How Best to Handle Straw After Harvest?

Post-harvest handling of rice straw Which method is most effective? As AgriSearch, we understand the concept that farmers have been burning fields to treat rice straw for many years. It seemed like an easy and cost-effective solution, but scientific research shows that burning straw directly in the field actually causes more harm than good. In this article, we will delve into the negative effects of burning straw and explore more sustainable alternatives. Join us in learning more about this important topic!

The Harmful Effects of Burning Copper

Traditionally, farmers resort to burning fields to get rid of rice straw after harvesting. However, this practice has detrimental consequences for the environment and soil health.

Firstly, burning the field leads to the conversion of organic matter from the straw and soil into inorganic matter. As a result, the nutrients provided by the ash are minimal and insufficient for the field’s nutritional needs.

Furthermore, the high temperatures generated during burning cause significant water loss from the soil. Repeated and prolonged burning can result in soil degradation and compaction.

  • Impact on the Environment

Burning rice straw not only releases carbon dioxide (CO2) into the atmosphere but also emits other toxic gases such as methane (CH4), carbon monoxide (CO), and sulfur dioxide (SO2). These pollutants contribute to environmental pollution and have far-reaching consequences.

Burning a large amount of straw can cause environmental pollution

According to experts, burning one hectare of straw (equivalent to an average of 7 tons) releases 9.1 tons of CO2, 798kg of carbon monoxide, 398kg of toxic organic matter, and 12kg of ash.

  • Exhaustion of Toxic Gases Affecting Health

The combustion of rice straw produces toxic gases that, when inhaled, pose health risks. The main components of rice straw, such as cellulose and hemicellulose, generate these harmful gases. The inhalation of these gases can lead to respiratory diseases, bronchospasms, and even increase the risk of lung cancer.

  • Waste of Organic Fertilizer

Burning rice straw also results in the wastage of valuable organic fertilizer. Each ton of straw contains essential nutrients, including protein, phosphorus, potassium, silicon, and carbon. By burning the straw, farmers are depleting their fields of these nutrients, which are vital for rice production.

  • Eliminating Beneficial Insects and Natural Enemies

Burning fields not only destroys rice straw but also eliminates beneficial insects and disrupts the ecological balance. This ecological imbalance contributes to pest outbreaks in the fields, forcing farmers to use excessive amounts of pesticides to control them. Consequently, the cost of rice production increases significantly.

Burning straw at the same time kills insects, beneficial natural enemies for the field

Alternative Approaches to Handling Rice Straw After Harvesting

In light of the negative consequences associated with burning straw, scientists recommend sustainable methods for handling rice straw after each harvest.

Firstly, one effective solution is to remove all the straw from the field and utilize it to grow mushrooms. This not only provides an additional source of income but also ensures that the straw is put to good use. Additionally, the decomposed straw can be used as organic fertilizer, enhancing soil porosity and maintaining fertility.

Alternatively, if removing the straw is not feasible, plowing it back into the field can help maintain soil nitrogen levels. To facilitate better and faster decomposition of the straw without harming the rice plants, farmers can use Dascela preparations by spraying it on the straw before plowing.

Plowing and burying the straw in the soil increases organic matter content, which, in turn, aids in better root development for rice plants. Another recommended approach is to utilize straw by-products as animal feed for cattle and buffaloes.

By adopting these alternative methods, farmers can handle rice straw after harvesting in an environmentally conscious manner. Each method has its benefits, and it is crucial to assess the specific circumstances and choose the most suitable approach accordingly. Thank you for your interest in this article.

Frequently Asked Questions

1. What is the most effective method for post-harvest handling of rice straw?
Answer: According to scientists, burning straw directly in the field has caused more harm than benefits. The recommended methods include taking straw out of the field and using it to grow mushrooms or plowing and burying the straw in the soil.

2. What are the environmental impacts of burning rice straw?
Answer: Burning rice straw releases toxic gases such as CO2, CH4, CO, and SO2 into the atmosphere, contributing to environmental pollution.

3. Why is burning rice straw considered a waste of organic fertilizer?
Answer: Rice straw contains valuable nutrients like protein, phosphorus, potassium, silicon, and carbon. Burning the straw removes these nutrients, leading to a waste of organic fertilizer resources.
