Incorporating straw boosts nutrient release, reducing need for chemical fertilizers.
The study looked at how peanut straw breaks down in soil and releases nutrients. They buried straw at different depths and measured how fast it decomposed. They found that adding more straw to the soil made it break down faster, releasing nitrogen, phosphorus, and potassium that plants need. The nutrients released from the straw can replace some of the fertilizer needed for growing wheat. The weather and the nutrients in the straw at the start were the main factors affecting how fast it broke down. Overall, adding more straw to the soil has a bigger impact on decomposition than watering it.
