19 Jul 2014 This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T. aman cropping system. Four different tillage practices,
Chapter 2. Influence of Soil Tillage on Soil Compaction. Barbora Badal?kova. 2.1 Definition of Soil. Soil is one of the necessary requirements for human existence and an essential component of human civilization as a whole. It is a fundamental prerequisite for agricultural production and is closely connected with food supply.
Soil water conservation through tillage is widely accepted as one of the appropriate ways of addressing soil moisture constraints in rainfed agriculture. A field experiment was conducted for 6 seasons (2007 to 2009) to evaluate the effects of 3 tillage practices namely ox-plough (OP), subsoiling-ripping (SR) and tied-ridge

ABSTRACT. A two year field experiment was conducted to investigate the effect of different tillage methods on soil physical properties and crop yield of melon. Tillage treatments in the study were moldboard plow + two passes of disk harrow as conventional tillage (CT), two passes of disk harrow as reduced tillage (RT), one
Soil tillage promotes changes in soil structure. The magnitude of the changes varies with the nature of the soil, tillage system and soil water content and decreases over time after tillage. The objective of this study was to evaluate short-term (one year period) and long-term (nine year period) effects of soil tillage and nutrient.
19 Dec 2017 Full-text (PDF) | A field experiment was conducted to evaluate the effect of different tillage systems and mulch levels on soil physical properties and growth of maize. Three tillage systems (minimum, deep & conventional tillage) and four mulch levels (control, wheat straw @ 4, 8 & 12 Mg ha-1) wer
Soil compaction of agricultural soils is a global well recognized problem (Hamza and Anderson. 2005) due to deteriorated soil environment and adverse effects of intensive use of farm machinery on crop yield (Hamza et al. 2011). In China, subsoil compaction is also caused by inappropriate tillage, traffic and field
