What is meant by puddling in agriculture?
Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation.
What is puddling of soil?
Definition. Soil puddling for paddy rice production is the process of working saturated or near-saturated soil into soft structureless mud. Tillage in lowland rice production systems (paddy rice) is synonymous with puddling.
What is puddling and its advantages?
The benefits of puddling for rice are to control weeds, increase nutrient availability & easy transplanting. Weed control and water conservation are the most important benefit of puddling in rice. By puddling, weeds are burried in the soft soil. Puddling, decreases the water loss by percolation to a large extent.
What is used in puddling?
Tillage implements commonly used for puddling include backward inclined narrow tines, discs, powered rotary cultivators, puddlers, conical rotor, etc. In Pakistan, the tractor-operated cultivator is mainly used to puddle the fields in standing-water condition.
Who invented puddling?
Henry Cort
Henry Cort, (born 1740, Lancaster, Lancashire, Eng. —died 1800, London), British discoverer of the puddling process for converting pig iron into wrought iron. Having accumulated capital by serving 10 years as a civilian official of the Royal Navy, Cort bought an ironworks near Portsmouth in 1775.
Why is puddling done?
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 is puddling short answer?
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 write its benefits and constraints?
definition Ghildyal (1978) defined puddling as mixing soil and water to render it impervious. Puddling can be defined as the process of breaking down soil aggregates into uniform mud, accomplished by applying mechanical force to the soil at high moisture content.
What is puddling and rolling?
The process of puddling consisted in stirring the molten iron run out in a puddle, and had the effect of so changing its anotomic arrangement as to render the process of rolling more efficacious.”
What is the purpose of puddling the soil during land preparation in lowland areas?
Lowland rice fields, for example, are usually puddled to develop a hard pan and reduce water loss. Upland ricefields, on the other hand, do not necessarily have to be puddled. In resource-limiting environments, dry preparation can be adapted.
What is puddling?
the act of a person or thing that puddles. Metallurgy. the act or process of melting pig iron in a reverberatory furnace (puddling furnace ) and converting it into wrought iron. the act or method of making puddle.
What is the importance of puddling in agriculture?
Puddling (wet tillage) is done to reduce water infiltration and to maintain the standing water in the field, which helps in weed management and facilitates easier transplanting (Sharma and De Datta 1986).
What is puddling furnace?
Related to puddling: Puddling furnace pud·dling (pŭd′lĭng) n. 1. Purification of impure metal, especially pig iron, by heating and stirring in an oxidizing atmosphere. 2. Compaction of wet material, such as clay, in order to make a watertight paste.
What is soil puddling in rice farming?
Wet cultivation or soil puddling is the common soil preparation technique used for lowland rice production. Puddling breaks down, smears, and disperses soil aggregates. Soil preparation for rice traditionally requires soil puddling. Soil puddling degrades soil structure and leads to reduced infiltration rates.
