What is puddling in rice cultivation?
Puddling is wet cultivation of land that mixes soil and water to produce an impervious layer. It is achieved by plowing the flooded soil and harrowing it at progressively lower water contents. Puddling benefits rice by controlling weeds and conserving water.
What are the methods of puddling?
puddling process, Method of converting pig iron into wrought iron by subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances (see oxidation-reduction).
What is puddling and its importance?
Puddling is an important process in the field of paddy. By puddling, weeds are burried in the soft soil. Puddling, decreases the water loss by percolation to a large extent. Puddling should be done before two weeks of transplanting.
What is the effect of puddling?
Effect of puddling on soil physical properties, percolation losses and growth and grain yield of lowland rice. Puddling decreased the soil bulk density at about 1.5 times, there was a decreased in soil strength. Percolation rates dropped as well as percolation losses of water.
What are the objectives of puddling?
Purpose of puddling To reduce leaching of water or decrease percolation of water, To kill the weeds by decomposition. To facilitate transplantation of paddy seedlings by making the soil softer. To decrease water and nutrient losses by reduced hydraulic conductivity.
What puddling means?
Definition of puddling : the process of converting pig iron into wrought iron or rarely steel by subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances.
What is puddling and rolling?
Quick Reference. The process of making wrought iron from pig iron by heating and stirring it in the presence of oxidizing agents is called puddling. In 1783 and 1784 Henry Cort took From: Puddling and Rolling in The Oxford Encyclopedia of Economic History »
Why is puddling done in rice cultivation?
Puddling softens the soil and assists manual transplantation of rice seedling, minimizes water use through reduced percolation losses and effective weed control. Over time, soil puddling also creates a compacted layer below the puddled zone which further reduces percolation losses.
Which crop is used for puddling?
Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation.
What are puddles used for?
clay or the like mixed with water and tempered, used as a waterproof lining for the walls of canals, ditches, etc. verb (used with object), pud·dled, pud·dling. to mark or scatter with puddles. to wet with dirty water, mud, etc.
Who invented the puddling?
Joseph Hall
Puddling/Inventors
How was puddling invented?
Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. It was invented in Great Britain during the Industrial Revolution. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment, resulting in wrought iron.
