Effect of soil compaction on root growth and crop yield in Central and Eastern Europe
response to soil compaction associated with soil and crop type, and soil wetness at the time of load application and weather in Central and Eastern Europe are reviewed. The effects of soil compaction on the morphological and anatomical modifications of the roots were shown. The influence of soil compaction on plasticity in root growth and functioning in relation to structural discontinuity is d...
متن کاملSoil Compaction by Valmet Forwarder Operation at Soil Surface with and without Slash
Soil compaction by machine used in forest harvesting operation caused negative impacts for regeneration and tree growth. This research was intended to analyze the effectiveness of using slash to decrease soil compaction, to analyze soil compaction at various soil depths, and to measure rut depth at soil surface. Valmet 860.1 forwarder was used in this research. Soil compaction was measured thro...
متن کاملارزیابی مقاومت تراکمی (تنش‌پیش- تراکمی) خاک با استفاده از آزمایش‌های نشست صفحه‌ای و فشردگی محصور
For prevention of soil compaction, knowledge of allowable compression stress limit (compaction strength) in soil is important. Pre-compaction stress ( σpc) was introduced as soil compaction strength and often used as a criterion for evaluation of soil susceptibility to compaction. In this research, pre-compaction stress was measured for a sandy loam soil with plate sinkage (PST) and confined co...
متن کاملSoil Compaction: How to Do It, Undo It, or Avoid Doing It
Soil compaction reduces rooting, infiltration, water storage, aeration, drainage, and crop growth. Soil compaction has been studied intensively for more than a century, and yet we still struggle with the effect that soil compaction has on crop production and the environment. In this article, we attempt to present the primary causes of soil compaction including trafficking weak soil, excessive l...
متن کاملSoil and residue management effects on arable cropping conditions and nitrous oxide ̄uxes under controlled traf®c in Scotland 1. Soil and crop responses
Soil compaction can affect crop growth and greenhouse gas emission and information is required of how both these aspects are affected by compaction intensity and weather. In this paper we describe treatments of compaction intensity and their effects on soil physical conditions and crop growth in loam to sandy loam cambisol soils. Soil conditions and crop performance were measured over three sea...
