Cadmium in soil solutions from a transect of soils away from a fertiliser bin

Environmental Pollution, 2001
The effects of high inputs of phosphate fertiliser on Cd concentrations were studied in soil solutions extracted from topsoils. Soils were sampled along a transect at distances of 1-100 m away from a fertiliser bin. The transect was sampled four times during 1 year.

Instrumented Soil Bin for Testing Soil-Engaging Tools

Applied Engineering in Agriculture, 2017
Abstract. An indoor soil bin was developed in this study for testing soil-engaging tools. The design criteria included that the soil bin had to be compact, well controlled in its operational parameters, instrumented to measure soil cutting forces, and be safe to operate. The test tool could travel at any specific speed, up to 8 km h-1.

Skidder Tire Size vs. Soil Compaction in Soil Bins

Transactions of the ASAE, 1984
ABSTRACT THE effects of tire size, inflation pressure, and percent travel reduction on bulk density were determined on ourdoor bins filled with soil from the lower Ap horizon of the Cecil, Hiwassee, and Lakeland soil series. The single-wheel tire tester of the National Tillage Machinery Laboratory at Auburn, Alabama, were used in the tests.

A Machine for Testing Tractor Tires in Soil Bins

Transactions of the ASAE, 1980
ABSTRACT THE National Tillage Machinery Laboratory (NTML) single-wheel tester has been redesigned to increase the tire-size capability and to provide electro-hydraulic servo control of the forward and angular velocities of the test wheel and the vertical load on the test wheel.

Model studies on upheaval and reconsolidation of tilled soils in a laboratory soil bin

Soil and Tillage Research, 1986
Abstract Upheaval due to primary tillage operations, generally carried out in autumn, and reconsolidation by gravity and shrinkage and by rain of a silty clay, a sandy loam and a sand soil, tilled with a rotary cultivator, a reciprocating harrow and a subsoiler, with an overall working intensity ranging from 220 to 10 m 2 m −3 and a set working ...
