The Thawed Strength of Soil Compacted While Frozen: An Introductory Study
In the northern United States and in Canada, expensive earthmoving equipment usually stands idle during winter months. Considerable overall economies would result if soil could be excavated, transported, and recompacted while frozen. If engineers are to accept winter operations with frozen soil, the soil after thawing should have a strength that approaches that of the same soil worked while ...

Goosegrass and Bermudagrass competition under compaction
Goosegrass (Eleusine indica L.) is a serious weed in trafficked areas of bermudagrass (Cynodon spp.) golf and sports turf. The objective of this study was to evaluate soil compaction and canopy cover as determinants of goosegrass competition in bermudagrass turf in sand soil. Goosegrass cover, plant density, and soil penetration resistance (SPR) were measured in traffic and no-traffic plots in ...

Total Suction of Artificial Mixtures of Soil Compacted at Optimum Water Content
The effect of soil composition on total suction is investigated. Thermocouple psychrometers are used to measure total suction of compacted specimens of artificial soil mixtures prepared using kaolinite, sodium montmorillonite, and a fine sand. Specimens are compacted in a Harvard miniature compaction mold at the optimum water content. The measured total suction is related to fine fraction and ...

Soil compaction, an underestimated problem
Soil compaction is becoming a major issue worldwide. Not only in the Netherlands but globally the soil is deteriorating very badly. Soil compaction is a form of soil degradation, in which the soil structure is lost because the soil is compressed. This global problem is still underestimated and causes problems for agriculture, nature, and climate. Furthermore, soil compaction leads to loss of ...

Methods of Evaluating the Expansion Potential of Compacted Soils with Significant Fractions of Large Aggregate
A laboratory investigation of the expansion potential of compacted soils with large-sized aggregate has been conducted. Methods developed for determining expansion potential include (1) laboratory expansion testing of representative specimens containing particles as large as practical and (2) prediction of expansion potential for soils with large-sized aggregate from the results of laboratory ...

Potato yield and quality response to subsoil tillage and compaction
Compacted soils have been found in intensively cultivated vegetable crop regions of Central Wisconsin, resulting in the wide scale use of subsoil tillage by growers. The goal of this project was to assess potato (Solanum tuberosum L.) yield and quality response to soil compaction and subsoil tillage. Potato quality factors evaluated were marketable yield, tuber size distribution, internal ...

Agronomic performance of different pea cultivars under various sowing periods and contrasting soil structures
Yield variability of spring pea (Pisum sativum L.) in farmers' fields is mainly due to soil compaction at sowing and abiotic stresses during the reproductive period. Winter peas flower earlier, and thus should be less sensitive to abiotic stress at the end of the cycle, but because of their sensitivity to frost they must be sown late in autumn when soils are very wet. Pea breeders are working on ...

Latest crop of robots heads for the fields
With wheels no bigger than a go-kart and a squat square chassis that weighs 200kg, the future of farm robotics looks like a midget by the standards of modern tractors. Yet the diminutive platform, called Thorvald, is the size of things to come, according to British scientists pioneering autonomous farming. Smaller robots are safer in the event of a malfunction and they do not compact the soil ...

The Relationship Between the Soil-Water Characteristic Curve and the Unsaturated Shear Strength of a Compacted Glacial Till
Soils compacted at various “initial” water contents and to various densities should be considered as “different” soils from a soil mechanics behavioral standpoint even though their mineralogy, plasticity, and texture are the same. The engineering behavioral change from one specimen to another will vary due to differences in soil structure or aggregation. The shear strength of an unsaturated soil ...

Redrow homes farnborough
Tree root protection is a task faced by many developers as they seek to provide cost-effective housing whilst preserving the surrounding environment in the face of large scale developments. A perfect example is Redrow Home’s exciting new housing project, Farnborough Central located within 2.5km of the Thames Basin Heaths Special Protection Area (SPA), a site requiring adequate measures for ...

Hardwood tree survival in heavy ground cover on reclaimed land in west Virginia: mowing and ripping effects
Current West Virginia coal mining regulations emphasize reforestation as a preferred postmining land use on surface mined areas. Some mined sites reclaimed to pasture are being converted to forests. In the spring of 2001, we compared the establishment and growth of five hardwood tree species on a reclaimed West Virginaia surface mine with compacted soils and a heavy grass groundcover. We planted ...

Tillage requirements for integrating winter-annual grazing in peanut production: plant water status and productivity
The use of crop rotation systems involving winter-annual grazing can help peanut (Arachis hypogaea L.) producers increase profitability, although winter-annual grazing could result in excessive soil compaction, which can severely limit yields. We conducted a 3-yr field study on a Dothan loamy sand in southeastern Alabama to develop a conservation tillage system for integrating peanut with ...

Monitoring Soil Health with Advanced Soil Sensor Systems
Introduction: Soil health plays a crucial role in agricultural productivity and environmental sustainability. Monitoring soil health is essential for farmers to make informed decisions about crop management practices, fertilizer application, and irrigation strategies. In recent years, advanced soil sensor systems have revolutionized the way we monitor and assess soil health parameters. This ...

Soil quality and corn yield under crop–livestock integration in Illinois
Compared with traditional cropping systems, integrated crop–livestock systems have shown greater efficiency in improving soil quality and crop yield. The objective of this study was to determine how an integrated crop–livestock system affected soil properties and corn (Zea mays L.) yield when compared with continuous corn (CC). The study was conducted from 2004–2008 on a large-scale research farm ...

How to Use Organic Fertilizer Equipment to Produce Fertilizer Suitable for Tomatoes
The application of chemical fertilizers in agricultural production can increase the yield of crops, but it will cause soil compaction, the quality of agricultural products will decline, and the nitrate content in fruits and vegetables will be too high. Bio-organic fertilizers are increasingly used in agricultural production. The organic fertilizer production equipment can combine organic matter ...

Making technology work for healthier soil
Farmers have to make decisions on which soil-health technologies they want to adopt The ‘Smart Soils’ panel at the Ag 4.0.2 conference included Jordanna Kalis from SoilOptix, Taylor Vokes from Sprucedale Agromart and Jake Kraayenbrink, owner of Agbrink. The panel was moderated by Keith Reid (r), a local farmer and the Alternative Land Use Services program co-ordinator for Grey-Bruce. ...

Three reasons the F15/F15B is ideal for fall fieldwork
As all farmers know, there’s no rest after harvest—as soon as the crops are in, it’s time to prep seedbeds for next planting season. Fall fieldwork is key to generating good emergence and yield, so it’s important to get it right. Here’s a few reasons why AMCO’s F15/F15B Double Offset Tandem Disc Harrow is the perfect tool for the job: The F15/F15B breaks up ...

Inflate, deflate tire pressure quickly from cab
The in-cab air inflation-deflation system is available for ag implements that need soft tires in the fields and higher pressure for transit. | Ron Lyseng photo No long wait times | The AAID system releases air from the tire into the atmosphere instead of back through the system GUELPH, Ont. — Soft low-pressure implement tires are best in the field. Harder higher pressure tires are ...

JXCT Soil tensiometer
A soil tension meter is an instrument used to measure the tension or suction force within soil. Soil tension, also known as soil moisture tension, is the force exerted by the soil particles as they hold water. This tension affects the ability of plants to absorb water and nutrients from the soil. Soil tension meters are important tools for irrigation management and soil research.The basic ...
