DEEP SUBSOILING OF A SUBSURFACE-COMPACTED TYPICAL HAPLUDULT UNDER CITRUS ORCHARD

Soil management practices which increase the root depth penetration of citrus are important to the longevity and yield maintenance of this plant, especially in regions where long periods of drought are common, even in soil conventionally subsoiled to a depth of 30-40 cm, when the orchard was first established.The objective of this study was to eval

The paper Monoculars represents a part from the researches referring to the tribological aspects of the brakes of the mining hoisting machines.The study consists in experimental determination of the wear intensity for the friction material in contact with rim brakes.Relying on usual theoretical considerations and experimental models, first was meas
