“Stubble(Hay) Burning- A method Used by FARMERS to reduce the time between harvesting and sowing”


What is Stubble Burning?

Stubble burning is a common hone followed by agriculturists to get ready fields for sowing of wheat in November as there’s small-time left between the harvesting of paddy and sowing of wheat. Stubble burning results in the emanation of harmful gasses such as carbon dioxide, sulphur dioxide, nitrogen dioxide together with particulate matter.

Stubble Burning in North India

In North India, the onset of the winter season has come up with toxic atmospheric pollution. Crop Stubble burning pushes up the air pollution is likely to be rising this winter after rains delayed and shrank the time available for management of stubble before starting of the Rabi season.

Why Farmers opt for Stubble Burning?

Indeed, though ranchers are mindful that the burning of straw is harmful to wellbeing, they don’t have options for using them effectively.

The agriculturists are ill-equipped to bargain with waste since they cannot manage the modern technology that is accessible to handle the squander material.

Experts say that with less income due to crop damage, ranchers are likely to be slanted to light up their fields to cut costs and not spend on scientific ways of stubble administration.

Causes of Stubble Burning

  • Technology

The issue emerges due to the use of motorized harvesting which leaves a few inches of stubble in the fields. Earlier, this excess crop was utilized by agriculturists for cooking, as roughage to keep their animals warm, or indeed as additional cover for homes. But, presently the stubble use for such purposes has gotten to be outdated.

  • Adverse Impacts of Laws

Implementation of the Punjab Conservation of Subsoil Water Act (2009) made the time period of stubble burning coincident with the onset of winter in Northern India. Late transplanting of paddy amid Kharif season to anticipate water loss as directed by the PPSW Act (2009) had left ranchers with small-time between harvesting and planning the field for another crop and subsequently, agriculturists are resorting to the burning of stubble.

  • High Silica Content

Rice straw is considered futile as fodder in the case of non-basmati rice, since of its high silica substance.



Advantages of Stubble Burning

  • It rapidly clears the field and is the cheapest alternative.
  • Kills weeds, counting those resistant to the herbicide.
  • Kills slugs and other pests.
  • Can diminish nitrogen tie-up.
  • Removes residue cheaply and rapidly. If the producers penetrate or grower incorporates a difficult time going through the wheat residue, or the amount of residue is abnormally heavy, this may be an advantage.
  • Can control tan spot malady. Tan spot spores over summer on wheat residue and burning will usually kill most of the spores.

Disadvantages of Stubble Burning

  • Removes Organic Matter

Removes a major source of organic matter from the field. The residue and stubble are an imperative source of natural matter for the soil. Burning off this natural matter will steadily decrease soil natural matter levels.

  • Can solidify the ground

Burning can be made the soil hotter and drier on the surface, making a difficult seedbed.

  • Water Capacity

 Reduces water invasion capacity. Burning can incidentally seal the soil surface to a few extents.

  • Loss of supplements

 Wheat straw contains numerous supplements. Burning will result in the loss of a few of the unstable nutrients, such as nitrogen, within the residue. Minerals like Phosphorus and others are not volatilized by burning and will be on the field in the ash unless the ash is blown away. Results in smoke contamination. Air quality concerns are more prominent presently than in the past.

Solution for Stubble Burning

The excellent utilize of stubble is as an animal bolster by the change of stubble goat fodder. By changing over stubble into milk and meat will include more value than utilizing it as fuel. People cannot process straw at all, but animals like cattle, sheep; goats have four-stage stomachs that digest up to half of it. Goats have the toughest stomachs and great assimilation rates. Treatment with urea, soluble bases or molasses can create the digestibility and calorific value of straw.

Burning stubble annihilates a helpful raw fabric, contaminates the air, causes respiratory infections, and worsens nursery gas outflows. Usually, rice was gathered physically. However, today’s cultivate labor deficiency implies combine harvesters presently cut most of the Kharif crop within the north-west. Manual cutting leaves only a handful of inches of stubble, but combine harvesters leave 12 to 15 inches.

Zero-Till Cultivating is an elective that sows wheat seeds without evacuating the stubble. Tractor-mounted seeders, rotavators, and straw-reapers at the same time cut rice stubble and sow wheat seeds, then depositing the cut stubble on top as mulch. The agriculturists must be energized to adopt preservation cultivating systems. An alternative to managingpho stubble residues, primarily in high rainfall zones, are continuing to evolve. An all-around forceful approach is required for the sake of the government, researchers, and agriculturists in the shape of the adoption of ‘straw administration technologies’.
