Causes Of Tillage Gerdiction

Tillage is the physical or mechanical agitation of the soil with tools and implements result in good tilth for better germination and subsequent growth of crops. Continuous practice of modifying the state of soil in order to provide favorable conditions for growth of crops is known as tillage addiction. Physical manipulation of soil is intended to destroy weeds, incorporate crop residues and amendments into soil, increase infiltration and reduce evaporation, prepare seedbed and break hard layers to facilitate root penetration and overcome compaction of the soil layers. Tillage enhances the decomposition of the soil organic matter by rapid microbial activity and increase aeration which helps in seed germination. Tillage addiction favors the …show more content…
The primary cause of compaction comes from heavy equipment traffic crushing air spaces out of moist soil so to avoid that compaction using mechanical power to break open that compacted layer help the plant to get aeration, nutrient uptake and root penetration beyond the compacted layer.
Fertilizer placement and application is also a reason for tillage addiction because surface applications of fertilizer can result in nitrogen loss from volatilization and cause phosphorus and other immobile nutrients to accumulate near the soil surface. so, nutrient deficiencies are likely to occur in no-till soils where crops are planted into the same row each year. So, Tillage with a chisel plow will break up soil and make the nutrients …show more content…
Continuous tilling reduces the physical properties like soil texture, soil aggregate stability, soil nutrient availability, soil water holding capacity and soil erosion by subjecting to wind and water erosion which depletes the nutrients and shows negative effect on plant growth and development. Chemical properties like Soil pH flutations and cation exchange capacity of the soil is reduced and Biological properties like disrupting the life cycle of beneficial organisms by causing physical damage to life cycle stages(larvae, pupae) of beneficial insects and loss of microbial activity. So, tillage addiction cause a severe problem by showing negative effect on soil and crop
