a screwdriver into the soil. Out-wintering and the grazing of winter forage crops can cause soil erosion and soil loss on tra… The easiest solution for soil compaction is to consider that prevention is better than cure, through the use of low-pressure vf tyres Reducing soil compaction should be a priority as it impacts your yield. If the soil is hard to get through, then you have hard (compacted) soil. Aerating your lawn regularly should be part of your lawn maintenance plan and will keep the top layer of soil loose, so your grass will get plenty of water. When the load is increased, tyre pressure is upped in order to compensate for the load carrying capacity. The product is available for acidic soil and alkaline soil and should be used every season to keep your soil biology and chemistry balanced. Use the quick field test method above to access the soil conditions, and begin planting or working the soil only if … Mr Purdy also states that machinery should not carry more weight than required for the job, aiming to keep axle weight below six tonnes.
